Trying to hide a panel if a return value does not exist

  • Category: Dojo and Client Side JavaScript

I have an XPage Custom Control with multiple panels and repeats.  Everything is working with one exception.  I want to hide / show a panel only when there is information to display. 
As you can see below, the Locator Info label.  It is in a Panel along with the computedField4.  Computed Field4 gets populated from data in a previous repeat.  I do a lookup with a value from the previous repeat and pull data from another database. 
 
I want to hide the Locator Info panel if no values were found that would populate computedField4.  I put a formula in the Visible section of the Panel that looks for a scoped variable  which I set when I do the lookup for computedField4.  If I find data I set the scorped variable to 1 if not I set it to 0.  It is not showing the hidden panel when it executes.  Below the screen shot is the pertinent code for the panel.
 
Any thoughts would be appreciated!

Re: Trying to hide a panel if a return value does not exist
It looks like you test if the viewScope variable exists. Check the value of the variable with something like
 
<xp:this.rendered><![CDATA[#{javascript:if (viewScope.xx==null) {
    return false;}
else {
if (viewScope.xx == "1") {
    return true;
}
}}]]></xp:this.rendered>

Hi,
 
in your posted code the viewScope will never get filled and always be empty. The code won't be executed, because the rendered property is always false.

Sven,
I thought that might be the case, so how do I get the code to execute but only display the text if a value was found?

Re: Trying to hide a panel if a return value does not exist
Hi,
 
you could try to change the rendered property of the components to this:
 
<xp:this.rendered><![CDATA[#{javascript:var ok:boolean = true;
try{
    var sRepeat:com.ibm.xsp.component.xp.XspDataIterator = getComponent("locatorRowData");
    if( sRepeat.getValue() == null )
        ok = false;
    if( sRepeat.getRowCount() == 0 )
        ok = false;
}catch(e){}
       
return ok;}]]></xp:this.rendered>
 
Hope this helps
Sven
