How to get nth jQuery element

Question

In jQuery           get 3  returns the 3rd DOM element  What is the function to return the 3rd jQuery element

User · Answer

if you have control over the query which builds the jQuery object, use :eq()

$("div:eq(2)")

If you don't have control over it (for example, it's being passed from another function or something), then use .eq()

var $thirdElement = $jqObj.eq(2);

Or if you want a section of them (say, the third, fourth and fifth elements), use .slice()

var $third4th5thElements = $jqObj.slice(2, 5);

Why not browse the  short  selectors page first   Here it is  the  eq   operator  It is used just like get    but it returns the jQuery object   Or you can use  eq   function too

If I understand your question correctly  you can always just wrap the get function like so   var  someJqueryEl         myJqueryEls   get 3

You can use the  eq selector  for example      td eq 2    css  color    red       gets the third td element   Or the eq int  function      td   eq 2  css  color    red      Also  remember that the indexes are zero-based

eq   -An integer indicating the 0-based position of the element    Ex   Consider a page with a simple list on it    lt ul gt   lt li gt list item 1 lt  li gt   lt li gt list item 2 lt  li gt   lt li gt list item 3 lt  li gt   lt li gt list item 4 lt  li gt   lt  ul gt    We can apply this method to the set of list items       li    eq  2   css   background-color    red        For more information     eq

If you already have the jquery object in a variable  you can also just treat it as a normal indexed array  without the use of jquery   var all rows      tr    for var i 0  i  lt  all rows length  i        var row   all rows i        additionally  you can use it again in a jquery selector      row  css  background-color   black        Although the above example is not useful in any way  it is representing how you can treat objects created by jquery as indexed arrays

I think you can use this      ul li nth-child 2    append   lt span gt  - 2nd  lt  span gt       It finds the second li in each matched ul and notes it
