New line in JavaScript and not PHP?

[Mathy]

I am trying to trigger this code:

 

echo '

var sContent=parent.document.getElementById("cont").value.replace("[\f\n\r\t\v]", "[NL]");

';

 

As you can see, I am trying to make PHP ignore the string within the JavaScript replace function's parameter, so that JavaScript should handle the new lines, and PHP shouldn't. How is this possible?

Try double escaping the slashes, such as \\n.

Didn't work. My current code:

 

                                echo '
			var sContent=parent.document.getElementById("cont").value.replace("[\\f\\n\\r\\t\\v]", "[NL]");
			';

Anyone have any idea of what could be wrong?

If you use escape characters (or whitespace - \n \t \r etc) within single quotes PHP will ignore them. If you use double quotes PHP will parse them eg: \n will give a new line, \t with give a tab.

 

So the code you have provided should be working correctly. Check what your PHP is outputting by viewing the source (right click > View Source). If the output is correct then the problem maybe your javascript.
