有没有办法为 JSON.parse reviver 提供上下文？

Question

So I am formatting data inside JSON Strings and I need to use my application context (like this.name etc.) INSIDE the reviver.

Code example of reviver:

formatReviver = function (key, value) {

 if(context.name === value)
 //do stuff

}

But obviously THIS does not work inside the Reviver.

An idea I had is to use default values inside the parameter:

formatReviver = function (key, value, context = window) {

 if(context.name === value)
 //do stuff

}

Any other ideas?

Answer 1

you can bind the reviver to the current context.

formatReviver = (function (key, value) {
 if(this.name === value)
 //do stuff

}).bind(this)

Or use an arrow function, it automatically binds this .

formatReviver = (key, value) => {
 if(this.name === value)
 //do stuff
}
