Subject AW: [Tobago] Javascript reload after Ajax Request.
Date Mon, 14 Jun 2010 13:08:44 GMT
Hi Volker,

I've tried to load a js file with Tobago.ScriptLoader, but i got the message "myFunction is
not defined". Then i've tried to call the function dirctly by letting the array empty, but
the function was called for just a once at time. What am I Doing Wrong?


<tc:out escape="false" value="<script type=\"text/javascript\">new Tobago.ScriptLoader(['/MyApp/myScript.js'],
'myFunction();');</script>" />
<tc:out escape="false" value="<script type=\"text/javascript\">new Tobago.ScriptLoader([],
'initFunctionOnLoad();');</script>" />

in tobago 1.0.x is no support for tc:script during ajaxReload :-(
It is planned for 1.5, but, afaik, not implemented yet.

You can solve this in 1.0.x by using a tc:out with script content
inside the ajax reloaded panel.

eg. replace a
<tc:script file="scripts/myFunctions.js" onload="jsFunction()" />
with a
<tc:out escape="false"
          value="<script type=\"text/javascript\">new
'jsFunction();');</script>" />

The Tobago.ScriptLoader is the javascript function which is used by
tobago internally to handle component reinitializing after (re)load.
It takes a array of urls to load, if not already loaded, and a
javascript to execute after files are loaded.
If you look into the generated html source you can find some of this scripts.

You can let the array empty if the script files are already loaded via

Note: you must calculate those tc:outs into the layout constraints.
