How To Insert JavaScript Into Modules/Blocks

General Joined: Mar 22, 2003 Posts: 5233 Location: USA

This question has been asked and answered more times than I can recall. There is a PHP built in way to do this that is very simple and fool-proof.

First I will show you an example and then explain it.

Code:

$someVarName = <<<_JSCODE_
<script>alert('Hello World');</script>
_JSCODE_;

echo $someVarName;

That's it! You simply insert your JavaScript code as you use it in your HTML document and drop it in. You do not have to escape any quotes or anything special. If it works in native HTML, it should work here.

Now for a caveat. You can use PHP variables in the code WITHOUT using the <? ?> tags. Here would be an example of that.

Code:

$messageText = 'Hello World';

$someVarName = <<<_JSCODE_
<script>alert('$messageText');</script>
_JSCODE_;

echo $someVarName;

Now, if you were using this in a block, you need to assign all content to the $content variable. You could do this in a separate line of code, like this

Code:

$messageText = 'Hello World';

$someVarName = <<<_JSCODE_
<script>alert('$messageText');</script>
_JSCODE_;

$content = $someVarName;

or just assign the block to $content instead of $someVarName like this.

Code:

$messageText = 'Hello World';

$content = <<<_JSCODE_
<script>alert('$messageText');</script>
_JSCODE_;

There is only 1 very important syntactical rule for usage. In my example _JSCODE_ is analogous to a BLOCK TAG. These tags can be named whatever you want, as can the $someVarName. However, the ending block tag MUST be left aligned AND there can be no character EXCEPT a carriage return after either of the block tags.

Feed a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.

I have provide examples for all cases. Even as recently as yesterday that answers your EXACT question. I have provided you your answer already.

I just had to grab that line, refrain from taking this to court for now as my lawyer went on a strike.

Author unknown on the quote. Don't you just love it when you supply the answers and still get blasted? I want a raise! I deserve at least a case of Pepsi a month.

Something in that general direction may be coming up soon, now, you do have a point on what transpired in this post, not the first time i see it though, surely won't be the last.

Only in a perfect world, where everybody is fortunately enough to live near water where fish can survive in this wonderfull polluted world, could the following be believable:

We just may have to create a separate forum where we can lavish praise and kudos on the nukecops staff! Great job guys! Your help may often go uncommented but definitely not unappreciated. Very Happy

Just had to register and thank Raven, I've been trying to get some javascript to work in a block for a week now, took a lot of trila and error but finally got it done thanks to his tips.
