Question

I am trying to set a javascript global var using jquery and dynamic variable names like this:

var home_phone_number // located outside of any functions
.
.
.
function setPhoneVars(phone){
// do stuff here to determine the correct prefix
thePrefix = 'home_phone_'
$(thePrefix + "number").val(phone.number);

}

When I do this, the value of home_phone_number is undefined.

But, when I set the phone number manually, like this:

home_phone_number = phone.number

the variable is set as expected.

Answer 1

Global variables are properties of the window object, so can be accessed as such:

window[thePrefix+'number'] = phone.number;
