I want to convert a java variable(containing newline and other special characters) from server side sent to JSP to javascript variable.
In my JSP,
var test = '${educationDescription}';
alert(test);
Value of educationDescription sent from server side is
This is
test
containing newline
and other special chars like " & ; etc
But I am getting javascript error for the above code snippet.
This issue I faced long back and very irritated with javascript as well for no proper error message.
Later I managed to solve by replacing all catridges like below from Java string.
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
'${fn.replace(educationDescription,"\\r\\n|\\r|\\n", "")';
It solves the issue.
The issue here is with, we assume the problem is with new line. But sometimes the String comes with a brand new catride \r which many people not aware.
You can do something like this. Use two slashes ("\\n")
<%
String s = "This is a \\n test";
request.setAttribute("s", s);
%>
var s="${s}";
alert(s);
