is NULL the snippet is always added.
Syntax
APEX_JAVASCRIPT.ADD_ONLOAD_CODE (
p_code IN VARCHAR2,
p_key IN VARCHAR2 DEFAULT NULL )
Parameters
Parameter | Description |
---|---|
p_code
|
JavaScript code snippet to execute during the onload event. |
p_key
|
Any name to identify the specified code snippet. If specified, the code snippet is added if there has been no other call with the same p_key . If p_key is NULL the code snippet is always added.

Example
Adds the JavaScript call initMySuperWidget(
to the onload buffer. If the plug-in is used multiple times on the page and the add_onload_code
is called multiple times, it is added once to the HTML output because all calls have the same value for p_key
.
apex_javascript.add_onload_code (
p_code => 'initMySuperWidget();',
p_key => 'my_super_widget' );
