## Why Don't You Have To Declare Variables In Javascript?

Jul 20, 2005

can anybody put forward a sensible argument javascript's behaviour of
creating a new global variable whenever I assign to a previously undeclared
variable. I can't beleive this is just for the sake of convenience (surely
we learned this much from basic).

here's my proposal: all "global" (document scope) variables must be declared
by 'var' outside a function block.

failing that, does anyone know any patterns or tricks I can use to make sure
I don't create a new global variable when I accidentally misspell a variable
name?

## Possible To Declare A Default Value In A Function?

Jan 28, 2009

How do i declare a default value in a function? I have a simple function

function color_input(id,token){
if (!empty(token)){
document.getElementById(id).style.backgroundColor = '#2A2A2A';
document.getElementById(id).style.color = '#DDC58C';

[Code]....

You will notice that the #2 parameter is missing in the html call. Sometimes i don't have it to send. in PHP i would just set the functions second param like token=''

function color_input(id,token=''){}

This is my jQuery ajax code for connecting to send-email jsp:
