Question

i have this javascript var:

var mylist = '1,5,3,7,9,8,44,6';

I need to remove the 9, so that the final value is: 1,5,3,7,8,44,6

I usually do this server side with php (easy way). How can achieve this with javascript? A solution using jQuery would be even better.

considerations: it should work also if var is ‘99,9,96’ or ‘9’ or ‘99,9’ or ‘9,98’ …etc.

Answer 1

my_list = my_list.split(',').filter(function(e) { return e != 9}).join(',');

Later edit: to support array.filter in IE:

//This prototype is provided by the Mozilla foundation and
//is distributed under the MIT license.

if (!Array.prototype.filter)
{
  Array.prototype.filter = function(fun)
  {
    var len = this.length;
    if (typeof fun != "function")
      throw new TypeError();

    var res = new Array();
    var thisp = arguments[1];
    for (var i = 0; i < len; i++)
    {
      if (i in this)
      {
        var val = this[i]; // in case fun mutates this
        if (fun.call(thisp, val, i, this))
          res.push(val);
      }
    }

    return res;
  };
}
