How to check from an array

Question

var a=new Array;
for (j=0;j<=10;j++) {
a[j]=Math.floor(Math.random()*99)+2
}

var check=Math.floor(Math.random()*99)+2

So how do I check whether check is a value of any of the a[j] (that is a[0] to a[10])? A good and simple method?

Try this:

a.indexOf(check) > -1

It does not work! I want that if it matches that criteria, the program can execute some code using the if statement or the ternary operator. – user2028943 Feb 10 '13 at 14:38
@user2028943: What exactly does not work? `.indexOf` tests whether a value is contained in the array. – Felix Kling Feb 10 '13 at 14:39
Ya thanks, it was my mistake! It works! – user2028943 Feb 10 '13 at 14:46
