javascript - How to take the inner text of id and assign it to a specific variable only for a specific inner text -

i have different pages populate div tag specific id based on id inner text: here different example of pages div:

<div id="id_name">text page1</div> <div id="id_name">text page2</div> <div id="id_name">text page3</div> 

i want take inner text of second , fill variable.

i try use this:

if($("#id_name").length > 0 && $("#id_name").text() === "text page2") {     site.text = $("#id_name").text(); }  

1. do not use same id multiple elements. see why bad thing have multiple html elements same id attribute?
2. use classes instead
3. you can use :contains()

if ($(".class_name:contains(text page2)").length > 0) {    $('body').text("text page2");  }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>  <div class="class_name">text page1</div>  <div class="class_name">text page2</div>  <div class="class_name">text page3</div>
