Get value of div content using jquery

You can simply use the method text() of jQuery to get all the content of the text contained in the element. The text() method also returns the textual content of the child elements.

HTML Code:

<div id="box">
  <p>Lorem ipsum elit sit ut, consectetur adipiscing dolor.</p> 
</div>

JQuery Code:

  $(document).ready(function(){
    $("button").click(function(){
      var divContent = $('#box').text();
      alert(divContent);
    });
  });

You can see an example here: How to get the text content of an element with jQuery

your div looks like this:

<div class="readonly_label" id="field-function_purpose">Other</div>

With jquery you can easily get inner content:

Use .html() : HTML contents of the first element in the set of matched elements or set the HTML contents of every matched element.

var text = $('#field-function_purpose').html();
