In your condition use "==" not "="

To answer you question about finding a substring..

I will try:

if(variableInQuestion.indexOf("shoes")!=-1) { }

And two of your if conditions use = not == you probably want to fix that.

UPDATE:

Looking at your question again..

"Formal shoes" "Casual shoes"

Is it possible that you want an endsWith("shoes") method? If so: endsWith in JavaScript

I think you could use regular expressions:

this tests for shoes case insensitive. (match also "shoesprostore")

if (/shoes/i.test(ele.Department)) { }

this tests for the word shoes case insensitive. (match "Big Shoes" and "Small Shoes") (edit 4)

if (/\bshoes\b/i.test(ele.Department)) { }

edit:

this tests for the words shoe and shoes case insensitive.

if (/\bshoes?\b/i.test(ele.Department)) { }

\b : start and finish of a word

? : the previous character may or may not be present

i (after the sencond /) : case insensitive

look here for more http://www.w3schools.com/jsref/jsref_obj_regexp.asp

:)

edit 2:

corrected grammar inconsistencies thanks to my friend SandMan

edit 3:

maybe you could save the regex in global scope (before the $(document).ready(...) statement) using

var shoeTest = /shoes/i; then

if (shoeTest.test(...))

is ##if (/shoes/i.test(ele.Department))## working with firefox 3.6 too?
