Validate before JScript

[Peter]

ASP.NET 1.1

I have WebForm button with JScript, but I want to validate the form before
the JScript runs when the user clicks on the button, how to I do that?

this.butCreateLetter.Attributes.Add("onClick", "return CreateLetter();");



Thank You

You pretty much have to output the javascript you want to run inside your
button's event handler.

this.butCreateLetter.Attributes.Add("onClick", "if
(typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); return
CreateLetter();");

this.butCreateLetter.Attributes.Add("onClick", "if
(typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); return
CreateLetter();");

Thank You very much.

I have one more question

If validation fails how do I stop it from running the CreateLetter()
function?


Thanks

that'll only work for client-side validation. Ie, it won't work in firefox..

yes I am aware of it, this webpage is for Intranet and this webpage uses
ActiveX to open Word template so user has to use IE.

I have found the solution to stop executing JScript when validation fails:

System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("if (typeof(Page_ClientValidate) == 'function') { ");
sb.Append("if (Page_ClientValidate() == false) { return false } else {return
CreateLetter(); }} ");


Thank you for all the help!!!

I thought that was what he wanted.

Hmmm...works for me using this FF version:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051111
Firefox/1.5

....however, I just realized that I'm using 2.0 and he mentioned 1.1. Would
this be the difference?

It works in 1.1 just as well

Yes, validators in 1.1 won't work in Firefox, in 2.0 they do (client-side
that is).

Looks like you are right, IE only on an intranet..though I see no where in
the original post where that was stated lucky guess
