将变量传递给内部函数

Question

function getSsrBandAid(ssn,id) {    
   DWREngine._execute(_ajaxConfig._cfscriptLocation, null, 'getSsrBandAid', ssn, doQueryResults); //calling method in decRequest.cfc    
   function doQueryResults(t){  
     xmlT = loadXMLString(t);  
     alert(ssn);            
   }
}

Trying to pass ssn to doQueryResults() function.
I have tried to this doQueryResults(t,ssn) but it doesn't work.

Any help appreciated.

Thanks

Answer 1

ECMA-/Javascript has a static (lexical) scope. It also has the feature, that an "innerContext" closes over an "outerContext".

To make a long long story short, your doQueryResults() will copy the parent Scope (which is getSsrBandAid). That includes the Activation object which holds the arguments.

So if alert(ssn); is undefined, it is also undefined when calling getSsrBandAid() .
