为什么'；Javascript是否通过id将值传递给textbox MVC？

我正在尝试将lat和long添加到提供的文本框中。 这似乎是一个问题，因为当我将地址硬编码到变量中时，它返回lat和long，但只要我通过文本框值检索地址，它就不起作用了。为什么

以下是包含代码的视图：

<div class="form-group">
    @Html.LabelFor(model => model.StreetNr, new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.StreetNr)
        @Html.ValidationMessageFor(model => model.StreetNr)
    </div>
</div>

<div class="form-group">
    @Html.LabelFor(model => model.StreetName, new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.StreetName)
        @Html.ValidationMessageFor(model => model.StreetName)
    </div>
</div>

<div class="form-group">
    @Html.LabelFor(model => model.Suburb, new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.Suburb)
        @Html.ValidationMessageFor(model => model.Suburb)
    </div>
</div>

<div class="form-group">
    @Html.LabelFor(model => model.Town, new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.Town)
        @Html.ValidationMessageFor(model => model.Town)
    </div>
</div>

        geocoder.geocode({ 'address': address }, function (results, status) {

            if (status == google.maps.GeocoderStatus.OK) {
                var latitude = results[0].geometry.location.lat();
                var longitude = results[0].geometry.location.lng();
                //alert('Lat' + " " + latitude + " " + 'long' + " " + longitude);
                document.getElementById('EventLat').value = latitude;
                document.getElementById('EventLong').value = longitude;
            }
            else {
                alert("Location not found, Please enter a valid address");
                document.getElementById('StreetNr').value = " ";
                document.getElementById('StreetName').value = " ";
                document.getElementById('Suburb').value = " ";
                document.getElementById('Town').value = " ";
                document.getElementById('ZipCode').value = " ";
            }
        });

控制台日志（地址）

这段简单的代码解决了这个问题

返回的错误是：值“[object HTMLInputElement]”无效

以下是我的问题的解决方案：

        var address1 = document.getElementById("StreetNr").value + " " + document.getElementById("StreetName").value;
        var address2 = document.getElementById("Suburb").value + " " +   document.getElementById("Town").value;
