Can I call a function used OnClick without the click? 1

jofarrell · Jun 21, 2001

Being new to ASP this may sound stupid, but I have a javascript code that clears my ASP form on the click event of a button. I am just now seeing that it would be nice to be able to call it not only on the click of "Clear Form" but also when there is no data to fill into a dynamically created table and I just want the shell (Same as what my clearform does).

Is this possible?

Yes -- try this out:

First, you'll need to determine if there is no data. Easy enough, right? So let's make a variable called noData -- values 0 or 1 (1 = no data, 0 = there is data). This is obviously going to be set in your server side scripting.

Then, we'll do two things:
(1) set a global javascript variable to hold that value, so you can get at it client-side
(2) write another javascript function to check the value of that variable and then either call or don't call your function that you were (are) calling onClick of your button:

<script language=javascript>
var noData = <%=noData%>; //notice the same names for the variables, but one is ASP and one is JS

function checkForNoData(){
if (noData){
onClickFunction();
}
}
</script>

We'll just evaluate noData as if it was a boolean variable (which, in essence, it is). We'll call checkForNoData() body onLoad

<body onLoad="checkForNoData();">

And there you have it.

heh You are too good ... its amazing how complicated something as easy as a timesheet can get *grin*

But its actually starting not only look good but be functional *grin* which is a point I never thought it would get to.

Thanks again Paul
