Re: [PHP] A two flavored post

strange; i missed that when i put it together; my bad, it was late.
here is a revision that works.

<html>
<head>
<script type="text/javascript">
window.onload = function() {
var someLink = document.getElementById('someLink');
someLink.href += "&anotherVar=8";
alert(document.getElementById('someLink').href);
}
</script>
</head>
<body>
<a id="someLink" href=" http://somesite.com?a=5";>
click here
</a>
</body>
</html>

the problem was the local variable was being assigned the value of the
attribute, not the reference
to the tag in the dom. i have now set it to be a reference to the variable
in the dom.

Hi gang:

I asked this question on the javascript list, but for some reason
it's taking forever to post there. So, I figured that I would ask
here as well.

I'm currently sending data (the value of s) to another script via the
html statement:

<a href="img.php?s=<?php echo($value);?>">Click here</a>

However, I need to add another variable, namely a javascript
variable, to the GET string.

How can I send both a php and a javascript variable together at the same
time?


the question is when is the variable you want to append available to
the javascript.
as soon as you get the variable in the javascript the next thing you
can do is append
it to the value of the href attribute of the <a> tag.

<html>
<head>
<script type="text/javascript">
window.onload = function() {
var someLinkHref = document.getElementById
('someLink').href;
someLinkHref += "&anotherVar=8";
alert(someLinkHref);
}
</script>
</head>
<body>
<a id="someLink" href="
<http://somesite.com?a=5>http://somesite.com?a=5";>
click here
</a>
</body>
</html>

if you want to use the onclick event handler as rob suggested, you
could stash the variable in the Window global object, then reference
it in the implementation of the onclick function (though i still
have mixed feelings about that approach [the Window object part that
is]).

Your example worked very well to provide an alert showing exactly
what I needed to be in the href string. However, it didn't work to
actually alter the actual link href string -- even when I commented
out the alert. IOW, it remained:

<http://somesite.com?a=5>http://somesite.com?a=5

instead of:

<http://somesite.com?a=5>http://somesite.com?a=5&anotherVar=8

I like the idea of keeping the code unobtrusive and working as it did
-- I just need it to work as a link.

Any ideas? This is so close.

Cheers,

tedd
