Form submits correctly in Chrome/FF, but fails altogether in IE/Safari

I have a form with a css submit button. When a the submit button is clicked, i call a function that executes:

document.forms["request"].onsubmit();

What should happen, then, is that the onsubmit method ought to be triggered. This works properly in Chrome/FF, but for some reason IE/Safari will bypass the onsubmit function and simply add the parameter "address=" onto the url as if it were submitting the form and ignoring the onsubmit function. Heres the code for the form:

      <form id="request" method="get" onsubmit="addLocation(this.address.value); return false;">
        <br>
        <label style="position:relative;left:5px;" for="address">Enter an intersection or address:
        </label>
        <br>
        <br>
        <input style="height:35px; width:300px;position:relative;bottom:1px;left:10px;" id="address" name="address" class="required address"/>
        <a style="float:right;right:120px;position:relative;" class="button" onclick="submit();">
          <span>Submit Request
          </span>
        </a>
      </form>

and what follows are some relevant js functions:

function addLocation(address) {
    if (geocoder) {
        geocoder.getLocations(address, function (point) {
            if (!point) {
                alert(address + " not found");
            } else {
                if (point.Placemark[0].address != submittedString) {
                    submittedString = point.Placemark[0].address;
                    addRow(point.Placemark[0].address);
                    req = "addrequest?truck=" + "coolhaus&address=" + point.Placemark[0].address;
                    alert(req);
                    addRequest(req);
                    request.onreadystatechange = function () {}
                }
            }
        });
    }
}

function addRequest(req) {
    try {
        request = new XMLHttpRequest();
    } catch (e) {
        try {
            request = new ActiveXObject("Microsoft.XMLHTTP");
        } catch (e) {
            alert("XMLHttpRequest error: " + e);
        }
    }
    request.open("GET", req, true);
    request.send(null);
    return request;
}

Don't name your function "submit", there is already a method in the form with that name, so it can conflict with that.

It's the submit method that you can call to submit the form, not the onsubmit event. So, your code to post the form should be:

document.forms["request"].submit();
