18.10 ADD_ONLOAD_CODE Procedure

This procedure adds a javascript code snippet to the HTML output which is executed by the onload event. If an entry with the same key exists it is ignored. If p_key is NULL the snippet is always added.

Syntax

APEX_JAVASCRIPT.ADD_ONLOAD_CODE (
    p_code           IN VARCHAR2,
    p_key            IN VARCHAR2 DEFAULT NULL);

Parameters

Table 18-9 ADD_ONLOAD_CODE Parameters

Parameter	Description
`p_code`	Javascript code snippet to be executed 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' );
