escape single quote javascript sanitize clean encode

found here http://stackoverflow.com/questions/2195568/how-do-i-add-slashes-to-a-string-in-javascript after searching for the solution:

str = str.replace(/'/g, "\\'")

But I went ahead and improved the concept with a simple function:

function backslash(str){
var str = encodeURIComponent(str.replace(/'/g, "\\'"));
return str;
}

Named it backslash for simplicity but it actually will clean up # $ % ^ &() and anything else like single quote ' and doble quote (normally worked already)

Now you just plug this in where you need to clear up, i.e.:

var note = window.document.ordrfrm.note.value;
..."&note="+backslash(note);

or simpler

var note = backslash(window.document.ordrfrm.note.value);

Which ever will work even with getElementById and now it's easy to play with the note, user input taken like a champ nothing is screwed up when encounters strange characters (strange for javascript at least)!

hope it helps someone, if you like it or have questions post a comment.
