jsMath javascript suite is very useful for displaying math
On normal pages produced with this script in mind it is enough to add <script type="text/javascript" src="jsMath/jsMath.js">
How one can load some js on SilverStripe pages?

Thank you in advance. Victor

So, what is the way to add external javascript to CustomPage?

Thank you in advance

Victor

how about

Requirements::javascript("filejs");

Well, I know this (and it should be enclosed into

public function init()
{

}

However it does not work in some particular case:

Compare

http://weyl.math.toronto.edu:8888/devsite/x.html

which shows properly parsed mathematical expression

with

http://weyl.math.toronto.edu:8888/devsite/test/?stage=Live

Hi Victor

On the page where it works you have the following javascript statement: jsMath.Process();
Whereas on the SilverStripe site it's completely lacking...
You should probably add

Requirements::customScript('jsMath.Process();');

to your init method.
Some other file seems to be missing on the SilverStripe site as well. I get the following error in firebug:
uncaught exception: jsMath can't load the file 'http://weyl.math.toronto.edu:8888/devsite/test/jsMath-fallback-symbols.js' Error status: 404

Well, it did not work this way but your post suggested me a different solution: instead of paste htm source in (html) in Content allowing to TinyMCE to handicap it, I created new HTMLText field and pasted html snippet with reference to javascript there

http://weyl.math.toronto.edu:8888/devsite/test/?stage=Live

PS Still I left reference to jsMath in .php, I suspect it is needed

Thanks! Victor

how about

 LeftAndMain::require_javascript('mysite/javascript/initGoogleMaps.js')
