I would like to check if the text exist in the div element, so that if text matches the text in div it will alert "hello". May I know how am I able to achieve this result? Thank you.

  <script type="text/javascript">
    jQuery(document).ready(function(){
        var text = "div[style*=\"width: 550px;\"]";
        if (#content.indexOf(text) > -1){
            alert("Hello");
        }
    });
  </script>
  <div id="content">
    <div style="width:550px;">James</div>
    <div style="width:500px;">Amy</div>
  </div>

• Open you browser console. You will see an error like this "Uncaught SyntaxError: Invalid or unexpected token" Which seems to be pointing to this line (#content.indexOf(text) > -1) – NewToJS Commented Oct 23, 2017 at 3:04
• The "text" you are searching for is part of the HTML source, not part of the DIV's text content. Your text variable contains a CSS/jQuery style selector, not the actual string you want to search for. – nnnnnn Commented Oct 23, 2017 at 3:07
• are you trying to check if a div contains style="width:550px;" ? – user5525667 Commented Oct 23, 2017 at 3:32

Here you go with a solution https://jsfiddle/9kLnvyqm/

if($('#content').text().length > 0) {  // Checking the text inside a div

  // Condition to check the  text match
  if($('#content').text().indexOf('Amy')){
  	console.log('Hello');
  }

}

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="content">
  <div style="width:550px;">James</div>
  <div style="width:500px;">Amy</div>
</div>

If you want only the text content from a container then use text(), if you are looking for html content then use html().

Hope this will help you.

It is possible to get the value of inline style of an element.

var wid = $("#content > div")[0].style.width;
if(wid === "550px"){
  //correct width detected. you can use alert instead of console.log
  console.log("hello");
}

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="content">
  <div style="width:550px;">James</div>
  <div style="width:500px;">Amy</div>
</div>

You have multiple elements inside #content. you may want to use the return value of

$('#content').children().length;

and loop the program to get inline width of all elements. Ping if you need some help with the loop
