Class property decorator hack. about babel-plugin-transform-decorators-legacy HOT 4 CLOSED

descriptor.initializer(); calls the initializer in the wrong place. You need to call initializer inside of _method.

@loganfsmyth I mean,

no matter what i do in descriptor function log. the Babel compile the code like below:

_descriptor = _applyDecoratedDescriptor(_class2.prototype, 'show', [log], {
        enumerable: true,
        initializer: function initializer() {
            var _this3 = this;
            return function() {
                console.info(_this3.name);
            }
            ;
        }
    })),

so, the this in show 'bind' to _this3 after compiled, _this3 is not the reference of instance, but the reference of class.prototype. thus, console.info(this.name) return undefined.

is there any method to solve this problem?

from babel-plugin-transform-decorators-legacy.

Write it as a method or assign a function instead of an arrow function:

	@log
	show(){
		console.info(this.name)   
	}

	@log
	show = function(){
		console.info(this.name)   
	}
