锚定标记无法禁用。最简单的方法是使用 ko绑定，然后渲染 span 而不是

 <！ -  ko if：c $ c> anchor  skypeId === null  - > 
< span>无Skype ID< / span> 
<！ -  / ko  - > 
<！ -  ko if：skypeId！== null  - > 
< a id =aQStreamSkypedata-bind =attr：{href：''}，点击：$ parent.StoreUserClick，text：skypeId>< / a> 
<！ -  / ko  - > 

这是一个小提琴

I need to disable the anchor tag inside a foreach loop of knockout.js in HTML.

Here is my code:

<a id="aQStreamSkype" data-bind="attr:{href: ''}, click: $parent.StoreUserClick,disable: ($data.SkypeId == 'null')">Skype </a>

Anchor tags cannot be disabled.
The easiest is to use ko if binding and then render a span instead of the anchor if the skype id is null

<!-- ko if: skypeId === null -->
    <span >No Skype Id</span>
<!-- /ko -->
<!-- ko if: skypeId !== null -->
    <a id="aQStreamSkype" data-bind="attr:{href: ''}, click: $parent.StoreUserClick,text: skypeId"></a>
<!-- /ko -->

Here is a fiddle
