Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto.

Zepto is open source software and is released under the developer and business-friendly MIT license. The default build includes the following modules: Core, Ajax, Event, Form, IE.

There is no Zepto. Note that some optional features of Zepto specifically target mobile browsers; as the original project goal was to specifically provide a leaner alternative to jQuery for the mobile web. Zepto is a good choice for browser extensions for Safari, Chrome and Firefox and to develop HTML-based views within native app frameworks, such as PhoneGap. In short, Zepto is expected to work in every modern browser and browser-like environment. However, for best efficiency and customizability, run the build system that comes with Zepto's source code.

It allows you to select modules, run tests, use UglifyJS to minify your custom build, and gives you an estimate on the compression that is achievable when zepto. Refer to the README for instructions on how to build Zepto, including running the tests and contributing patches. To get started with plug-in development, take a look at the source of Zepto's core moduleand be sure to read the coding style guidelines.

Create a Zepto collection object by performing a CSS selector, wrapping DOM nodes, or creating elements from an HTML string. A Zepto collection is an array-like object that has chainable methods for manipulating the DOM nodes it references. When an HTML string is given, use it to create DOM nodes.

If an attributes map is given via argument, apply them to all created elements. When a function is given, attach it as a handler for the DOMContentLoaded event. If the page is already loaded, executes the function immediately.

This allows you to use Zepto with legacy code that uses, for example, Prototype. Zepto will always set the Zepto global to itself. Iterate over array elements or object key-value pairs. Returning false from the iterator function stops the iteration.

Extend target object with properties from each of the source objects, overriding the properties on target. By default, copying is shallow. An optional true for the first argument triggers deep recursive copying. Adding a function to this object makes that method available on every Zepto collection. True if the object is a window object.

Iterate through elements of collection and return all results of running the iterator function, with null and undefined values filtered out.

Get string type of an object. To find out if an object is a plain JavaScript object, use isPlainObject. Modify the current collection by adding the results of performing the CSS selector on the whole document, or, if context is given, just inside context elements. Add class name to each of the elements in the collection. Multiple class names can be given in a space-separated string.

Add content to the DOM after each elements in the collection. The content can be an HTML string, a DOM node or an array of nodes. Append content to the DOM inside each individual element in the collection. Append elements from the current collection to the target element. This is like appendbut with reversed operands. Read or set DOM attributes. When no value is given, reads specified attribute from the first element in the collection.

When value is given, sets the attribute to that value on each element in the collection. When value is null, the attribute is removed like with removeAttr. Multiple attributes can be set by passing an object with name-value pairs.

To read DOM properties such as checked or selecteduse prop. Add content to the DOM before each element in the collection. Get immediate children of each element in the current collection. If selector is given, filter the results to only include ones matching the CSS selector. This method doesn't have an option for copying data and event handlers over to the new elements, as it has in jQuery. Traverse upwards from the current element to find the first element that matches the selector.

If context node is given, consider only elements that are its descendants. This method is similar to parents selectorbut it only returns the first ancestor matched. If a Zepto collection or element is given, the resulting element will have to match one of the given elements instead of a selector. Modify the collection by adding elements to it.

If any of the arguments is an array, its elements are merged into the current collection. Read or set CSS properties on DOM elements.

When no value is given, returns the CSS property from the first element in the collection. When a value is given, sets the property to that value on each element of the collection.

Multiple properties can be retrieved at once by passing an array of property names. Multiple properties can be set by passing an object to the method. When a value for a property is blank empty string, null, or undefinedthat property is removed. Behaves like attrbut prepends data- to the attribute name. When reading attribute values, the following conversions apply: To store arbitrary objects, include the optional "data" module in your custom build of Zepto. Iterate through every element of the collection.

Inside the iterator function, this keyword refers to the current item also passed as the second argument to the function.

If the iterator function returns falseiteration stops. Filter the collection to contain only items that match the CSS selector. If a function is given, return only elements for which the function returns a truthy value.

Inside the function, the this keyword refers to the current element. If a Zepto collection or element is given, filter those elements down to only ones that are descendants of element in the current collection. Get all elements or 101 livestock auction market report single element from the current collection. When no index is given, returns all elements in an ordinary array.

When index is specified, return only the element at that position. This is different than eq in the way that the returned node is not wrapped in a Zepto collection. Filter the current collection to include only elements that have any number of descendants that match a selector, or that contain a specific DOM node.

Get the height of the first element in the collection; or set the height of all elements in the collection. Hide elements in this collection by setting their display CSS property to none. Get or set HTML contents of elements in the collection. When no content given, returns innerHTML of the first element. When content is given, use it to replace contents of each element.

Content can be any of the types described in append. Get the position of an element. When no element is given, returns position of the current element among its siblings. When an element is given, goventure stock market simulation software its position in the current collection.

Returns -1 if not found. Get the position of an element in the current collection. If fromIndex number is given, search only from that position onwards. Returns the 0-based position when found and -1 if not found. Use of index is recommended over this method. Insert elements from the current collection after the target element in the DOM.

This is like afterbut with reversed operands. Insert elements fastest way to make money in apb reloaded as an enforcer the current collection before each of the target elements in the DOM. This is like beforebut with reversed operands. Check if the first element of the current collection matches the CSS selector.

Iterate through all how does retail forex trading work and collect the return values of the iterator function. Returns a collection of results of iterator function, with null and undefined values filtered out. If another collection is given instead of selector, return only elements not present in it.

If a function is given, return only elements for which the function returns a falsy value. Get position of the element in the document. Returns an object with properties: When given an object with properties left and topuse those values to position each element in the collection relative to the document. Get immediate parents of each element in the collection. If CSS selector is given, filter results to include only ones matching the selector.

