Change form values after submit button pressed

Question

[EDIT] After a lot of digging around, I found out that the problem was in how I integrated the CKEditor into my page. The simple and obvious way does work in this c

I'm curious about your statement that the submit handler didn't work for you. It does for me. I've used it for years to fill in hidden fields before sending forms in; should work for other form fields as well.

Example (live copy):

HTML:

      Search for:
        
      

JavaScript:

window.onload = function() {

  document.getElementById('theForm').onsubmit = function() {
    var txt = document.getElementById('txtSearch');
    txt.value = "updated " + txt.value;
  };
};​

Tested and working on IE6 and IE7 on Windows, and Chrome, Firefox, and Opera on Linux.

Update: Based on your comment below, you're using jQuery. Works fine using jQuery for everything as well:

$('#theForm').submit(function() {
  var txt = $('#txtSearch');
  txt.val("updated " + txt.val());
});

Live example Tested and working on the same set of browsers. This version uses a more open search rather than an id, and also still works.
