Backbone.js 获取回调

Question

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.

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.

Thank you!

Answer 1

You're passing 2 separate arguments to fetch . Combine them into a single object with data , success , and error fields and it should work for you.

Example for x1a4 answer

 var myModel = new MyModel({id: modelId}); myModel.fetch({ success: function (model) { console.log('success: model fetched'); }, error: function () { console.log('error: loading model'); } });
