[resolved]document.Form

[jewel]

I need to get the value of a form element by using

document.Form1.txtName.value

I get an error when I use this on a web user control...

So I tried putting form tag in the html code still, it doesn't work dunno why, maybe its because I didn't put runat="server" but if I put this the page will return an error saying that it cannot allow two runat="server"

anyone?

Please help...


Thanks,

Take a look at txtName's ID attribute when viewing the page in a browser. It has most likely changed when being rendered.

how?

Open page in browser (run application) then in your browser, Edit > View Source.

Either look in the HTML source as Mendhak says or you can access the client-side ID of a control from the ClientID property i.e. txtName.ClientID

hi, yes it changed it to MyControl1:sName because I embedded it as a web user control with name MyControl1, so I used this in the script

alert (document.all["MyControl1:sName"].value );

however this will be a problem when I reuse the control under a different name...

any other suggestions?

Thanks,

Generate your javascript from codebehind and use controlname.ClientId in there.

[jewel]

do you mean generate javascript from codebehind then use RegisterStartupScript? but this is not available for user control, right?

hmmm...


Thanks,

This works

Dim strScript As String = "alert (document.all['" & MyClass.ClientID & "_sName'].value );"
        btnOk.Attributes.Add("onclick", strScript)

Thanks,

I wont put resolved yet coz i don't know if another problem would sneak in...
