Question

i feel like im trying to do something super simple, but just being stupid about it.

all i want to do is see if a variable has been set previously, and if it has NOT, set it with a default value….here is a sample:

if(!embed_BackgroundColor) {     var embed_BackgroundColor;     embed_BackgroundColor = '#F4F4F4'; } 

so, once you stop laughing at my code….WHY is it overwriting the variable no matter what?

please save my nerves;)

Answer 1

if (typeof variable === 'undefined') {     // variable is undefined     // eg:     // var variable = 'someValue'; }
