Encapsulates a sequence of characters meant to be embedded between quotes in a JavaScript expression. Use of this type presents a security risk: the encapsulated content should come from a trusted source, as it will be included verbatim in the template output.
|
|
|
|
Without declaring a variable to be a safe JavaScript string:
|
|
|
|
```go-html-template
|
|
{{ $title := "Lilo & Stitch" }}
|
|
<script>
|
|
const a = "Title: " + {{ $title }};
|
|
</script>
|
|
```
|
|
|
|
Rendered:
|
|
|
|
```html
|
|
<script>
|
|
const a = "Title: " + "Lilo \u0026 Stitch";
|
|
</script>
|
|
```
|
|
|
|
To avoid escaping by Go's [html/template] package:
|
|
|
|
```go-html-template
|
|
{{ $title := "Lilo & Stitch" }}
|
|
<script>
|
|
const a = "Title: " + {{ $title | safeJSStr }};
|
|
</script>
|
|
```
|
|
|
|
Rendered:
|
|
|
|
```html
|
|
<script>
|
|
const a = "Title: " + "Lilo & Stitch";
|
|
</script>
|
|
```
