How to obtain the name of a Javascript variable

[Jochen Neyens]

Is there a function that can be used to get the name of a Javascript variable? Look at the example below. Is there a function like "GetVarName"? alert(GetVarName(tt)) sould alert the text "myText" ...

var myText = "lorem";

function test(tt) {
    alert(GetVarName(tt));
}

test(tt);
