How to show variable in Golang template inside range












0















I have some code on the server:



...
c.HTML(http.StatusOK, "videos.html", gin.H{
"files": files, //slice
"errMessage": errMessage,
})
...


And I have some code on the client:



...
{{ range .files }}
<tr>
<td>{{.}}</td>
<td><a href="/download?filename={{.}}" style="color:blue;">Download</a></td>
<td><a href="/delete?filename={{.}}" style="color:red;">Delete</a></td>
<td><button id="{{.}}">Посмотреть</button></td>
{{ if .errMessage }} <td style="color:red;">Processing...</td>
{{ else }} <td>Done</td> {{ end }}
</tr>
{{ end }}
...

    $.errMessage. From the docs: " When execution begins, $ is set to the data argument passed to Execute, that is, to the starting value of dot. "

Can you show what is the error message? I deduce that your .errMessage is out of scope inside your {{ range .files }} syntax.



So to fix this problem, you will just declare your .errMessage on top of your {{ range .files }} syntax.



Though its not necessary to declare it on top, the main key here is that you should assign your .errMessage to another variable inside of your template.



It would look something like this ( based on your example ):



...
{{ $errMessage := .errMessage }}

{{ range .files }}
<tr>
<td>{{.}}</td>
<td><a href="/download?filename={{.}}" style="color:blue;">Download</a></td>
<td><a href="/delete?filename={{.}}" style="color:red;">Delete</a></td>
<td><button id="{{.}}">Посмотреть</button></td>
{{ if $errMessage }} <td style="color:red;">Processing...</td>
{{ else }} <td>Done</td> {{ end }}
</tr>
{{ end }}
...


Hope that helps! Cheers!
