Question

考虑具有以下值的数组数组

var myArray = [
                  ["2001-05","Tom","1000"],
                  ["2001-05","Harry","500"],
                  ["2002-06","Harry","3000"],
                  ["2002-06","Tom","2000"],
                   ....

上面的数组已根据第一个元素排序，即年份，但是我也希望根据第二个元素对数组进行排序年组。

输出就像，

      var myArray = [
              ["2001-05","Harry","500"],
              ["2001-05","Tom","1000"],
              ["2002-06","Harry","3000"],
              ["2002-06","Tom","2000"],
               ....

除了使用嵌套循环进行排序之外，我们可以将数组排序为javascript中的分组排序数组或使用jquery。

尝试以下方法：

var myArray = [
            ["2001-05","Tom","1000"],
            ["2001-05","Harry","500"],
            ["2002-06","Harry","3000"],
            ["2002-06","Tom","2000"]
          ];
var sortedArray = myArray.sort(function (a, b) {  
    return Number(a[0].replace('-','')) - Number(b[0].replace('-','')) || a[1] > b[1];
});

console.log(sortedArray);

尝试以下方法：

var myArray = [
                ["2001","Harry","500"],
                ["2002","Harry","3000"],
                ["2002","Tom","2000"],
                ["2001","Tom","1000"]
              ];
              
var sorted = myArray.sort((a,b) =>{
  if(a[0] !== b[0])
    return a[0] > b[0];
   else if(a[1] !== b[1])
    return a[1] > b[1];
});
console.log(sorted);

只需使用数组sort()即可。它将正确排序数组。

var sortedArray = myArray.sort(function(a, b) {  
  return a > b ? 1 : -1;
});

使用组对数组数组进行排序
