Merge the contents of two arrays together into the first array. The $.merge() operation forms an array that contains all elements from the two arrays. The orders of items in the arrays are preserved, with items from the second array appended. The $.merge() function is destructive. It alters the length and numeric index properties of the first object to include items from the second. If you need the original first array, make a copy of it before callin

Get the z-index for an element. The .zIndex() method is useful for finding the z-index of an element, regardless of whether the z-index is set directly on the element or on one of its ancestors. In order to determine the z-index, this method will start at the specified element and walk up the DOM until it finds an element that is positioned and has a z-index set. If no such element is found, then the method will return a value of 0. This method assume

Selects all next elements matching "next" that are immediately preceded by a sibling "prev". One important point to consider with both the next adjacent sibling selector (prev + next) and the general sibling selector (prev ~ siblings) is that the elements on either side of the combinator must share the same parent. jQuery( "prev + next" ) version added: 1.0

Makes the children of an element filterable. Filterable Widget The filterable widget allows you to filter the children of an element. The filtering is accomplished by applying the class ui-screen-hidden to those children for which a filter callback function provided via the widget's filterCallback option returns true. Backwards compatibility The filterable widget features provided for backwards compatibility are deprecated as of 1.4.0 and will

Selects all elements that have no siblings with the same element name. If the parent has other child elements with the same element name, nothing is matched. jQuery( ":only-of-type" ) version added: 1.9 Examples: Change the text and add a border for each button that is the only child button

Determine the internal JavaScript [[Class]] of an object. A number of techniques are used to determine the exact return value for an object. The [[Class]] is determined as follows: If the object is undefined or null, then "undefined" or "null" is returned accordingly. jQuery.type( undefined ) === "undefined" jQuery.type() === "undefined" jQuery.type( window.notDefined ) === "undefined" jQuery.type( null ) === "null" If the argument is either a primit

Selects odd elements, zero-indexed. See also even. In particular, note that the 0-based indexing means that, counter-intuitively, :odd selects the second element, fourth element, and so on within the matched set. Because :odd is a jQuery extension and not part of the CSS specification, queries using :odd cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :odd

Get all following siblings of each element in the set of matched elements, optionally filtered by a selector. Given a jQuery object that represents a set of DOM elements, the .nextAll() method allows us to search through the successors of these elements in the DOM tree and construct a new jQuery object from the matching elements. The method optionally accepts a selector expression of the same type that we can pass to the $() function. If the selector

Remove from the queue all items that have not yet been run. When the .clearQueue() method is called, all functions on the queue that have not been executed are removed from the queue. When used without an argument, .clearQueue() removes the remaining functions from fx, the standard effects queue. In this way it is similar to .stop(true). However, while the .stop() method is meant to be used only with animations, .clearQueue() can also be used to remov

Insert every element in the set of matched elements after the target. The .after() and .insertAfter() methods perform the same task. The major difference is in the syntax-specifically, in the placement of the content and target. With .after(), the selector expression preceding the method is the container after which the content is inserted. With .insertAfter(), on the other hand, the content precedes the method, either as a selector expression or as m
