自然排序数组

Question

I need to sort an array of arrays given to me. The array looks something like this.

var provided_array = [
    inner_array_one = ['1', '10', '11', 'Alpha', '2A'],
    inner_array_two = ['Hotdogs', 'Pies', 'Burgers', 'Kebabs', 'Tacos']
    ];

I've kept this example as minimal as possible. In reality there are usually about a dozen of these inner arrays.

The data in inner_array_one is related to that of inner_array_two by index. Ie "2A" is related to "Tacos".

The sorting needs to be "natural" ie 2 before 10. The overall expected output I need is

provided_array[
    inner_array_one['1', '2A', '10', '11', 'Alpha'],
    inner_array_two['Hotdogs', 'Tacos', 'Pies', 'Burgers', 'Kebabs']
    ];

I've tried to use the javascript sort function but it seems it's only capable of sorting the order of the inner_arrays and not the content of those said arrays.

Is what I want achievable?

Answer 1

You could take a helper array for the indices and sort natural the first inner array and map all arrays with the indices array.

 var arrays = [ ['1', '10', '11', 'Alpha', '2A'], ['Hotdogs', 'Pies', 'Burgers', 'Kebabs', 'Tacos'] ], indices = Object.keys(arrays[0]); indices.sort((a, b) => arrays[0][a].localeCompare(arrays[0][b], undefined, { numeric: true, sensitivity: 'base' })); console.log(arrays.map(a => indices.map(i => a[i]))); 

 .as-console-wrapper { max-height: 100% !important; top: 0; } 

Answer 2

This simple function would sort an array of arrays at any level of nesting:

function sortArray(arr) {
    if (!Array.isArray(arr) || !arr.length) return;
    if (Array.isArray(arr[0]))
        arr.forEach(ele => sortArray(ele));
    arr = arr.sort();
}

Answer 3

You can use the kn option of .localeCompare() for natural sorting of alphanumeric strings.

var provided_array = [
    inner_array_one = ['1', '10', '11', 'Alpha', '2A'],
    inner_array_two = ['Hotdogs', 'Pies', 'Burgers', 'Kebabs', 'Tacos']
    ];


provided_array.forEach(item => item.sort((obj1, obj2) => obj1.localeCompare(obj2, 'en-US-u-kn-true')));


console.log(provided_array);
