Backbone.js fetch callback
提问by dzm
I'm using Backbone.js and using fetch with options, but it doesn't seem to get the error or success callbacks, however data is being returned.
我正在使用 Backbone.js 并使用带选项的 fetch，但它似乎没有得到错误或成功回调，但是正在返回数据。
this.user.fetch({data: {username : this.username.val(), check : 'true'}}, {
error: function(model, response) {
console.log(response);
},
success: function(model, response) {
console.log(response);
}
});
This is what I have setup, am I missing something? It never hits error or success, but it does do the ajax request and it's returning data.
这是我设置的，我错过了什么吗？它永远不会出错或成功，但它确实会执行 ajax 请求并返回数据。
Thank you!
谢谢！

You're passing 2 separate arguments to fetch. Combine them into a single object with data, success, and errorfields and it should work for you.
您将 2 个单独的参数传递给fetch. 将它们与data、success和error字段组合成一个对象，它应该适合您。
