javascript数组排序汇总

//排序算法
  window.onload = function(){
    var array = [0,1,2,44,4,
          324,5,65,6,6,
          34,4,5,6,2,
          43,5,6,62,43,
          5,1,4,51,56,
          76,7,7,2,1,
          45,4,6,7,8];
    //var array = [4,2,5,1,0,3];
    console.log('原始数组');
    console.log(array);
    array = sorting.shellSort(array);
    // alert(array);
    console.log('排序后的数组')
    console.log(array);
  }
   
  var sorting = {
    //利用sort方法进行排序
    systemSort: function(arr){
      return arr.sort(function(a,b){
        return a-b;
      });
    },
   
    //冒泡排序
    bubbleSort: function(arr){
      var len=arr.length, tmp;
      for(var i=0;iarr[j+1]){
            tmp = arr[j];
            arr[j] = arr[j+1];
            arr[j+1] = tmp;
          }
        }
      }
      return arr;
    },
   
    //快速排序
    quickSort: function(arr){
      var low=0, high=arr.length-1;
      sort(low,high);
      function sort(low, high){
        if(low=tmp){
                high--;
              }
              arr[low] = arr[high];
              while(low=0;j--){
          if(tmp=1;h=Math.floor(h/3)){
        for(var k=0;k=h&&arr[j]
