2 Submit Buttons

Ron Howerton · December 21st, 2004, 11:32 AM

I have an ASP generated page that I wish to contain TWO submit buttons. The form_OnSubmit function is called automatically to validate data on the client side before the next page is called.

I would like to know which of the two submit buttons called the form_OnSubmit function because I wish to vary the QueryString accordingly. How can I tell which submit button called form_OnSubmit?

after the page is submitted check the name of the submit button. provided that the names of the buttons are unique. and then use the if , else statement.

Yes, but how do I check the name of the button? Could you provide a code example in vbscript?

Why not have a OnClick function on each button?

In the Request.Form, any element that does not exist reads like an empty string.
If you have two submit buttons with the same name, but a different face (value = ...), then that element will be equal to the face of the button clicked.

With

Code:

<form . . .>
    <submit name="btnSubmit" value="Save">&nbsp;
    <submit name="btnSubmit" value="Cancel">
</form>

at the server, if the save button is clicked, Request.Form("btnSubmit") will be equal to "Save". If there is no such element as "ab123", then Request.Form("ab123") will be equal to "".

If, on the other hand, you have

Code:

<form . . .>
    <submit name="btnSave"   value="Save">&nbsp;
    <submit name="btnCancel" value="Cancel">
</form>

and you click the save button, Request.Form("btnSave") will be "Save" and Request.Form("btnCancel") will be "".

Ah - this is exactly what I was looking for. I'd never have thought of putting a value on the button and then requesting the button's value. Thank you Brian!

And thank you Snowbelly for the link. The code there appears to be somewhat similar.

And I assume that was what Iniro was also trying to tell me.
