Question

Model.Choices is a string array in my MVC3 view. My question is, how can I get a JavaScript string array from it? If you do something like:

var choices="@Model.Choices";
alert(choices);
alert(choices[1]);

The message will be “choice1choice2choice3choice4” and “undefined”

What is the syntax I need to have to have choices turn into a string array in JavaScript? For example:

alert(choices[0]);
alert(choices[1]);

Should output “choice1”, and “choice2”.

Answer 1

var choices = [ '@Html.Raw(string.Join("', '", Model.Choices))' ];

Please note, if you have 0 items, this will fail by adding one empty item to the array. You should ensure that the choices won’t have any ' (single quotes).
