我是网络编程的新手,我正在尝试将Knockout Contact表单实现到我使用MVC 4 Razor构建的网站上.我直接从Knockout的网站上看到了这个例子并测试了我在JSFiddle中的变化;一切都很好.但是当我将代码带入我的cshtml时,它将不会获取Knockout代码.我对正在发生的事情感到茫然.有帮助吗?细节将是有益的,因为有很多我不知道.在cshtml上的Knockout联系人网格之后有一个BeginForm帮助器.这是一个问题吗?
Javascript:AddTeamMember.js
var initialData = [
{
name: "Danny", email: "LaRusso@stars.come", phone: "(555) 121-2121", dept: "Print"
},
{
name: "Sensei", email: "Miyagi@stars.com", phone: "(555) 432-3466", dept: "AMS"
}
];
var ContactsModel = function (contacts) {
var self = this;
self.contacts = ko.observableArray(ko.utils.arrayMap(contacts, function (contact) {
return { name: contact.name, email: contact.email, phone: contact.phone, dept: contact.dept };
}));
self.addContact = function () {
self.contacts.push({
name: "",
email: "",
phone: "",
dept: ""
});
};
self.removeContact = function (contact) {
self.contacts.remove(contact);
};
self.addPhone = function (contact) {
contact.phones.push({
type: "",
number: ""
});
};
self.removePhone = function (phone) {
$.each(self.contacts(), function () { this.phones.remove(phone) })
};
self.save = function () {
self.lastSavedJson(JSON.stringify(ko.toJS(self.contacts), null, 2));
};
self.lastSavedJson = ko.observable("")
};
ko.applyBindings(new ContactsModel(initialData));

解决方法:
当您的DOM准备就绪时,必须执行此行.
ko.applyBindings(new ContactsModel(initialData));
引自KO网站:
To activate Knockout, add the following line to a block:
06001
You can either put the script block at the bottom of your HTML
document, or you can put it at the top and wrap the contents in a
DOM-ready handler such as jQuery’s $function.
