将具有键值对的字符串映射到对象

Question

给定以下带键值对的字符串，如何编写通用函数将其映射到对象？

目前，我只是按getExerciseDescription(exerciseId, intensity_level){ alert(exerciseId + " " + intensity_level) switch (exerciseId && intensity_level) { case (1 && 1): this.header="Exercise 1 Level 1"; this.instructions="Exercise 1 Level 1"; break; case (1 && 2): this.header="Exercise 1 Level 2"; this.instructions="Exercise 1 Level 2"; break; case (2 && 1): this.header="Exercise 2 Level 1"; this.instructions="Exercise 2 Level 1"; break; case (2 && 2): this.header="Exercise 2 Level 2"; this.instructions="Exercise 2 Level 2"; break; default: this.header="Default"; this.instructions="Default"; break; } return new Popup(this.header, this.instructions); } 和:进行拆分以获取相关数据，但这似乎不是一种干净的方法。

此刻我的代码：

使用reduce：

＆＃13;

＆＃13;

function objectify(str) {

	return str.split(";").reduce(function (obj, item) {
		var a = item.split(":");
		obj[a[0]] = a[1];
		return obj;
	}, {});

}

var strObj = "id:S76519;sku:S76519;name:StarGazer 3000;model:ICC74";
console.log(objectify(strObj));

＆＃13;

＆＃13;

＆＃13;

或：

＆＃13;

＆＃13;

function objectify(str){

return str.split(";").reduce((obj,item)=>{  
   var a = item.split(":");
   obj[a[0]]=a[1];
   return obj;  
},{});

}
 
var strObj = "id:S76519;sku:S76519;name:StarGazer 3000;model:ICC74";
console.log(objectify(strObj));

＆＃13;

＆＃13;
