Answer 1

A:

Why don't you add a button using JavaScript when the response is shown to the screen?
This way should work on all browsers...

function addButton() {  
    //Create an input type dynamically.  
    var element = document.createElement('input');  

    //Assign different attributes to the element.  
    element.setAttribute('type', 'button');  
    element.setAttribute('value', 'Continue');  
    element.setAttribute('name', 'somename');  
    element.setAttribute('id', 'someid');  

    var foo = document.getElementById("fooBar");  

    //Append the element in page
    foo.appendChild(element);  
}

Thanks for your reply Dror. The problem is the above message(from external security manager-sitemeinder) is shown when the session expires.Otherwise some search results are shown. I need to check if the response contains certain fields, then append the element as you told. But this makes the application tightly binded with SiteMinder.

The reason why the form is not displayed inside the table is, we don't have tr and td tags. If I add those tags the form is getting displayed.

glad to hear you got around this - write down your answer and accept it for reference to other people that might need your work-around.

Answer 2

+1 A:

Your generated DOM is invalid. Character data (text) and <br>, <form> and <script> elements may not be child elements of elements - only <tbody>, <thead> and <tfoot> element may (although in XHTML you can have <tr> elements too).

For those elements to exist inside a table, they must appear entirely within a table cell.

Given broken HTML, Firefox will do a good job of compensating for author errors, but when the broken DOM is generated with JS, you bypass some of the autocorrection routines.

As an aside, your Doctype (HTML + Transitional + No system identifier) triggers Quirks mode - which doesn't generally help matters.

I suggest:

Switch to a Doctype that triggers Standards mode
Validate your markup
Build the content you are adding with JavaScript using plain HTML instead
Make that validate
Write JavaScript to generate the DOM you have now tested as being valid
