How Can I Create These Variables In A For Loop?

What about if I had something like this where a for loop creates all the variables for you...rather than having to write them out on individual lines like so:

for(i = 0; i < myForm.elements.length; i++) {
tempControl = myForm[i];
var e = tempControl.name;
var [e] = document.myForm[e].value;
}

As oppose too:

bodyChooseColour = document.myForm.bodyChooseColour.value;
bodyChooseFont = document.myForm.bodyChooseFont.value;
bodyChooseFontSize = document.myForm.bodyChooseFontSize.value;
bodyChooseFontColour = document.myForm.bodyChooseFontColour.value;

etc...

However, the for loop does not work...Firefox JavaScript console reports 'Missing variable name' pointing to the 'e'.
