Replace string in javascript array

Question

I have an array in javascript. This array has strings that contains commas (","). I want all commas to be removed from this array. Can this be done?

Answer 1

Yes.

for(var i=0; i < arr.length; i++) {  arr[i] = arr[i].replace(/,/g, ''); } 

Answer 2

The best way nowadays is to use the map() function in this way:

var resultArr = arr.map(function(x){return x.replace(/,/g, '');}); 

this is ECMA-262 standard. If you nee it for earlier version you can add this piece of code in your project:

if (!Array.prototype.map) {     Array.prototype.map = function(fun /*, thisp*/)     {         var len = this.length;         if (typeof fun != "function")           throw new TypeError();          var res = new Array(len);         var thisp = arguments[1];         for (var i = 0; i < len; i++)         {             if (i in this)                 res[i] = fun.call(thisp, this[i], i, this);         }          return res;     }; }
