淘汰赛和JQuery for Ajax表单提交

Question

I'm having trouble getting the Knockout.js submit binding to work. I have the following element:

<form data-bind="submit: postPreference">

and my viewModel defines:

var ViewModel = function (data) {
  var self = this;
  ko.mapping.fromJS(data, {}, self);

  self.postPreference = function (form) {
    $.post("@{PreferenceR}", form.serialize(), function (data) {
      $.bootstrapGrowl("Your preferences were saved.", {type: 'success'});
    });
  }
};

However, I am getting an error which says that form is undefined at the call site for serialize .

Answer 1

您需要使用$（form）.serialize（）
