I am writing a web app using AngularJS. The user submits up to 3 keywords to the server. I would like to show commas in between the keywords only if there are enough keywords.
For example:
if there are no keywords, then:
if there is 1 keyword, then: keyword
if there are 2 keywords, then: keyword, keyword
if there are 3 keywords, then: keyword, keyword, keyword
I have the following code:
<tr>
<td>Keywords: </td>
<td>{{post.Keyword1}} <span ng-show = "{{post.Keyword2}}">,</span> {{post.Keyword2}} <span ng-show = "{{post.Keyword3}}">,</span> {{post.Keyword3}}</td>
</tr>
Why does this not work?
Change it to
<td>{{post.Keyword1}} <span ng-show = "post.Keyword2">,</span> {{post.Keyword2}} <span ng-show = "post.Keyword3">,</span> {{post.Keyword3}}</td>
