I have a javascript function that contains an argument.
<a href="#" onclick="changeAvatar(0684839741);">Click here</a>
I need that argument to be a string because sometimes there will be Letters or a Leading 0 that I will need to preserve like in this example.
I checked to make sure that the argument that is passed in is a string with
x.constructor === String
But in my changeAvatar function, the argument comes through as no longer a string. Instead it is a number and removes the leading zero or breaks if it contains a letter.
How do I get the argument to retain it's type?

1Have you tried adding single quote marks (apostrophes) around your argument?jwheron– jwheron2011年12月21日 00:14:44 +00:00Commented Dec 21, 2011 at 0:14

You've typed it as a javascript number as this line of javascript evaluates it to a number:
changeAvatar(0684839741);
If you want it to be a string, you have to do it this way where you explicitly declare it as a string like:
changeAvatar('0684839741');
which means the whole line should be this:
<a href="#" onclick="changeAvatar('0684839741');">Click here</a>

Add single quotes:
<a href="#" onclick="changeAvatar('0684839741');">Click here</a>
