部分覆盖Backbone.sync

Question

有没有办法部分覆盖Backbone.sync，比如仅create和update，并让read和delete使用本机Backbone.sync？< / p>

Answer 1

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;
