Escape a JavaScript string in Play 2.0 view?

Question

Is there an easy way to escape a string to be used as a JavaScript string in a view in Play 2.0? For example, here's a simple view that creates a link with a confirm box in onclick:

@(text:String,link:Call,message:String)
<a href="@link" onclick="return confirm('@message');">@text</a>

That will fail if there are newlines or single quotes in message. What's the best way to do this?

Answer 1

You can use Apache Commons Lang:

@(text:String, link:Call, message:String)

@import org.apache.commons.lang3.StringEscapeUtils.escapeEcmaScript
<a href="@link" onclick="return confirm('@escapeEcmaScript(message)');">@text</a>

You can avoid the explicit import in the template by adding it to your project/Build.scala file:

templatesImport += "org.apache.commons.lang3.StringEscapeUtils.escapeEcmaScript"
