jQuery Title Case

Question

Is there a built in way with jQuery to \"title case\" a string? So given something like bob smith, it turns into \"Bob Smith\"?

Answer 1

I have modified rBizzle's code slightly. I don't want to mess with the McClouds and McIntosh's of the world (I'm listening to Celtic music right now!), so I added a condition to only modify if ALL CAPS or ALL lowercase:

function isUpperCase(str) {
    return str === str.toUpperCase();
}

function isLowerCase(str) {
    return str === str.toLowerCase();
}

function toProperCase(str) {
	//only mess with it if it is all lower or upper case letters
	if (isUpperCase(str) || isLowerCase(str)){
	 	var lcStr = str.toLowerCase();
    	return lcStr.replace(/(?:^|\s)\w/g, function(match) {
       	 	return match.toUpperCase();
    	});	
	} else {
		return str;
	}
}

I am mostly trying to contend with the users WHO INSIST ON YELLING THEIR DATA ENTRY! It's one thing for internal data, but when customers are going to see it, I have to draw the line.
