Do something with .each id of a string broken by ,

Question

Hello I have a var called numbers which is a string of number broken by a , I need to use each of these to do something with. Can anyone help me fill in the missing part:

var numbers = 1313,1314,1252,1244,1223,34,123,1,245;

(FOR Each number of numbers set AS numbersSingle)
     var numbersSingle = 1313;
    $(".notification").remove("#" + messageSingle);

I hope this makes sense, if anyone needs anymore information please let me know, thanks all!

each element has specific id hence no need to use class specifier, Simply remove the item by its id. — Braj, Jul 27 '15 at 09:21
do you want to split the variable on "," and get all the numbers? I din't understand what you want to convey by using the for each loop here. — Rajan Goswami, Jul 27 '15 at 09:23

You can do something like this

var numbers = ("1313,1314,1252,1244,1223,34,123,1,245").split(",");

for (var a = 0; a < numbers.length; a++) {
  $(".notification").remove("#"+numbers[a]);
}

array indexes are zero based, so `a = 0`. Also you don't need to wrap the string in brackets. – Rory McCrossan Jul 27 '15 at 09:22
yeah fixed that, thanks. I like to add bracket around string, it add more clarity for me i guess. – slashsharp Jul 27 '15 at 09:28

var numArray = numbers.split(',');

for (var x = 0; x < numArray.length; x ++) {
    console.log(numArray[x]);
}

Here is a JSFiddle - open the console to see output.

The bit you're missing is the split() function that converts a string to an array based on a separator.

You can use other loops on the array if you prefer - there's some more detail here.

Assuming the var is a string.

var numberArray = numbers.split(',') //This will return an array with earch element split by a comma.

iterate through the array using

numberArray.each(function(e){
  console.log(e); //do what ever you want for each value.
})

You don't need to loop here. You can amend the string to form a valid selector with each id separated by a string, eg: #1313,#1314... etc, and then remove them all in a single operation. Try this

var numbers = "1313,1314,1252,1244,1223,34,123,1,245";
$('.notification').remove('#' + numbers.replace(',', ',#'));

You can use split and $.each from jquery

 $(document).ready(function() {

    var numbers = "1313,1314,1252,1244,1223,34,123,1,245";
    var numbersArr = numbers.split(",");
     $.each(numbersArr,function(key, value) {
          console.log(value);
     });
   });

where value is each value from your numbers

ref split

ref $.each
