好的，所以这开始让我疯了。我现在有几个小时的搜索和搜索，每一个解决方案都不适合我。所以是的，这个问题可能是多余的，但我不能让我的生活得到解决方案。
我有一堆复选框由jquery模板生成，该模板通过knockout.js进行数据绑定。然而，它变得没有风格。 Afaik，它是关于jquery mobile的东西，在淘汰赛之前的样式渲染模板，所以它最终没有样式。 我尝试了很多方法无济于事，所以我希望有人能看到我做错了什么。
（我正在使用jquery mobile 1.2.0，jquery 1.8.2和knockout 2.2.1）
这是脚本：
<script type="text/javascript">
jQuery.support.cors = true;
var dataFromServer = "";
// create ViewModel with Geography, name, email, frequency and jobtype
var ViewModel = {
email: ko.observable(""),
geographyList: ["Hovedstaden","Sjælland","Fyn + øer","Nordjylland","Midtjylland","Sønderjylland" ],
selectedGeographies: ko.observableArray(dataFromServer.split(",")),
frequencySelection: ko.observable("frequency"),
jobTypes: ["Kontor (administration, sekretær og reception)","Jura","HR, Ledelse, strategi og udvikling","Marketing, kommunikation og PR","Handel og service (butik, service, værtinde og piccoline)","IT","Grafik og design","Lager, chauffør, bud mv.","Økonomi, regnskab og finans","Kundeservice, telefoninterview, salg og telemarketing","Sprog","Øvrige jobtyper"],
selectedJobTypes: ko.observableArray(dataFromServer.split(",")),
workTimes: ["Fulltid","Deltid"],
selectedWorkTimes: ko.observableArray(dataFromServer.split(","))
};
// function for returning checkbox selection as comma separated list
ViewModel.selectedJobTypesDelimited = ko.dependentObservable(function () {
return this.selectedJobTypes().join(",");
}, ViewModel);
var API_URL = "/webapi/api/Subscriptions/";
// function used for parsing json message before sent
function omitKeys(obj, keys) {
var dup = {};
var key;
for (key in obj) {
if (obj.hasOwnProperty(key)) {
if (keys.indexOf(key) === -1) {
dup[key] = obj[key];
}
}
}
return dup;
}
//Function called for inserting new subscription record
function subscribe() {
if($("#jobmailForm").valid()=== true){
//window.alert("add subscriptiooncalled");
var mySubscription = ko.toJS(ViewModel);
//var json = JSON.stringify(mySubscription);
var jsonSmall = JSON.stringify(omitKeys(mySubscription, ['geographyList','jobTypes','selectedJobTypesDelimited','workTimes']));
//window.alert(jsonSmall);
$.ajax({
url: API_URL,
cache: false,
type: 'POST',
contentType: 'application/json',
data: jsonSmall,
success: function (data) {
window.alert("success");
},
error: function (error) {
window.alert("ERROR STATUS: " + error.status + " STATUS TEXT: " + error.statusText);
}
});
}
}
function initializeViewModel() {
// Get the post from the API
var self = this; //Declare observable which will be bind with UI
// Activates knockout.js
ko.applyBindings(ViewModel);
}
// Handle the DOM Ready (Finished Rendering the DOM)
$("#jobmail").live("pageinit", function() {
initializeViewModel();
$('#jobmailDiv').trigger('updatelayout');
});
</script>
<script id="geographyTmpl" type="text/html">
<input type="checkbox" data-role="none" data-bind="attr: { value: $data }, attr: { id: $data }, checked: $root.selectedGeographies" />
<label data-bind="attr: { for: $data }"><span data-bind="text: $data"></span></label>
</script>
<script id="jobTypeTmpl" type="text/html">
<label><input type="checkbox" data-role="none" data-bind="attr: { value: $data }, checked: $root.selectedJobTypes" /><span data-bind="text: $data"></span></label>
</script>
注意，“jobmail”是周围的“page”div元素，此处未显示。这是标记：
<div data-role="content">
<umbraco:Item field="bodyText" runat="server"></umbraco:Item>
<form id="jobmailForm" runat="server" data-ajax="false">
<div id="jobmailDiv">
<p>
<label for="email">Email</label>
<input type="text" name="email" id="email" class="required email" data-bind="'value': email" />
</p>
<fieldset data-role="controlgroup" data-mini="true" data-bind="template: { name: 'geographyTmpl', foreach: geographyList, templateOptions: { selections: selectedGeographies } }">
<input type="checkbox" id="lol" />
<label for="lol">fkfkufk</label>
</fieldset>
<fieldset data-role="controlgroup" data-mini="true">
<p data-bind="template: { name: 'jobTypeTmpl', foreach: jobTypes, templateOptions: { selections: selectedJobTypes } }"></p>
</fieldset>
<fieldset data-role="controlgroup" data-mini="true">
<input type="radio" id="frequency5" name="frequency" value="5" data-bind="checked: frequencySelection" /><label for="frequency5">Højst 5 gange om ugen</label>
<input type="radio" id="frequency3" name="frequency" value="3" data-bind="checked: frequencySelection" /><label for="frequency3">Højst 3 gange om ugen</label>
<input type="radio" id="frequency1" name="frequency" value="1" data-bind="checked: frequencySelection" /><label for="frequency1">Højst 1 gang om ugen</label>
</fieldset>
<p>
<input type="button" value="Tilmeld" class="nice small radius action button" onClick="subscribe();">
</p>
<a href="{locallink:1733}" data-role="button" data-icon="back" data-inline="true" data-direction="reverse">Tilbage</a>
</div>
</form>
调用重新定位的替代方法（也不起作用）：
$(document).on('pagebeforeshow', '#jobmail', function(){
// Get the post from the API
var self = this; //Declare observable which will be bind with UI
// Activates knockout.js
ko.applyBindings(ViewModel);
});
// Handle the DOM Ready (Finished Rendering the DOM)
$("#jobmail").live("pageinit", function() {
$('#jobmail').trigger('pagecreate');
});

使用自定义绑定（Knockout）触发jQuery Mobile 增强由Knockout生成的动态创建的内容。
这是一个简单的自定义绑定：
ko.bindingHandlers.jqmEnhance = {
update: function (element, valueAccessor) {
// Get jQuery Mobile to enhance elements within this element
$(element).trigger("create");
}
};
在HTML中使用自定义绑定，其中myValue是视图模型中更改的部分，触发动态内容插入DOM：
<div data-bind="jqmEnhance: myValue">
<span data-bind="text: someProperty"></span>
<a href="#some-id" data-role="button">My Button</a>
<input type="radio" id="my-id" name="my-name" value="1" data-bind="checked: someOtherProperty" /><label for="my-id">My Label</label>
</div>
就我自己而言，myValue是if绑定中表达式的一部分，它会触发将内容添加到DOM中。
<!-- ko if: myValue -->
<span data-bind="jqmEnhance: myValue">
<!-- My content with data-bind attributes -->
</span>
<!-- /ko -->
