add the value to the array only if it is enclosed in quotation marks

Question

add the value to the array only if it is enclosed in quotation marks

Input array

var array = [
  'name',
  '"Mobile Number"',
  '"mobile1,mobile2"',
  'email2',
  'Address',
  'email21'
]

var matchkey = 'mobile1,mobile2'

res = res.map(function (value) {
if(value==matchkey){
return value+".string()"
}
else {
return value+".auto()"
}
            
        })

Current Output from above code

[
  'name.auto()',
  '"Mobile Number".auto()',
  '"mobile1,mobile2".auto()',
  'email2.auto()',
  'Address.auto()',
  'email21.auto()'
]

Expected Ouptput;

[
  'name',
  '"Mobile Number.auto()"',
  '"mobile1,mobile2.string()"',
  'email2.auto()',
  'Address.auto()',
  'email21.auto()'
]

Note: I don't wish to eliminate double quotes inside single quotes as they are necessary for future processing

Answer 1

Answer №1

The matchkey you provided is not found in the array.

String stored in array: '"mobile1,mobile2"'

MatchKey found: 'mobile1,mobile2'

To proceed, update your matchkey to:

var matchkey = '"mobile1,mobile2"'

It seems that your intended output is to have the name string without any function access. In that case, consider adding an else if statement as shown below:

if(value == matchkey){
    return value+".string()";
} else if(value == 'name') {
    return value;
} else {
    return value+".auto()";
}

Could it be this solution?

let data = [
  'name',
  '"Mobile Number"',
  '"mobile1,mobile2"',
  'email2',
  'Address',
  'email21'
]

let searchKey = '"mobile1,mobile2"'

const result = data.map(function(item) {
  return item == searchKey ? item.slice(0, -1) + ".string()\"" : 
    item.endsWith('"') ? item.slice(0, -1) + ".auto()" + '"' : item + ".auto()"
})
console.log(result)

To perform the substitution, you can utilize regular expressions (regex):

const output = elements.map((item) =>
  item.replace(/^("?)(.*?)("?)$/, function () {
    return `${
      arguments[1]
    }${arguments[2] + (arguments[2] === comparisonKey ? '.modify()' : '.alter()')}${arguments[3]}`;
  })
);

  })
);

Answer №4

If you make the switch from value==matchkey to value.includes(matchkey), you should see the desired result.

var items = [
  "username",
  '"Phone Number"',
  '"phone1,phone2"',
  "email3",
  "Location",
  "email31",
];

var matchkey = "phone1,phone2";

result = items.map(function (value) {
  if (value.includes(matchkey)) {
    return value + ".string()";
  } else {
    return value + ".auto()";
  }
});

console.log(result);

  } else {
    return value + ".auto()";
  }
