Knockoutjs:动态内容和 applyBindings
我像这样“动态”填充我的页面:
<script type="text/html" id="ContainerTemplate">
<span data-bind="template: {
name: contentTemplate,
data: contentData }"></span>
</script>
<script type="text/html" id="fooTemplate">
<span data-bind="text: barAttribute"></span>
</script>
<button data-bind="click: complete">complete</button>
Hello
<span data-bind="template: { name: 'ContainerTemplate', foreach: myContents }"></span>
!
ViewModel:
var viewModel = {
myContents: ko.observableArray([]),
complete: function() {
viewModel.myContents.push({
contentTemplate:'fooTemplate',
contentData:{barAttribute:'world'}});
}
};
ko.applyBindings(viewModel);
一个特殊之处是模板名称是动态的。它似乎是这样工作的(您可以在 http://jsfiddle.net/hPQNx/ 上尝试),但我想知道我做事是否正确。某些模板功能(例如根或父级)似乎不起作用。
我应该在某个时候手动重新调用 applyBindings 吗?我已经看到这必须在相关的 DOM 节点上完成,但是如何在我的设置中访问这些节点?
I am "dynamically" populating my page like this:
<script type="text/html" id="ContainerTemplate">
<span data-bind="template: {
name: contentTemplate,
data: contentData }"></span>
</script>
<script type="text/html" id="fooTemplate">
<span data-bind="text: barAttribute"></span>
</script>
<button data-bind="click: complete">complete</button>
Hello
<span data-bind="template: { name: 'ContainerTemplate', foreach: myContents }"></span>
!
ViewModel:
var viewModel = {
myContents: ko.observableArray([]),
complete: function() {
viewModel.myContents.push({
contentTemplate:'fooTemplate',
contentData:{barAttribute:'world'}});
}
};
ko.applyBindings(viewModel);
A particularity is that template names are dynamic. It seems to work like this (you can try it on http://jsfiddle.net/hPQNx/ ), but I wonder if I'm doing things correctly. Some template features like root or parent don't seem to be working.
Should I manually re-call applyBindings at some point ? I have seen this must be done on the related DOM nodes, but how can I access those nodes in my setup ?

我向您的视图模型添加了一个属性,并展示了如何添加根属性并使用
$root
引用它,并且$parent
可以在这个小提琴中工作。I added a property to your view model and showed how you can add a root property and reference it with
$root
and$parent
can work here in this fiddle.
