Question

I have to the following function that I would like to modify so that it only binds the click event to all href’s that = /ShoppingCart.asp?ProductCode=”whatever” (whatever = whatever is in there”) but not if it is specifically /ShoppingCart.asp?ProductCode=”GFT”. It must also check or convert a gft or Gft to upper case to check for those as well. So basically it has to check for any variation of the case of GFT.
If it finds a “GFT” do not bind the click event.

function sacsoftaddtocart() {
    if (location.pathname == "/SearchResults.asp" || location.pathname == "/Articles.asp" || location.pathname.indexOf("-s/") != -1 || location.pathname.indexOf("_s/") != -1) {
        $("a[href^='/ShoppingCart.asp?ProductCode']").click(function () {
            var href = $(this).attr('href');
            addToCart3(href);
            return false;
        });
    }
}

You can do it using .toUpperCase() and .filter(), like this:

function sacsoftaddtocart (){
  if (location.pathname == "/SearchResults.asp" || location.pathname == "/Articles.asp" || location.pathname.indexOf("-s/") != -1 || location.pathname.indexOf("_s/") != -1) {
    $("a[href^='/ShoppingCart.asp?ProductCode']").filter(function() {
       return this.href.length - this.href.toUpperCase().indexOf('PRODUCTCODE=GFT') != 15;
    }).click(function () {
      var href = $(this).attr('href');
      addToCart3(href);
      return false;
    });
  }
}

You cant test it in a demo here. The this.href.length - matchPosition == 15 is checking that the ProductCode=GFT is both matched and there’s nothing after the “GFT”, so a product code like “GFT5” won’t match.
