javascript - 部分覆盖 Backbone.sync

Question

有什么方法可以部分覆盖 Backbone.sync，比如说，只覆盖 create 和 update，而保留 read 和 delete 使用 native Backbone.sync？

Answer 1

就这么简单:

// retain original sync with new name
Backbone.ajaxSync = Backbone.sync;

Backbone.customSync = function(method, model, option) {
    // Fallback for old sync method
    if (method == 'read' || method == 'delete') return Backbone.ajaxSync(method, model, option);

    // your custom code for other methods
    console.log('Custom sync for ' + method);
}

Backbone.sync = Backbone.customSync;
