jquery if variable in a list of values

Question

I have some jquery checking the choice made in a drop down.

function toggleFields() {
if ($("#chosenmove1").val() == 4)
    $("#hideme").show();
else
    $("#hideme").hide();
}

This works fine but I would like to change it so it checks a list of values like

if ($("#chosenmove1").val() in (3,4,5))

How can I write this to make it work (the above doesn't)

Tried a bit more

var arr = [3,4,5];
var value = $("#chosenmove1").val();
alert(value);

if ($.inArray(value, arr) > -1)
    $("#hideme").show();
else
    $("#hideme").hide();

}

The alert box tells me var value is getting the right value from the drop down - yet the show hide wont work under this setup. IF I replace var value = $("#chosenmove1").val(); with var value = 3; then it does work?

looks like that's what i mean - i want to check if the user has clicked on the drop down with the corresponding value of either 3,4 or 5 — user1479891, Mar 30 '15 at 12:22

Below is my working code: the array numbers needed to be in quotes?

function toggleFields() {
var arr = ['3','4','5'];
var value = $("#chosenmove1").val();

if (jQuery.inArray(value, arr) > -1)
    $("#hideme").show();
else
    $("#hideme").hide();

}

This answer is actually better if you're using strings. `arr.indexOf` does not seem to play nice with strings in @Richard Macarthy's answer. – Bing Jun 14 '18 at 23:28

You can use indexOf

var arr=[1,2,3];

if(!arr.indexOf(1)){ // Your value here
    alert("exists");
}
