Question

I have an array.

I want to delete 78 from this array so i am using

 arr.splice($.inArray(78), 1);

but this always remove last element 89.

Plz help .

Answer 1

You have to pass the arr to jQuery.inArray:

$.inArray(78, arr)

You should also verify that the value was found before splicing:

var index = $.inArray(78, arr);
if (index > -1) {
    arr.splice(index, 1);
}

splice will treat the -1 to mean “1st from end” (or “last”).
