The src file of my iframe has 3 textboxes. Entering 2 values in the first 2 textboxes displays the sum in the 3rd textbox. The sum calculation AND display is done using javascript inside the src file. Frame1.contentWindow.document.body.innerHTML in Firefox gives the src file's content and not the updated content (that is, with the values in the textboxes). Is there a way to access the 'updated' iframe content?
