Object.assign()

• In the use of element Use object assignment in the process of this.temp=this.listQuery Modifying the table form in temp When the value is found in the description object listQuery Data changes together .
• Finally found ,JS The assignment of objects is by default reference .
  Search for relevant information , Found that you can use Object.assign() solve

• Official explanation

Object.assign() Method is used to assign the values of all enumerable properties from one or more source objects to the target objects . It will return the target object .

const target = {
     a: 1, b: 2 };
const source = {
     b: 4, c: 5 };

const returnedTarget = Object.assign(target, source);

console.log(target);
// expected output: Object {
     a: 1, b: 4, c: 5 }

console.log(returnedTarget);
// expected output: Object {
     a: 1, b: 4, c: 5 }

So after the change this.temp = Object.assign({}, this.listQuery); So it won't change with it .
