How do i pass value to a callback function

[Ravish Shetty]

Hello all,

Is there a way to pass value to the callback function when we use GlideAjax.

function onChange (){
var temp = '123';

var x = new GlideAjax ('ABC');
x.addParam ('sysparm_name','123');
x.getXML(callBack,temp);
}

function callBack (response,temp){
alert(temp);
}

Here i want to pass the value of variable temp to the callback function without declaring it as a global variable.

not really as familiar with ajax as I should be but have y ou tried this...

in the function put in return temp

now when you call it.. call it like this...

alert(function callBack (response,temp));

Hello Doug,

If possible, can you show it in the form of code on exactly how this will work?

Hello Ravio,

You can do it   with a closure:

function onChange(){

         var temp = '123';

         var x = new GlideAjax('ABC');

         x.addParam ('sysparm_name', '123');

         x.getXML( function (response) { callback (response, temp); });

}



function callBack (response, temp){

         alert(temp);

}
