Question

i have an arrayX of three elements , and i’m using $.inArray() to search for this three element in another arrayY … and returning the location for each X element in Y

X = [1,2,3] ;
y = [1,5,6,1,6,9,3,2] ;

But there is duplication in y, 1 occurred twice in y[0] and y[3]

The real example is here http://jsfiddle.net/minagabriel/kHG9K/

How do I get the first 1 occupancy and skip the others?

I’m pushing the location of 1,2,3 in an array with the first occurred of each one

I just remove the item from the array once it has been found.

    if (start >= 0) {
        alert(y[i] + " " + "found it" + " " + " location" + z);
        y[i] = null;
    }

NOTE: That’s not the right way to loop through an array. Use for(index;index<length;index++) to avoid quirks.
