Convert <li> element to an array

  • If we want to convert the <li> elements to an arrray, then it we can use JQuery.
  • In this context we will use toArray() to count the elements in JQuery Selector.

Syntax

<script type="text/javascript">

    $(document).ready(function () {

        $("button").click(function () {

            x = $("li").toArray()

            for (i = 0; i < x.length; i++) {

                alert(x[i].innerHTML);

            }

        });

    });

</script>

Lets take an example

<!DOCTYPE html>

<html>

<head>

    <script src="jquery-1.7.2.min.js" type="text/javascript"></script>

<script type="text/javascript">

    $(document).ready(function () {

        $("button").click(function () {

            alert($("li").size());

        });

    });

</script>

</head>

<body>

<button>Count The Number Of Student</button>

<ol>

<li>Aman</li>

<li>Nitin</li>

<li>Prabhakar</li>

<li>Styaprakash</li>

<li>Vipin</li>

<li>Shubham</li>
