How to Check Your jQuery Application on JSLint

JSLint is a browser application developed by Mr Douglas Crockford as JavaScript code quality test tool.

---

Let's get right on it
This is the error shown if we didn't declare the global variable option.

Undeclared '$'.

The list of options can be found on the bottom of the JSLint's user interface.

Find the Global variables... part, then type $.

Test your jQuery coding once more...
Fix some things...
repeat...

...And have yourself a neat progrum

External script
This option is also useful for declaring a (custom) global variable from your own (custom) external script, which is not "there" on that particular application-depended-on-that-external-script you check.

---

Intended for browser
Remember to tick the a browser option if your script uses the document object keyword.

Window, console, and others
There are few object keywords which aren't "included" in JSLint, like:

• window
• console
• And maybe others...

Include those keywords in the Global variables..., and bam!

BAM!
