你可以使用split

参考: http://www.w3schools.com/jsref/jsref_split.asp

“0 1”.split (" ")

你可以使用javascript扩展语法将字符串转换为数组。在下面的解决方案中，我删除了逗号，然后将字符串转换为数组。

var string = "0,1"
var array = [...string.replace(',', '')]
console.log(array[0])

对于这样的简单数组成员，可以使用JSON.parse。

var listValues = "[{\"ComplianceTaskID\":75305,\"RequirementTypeID\":4,\"MissedRequirement\":\"Initial Photo Upload NRP\",\"TimeOverdueInMinutes\":null}]";

var array = JSON.parse("[" + listValues + "]");

这给了你一个数字数组。

现在你的变量值是array。length=1

值输出

array[0].ComplianceTaskID
array[0].RequirementTypeID
array[0].MissedRequirement
array[0].TimeOverdueInMinutes

使用Array.filter的示例:

var str = 'a,b,hi,ma,n,yu';

var strArr = Array.prototype.filter.call(str, eachChar => eachChar !== ',');

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"}"]

Split("，")可以将带有逗号的字符串转换为字符串数组，这是我的代码片段。

    var input ='Hybrid App, Phone-Gap, Apache Cordova, HTML5, JavaScript, BootStrap, JQuery, CSS3, Android Wear API'
    var output = input.split(",");
    console.log(output);

["混合应用"，" Phone-Gap"， " Apache Cordova"， " HTML5"， " JavaScript"， " BootStrap"， " JQuery"， " CSS3"， " Android Wear API"]
