在PHTML文件中使用Go .Variable内部范围块

Question

I have a .thtml file:

...
<div>
    <p>{{.Something}}</p>        <!-- It works here! -->
    {{range ...}}
        <p>{{.Something}}</p>    <!-- It DOESN't work here! -->
    {{end}}
</div>
...

If I use the value of .Something inside the .thtml file it works fine, but it doesn't work if it is used in the same way inside a {{range ...}} block.

How can I use it?

Answer 1

The cursor is modified by {{range}}. Assign the cursor to a variable and use that variable inside the range.

...
<div>
    <p>{{.Something}}</p>        
    {{$x := .}}    <!-- assign cursor to variable $x -->
    {{range ...}}
        <p>{{$x.Something}}</p>    
    {{end}}
</div>
...

playground example

If the starting cursor in this snippet is the starting value of the template, then use the $ variable:

...
<div>
    <p>{{$.Something}}</p>     <!-- the variable $ is the starting value for the template -->    
    {{range ...}}
        <p>{{$.Something}}</p>    
    {{end}}
</div>
