如果范围为空,我如何有条件地显示其他内容?
{{range .Users}}
...
{{end}}
如果范围为空,我想显示不同的 HTML block 。
最佳答案
使用{{range pipeline}} T1 {{else}} T0 {{end}}
:
{{range pipeline}} T1 {{else}} T0 {{end}} The value of the pipeline must be an array, slice, map, or channel. If the value of the pipeline has length zero, dot is unaffected and T0 is executed; otherwise, dot is set to the successive elements of the array, slice, or map and T1 is executed.
例子:
{{range .Users}}
...
{{else}}
<p>No users</p>
{{end}}
