Question

when I use the following line in the console (FF & chrome)

var stripID = "\'#strip_" + ID + "\'";
console.log(stripID);

I get what I wanted: '#strip_126327'
But when I put it in the JS file, and the function executing this, is triggered i get

uncaught exception: Syntax error, unrecognized expression: ''

withut even a file and line reference.

Also, the purpose of all this is to get a string to put in $() selector.

You don’t need the single quotes in there:

var stripID = "#strip_" + ID;
$(stripID).whatever();

is sufficient. ' is not a valid character in a selector.
