How can one check a url if it contains a specific word, but also

  • 0

How can one check a url if it contains a specific word, but also check to see if it doesn’t contain a word? Its better if I try and display an example:

Do something if the word ‘pan‘ is in the URL, however do NOT do anything when the word ‘panini‘ is in the url:

if (/pan/.test(self.location.href) && (/panini/.test(self.location.href) == null)  {...}

The above first part works fine, but with the second panini part added it of course will not work, anyone have any ideas?

    test returns a bool, so just use the ! operator:

    if (/pan/.test(self.location.href) && !(/panini/.test(self.location.href))  {...}

    This could be simplified to use indexOf (should be faster):

    if (self.location.href.indexOf("pan") > -1 && self.location.href.indexOf("panini") == -1)
{...}

    Additionally, a regex testing for a word can use a word boundary, \b:

    /\bpan\b/.test(self.location.href)
//Will match "pan", "pan and food", but not "panini"
