That is, `JSINHTMLENCODE` first encodes someValue with `HTMLENCODE`, and then encodes the result with `JSENCODE`. ## Use `{!JSINHTMLENCODE(text)}` and replace text with the merge field or text string that contains the unsafe JavaScript characters. ## Tips - This function is only available in custom buttons and links, and in Visualforce. ![Merge Field Example](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-platform-extend_click-264-0-0-production-enus/5f7d9219-b7b1-4552-8891-f1aba9b289fc/images/icon_example.png) Merge Field Example If the merge field `foo__c` contains `Enter the user's name`, `{!JSINHTMLENCODE(foo__c)}` results in: `<B>Enter the user's name</b>`
