    frankmoore Converting a jQuery object back to a JavaScript String

    jQuery noob here, so I apologize in advance if this question has been asked before.

    My situation is this: I have a string of HTML that I've extracted from my document and passed into jQuery to manipulate as such:

    Code:
    var pageEl = document.getElementById("ElementId");
    var contentToProcess = pageEl.innerHTML;
    
    // pre-process contentToProcess...
    
    var jQueryContent = $(contentToProcess);
    
    // process elements using jQuery methods
    Now, I've completed the processing that I wanted to do using jQuery and I need to extract the processed content from the jQueryContent object. How do I do this?

    There was a helpful post on stackoverflow, but the solution that they outlined isn't working. Does anyone else have any experience with this?

    Thanks.

    if you going to use jquery you can use it all the way so instead of doing

    var pageEl = document.getElementById("ElementId");
    var contentToProcess = pageEl.innerHTML;

    you can do

    var contentToProcess = $('#ElementId').html();

    example how you can do what you want if ii understand you correctly

    Code:
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <html lang="en">
      <head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
    <script type="text/javascript">
    $(function(){
    var content = $('<div><p>one</p><p>two</p></div>');
    // do some operations
    content.find('p:first-child').remove();
    // create a container to append your conmtent
    var container =  $('<div/>');
    //append the content to the container
    container.append(content);
    // if you dont append the content to a container you do not get the parent tag (<div></div>)
    alert(container.html());
    });
    </script>
        <title>Test</title>
      </head>
      <body>
        <p>Test</p>
      </body>
    </html>

    Gozzy, thanks but I already tried that approach. Unfortunately, the .html() method only returns the innerHTML of the object which, in Firefox, does not reflect changes which have been made using JavaScript.

    I think I have a work-around to my a problem, however, it involves going back to DOM methods and removing jQuery entirely.

    Use .get(0) instead of .html()
