Javascript splice not working

Question

I may be wrong on what I think .splice() is meant to do, but I thought it removed one element of an array. All I want to do here is remove "pears", but it doesn't work:

var my_array = ["apples","pears","bananas","oranges"];

my_array.splice($.inArray("pears",my_array));

$.each(my_array, function(k,v) {
    document.write(v+"<br>");
});

Answer 1

You're missing two arguments:

• $.inArray wants the second argument to be the subject array
• splice accepts a second argument to specify the number of elements to be deleted

The code becomes:

var my_array = ["apples","pears","bananas","oranges"];

my_array.splice($.inArray("pears", my_array), 1);

$.each(my_array, function(k,v) {
    document.write(v+"<br>");
});
