I have a form. I have made it so that if your name is not put in, a red border is put on the name field. That works, BUT...it's for a split second, and then the page reloads. I want the red border to appear, and then stay there. For some reason it's for a split second. Can someone help me make it so the page doesn't reload after displaying the red border?

Here's the script.

window.onload = function() {

    document.getElementById("Hogwarts").onsubmit = function () 
    {

        window.alert("Form submitted. Owl being sent...");
        var fname = document.getElementById("fName");

        if(!fName.value.match("^[A-Z][A-Za-z]+( [A-Z][A-Za-z]*)*$"))
        {
            window.alert("You must enter your name.");
            addClass(fName, "errorDisp");
            document.getElementById("fName").focus();
        }
        else
            return true;
        }   
    }

    function addClass(element, classToAdd) 
        {
            var currentClassValue = element.className;

            if (currentClassValue.indexOf(classToAdd) == -1) {
                if ((currentClassValue == null) || (currentClassValue === "")) {
                    element.className = classToAdd;
                } else {
                    element.className += " " + classToAdd;
                }
            }
       }

      function removeClass(element, classToRemove) 
      {
        var currentClassValue = element.className;

        if (currentClassValue == classToRemove) {
            element.className = "";
            return;
        }

        var classValues = currentClassValue.split(" ");
        var filteredList = [];

        for (var i = 0 ; i < classValues.length; i++) {
            if (classToRemove != classValues[i]) {
                filteredList.push(classValues[i]);
            }
        }

        element.className = filteredList.join(" ");
      }

Here's the HTML.
