xpages - prevent SSJS on page load in CSJS - xpages

Question

I have some SSJS within CSJS onclick event of a button. Is there any way to prevent this SSJS from executing during page load?
Thanks

This can be done by checking facesContext.getRenderResponse(). If it is true, the page is reloaded, otherwise it is false. The flag is not set correctly but gives you an easy way to check if the page is loaded or not.
Here is an example XPage:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:button value="Reload CSJS" id="buttonReloadCSJS">
<xp:eventHandler event="onclick" submit="true" refreshMode="complete">
<xp:this.script>
<![CDATA[#{javascript:
facesContext.getRenderResponse()?"alert('NotOnLoad');":"alert('OnLoad')";
}]]>
</xp:this.script>
</xp:eventHandler>
</xp:button>
</xp:view>
If you open the XPage and click the button, the page will be reloaded and you will have another CSJS code.
EDIT:
Here is another way to calculate code only if the button was partial refreshed:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:div id="refreshMe">
<xp:button value="Reload CSJS" id="buttonReloadCSJS">
<xp:eventHandler event="onclick" submit="true" refreshMode="partial" refreshId="refreshMe">
<xp:this.script>
<![CDATA[#{javascript:
var ajax = new com.ibm.xsp.ajax.AjaxUtil();
if( ajax.isAjaxPartialRefresh(facesContext) == true){
return "alert('Refreshed')";
}
}]]>
</xp:this.script>
</xp:eventHandler>
</xp:button>
</xp:div>
</xp:view>
