Using the variable “name” doesn't work with a JS object

Question

The behaviour can be seen in this little snippet (execute it as a global script):

var name = {};
name.FirstName = \'Tom\';
alert(name.FirstName);
         


        

Answer 1

window.name has a special purpose, and is supposed to be a string. Chrome seems to explicitly cast it to a string, so var name = {}; actually ends up giving the global variable name (i.e. window.name) a value of "[object Object]". Since it's a primitive, properties (name.FirstName) won't "stick."

To get around this issue, don't use name as a global variable.
