How to define custom sort function in javascript?

Question

I use atocomplete.jquery plugin to suggest input text, as the result I get this array:

['White 023','White','White flower', 'Teatr']

When I start to search something thats begin from te substring it shows me array sorting like this:

'White','White 023','White flower', 'Teatr'

I need something like this:

 'Teatr','White','White 023','White flower'

Any ideas?

Answer 1

It could be that the plugin is case-sensitive. Try inputting Te instead of te . You can probably have your results setup to not be case-sensitive. This question might help.

For a custom sort function on an Array , you can use any JavaScript function and pass it as parameter to an Array 's sort() method like this:

 var array = ['White 023', 'White', 'White flower', 'Teatr']; array.sort(function(x, y) { if (x < y) { return -1; } if (x > y) { return 1; } return 0; }); // Teatr White White 023 White flower document.write(array);

For Objects try this:

function sortBy(field) {
  return function(a, b) {
    if (a[field] > b[field]) {
      return -1;
    } else if (a[field] < b[field]) {
      return 1;
    }
    return 0;
  };
}

Answer 3

or shorter

 function sortBy(field) { return function(a, b) { return (a[field] > b[field]) - (a[field] < b[field]) }; } let myArray = [ {tabid: 6237, url: 'https://reddit.com/r/znation'}, {tabid: 8430, url: 'https://reddit.com/r/soccer'}, {tabid: 1400, url: 'https://reddit.com/r/askreddit'}, {tabid: 3620, url: 'https://reddit.com/r/tacobell'}, {tabid: 5753, url: 'https://reddit.com/r/reddevils'}, ] myArray.sort(sortBy('url')); console.log(myArray);

function msort(arr){
    for(var i =0;i<arr.length;i++){
        for(var j= i+1;j<arr.length;j++){
            if(arr[i]>arr[j]){
                var swap = arr[i];
                arr[i] = arr[j];
                arr[j] = swap;
            }
        }
    }
return arr;
}
