jQuery .index() return index value for DOM element. Syntax and Description . index() accepts a DOM element, and returns its zero-based index value. 20 Jul 2009 jQuery has become one of the defacto JavaScript libraries for web devs. ABT discusses a quick top on finding the current index position of a Examples index. One of the best ways to learn how to do anything new (including software APIs!) is to get your hands dirty as quickly as possible. With this method we can filter our jQuery object with the aid of two indices, the starting and ending position. The element at the ending index is not included,
If no argument is passed to the .index() method, the return value is an integer indicating the position of the first element within the jQuery object relative to its sibling

Please help to solve this problem, thank you in advance. $('.image_or_video' .index() is a method on jQuery objects that's generally used to search for a given element within the jQuery object that it's called on. This method has four different signatures with different semantics that can be confusing. This article covers details about how to understand the way .index() works with each signature.. link.index() with No Arguments The index() method returns the index position of specified elements relative to other specified elements. The elements can be specified by jQuery selectors, or a DOM element. Note: If the element is not found, index() will return -1. Recently had many tutorials where it was the case to use the jQuery $(this) selector and couldn't find any official documentation about it. Therefore in this article I want to cover a full explanation with some good examples, so everyone can understand what this thing does exactly and where you must use jQuery $(this) selector. The first argument to your .each() callback function is the index of the current iteration of the loop. The second being the current matched DOM element So: The second being the current matched DOM element So: And I have this jQuery: $("#wizard li").click(function { // alert index of li relative to ul parent }); How can I get the index of the child li relative to it's parent, when clicking that li? For example, when you click "Step 1", an alert with "0" should pop up. Given a jQuery object that represents a set of DOM elements, the .eq() method constructs a new jQuery object from one element within that set. The supplied index identifies the position of this element in the set. Consider a page with a simple list on it:

Each jQuery object also masquerades as an array, so we can use the array dereferencing operator to get at the list item instead: 1 console.log( $( "li" )[ 0 ] ); The eq( index ) method reduces the set of matched elements to a single element. Syntax. Here is the simple syntax to use this method − selector.eq( index ) Parameters.
