Convert string to Title Case with JavaScript

Question

Is there a simple way to convert a string to Title Case? E.g. john smith becomes John Smith. I'm not looking for something complicated like John Resig's solution, just (hopefully) some kind of one- or two-liner.

Answer 1

Try this:

function toTitleCase(str) {   return str.replace(     /\w\S*/g,     function(txt) {       return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();     }   ); }

<form>   Input:   <br /><textarea name="input" onchange="form.output.value=toTitleCase(this.value)" onkeyup="form.output.value=toTitleCase(this.value)"></textarea>   <br />Output:   <br /><textarea name="output" readonly onclick="select(this)"></textarea> </form>
