custom javascript validation for form

[playout]

Hi, I am having problems firing a javascript function on an asp.net page. I add the onclick event to the button, but the event does not fire. Here is my code: VB btnSubmit.Attributes.Add("onclick", "val_update(" & Me.drpLocations.ClientID.ToString & "," & Me.drpStatus.ClientID.ToString & "," & Me.txtUserLoginName.ClientID.ToString & "," & Me.Form.ClientID.ToString & ");") ASPX var msgInvalid = "Not validated" function val_update(valLocation, valStatus, valUser, valForm){ if (valStatus.selectedIndex == 2 && valLocation.selectedIndex == 0) { msg = "You need to add a Location" alert(msg); return false; } if (valUser.value = "") { msg = "You need to add a UserName" alert(msg); return false; } else { alert(msgInvalid); return false } } 'button here - normal button with ID, runat command, and text. Every time I click the button, the else statement gets processed, and "Not fired" is alerted. Not sure what I am doing wrong. Is there any way how I can do the above validation client-side?

Use the document.getElementById method to get the elements from their id.

--- b { font-weight: normal; }

I am not to sure how to do that, as the asp.net gives my textboxes and dropdown boxes different names to the names I specify in the asp.net. EG. My txtfield is called "txtUserLoginName", but when I view source, it's called "ctl00$cphCenter$txtUserLoginName"

But you already do that in the code. The problem is that you are treating the id strings as variable names instead of strings in the Javascript code.

--- b { font-weight: normal; }

I found the problem, thanks. Got it to work now. Thanks for the help. If you didnt point it out to me, I would probarly still be sitting clueless.

you are doing correctaly but you need to be get values in function instead of passing in function. like getElimentbyId('<% drpLocations.ClientID %>') then use it.
