Question

trying to put a file path in javascript. it is a pain
\ is an escape character and it always kill the character after the backslash

what i am doing is this
i am trying to add the file path from a jsp view object attribute

window.open("file"+<c:out value="${filePath}" />+fileName); 

but if there are backslash in the end of filePath, it kills the following quotation mark

what is the most efficient workaround. do i have to change the java attribute notation (which i dont want to) or get a script to do it ?

Use / instead of \. The / works fine in Windows as well. You can use fn:replace() to replace it.

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
window.open("file${fn:replace(filePath, '\\', '/')}" + fileName); 

Note that I also fixed the “string concatenation”. Concatenating c:out in Javascript style makes no sense.
