Print / display a JavaScript variable’s name instead of it’s value

by

You can put the variables in an object then easily print them this way: http://jsfiddle.net/5MVde/7/

See fiddle for everything, this is the JavaScript…

var x = {
    foo: 5,
    bar: 6,
    foobar: function (){
        var that=this;
        return that.foo+that.bar
    }
};

var myDiv = document.getElementById("results");

myDiv.innerHTML='Variable Names...';
for(var variable in x)
{
    //alert(variable);
    myDiv.innerHTML+='<br>'+variable;
}

myDiv.innerHTML+='<br><br>And their values...';
myDiv.innerHTML+='<br>'+x.foo+'<br>'+x.bar+'<br>'+x.foobar();

The JavaScript for…in statement loops through the properties of an object.

Another variation (thanks @elclanrs) if you don’t want foobar to be a function: http://jsfiddle.net/fQ5hE/2/
