Checking a Boolean Value In JavaScript

[Steve Dyke]

Using the following code it fires the load whether projectFlag equals true or false.

function updatedrawingliststatus(){
		alert(projectFlag);
		if(new Boolean(projectFlag)){
			$("#rmataskmanager").empty();
			$("#rmataskmanager").load("/DrawingPDMW1/AccessRMATaskManagementServlet",{p1:diindex},getUDLSResults);
		}
		else{
			alert("There is no Project in Resource Management for this Job Number."+"\r\n"+"Contact a Manager to have one added!");
		}
	}

Well what you are doing looks to be the correct way to do it, but it is not.

new Boolean("any string") produces true for any string. That means a string that contains false will be evaluated as true

Your only real option here is to do

if(projectFlag=== 'true'){

Is there any way to pass a boolean value from the servlet back to my JSP using AJAX(jQuery) call?

[Eric Pascarello]

if you eval / new Function it

That will cause more problems than just checking for the string.
