Convert to uppercase as user types using javascript

Question

I want to convert lowercase chars to uppercase as the user types using javascript. Any suggestions are welcome.

I have tried the following:

$(\"#text         


        

Answer 1

function changeToUpperCase(event,obj) {
    charValue = (document.all) ? event.keyCode : event.which;
    if (charValue!="8" && charValue!="0" && charValue != "27"){
        obj.value += String.fromCharCode(charValue).toUpperCase();
        return false;
    }else{
        return true;
    }
}

Edit:

The most simplest way is by using css:

#txtId {text-transform:uppercase}
