将 TypeScript object 转换为 JSON

Question

I want to convert a typescipt object to JSON

ObjectToConvert = { key : value }

public getJson(key: string, value: string) {
    //I passed this values when I called the method : key="attr",value="on"
   console.log(JSON.stringify({ ObjectToConvert }))
   // The result is {"key":"on"} instead of {"attr":"on"}
   

I want to know why the result is not what I passed as parameter.

Answer 1

Use computed property names :

ObjectToConvert = { [key] : value }
