removeData()

removeData( [ name ] )

Returns: jQuery

version added: 1.2.3

Description: Remove a previously-stored piece of data.

Arguments

name (optional)

A string naming the piece of data to delete.

The .removeData() method allows us to remove values that were previously set using .data(). When called with the name of a key, .removeData() deletes that particular value; when called with no arguments, all values are removed.

Example

Set a data store for 2 names then remove one of them.

    $("span:eq(0)").text("" + $("div").data("test1"));
    $("div").data("test1", "VALUE-1");
    $("div").data("test2", "VALUE-2");
    $("span:eq(1)").text("" + $("div").data("test1"));
    $("div").removeData("test1");
    $("span:eq(2)").text("" + $("div").data("test1"));
    $("span:eq(3)").text("" + $("div").data("test2"));

The output of the code above will be:
