Escaping a character in HTML value param

I have a TextArea in my jelly file. I would like to have something like '${JOB_NAME}' for its value. But when I do that it checks for the environment variable "JOB_NAME". I just want to escape ${ and } so that it will display it as it is without trying to interpret it.

<f:textarea name = "script"  value = "${JOB_NAME}">

How would I do that?

Solution

  • Use $${JOB_NAME} to prevent $ from being interpolated.
