JavaScript将字符串转换为运算符

比如说

{obj1} '==' {obj2}

{obj1} == {obj2}

或

{obj1} '!==' {obj2}

应该是:

{obj1} !== {obj2}

我可以用 eval() ,但这会强制将要比较的对象转换为字符串,从而导致 === (严格的类型检查)比较无效。

eval 将给出错误的结果:

const obj = "5"
const obj2 = 5

const operator = '===';

eval(`console.log(${obj} ${operator} ${obj2})`) //outputs true, incorrect (obj is of type string, obj2 is of type number)

console.log(obj === obj2) //outputs false, correct

可能的方法

差不多

if(condition === '!=='){
  return before_OrderRequest.Id !== after_OrderRequest.Id
}else if (condition === '==='){
  return before_OrderRequest.Id === after_OrderRequest.Id
}
//...more if statements
