Ember.js和jQuery可排序。如何解决变形脚本 [英] Ember.js and jQuery Sortable. How to work around the metamorph scripts
问题描述
< ul id =sort-container>
{{#each content}}
< li> {{title}}< / li>
{{/ each}}
< / ul>
排序工作正常,直到其中一个绑定需要更新。问题是每个< li>
被ember臭名昭着的变态元素< script>
标签包围。查看此图片中生成的实际DOM
有没有一个简单的方式让这两个玩得很好?
是否有强制视图重画的方式?我可以很容易地实现,在排序停用
事件被触发之后。
在我看来,使用Ember.CollectionView可以解决这个问题。所以我试了一下似乎有效: http://jsfiddle.net/8ahjd/
handlebars:
< script type =text / x-车把>
{{view App.JQuerySortableView content = model}}
< a {{action removeItem}}>删除第二项< / a>
< / script>
< script type =text / x-handlebarsdata-template-name ='jquery-sortable-item'>
{{view.content.title}}
< / script>
javascript:
App = Ember.Application.create();
App.ApplicationController = Ember.ArrayController.extend({
removeItem:function(){
this.removeAt(1);
}
} );
App.ApplicationRoute = Ember.Route.extend({
model:function(){
return [
{id:1,title:'Test 1' },
{id:2,title:'Test 2'},
{id:3,title:'Test 3'}
];
}
});
App.JQuerySortableItemView = Ember.View.extend({
templateName:'jquery-sortable-item'
});
App.JQuerySortableView = Ember.CollectionView.extend({
tagName:'ul',
itemViewClass:App.JQuerySortableItemView,
didInsertElement:function (){
this._super();
this。$()。sortable()。disableSelection();
}
});
I have an ember.js app that I would like to use jquery ui's sortable widget on. My view looks like
<ul id="sort-container">
{{#each content}}
<li>{{title}}</li>
{{/each}}
</ul>
Sorting works fine, until one of the bindings needs to update. The problem is that each <li>
gets surrounded by ember's infamous metamorph <script>
tags. See the actual DOM generated in this image
Is there an easy way to make these two play nicely together?
Is there a way to force the view to repaint? I could easily implement that after the sortable deactivate
event is fired.
It seems to me that using Ember.CollectionView, could solve this. So I gave a try. It seems to work: http://jsfiddle.net/8ahjd/
handlebars:
<script type="text/x-handlebars">
{{view App.JQuerySortableView content=model}}
<a {{action removeItem}}>Remove Second Item</a>
</script>
<script type="text/x-handlebars" data-template-name='jquery-sortable-item'>
{{view.content.title}}
</script>
javascript:
App = Ember.Application.create();
App.ApplicationController = Ember.ArrayController.extend({
removeItem: function() {
this.removeAt(1);
}
});
App.ApplicationRoute = Ember.Route.extend({
model: function() {
return [
{id: 1, title:'Test 1'},
{id: 2, title:'Test 2'},
{id: 3, title:'Test 3'}
];
}
});
App.JQuerySortableItemView = Ember.View.extend({
templateName: 'jquery-sortable-item'
});
App.JQuerySortableView = Ember.CollectionView.extend({
tagName: 'ul',
itemViewClass: App.JQuerySortableItemView,
didInsertElement: function(){
this._super();
this.$().sortable().disableSelection();
}
});
