Efficient Searching in jQuery

Question

I want to be able to pass an array (even an array of jQuery objects) and do a simple search based on a single data member.

It'd take an array to search, a string for the data member, and the value to search for.

This is obviously easy to write myself, but I was curious if jQuery had anything built in to do this already?

Thanks SO!

Answer 1

var arr = [
    {key1 : 'value 1-1', key2    : 'value 2-1'},
    {key1 : 'value 1-2', key2NOT : 'value 2-2'},
    {key1 : 'value 1-3', key2    : 'value 2-3'},
    {key1 : 'value 1-4', key2NOT : 'value 2-4'}
],
    data_member = 'key2',
    output      = {};

$.each(arr, function (index, obj) {
    if (data_member in obj) {
        output[index] = obj[data_member];
    }
});
