Is it possible to restrict users to enter things in in Title Case and not ALL CAPS?

Is there a Javascript to control this?

I want to prevent users from entering info all in lower case or ALL CAPS!

Actually one can do that apparently. Give this a try, same deal as before, put into the code box, and you have to provide it with each field you want the specialness on. Let me know if it works.

<script type="text/javascript">
function toTitleCase(str)
{
//http://efficienttips.com/convert-string-title-case-javascript/
return str.replace(/\w\S*/g, function(txt){return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();});
}
function addTitle(source)
{
if(!(document.querySelector)){base2.DOM.bind(document);}
document.addEventListener('DOMContentLoaded',
function(){
document.querySelector("#"+source).addEventListener("keypress",function(){this.value=toTitleCase(this.value);},false);
}
}

addTitle(MyFieldID);
</script>

whoops, yup (I think you need quotes though)

addTitle("tfa_FirstName");

There are a parenthesis and semicolon missing from the code above --- I got it to work as follows:

<script type="text/javascript">
function toTitleCase(str) {
return str.replace(/\w\S*/g, function(txt){return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();});
}

function addTitle(source) {
if(!(document.querySelector)){base2.DOM.bind(document);}
document.addEventListener('DOMContentLoaded',
function(){
document.querySelector('#'+source).addEventListener('blur',function(){this.value=toTitleCase(this.value);},false);
});
}

addTitle('tfa_Firstname');
</script>
