Question about php/javascript

[Patrick3002]

Hi, im going to show you an example of what i want to do, then try ang explain it.

 

I have a page http://domain.com/run.php which when i go there i get a submit link, thats all. I have another page, http://domain.com/vote.php. When i click that submit link from /run.php i want it to perform the javascript func on /vote.php:

<a href="javascript:vote( 'right' );" border="0">[sUBMIT]</a>

When that is clicked on run.php:

function vote(side) {
document.getElementById("side_voting_on").value=side;


var v = false;
for (i=0; i<a.length; i++) {
	if (a[i]==2617072) {
		v = true;
		break;
	}
}
if (!v) {
	document.getElementById('vote_form').submit();
}
else {

	location.href = "/vote.php";

}
}

 

When the submit link on run.php is clicked, i want the javascript func on vote.php to run.

 

If anyone can help me out with this, that'd be greatly appreciated!

if(isset($_REQUEST['submit'])) {

echo "<a href="javascript:vote( 'right' );" border="0">[sUBMIT]</a>";

}

How does that in anyway link from run.php to vote.php? Read the post again. I need to run the javascript on vote.php FROM run.php by clicking a link or whatever else is easiest. Thanks for the try though!

im new to php but couldnt you do something like

putting the function on func.php

include("func.php"); on both pages then use

onsubmit(<?php ... ?>)

You might look into ajax.

Often there is an easier solution to a problem if you just rethink the problem.

Why does the javascript have to be on vote.php? Why don't you make it a function and run it on any page you want? Why are you making it more difficult than just regular javascript?

Thanks, i might look into that. I'm making it that way because thats the way it has to be for the situation at hand.

As I was saying, it doesn't always have to be as hard as it seems.

But okay. Check out mootools.net for a cool ajax library

As was said by jesirose, ajax is a great option, assuming the browser supports it.  Another option, if a redirect to vote.php is possible, you can use javascript to check and see that the referrer is run.php.

 

This isn't foolproof, however, as some browsers block that information or allow it to be spoofed.

 

Please also try to have an option available for those surfers who do not have javascript enabled.
