The conversion between JS string and array

One: string conversions to arrays

Example:

var str = "3:2;2:1";

To become

arr= [{

A: "3",

B: "2",

Bol:false

},{

A: "2",

B: "1",

Bol:false

}]

Realize:

　　　　

            var arr = Str.split (";");            var SRR = [];            for (Let index = 0; index < arr.length; index++) {                Srr.push ({                    a:arr[index].split (":") [0],                    B:arr[index]. Split (":") [1],                    bol:false,                })            }            

The SRR is the desired array;

Two: arrays are converted into strings

Example:

　　

arr= [{

A: "3",

B: "2",

Bol:false

},{

A: "2",

B: "1",

Bol:false,

}]

To become:

str = "3:2;2:1";

Realize:

　　

            var str = "";            for (var index = 0; index < arr.length; index++) {                 if (arr[index].a = = "" "| | arr[index].b = = "" | | This.fzz = = "" | | This.yzz = = "") {this                    . $message (' cannot have null values in the ' Ride Card settings ');                } else{                    str = str+arr[index].a+ ":" +arr[index].b+ ";";                }                          }            str = str.substring (0,str.length-1);
