How to use model int array variable in javascript MVC 4

Question

Model

public int[] mobileid{get;set;}

Script

var k;
for(var i=0;i<3;i++)
{
  [email protected][i];
  alert(k);
}

This method not working,How to assign int array variable to Javascript var. I already use below method:

var k=[];
[email protected](json.Encode(model.mobileid));//not work

var k = @Html.Raw(Json.Encode(Model.year)) will work fine (I assume you just have some typos (capital H, J and M) — user3559349

var k = @Html.Raw(Json.Encode(Model.year)); End of semicolon (;) showing syntax error — Mano Johnbritto

I now see from your acceptance of the answer (an awful way to solve your problem) that the model was null. You just need to check for null first - if (k) { for(var i=0;i<3;i++) { var x = k[i]; } } — user3559349

You can convert your Model.mobileid to a string with a separator of your choice and convert it to a javascript array:

<script>
    var k = "@(Model.mobileid == null ? string.Empty : string.Join(",", Model.mobileid))";
    alert(k);
    k = k.split(",");
    k // k is an array at this point
</script>

Its work good,But one issue,if(a==b) { var k = "@(string.Join(",", Model.mobileid))";//Now my mobileid is null, alert(k);} if condition is false,but it goes to if block,then show the null reference exception error.

updated my code. You can as well check the value of k after the first line before further operations.
