问使用ES6类封装AJAX

EN

const $ = require('jquery');

class ModelLoader {
    static loadCsvFile(path, callback, options) {
        this.callback = callback;
        $.get(path, this._loadCsvFile);
    }

    static _loadCsvFile(data) {
        ModelLoader.callback(); // using this.callback() doesn't work because this here is AJAX object
    }
}

module.exports = ModelLoader;

ModelLoader.loadCsvFile('model1.csv', callback1);
ModelLoader.loadCsvFile('model2.csv', callback2);
