[英]How to perform event bubbling in meteor template helper
我正在嘗試捕獲整個{{#each categories}}
數據,但我使用的按鈕.toggle-addToSet
並沒有捕獲到頂部,而是僅捕獲了{{#each set}}
{{#each categories}}
遺憾,我所需的數據不在其中,因此我需要一種方法來捕獲{{#each set}}
以外的數據,一直到{{#each categories}}
這就是HTML中的樣子
<ul>
{{#each categories}}
<li class="myIdd">
<div class="row col s12 m7">
<div class="card" id="cardId">
<div class="card-image waves-effect waves-block waves-light">
<a href="/latestSingle/{{_id}}"><img src="{{better_featured_image.source_url}}"></a>
</div>
<div class="card-content">
<h5 class=" truncate grey-text text-darken-4">{{title.rendered}}</h5>
<a href="/latestSingle/{{_id}}">MORE</a> <a href="#modal2" class="modal-trigger waves-effect waves-light" onclick="Materialize.showStaggeredList('#bottom-options')"><i class="waves-effect waves-teal small material-icons right">playlist_add</i></a>{{>
likePartial}}{{> reblogPartial}}
<!-- The modal below is what brings up all the sets the user has created so that the user can pick with set they wat to save the article in -->
<div id="modal2" class="modal bottom-sheet">
<div class="modal-content">
<div class="row">
<!-- data being captured is only below this, but i need it to capture up until li class ="myIdd" -->
{{#each set}}
<div class="col s6 m6 addSet teal">
<div class="card ">
<div class="card-image">
<span class="card-title cardSet">{{name}}</span>
</div>
<div class="card-footer">
<!-- This button is what i'm using to try and capture the data all the way to li class ="myIdd" -->
<button type="button" class="btn toggle-addToSet" name="button" data-setid="{{s._id}}">add Article Id to this Set!</button>
</div>
</div>
</div>
{{/each}}
<!-- end of capture -->
</div>
</div>
</div>
</div>
</div>
</div>
</li>
{{/each}}
</ul>
在我的模板助手中,就像這樣
Template.summeryArticle.events({
'click .toggle-addToSet': function(e, template) {
var ob = this
console.log(ob);
}
});
其中var ob = this
僅捕獲
{{#each set}}
<div class="col s6 m6 addSet teal">
<div class="card ">
<div class="card-image">
<span class="card-title cardSet">{{name}}</span>
</div>
<div class="card-footer">
<!-- This button is what I'm using to try and capture the data all the way to li class ="myIdd" -->
<button type="button" class="btn toggle-addToSet" name="button" data-setid="{{s._id}}">add Article Id to this Set!</button>
</div>
</div>
</div>
{{/each}}
但是正如討論的那樣,我需要它來捕獲整個文檔,即
{{#each categories}}
capture everything in here
{{/each}}
當您調用{{#each set}}...{{/each}}
您正在更改內部塊的上下文。
我建議使用{{#each catSet in set}}...{{/each}}
這不會更改each
塊的上下文,但是會引入新的catSet
變量,如此處所述
在您的情況下:
<ul>
{{#each categories}}
<li class="myIdd">
<div class="row col s12 m7">
<div class="card" id="cardId">
<div class="card-image waves-effect waves-block waves-light">
<a href="/latestSingle/{{_id}}"><img src="{{better_featured_image.source_url}}"></a>
</div>
<div class="card-content">
<h5 class=" truncate grey-text text-darken-4">{{title.rendered}}</h5>
<a href="/latestSingle/{{_id}}">MORE</a> <a href="#modal2" class="modal-trigger waves-effect waves-light" onclick="Materialize.showStaggeredList('#bottom-options')"><i class="waves-effect waves-teal small material-icons right">playlist_add</i></a>{{>
likePartial}}{{> reblogPartial}}
<!-- The modal below is what brings up all the sets the user has created so that the user can pick with set they wat to save the article in -->
<div id="modal2" class="modal bottom-sheet">
<div class="modal-content">
<div class="row">
<!-- data being captured is only below this, but i need it to capture up until li class ="myIdd" -->
{{#each catSet in set}}
<div class="col s6 m6 addSet teal">
<div class="card ">
<div class="card-image">
<span class="card-title cardSet">{{catSet.name}}</span>
</div>
<div class="card-footer">
<!-- This button is what i'm using to try and capture the data all the way to li class ="myIdd" -->
<button type="button" class="btn toggle-addToSet" name="button" data-setid="{{s._id}}">add Article Id to this Set!</button>
</div>
</div>
</div>
{{/each}}
<!-- end of capture -->
</div>
</div>
</div>
</div>
</div>
</div>
</li>
{{/each}}
</ul>
