safe.JS
Syntax
safe.JS INPUT ⟼ template.JS
Alias
safeJS
In this context, safe means the string encapsulates a known safe EcmaScript5 Expression (e.g., (x + y * z())
).
Template authors are responsible for ensuring that typed expressions do not break the intended precedence and that there is no statement/expression ambiguity as when passing an expression like { foo:bar() }\n['foo']()
, which is both a valid expression and a valid program with a very different meaning.
Example: Given hash = "619c16f"
defined in the front matter of your .md
file:
<script>var form_{{ .Params.hash | safeJS }};…</script>
→<script>var form_619c16f;…</script>
<script>var form_{{ .Params.hash }};…</script>
→<script>var form_"619c16f";…</script>
