javascript - how to add/include js file in xbl? -

i've read around , found techniques add js file inside xbl, techniques don't work. tried declare tag: <'script src='test.js''> , <'script src='chrome://content/test.js '>, none worked.

the method inside test class function caller() { alert("call succeeded"); }.

is there correct , simple way include js file inside xbl, calling functions file works if function written inside xbl.

here's more details: http://www.w3.org/tr/xbl-primer/#scripts you're doing seems fine, here's example they're giving:

<xbl xmlns="http://www.w3.org/ns/xbl">   <script src="example.js"/> 

note xmlns there, that's default namespace. if have defined as: xmlns:xbl="http://www.w3.org/ns/xbl" have use

<xbl:script src="example.js" /> 

try that, never tried myself namespace thing common pitfall.

edit: i'm afraid might not possible. xbl 2.0 spec, , gecko doesn't seem supporting yet, , in xbl 1.0 script tag not exist:

http://groups.google.com/group/mozilla.dev.tech.xbl/msg/d7d4f279ebdad65f?pli=1 mentioning here development should full swing.

here's link pointing to: https://wiki.mozilla.org/xbl2 seems hasn't been updated since 2009, it's hard tell if going implemented.

and here's xbl 1.0 reference can see script tag not exist: https://developer.mozilla.org/en/xbl/xbl_1.0_reference

but offer possible alternative - use modules, , in constructor this:

<constructor>     components.utils.import("resource://yourextension/config.js"); 

for more on modules: https://developer.mozilla.org/en/javascript_code_modules , example: https://developer.mozilla.org/en/javascript_code_modules/using you'd need register modules folder put test.js in it, follow instructions how "export" functions/variables it. can import javascript, xul or xbl file.
