Javascript 将Knockout.JS viewmodel绑定到jQuery对话框
我有一个jQuery模式对话框，我想在其中传递来自淘汰视图模型的数据。对话框按原样工作正常-但是，下面的代码被破坏 理想情况下，我希望能够单击触发模式对话框的URI，并让对话框从敲除viewmodel加载数据。任何帮助都将不胜感激 标记：Javascript 将Knockout.JS viewmodel绑定到jQuery对话框,javascript,jquery,knockout.js,Javascript,Jquery,Knockout.js,我有一个jQuery模式对话框，我想在其中传递来自淘汰视图模型的数据。对话框按原样工作正常-但是，下面的代码被破坏 理想情况下，我希望能够单击触发模式对话框的URI，并让对话框从敲除viewmodel加载数据。任何帮助都将不胜感激 标记： <a href="#" id="listNames">List Names</a> <div id="listNames" data-bind="dataModel: { autoOpen: false, modal: tr

您发布的代码中有一些错误。 我这里有一个工作版本： 以下是HTML:
var dataModel = function (edata) {
var self = this;
self.edata = ko.observableArray(edata);
self.addname = function () {
self.edata.push({
name: "",
age: ""
});
};
self.removename = function (name) {
self.edata.remove(name);
};
self.save = function (form) {
alert("Could now transmit to server: "
+ ko.utils.stringifyJson(self.edata));
// To actually transmit to server as a regular form post, write this:
// ko.utils.postJson($("form")[0], self.edata);
};
};
var viewModel = new dataModel([
{ name: "Jack", age: "41" },
{ name: "Jill", age: "33" }
]);
ko.applyBindings(new viewModel);
