问题描述
在敲除排序中，我知道您可以在sortable绑定中使用isEnabled禁用可排序列表.我也知道您可以在beforeMove函数中使用cancelDrop禁用移动项.问题是isEnabled禁用了整个列表，并且cancelDrop仅在将项目拖放到另一个sortable上之后才能调用.
In knockout-sortable, I know that you can disable a sortable list using isEnabled in the sortable binding. I also know you can disable moving items using cancelDrop in a beforeMove function. The problem is, isEnabled disables the whole list, and cancelDrop can only be called after the item is already dragged and dropped onto another sortable.
是否可以在某些包含的项目上禁用sortable的点击/拖动行为?
Is there a way to disable sortable's click/drag behavior on certain contained items?
推荐答案
您可以为此目的使用jQuery UI可排序选项items或cancel.此处的文档: http://jqueryui.com/sortable/#items .
You can use the jQuery UI sortable options items or cancel for this purpose. Docs here: http://jqueryui.com/sortable/#items.
您可以将它们添加到绑定中，例如:
You would add them in a binding like:
<div class="container" data-bind="sortable: { data: tasks, options: { cancel: '.prevent' } }">
或全局类似:
ko.bindingHandlers.sortable.options.cancel = ".prevent";
