## Slices
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ $s := slice "foo" "bar" "baz" }}
|
||
|
{{ range $s }}
|
||
|
<p>{{ . }}</p>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
Result:
|
||
|
|
||

```html
|
||

<p>foo</p>
|
||
|
<p>bar</p>
|
||
|
<p>baz</p>
|
||
|
```
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ $s := slice "foo" "bar" "baz" }}
|
||
|
{{ range $v := $s }}
|
||
|
<p>{{ $v }}</p>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||

Result:
|
||
|
|

<p>foo</p>
|
||
|
<p>bar</p>
|
||
|
<p>baz</p>
|
||
|
```
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ $s := slice "foo" "bar" "baz" }}
|
||
|
{{ range $k, $v := $s }}
|
||
|
<p>{{ $k }}: {{ $v }}</p>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
Result:
|
||
|
|
||
|
```html
|
||
|

|
||
|
<p>1: bar</p>
|
||
|
<p>2: baz</p>
|
||
|
```
|
||
|
|
||
|
## Maps
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ $m := slice
|
||
|
(dict "name" "John" "age" 30)
|
||
|
(dict "name" "Will" "age" 28)
|
||
|
(dict "name" "Joey" "age" 24)
|
||
|
}}
|
||
|
{{ range $m }}
|
||
|
<p>{{ .name }} is {{ .age }}</p>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
Result:
|
||
|
|
||

|
||
|
<p>John is 30</p>
|
||
|
<p>Will is 28</p>
|
||
|
<p>Joey is 24</p>
|
||
|
```
|
||
|
|
||
|
## Page collections
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ range where site.RegularPages "Type" "articles" }}
|
||
|
<h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
Result:
|
||
|
|
||
|
```html
|
||
|
<h2><a href="/articles/article-3/">Article 3</a></h2>
|
||
|
<h2><a href="/articles/article-2/">Article 2</a></h2>
|
||
|
<h2><a href="/articles/article-1/">Article 1</a></h2>
|
||
|
```
|
||
|
|
||
|
## Break
|
||
|
|
||
|
Use the `break` statement to stop the innermost iteration and bypass all remaining iterations.
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ $s := slice "foo" "bar" "baz" }}
|
||
|
{{ range $s }}
|
||
|
{{ if eq . "bar" }}
|
||
|
{{ break }}
|
||
|
{{ end }}
|
||
|
<p>{{ . }}</p>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
Result:
|
||
|
|
||
|
```html
|
||
|
<p>foo</p>
|
||
|
```
|
||
|
|
||
|
## Continue
|
||
|
|
||
|
Use the `continue` statement to stop the innermost iteration and continue to the next iteration.
|
||
|
|
||
|
Template:
|
||
|
|
||
|
```go-html-template
|
||
|
{{ $s := slice "foo" "bar" "baz" }}
|
||
|
{{ range $s }}
|
||
|
{{ if eq . "bar" }}
|
||
|
{{ continue }}
|
||
|
{{ end }}
|
||
|
<p>{{ . }}</p>
|
||
|
{{ end }}
|
||
|
```
|
||
|
|
||
|
Result:
|
||
|
|
||
|
```html
|
||
|
