The Set Text Of Container behavior replaces the content and formatting of an existing container (that is, any element that can contain text or other elements) on a page with the content you specify. The content can include any valid HTML source code.
You can embed any valid JavaScript function call, property, global variable, or other expression in the text. To embed a JavaScript expression, place it inside braces ({}). To display a brace, precede it with a backslash (\{).
Example:
The URL for this page is {window.location}, and today is {new Date()}.
