Question

Javascript form submital works in webkit, fails elsewhere

Answer 1

A:

That should work across browsers.But actually I just think you need a window.setTimeout here with a value of 0. What's happening is that you're trying to access an element before JavaScript has a time to "breathe"

Try:

window.setTimeout( function() { 
        myForm.submit();
        document.body.removeChild(myForm);
}, 0 );

I assume you mean replace the last two lines of the method with that code? I tried it, but then it ceases to work even in webkit. Maybe I should add that the way it's working is that I'm using the script as a href in my anchor tags. So when you click on the link it passes the parameter through the post to the same page, updating the content.

Answer 2

+1 A:

It works for my Firefox 2, Chrome 2. Here is my complete test page:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <script>
    function posturl (url) {
        var myForm = document.createElement("form");
        myForm.method="post";

        var myInput = document.createElement("input") ;
        myInput.setAttribute("name", "url") ;
        myInput.setAttribute("value", 'http://www.google.com');

        myForm.appendChild(myInput);
        document.body.appendChild(myForm);
        myForm.submit();
        document.body.removeChild(myForm);
    }
    </script>
</head>
<body>
<input type="button" value="posturl()" onclick="posturl()" />
</body>

There must be something else (possibly related to opening blank tabs?? WTF?) that is breaking your code.

Here's why it doesn't work in IE.

Thanks. I ended up fixing my problem by changing the javascript function call from being inside a href to replacing it with an onclick. That did the trick, seemingly. I guess the issue wasn't with the script after all :)

@Jarsen: you'll find IE still screws it up. See the link I posted.
