我的代码是实现一个像这个例子一样的分页页面,https://github.com/bitovi/canjs/blob/master/component/examples/paginate.html。
我发现 message.mustache 模板中的 {#messages}...{/messages} 没有被插入到页面中,而 messagelist 组件插入事件已被触发,所以我无法对中的 {#messages} dom 进行任何绑定事件,因为它在页面中不存在。
还有其他方法可以解决此问题吗?
模板:
message_list.mustache:
<app>
<messagelist deferredData='messagesDeferred'></messagelist>
<next-prev paginate='paginate'></next-prev>
<page-count page='paginate.page' count='paginate.pageCount'></page-count>
</app>
message.mustache:
{#messages}}
<dl>
<dt>.....</dt>
<dd>....</dd>
</dl>
{/messages}
组件:
can.Component.extend({
tag: "messagelist",
template: can.view('/static/web/tpl/mobile/message.mustache'), // to load message template
scope: {
messages: [],
waiting: true,
},
events: {
init: function () {
this.update();
},
"{scope} deferreddata": "update",
update: function () {
var deferred = this.scope.attr('deferreddata'),
scope = this.scope,
el = this.element;
if (can.isDeferred(deferred)) {
this.scope.attr("waiting", true);
deferred.then(function (messages) {
scope.attr('messages').replace(messages);
});
} else {
scope.attr('messages').attr(deferred, true);
}
},
"{messages} change": function () {
this.scope.attr("waiting", false);
},
inserted: function(){
// can't operate the dom in message.mustache template
}
}
});
//to load component template
can.view("/static/web/tpl/mobile/message_list.mustache",{}, function(content){
$("#message-list").html(content)
});
