Make a safe url

17 Ⅴ 2010

This is a function that makes a string url safe.
Nice for creating friendly urls that are actually friendly.

// Function for making sure text only uses url safe symbols
function makeSafe(thisText, allowSpace){
	var w = "!@#$%^&*()+=[]\\\';,./{}|\":<>?";
	var s = 'abcdefghijklmnopqrstuvwxyz0123456789-_';
	var x = new Array('àáâãäå', 'ç', 'èéêë', 'ìíîï', 'ñ', 'ðóòôõöø', 'ùúûü', 'ýÿ');
	var r = new Array('a', 'c', 'e', 'i', 'n', 'o', 'u', 'y');

	if(allowSpace){
		s = s + ' ';
	}

	thisText = thisText.toLowerCase();
	var newText = new Array();

	for (i = 0; i < thisText.length; i++){
		thisChar = thisText.charAt(i);
		if(w.indexOf(thisChar) == -1){
			if(s.match(''+thisChar+'')){
				newText[i] = thisChar;
			}else{
				for (j = 0; j < x.length; j++){
					if(x[j].match(thisChar)){
						newText[i] = r[j];
					}
				}
			}
		}
	}

	return newText.join('');
}
