Replace all the text occurrences in the DOM with jQuery

Question

I ma trying to write a chrome extension to replace all the specific occurrences of the text in a web page with a custom text.

I found similar questions in SO and tried the following solution but it doesn't seem to work.

   config.text_config = [
        {
            src: "Lorem ipsum",
            target: "live long and prosper"
        }
    ]
   config.text_config.forEach(function (obj) {

        $('*').each(function () {
            var text = $(this).text().replace(obj.src, 'REPLACEMENT_TEXT');
            $(this).text(text);
        })

    });

Can anyone lend me a hand here?

You can do something like, in order to be sure to replace text for all nodes:

 $(function () { $.fn.getTextNodes = function(contentText) { return $(this).find(":not(iframe)").addBack().contents().filter(function() { return this.nodeType == 3 && this.nodeValue.indexOf(contentText) != -1; }); }; var config = {} config.text_config = [ { src: "Lorem ipsum", target: "live long and prosper" } ]; config.text_config.forEach(function (obj) { var re = new RegExp(obj.src, 'g'); $('*').getTextNodes(obj.src).each(function(item, element) { this.nodeValue = this.nodeValue.replace(re, 'REPLACEMENT_TEXT'); }); }); }); 

 <script src="//code.jquery.com/jquery-1.11.3.js"></script> <div id="Message area"> <div class="selected-div"> Operation Lorem ipsum Lorem ipsum 1 </div> <div class="selected-div"> Operation Lorem ipsum Lorem ipsum 2 </div> <div class="selected-div"> Operation Lorem ipsum Lorem ipsum 3 </div> <div class="selected-div"> Operation Lorem ipsum Lorem ipsum4 </div> </div>
