转换所有类型的字符串

var array = (new Function("return [" + str+ "];")());



var string = "0,1";

var objectstring = '{Name:"Tshirt", CatGroupName:"Clothes", Gender:"male-female"}, {Name:"Dress", CatGroupName:"Clothes", Gender:"female"}, {Name:"Belt", CatGroupName:"Leather", Gender:"child"}';

var stringArray = (new Function("return [" + string+ "];")());

var objectStringArray = (new Function("return [" + objectstring+ "];")());

控制台结果

一些练习不支持对象字符串

- JSON.parse("[" + string + "]"); // throw error

 - string.split(",") 
// unexpected result 
   ["{Name:"Tshirt"", " CatGroupName:"Clothes"", " Gender:"male-female"}", "      {Name:"Dress"", " CatGroupName:"Clothes"", " Gender:"female"}", " {Name:"Belt"",    " CatGroupName:"Leather"", " Gender:"child"}"]

正则表达式

作为分割的更强大的替代品，你可以使用匹配

"0,1".match(/\d+/g)

Let a = "0,1".match(/\d+/g) console.log(一个);

如何转换逗号分隔字符串成一个数组在JavaScript?

var string = 'hello, world, test, test2, rummy, words';
var arr = string.split(', '); // split string on comma space
console.log( arr );
 
//Output
["hello", "world", "test", "test2", "rummy", "words"]

在javascript中使用以下方式转换字符串到数组的更多示例:

Split() -没有分隔符: Split() -空字符串分隔符: Split() -开始/结束的分隔符: 正则表达式分隔符: 捕捉括号: 带有Limit参数的Split() 看看这个链接 = = > https://www.tutsmake.com/javascript-convert-string-to-array-javascript/

分了就分了，人品;

var string = "0,1";
var array = string.split(",");
alert(array[0]);

为什么不像这样替换，逗号和分割(")字符串，这将导致['0'，'1']，此外，您可以将结果包装到parseInt()将元素转换为整数类型。

it('convert string to array', function () {
  expect('0,1'.replace(',', '').split('')).toEqual(['0','1'])
});

使用ES6的另一个选项是使用扩展语法。

var convertedArray =[…"01234"];

var stringToConvert = "012"; var convertedArray =[…stringToConvert]; console.log (convertedArray);
