Hello,

We would like to pass the file name found within the URL into a Javascript Variable.

For example if the URL is:

http://www.abc.com/folder/file-something.aspx
Or
http://www.abc.com/folder/folder/file-something.aspx

Then
s.prop5 = 'file-something';

The tricky part is that we need to also include an if statment to populate a default value if the home page is loaded in the URL.

For example if the URL is

http://www.abc.com

Then s.prop5 = 'home';

Thanks :)

Use :


var s.prop5 = 'home';
var start = location.pathname.lastIndexOf("/");
if(start>0) {
   s.prop5 = location.pathname.substr(start+1);
}

Thanks that has removed the javascript error, but it is passing through the file extension as well ".html" we are hoping to truncate this from the passed variable. As per our example above.

Thanks

Or :
var end = location.pathname.lastIndexOf(".")
s.prop5 = 'home';
var start = location.pathname.lastIndexOf("/");
var end = location.pathname.lastIndexOf(".");
if(start>0) {
   s.prop5 = location.pathname.substring(start+1, end);
}

Open in new window

You're welcome my friend! Thanks for the points!
Be careful with the first proposition (accepted solution) if your filename have more than one dot in it : my.file.name.html will return << my >>
