Java Script Validation

[hoz]

Hi ,
I am developing an web application . I have a form for user login ,contains
two textboxs . How can i check them if these are empty using client side
validation ?
But i want it like below
<script lang="..... >
function Validate()
{ if ( this.forms.userTxt=="")
return false ;
....
}
</script>

the button is server side , how can i add , when clicked first goto Validate
and then execute button_click() ?

Button.Attributes.Add ("onClick", "return Validate();")

Your Validate() function should return true if postback should occur, false
to stay.

Another option is to use the RequiredFieldValidator control (one for each
text box).

Hello hoz,

Look at the asp:RequiredFieldValidator control. This handles everything for
you. You dont need to write any javascript.
