How to implement Chinese A-Z sorting in vue.js or js

Below I will share with you a method of implementing Chinese A-Z sorting in vue.js or js. It has a good reference value and I hope it will be helpful to everyone.

To implement Chinese according to the A-Z method, you can write in the methods of vue:

methods:{
        pySort:function(arr,empty){
          var $this = this;
          if(!String.prototype.localeCompare)
            return null;
          var letters = "ABCDEFGHJKLMNOPQRSTWXYZ".split('');
          var zh = "阿八嚓哒妸发旮哈讥咔垃痳拏噢妑七呥扨它穵夕丫帀".split('');
          var arrList = [];
          for(var m =0;m<arr.length;m++){
            arrList.push(arr[m].name);
          }
          var result = [];
          var curr;
          for(var i=0;i<letters.length;i++){
            curr = {letter: letters[i], data:[]};
            if(i!=26){
              for(var j =0;j<arrList.length;j++){
                var initial = arrList[j].charAt(0);//截取第一个字符
                if(arrList[j].charAt(0)==letters[i]||arrList[j].charAt(0)==letters[i].toLowerCase()){  //首字符是英文的
                  curr.data.push(arrList[j]);
                }else if(zh[i]!=&#39;*&#39;&&$this.isChinese(initial)){   //判断是否是无汉字,是否是中文
                  if(initial.localeCompare(zh[i]) >= 0 &&(!zh[i+1]||initial.localeCompare(zh[i+1]) <0)) {  //判断中文字符在哪一个类别
                    curr.data.push(arrList[j]);
                  }
                }
              }
            }else{
              for(var k =0;k<arrList.length;k++){
                var ini = arrList[k].charAt(0);      //截取第一个字符
                if(!$this.isChar(ini)&&!$this.isChinese(ini)){
                  curr.data.push(arrList[k]);
                }
              }
            }
            if(empty || curr.data.length) {
              result.push(curr);
              //curr.data.sort(function(a,b){
              //  return b.localeCompare(a);    //排序,英文排序,汉字排在英文后面
              //});
            }
          }
          return result;
        },
        isChinese:function(temp){
          var re=/[^\u4E00-\u9FA5]/;
          if (re.test(temp)){return false;}
          return true ;
        },
        isChar:function(char){
          var reg = /[A-Za-z]/;
          if (!reg.test(char)){return false ;}
          return true ;
        }
       }

Convert the json object obtained from php into an array, and call it directly in vue ->this.pySort(arr); js can directly call the pySort(arr) method. Achieve sorting according to the format of A-Z

The format shown in the console output is as shown below:

letter Store key values ​​A-Z

data: store the sorted array

As for vue, which needs to be placed on the page, use v-for loop v-for="(key, value) in arr"

You need to get the value of the data array, continue to use v-for="tmp in (key.data)" to loop in the elements you want to enter and place

It is relatively simple to write , this method is also common in js

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
