Trying to convert comma-separated string to array w/ quotes around each value in js:
var ipd = 'field1,field2';
console.log('Img Pad string: ' + ipd); // field1,field2
var ipdarray = new Array();
ipdarray = ipd.split(',');
console.log('Img Pad array split: ' + typeof ipdarray); // object
console.log('Img Pad array: ' + ipdarray); // field1,field2I want the array to be: ["field1","field2"]
Tried to follow this: Convert comma separated string to array but it's not converting to an array.
It is being converted to an array, but when you output the string (in console.log), the array is being coerced back into that string syntax because of the + operator (acting as a concatenator).
Here is a more isolated example of what is happening:
var string = 'field1,field2';
var arr = string.split(',');
console.log(Array.isArray(arr));
console.log(arr.length);
//When using the +, it will coerce into a string
console.log('Coerce to string ' + arr);
//When passing the array as an argument, it will stay an array
console.log('Stays and array', arr);In order to preserve the array literal syntax, you'll need to JSON.stringify the array before outputting it if you want to use the + operator, or you can just output the array as a separate argument to console.log
JSON.stringify(ipdarray);
See it in action:
var ipd = 'field1,field2';
console.log('Img Pad string: ' + ipd); // field1,field2
var ipdarray = new Array();
ipdarray = ipd.split(',');
console.log('Img Pad array split: ' + typeof ipdarray); // object
console.log('Img Pad array: ' + JSON.stringify(ipdarray)); // ["field1","field2"]
// OR
console.log('Img Pad array: ', ipdarray); // ["field1","field2"]Also, arrays are "object"s, but there are other ways to determine if that "object" is an instance of an array:
var arr = [];
console.log(typeof arr);
console.log(arr instanceof Array)
console.log(Array.isArray(arr));
JSON.stringify return a string, despite that looks like an array of string, it is not, I thought that the OP wanted an array of string surrounded by ", like ['"field1"','"field2"']Given input string you can use String.prototype.match() with RegExp /[^,]+/g to match one or more characters which are not comma ,
var ipd = 'field1,field2';
var ipdarray = ipd.match(/[^,]+/g);
Note that + operator converts array to string at
console.log('Img Pad array: ' + ipdarray); // field1,field2
use comma , operator at console.log() call
console.log('Img Pad array: ', ipdarray); // field1,field2
var a = "field1,field2"
var b = a.split(',');
var c = b.map(function (v) {
return '"' + v + '"';
})
console.log(c);
console.log(c[0]);
console.log(c[1]);
console.log('Img Pad array: ', ipdarray)?
