使用jquery检查div中是否存在文本

Question

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>

Answer 1

Here you go with a solution https://jsfiddle.net/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.com/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.com/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
