Jquery and Jslint - '$' was used before it was defined
I have some third party javascript im working with, I added some jquery code into it the javascript file. But it seems to fail on the above code when validating using Jslint
'$' was used before it was defined.
I can see at the top of the javascript file it states:
/*global alert: false, console: false, jQuery: false */
Im relatively new to Javascript, and JQuery, so any help would be welcome.
Answers:
Add these options to your comments:
/*jslint browser: true*/
/*global $, jQuery, alert*/
If you want to use variables provided by other scripts, then you need to say so:
/*global $ */
For JSLint In Netbeans IDE go to:
Tools - Options - Miscellaneous - JSLint tab - Text area under "Predefined (, separated)":
- add $;
- add your other project global variables, separating with comma.
Now JQuery variable $ is considered defined everywhere in code.
