Hi all,
I have a problem invoking a Java Script function inside a
href function. I've to pass the return value of a java script function
as an input to the script which is invoked using href in anchor tag.
The problem is the function is not getting invoked. Here is my code:

<a class="innerliks_sub1" href='/ems/cgi-bin/wips/wips_dashboard.cgi?
current_time='+Math.round(new Date().getTime()) target="icc"
onClick="sethelplink('dashboard')"> Dashboard </a>


Can some one help me how to pass the value to that cgi? Pls let me
know if you need any clarifications.

It is either JavaScript or ECMAScript. And there is no "href function".

What does the click listener do? And the attribute is properly spelled
"onclick". (Why one needs to submit some date/time via an URI to a
server is beyond me, anyway.)

Untested:
<a ... href='/ems/cgi-bin/wips/wips_dashboard.cgi'
onclick="
if(sethelplink('dashboard')) {
this.href = this.href +
'?current_time='+Math.round(new Date().getTime();
return true;
}
">

If "JavaScript" is understood as a name for all ECMAScript implementations.

ACK

Isn't that a bit too much to assume here?

this.href +=

You forgot the closing `)', but Math.round() does not make sense here
in the first place. And fast history navigation might turn this into
something really wrong.

With less assumptions, a bit more efficient and less error-prone:

<a ... href="/ems/cgi-bin/wips/wips_dashboard.cgi"
onclick="this.href = this.href.replace(/\?.*/, '')
+ '?current_time=' + (new Date()).getTime();
sethelplink('dashboard');"
>Dashboard</a>

What is sethelplink supposed to do? Or do you just want a
time-dependent string in the URL and sethelplink is unrelated?

By the way, the Math.round(...) looks superfluous. Just use new
Date().getTime() or a fraction of it, like new
Date().getTime().toString().slice(-9, -3) if seconds are good
enough, so the URL doesn't get needlessly long. But all this
does not work in the href value.

My first thought would be not to use the href attribute, but put
everything into onclick and do it in a JavaScript function.

Depending on circumstances, an alternative could be to modify
href through JavaScript already after the page is loaded.
Doesn't look as enticing though.

Thanks for the replies.. sethelplink() function is not related to what
we're doing but should be there.

Yeah I can remove the Math.round() function. Thanks for the
suggestion.

But here the problem is there is a target defined for the href. If
you see "target=icc", that is where the target page loads into. "icc"
is a frame. So How can I load the page into this icc in the Java
script function
