Verifying Referral URL String & Cookie String with Javascript IF

Question

I am attempting to verify the referral URL and whether or not a cookie contains a certain string and then perform an action, however right now - my IF statement is always TRUE.

When I remove the ref1 section, and only keep getcookie, I believe the statement is false; although then my else if does not work

Nevertheless, I believe the construction of this If statement is missing something.

if (ref1.indexOf('ccov') || ref1.indexOf('top10') || ref1.indexOf('cenf') || ref1.indexOf('aip')||
 ref1.indexOf('constructioncoverage')|| 
ref1.indexOf('aginginplace')|| ref1.indexOf('seniorliving')|| ref1.indexOf('seniorlist') ||
 ((getcookie('track-page-1').indexOf('ccov')>-1) > -1) ||
 ((getcookie('track-page-1').indexOf('top10')>-1) > -1) ||
 ((getcookie('track-page-1').indexOf('cenf')>-1) > -1) ||
 ((getcookie('track-page-1').indexOf('aip')>-1) > -1)) {

Answer 1

It's tricky to debug this code as a sample of the value of ref1 is not provided. However, I can give some advice on where to go with this.

The indexOf method returns either the index of the substring/element provided, or -1 if not present. Be aware that Boolean(-1) returns true.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/indexOf

document.referrer is a string, so you should probably make use of the includes method on string. This properly yields true when the substring is present, and false when it is not.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/includes

Try replacing the indexOf methods on ref1 with includes like so:

if (ref1.includes('ccov') || ref1.includes('top10') || ref1.includes('cenf') || ref1.includes('aip') ||
        ref1.includes('constructioncoverage') ||
        ref1.includes('aginginplace') || ref1.includes('seniorliving') || ref1.includes('seniorlist') ||
        ((getcookie('track-page-1').indexOf('ccov') > -1) > -1) ||
        ((getcookie('track-page-1').indexOf('top10') > -1) > -1) ||
        ((getcookie('track-page-1').indexOf('cenf') > -1) > -1) ||
        ((getcookie('track-page-1').indexOf('aip') > -1) > -1)) {
    }
