Check for null, undefined, or blank variables in JavaScript
/**
Test for "value is null or undefined" is

if ( some_variable == null ){
// some_variable is either null or undefined
}
// So these two lines are equivalent:
if ( typeof(some_variable) !== "undefined" && some_variable !== null ) {}
if ( some_variable != null ) {}
