Passing Field Value to setDefinitionExpression of another feature.

[HushamHassan]

how to pass field value on click  events to setDefinitionExpression for another feature class.

I tried this one but its not working. I appreciate any Help.

                fld="SiteID";
               featureLayer.on("Click", function(events){
                 var testval=events.graphic.attributes[fld];
                 
                   featureLayer2.setDefinitionExpression("SiteID = 'testval'"); 
                     map.addLayer(featureLayer2);
               });‍‍‍‍‍‍‍

Husham,

it would be:

featureLayer2.setDefinitionExpression("SiteID = '" + testval + "'");

Thank you.  Yes  your solution worked perfect as mine.

featureLayer2.setDefinitionExpression('siteID = ' + testval);
