not sure what you mean by <<this code cannot be changed, but I will assume that you mean you cannot attach an event handler to that button, is this case, you can use the OnSubmit() event of the form to access this hidden field and set its value.


<script>
function dosomething()
{
document.forms["myform"].pid.value = "whatever I want";
}
</script>

<form name="myform" onSubmit="dosomething();">

<input type="hidden" name="pid" value="updateItem" />

<input type="submit" value="Delete Item" />

</form>

I am not sure if I understand, but I suppose you want to change the value of the hidden tag by a button push. In this case, you can do it in the following way:

<script>
function change_value(value)
{
document.forms["myform"].pid.value = value;
}
</script>

<form name="myform" onSubmit="dosomething();">

<input type="hidden" name="pid" value="updateItem" />

<input type="submit" value="Delete Item" />

<button onClick="change_value('first_value');">First button</button>
<button onClick="change_value('second_value');">Second button</button>

</form>

The above code uses ordinary buttons (no input tags, hance you can't use the onClick handler for them) to change the value of the hidden tag.

Good luck.