Get all ancestors of each element in the collection. To get only immediate parents, use parent. To only get the first ancestor that matches the selector, use exchange rates in karachi open market. Get values from a named property michael jenkins stock market each element in the collection, with null and undefined values filtered out.

Get the position of the first element in the collection, relative to the offsetParent. This information is useful when absolutely positioning an element to appear aligned with another. Prepend content to the DOM inside each element in the collection.

Prepend elements of the current collection inside each of the target elements. This is like prependonly with reversed operands. Read or set properties of DOM elements. This should be preferred over attr in case of stocks and shares isa good investment values of properties that change with user interaction over time, such as checked and selected.

Short and lowercase names such as forclassreadonly and similar will be mapped to actual properties such as htmlForclassNamereadOnlyetc. Remove elements in the current collection from their parent nodes, effectively detaching them from the DOM.

Remove the specified attribute from all elements in how much money does gary bettman make collection. Multiple attributes to remove can be passed as a space-separated list.

Remove the specified class name from all elements in the collection. Remove a property from each of the DOM nodes in the collection. What stock is warren buffett buying today each element in the collection—both its contents and the element itself—with the new content.

Content can be of any type described in before. Gets or sets how many pixels were scrolled to the right so far on window or scrollable element on the page. Gets or sets how many pixels were scrolled down so far on window or scrollable element on the page. Get all sibling nodes forex cargo balikbayan box each element in the collection.

If CSS selector is specified, filter the results to contain only elements that match the selector. Extract the subset of this array, starting at start index. If end is specified, extract up to but not including end index. Make real money playing mmorpg or set the text content of elements in the collection.

When no content is given, returns the text contents of all the elements in the collection, if no element exists, null will be returned. When content is given, uses it to replace the text contents of each element in the collection. Toggle between showing and hiding each of the elements, based on whether the first element is visible or not. If setting is present, this method behaves like show if setting is truthy or hide otherwise.

Toggle trading on the frankfurt stock exchange class names space-separated in each element in binary stock trading websites collection.

If setting is present, this method behaves like addClass if setting is truthy or removeClass otherwise. Remove immediate parent nodes of each element in the collection and put their children javascript append select list their place. Basically, this method removes one level of ancestry while keeping current elements in the DOM.

Get or set the value of form controls. When no value is given, return the value of the first element. When a value is given, set all elements to this value. Get the width of the first element in the collection; or set the width of all elements in the collection. Wrap each element of the collection separately in a DOM structure.

Structure can be a single element or several nested elements, and can be passed in as a HTML string or DOM node, or as a function that is called for each element and returns one of the first two types.

Keep in mind that wrapping works best when operating on nodes that are part of the DOM. When calling wrap on a new element and then inserting the result in the document, the element will lose the wrapping. Wrap all elements in a single structure. Structure can be a single element or several nested elements, and can be passed in as a HTML string or DOM node. Wrap the contents of each element separately in a structure. Create and initialize a DOM event of the specified type.

If a properties object is given, use it to extend the new event object. The event is configured to bubble by default; this can be turned off by setting the bubbles property to false. Get a function that ensures that the value of this in the original function refers to the context object. In the second form, the original function is read from the specific property of the context object.

If additional arguments are passed beyond the 2nd argument, they are applied to every invocation of the wrapped function in front of its actual arguments. Attach an event handler that is only triggered when the event originated from a node that matches a selector.

Returns true if preventDefault was called for this event instance. This serves as a cross-platform alternative to the native defaultPrevented property which is missing or unreliable in some browsers.

Returns true if stopImmediatePropagation was called for this event instance. Detach event handlers added with on. To detach a specific event handler, the same function must be passed that was used for on. Otherwise, just calling this method with an event type will detach all handlers of that type.

When called without arguments, it detaches all event handlers registered on current elements. Add event handlers to the elements in collection. Multiple event types can be passed in a space-separated string, or as an object where event types are keys and handlers are values. If a CSS selector is given, the handler function will only be called when an event originates from an element that matches the selector.

If the data argument is given, this value will be made available as the event. Event handlers are executed in the context of the element to which the handler is attached, or the matching element in case a selector is provided. When an event handler returns falsepreventDefault and stopPropagation is called for the current event, preventing the default browser action such as following links. Adds an event handler that removes itself the first time it runs, ensuring that the handler only fires once.

Trigger the specified event on elements of the collection. If an args array is given, it is passed as additional arguments to event handlers. Perform an Ajax request. It can be to a local resource, or cross-domain via HTTP access control support in browsers or JSONP. This has the limitation of contentTypedataTypeheadersand async not being supported.

Provides access to the xhr object and allows changing the settings. Return false from the function to cancel the request. These methods supersede the successerrorand complete callback options. These events are fired during the lifecycle of an Ajax request performed with the default setting of global: By default, Ajax events are fired on the document object.

However, if the context of a request is a DOM node, the events are fired on that node and will bubble up the DOM. Object containing the default settings for Ajax requests. The ones that are useful when set globally are:. Get JSON data via Ajax GET request. Serialize an object to a URL-encoded string representation for use in Ajax request query strings and post data.

If any of the individual value objects is a function instead of a string, the function will get invoked and its return value will be what gets serialized. Set the html contents of the current collection to the result of a GET Ajax call to the given URL.

Optionally, a CSS selector can be specified in the URL, like so, to use only the HTML content matching the selector for updating the collection:.

Serialize form into an array of objects with name and value properties. Trigger or attach a handler for the submit event. Change existing values or add new properties to affect animations that use a string for setting duration. Zepto also supports the following CSS transform properties:. If the first argument is a string instead of object, it is taken as a CSS keyframe animation name. Zepto exclusively uses CSS transitions for effects and animation.

See the spec for a list of animatable properties.
