append <script> to all pages but these

Question

Thank you very much in advance for any help on this one.

I am appending a tracking script to a few pages - code below. Now we need to append the script to all pages except one. I am lost on how to do this.

How can you append a script to all pages but /index3.html?

$(document).ready(function(){
    var identifier = window.location.pathname;
    switch(identifier)
    {
        case: 'index.html';
            $('<script type="text/javascript" src="http://cti.w55c.net/ct/ct-f20dc88483814e189d5436461ea953ae.js"></' + 'script>').appendTo(document.body);
        break;

        case: 'About.aspx';
            $('<script>Tracking Pixel XYZ</' + 'script>').appendTo(document.body);
            break;
    }

});

Again thank you.

You can do it like this:

JQUERY

var identifier = window.location.pathname;
if (identifier.indexOf("index3.html")  >= 0) {
  var script = document.createElement( 'script' );
  var url = 'http://cti.w55c.net/ct/ct-f20dc88483814e189d5436461ea953ae.js';
  script.type = 'text/javascript';
  script.src = url;
  $("#someElement").append( script );
}

This will verify if the current location is index3.html, if not, create the script tag and append it to your element.

The comparison by greater ^> and equal ⁼ makes sure that if value is found at position 0, it will match!

Javascript indexOf() method returns -1 if the value to search for never occurs.

EDITED

To check for two files...

if ( (identifier.indexOf("index3.html") >= 0)
  || (identifier.indexOf("index4.html") >= 0)) { ... }

Answer 2

var winloc = window.location.pathname;
var isindex3 = /index3$/i.test(winloc);
if(ishtml === true){
//add script to pages that are index3.html
}else{
//if you want add script to pages that are not index3.html
}

If window.location ends with html execute javascript
