postback javascript error

[James]

Whenever my form postback from a dropdown control I get a javascript error stating, "Object doesnt support this property or method." I think this happens on theform.submit(); line below. Does anyone know how I can fix this problem?

function __doPostBack(eventTarget, eventArgument) {
var theform = document.Form1;
theform.__EVENTTARGET.value = eventTarget;
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}

Thanks,

James

What browser are you using? If your form is indeed called Form1, which I assume it is if the __EVENT things are set property, that line should certainly work.

IE 6.

Why are you using the doPostBack, a control that is Runat Server will Postback on its own.

 

[Robby]

Then in the form Load you can check ...

if IsPostBack then
do something
end if

I have IsPostBack in my code. Also, the reason why I am using doPostBack is because I have a dropdown control that has AutoPostBack="true" and the dropdown calls a VB sub procedure. In order for my dropdown to work I thought I was suppose to add AutoPostBack="true". The AutoPostBack adds a doPostBack function automatically. Any thoughts?

is the VB sub called before or after Postback?

 

[James]

I found my problem. I have a button control with the id="submit". For some reason the postback doesnt like buttons with the id="submit." If anyone know why please let me know.

Since the button is named submit, calling theform.submit() in the
JS you pasted refers to that control instead of the submit method
of the form like it is supposed to.
