<p>Jpritcha: </p> <hr /> <div>__NOTOC__<br /> {{Global Header}}<br /> {{Global Announcement}}<br /> <br /> == Overview ==<br /> This article shows how items passed through a trigger can be queried from the script.<br /> <br /> == Details ==<br /> Lets assume we have already added a [[Site-Defined Trigger]] to call zMyScript and pass the Assignee value.<br /> <br /> '''Example:'''&lt;source lang=&quot;javascript&quot;&gt;POST_VALIDATE zMyScript(assignee) 111 FILTER(EVENT(&quot;UPDATE&quot;));&lt;/source&gt;Lets focus only on the zMyScript(assignee) portion.<br /> <br /> Three items of information regarding the assignee are passed from the trigger to the script.&lt;br&gt;<br /> &lt;nowiki&gt;[1]&lt;/nowiki&gt; is the original state value before editing began.&lt;br&gt;<br /> &lt;nowiki&gt;[2]&lt;/nowiki&gt; is the last known value when the trigger was initiated.&lt;br&gt;<br /> &lt;nowiki&gt;[3]&lt;/nowiki&gt; is the new value that is expected to be saved.&lt;br&gt;<br /> <br /> We can then query item &lt;nowiki&gt;[1]&lt;/nowiki&gt;, &lt;nowiki&gt;[2]&lt;/nowiki&gt;, or &lt;nowiki&gt;[3]&lt;/nowiki&gt; in our script as needed.<br /> <br /> '''Example:'''<br /> &lt;source lang=&quot;javascript&quot;&gt;cr::zMyScript(...){<br /> if( is_null( argv[3]){<br /> set_error( 1);<br /> set_return_data( &quot;Assignee needs to be filled.&quot;);<br /> };<br /> };&lt;/source&gt;</div>
