RegEx matching problem with array.indexOf() in Google Scripts-CodePudding

I can't get IndexOf to match correctly in GAS

I've tested out my regular expression here: https://regex101.com/r/0cK6xQ/1

As soon as there is a space inside the string, indexOf() will not match. I even tried setting the regex as let contactRegExp = /(contact 1 Type)/i ; , which should be a direct match for the 2nd element in the sample array and it bombs out.

function setContactTypes(){  

 //Find all contact Type columns
 let contactRegExp = /(contact [\d]* Type)/i ;

 var headerIndexList = ['dummy1','contact 1 Type','dummy2','contact 2 Type'];

 var hitArray = [];
 var i = -1;
 while ((i = headerIndexList.indexOf(contactRegExp,(i 1))) != -1){
     hitArray.push(i);
  }
}

hitArray should return [1,3]

I'm thinking it has something to do with an Array vs a string, but for the life of me can't figure it out.

CodePudding user response：

Unfortunately, Array.prototype.indexOf() cannot use the regex. So in your situation, in order to achieve your goal, how about the following modified script?

Modified script:

function setContactTypes(){  
 let contactRegExp = /(contact [\d]* Type)/i ;
 var headerIndexList = ['dummy1','contact 1 Type','dummy2','contact 2 Type'];
 var hitArray = headerIndexList.reduce((ar, e, i) => {
   if (contactRegExp.test(e)) ar.push(i);
   return ar;
  }, []);
  console.log(hitArray) // When your "headerIndexList" is used, [1, 3] is returned.
}

Testing:

Show code snippet

let contactRegExp = /(contact [\d]* Type)/i ;
var headerIndexList = ['dummy1','contact 1 Type','dummy2','contact 2 Type'];
var hitArray = headerIndexList.reduce((ar, e, i) => {
  if (contactRegExp.test(e)) ar.push(i);
  return ar;
}, []);
console.log(hitArray)

For example, the following script is useful for your situation?

let contactRegExp = /(contact [\d]* Type)/i;
var headerIndexList = ['dummy1', 'contact 1 Type', 'dummy2', 'contact 2 Type'];
var hitArray = [];
for (var i = 0; i < headerIndexList.length; i  ) {
  if (contactRegExp.test(headerIndexList[i])) {
    hitArray.push(i);
  }
}
console.log(hitArray)
