[thelist] Javascript: problem writing parsed URL variable to form text box

[Robert Vreeland]

For what it is worth, my experience is that JavaScript, especially in IE, is
quirky when setting an element attribute that has not been previously
defined in the HTML code. So to be on the safe side, I would add the
attribute 'value=""' as shown below.

<input type="text" name="uP_fname" id="uP_fname" value="" />

if you have the var, its as simple as writing the following:


document.getElementById("uP_fname").value = your_var_here;



and your form should look like:

<input type="text" name="uP_fname" id="uP_fname" />


and call it in the onload method like you're doing.
