js将{"PageNum":1,"PageSize":20,"Yearly":"","State":"","Type":""}:写为{ PageNum: 1, PageSize: 20, Yearly: "", State: "", Type: "" }

可以使用JavaScript中的对象字面量语法将{"PageNum":1,"PageSize":20,"Yearly":"","State":"","Type":""}写为{
PageNum: 1,
PageSize: 20,
Yearly: "",
State: "",
Type: ""
}。具体实现方法如下所示：

const obj = {"PageNum":1,"PageSize":20,"Yearly":"","State":"","Type":""};
const newObj = {
  PageNum: obj.PageNum,
  PageSize: obj.PageSize,
  Yearly: obj.Yearly,
  State: obj.State,
  Type: obj.Type
};
console.log(newObj); // 输出：{ PageNum: 1, PageSize: 20, Yearly: '', State: '', Type: '' }

其中，我们首先定义了一个包含原始数据的对象obj，然后使用对象字面量语法创建了一个新的对象newObj，并将obj中的属性值赋值给newObj中对应的属性名。最后，我们输出了新的对象newObj，即可得到所需的结果。
