/**
|
|
|
14 |
* TClientScript class
|
|
|
15 |
*
|
|
|
16 |
* Allows importing of Prado Client Scripts from template via the
|
|
|
17 |
* {@link setPradoScripts PradoScripts} property. Multiple Prado
|
|
|
18 |
* client-scripts can be specified using comma delimited string of the
|
|
|
19 |
* javascript library to include on the page. For example,
|
|
|
20 |
*
|
|
|
21 |
* <code>
|
|
|
22 |
* <com:TClientScript PradoScripts="effects, rico" />
|
|
|
23 |
* </code>
|
|
|
24 |
*
|
|
|
25 |
* Custom javascript files can be register using the {@link setScriptUrl ScriptUrl}
|
|
|
26 |
* property.
|
|
|
27 |
* <code>
|
|
|
28 |
* <com:TClientScript ScriptUrl=<%~ test.js %> />
|
|
|
29 |
* </code>
|
|
|
30 |
*
|
|
|
31 |
* Contents within TClientScript will be treated as javascript code and will be
|
|
|
32 |
* rendered in place.
