我可以创建在其中使用子标记的非空Knockout组件吗?
示例是用于显示模态对话框的组件,例如:
<modal-dialog>
<h1>Are you sure you want to quit?</h1>
<p>All unsaved changes will be lost</p>
</modal-dialog>
与组件模板一起:
<div class="modal">
<header>
<button>X</button>
</header>
<section>
<!-- component child content somehow goes here -->
</section>
<footer>
<button>Cancel</button>
<button>Confirm</button>
</footer>
</div>
输出:
<div class="modal">
<header>
<button>X</button>
</header>
<section>
<h1>Are you sure you want to quit?</h1>
<p>All unsaved changes will be lost</p>
</section>
<footer>
<button>Cancel</button>
<button>Confirm</button>
</footer>
</div>

3.2中不可能,但是在下一版本中可以使用,this commit和test。
目前您必须通过params
属性将参数传递给组件
将组件定义为content
参数:
ko.components.register('modal-dialog', {
viewModel: function(params) {
this.content = ko.observable(params && params.content || '');
},
template:
'<div class="modal">' +
'<header>' +
'<button>X</button>' +
'</header>' +
'<section data-bind="html: content" />' +
'<footer>' +
'<button>Cancel</button>' +
'<button>Confirm</button>' +
'</footer>' +
'</div>'
});
通过params
属性
<modal-dialog params='content: "<h1>Are you sure you want to quit?</h1> <p>All unsaved changes will be lost</p>"'>
</modal-dialog>
请参阅fiddle
在新版本中,您可以使用$componentTemplateNodes
ko.components.register('modal-dialog', {
template:
'<div class="modal">' +
'<header>' +
'<button>X</button>' +
'</header>' +
'<section data-bind="template: { nodes: $componentTemplateNodes }" />' +
'<footer>' +
'<button>Cancel</button>' +
'<button>Confirm</button>' +
'</footer>' +
'</div>'
});
P.S。您可以手动构建最后一个版本的knockout以使用上面的代码。
