淘汰赛JS-如果在foreach中绑定

Question

Not sure what I am doing wrong but here is my code.

<ul data-bind="foreach: publications" >
   <!-- ko if: mediatype === '2' -->
   <li data-bind="text: mediatype, value: id"></li>
   <!-- /ko -->
</ul>

This is returning the whole list in the foreach (all mediatype numbers)

I also tried this:

<ul data-bind="foreach: publications" >
  <li data-bind="if: mediatype === '2', text: mediatype, value: id"></li>
</ul>

This returns nothing. Not sure what is wrong here?

Answer 1

对于诸如if的表达式：mediatype ==='2'，则需要使用方括号，即if：mediatype（）==='2'
