DIV onload不会触发JavaScript方法

Question

我正在使用ASP.NET MVC 4,我有一个像这样的DIV:

<div id="map_canvas" style="width: 500px; height: 400px;" onload="mapAddress();"></div>

然后,在JavaScript文件中(我已验证已加载)是mapAddress函数:

function mapAddress() {
    //In this case it gets the address from an element on the page, but obviously you  could just pass it to the method instead
    var address = $("#Address").val();

    geocoder.geocode({ 'address': address }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            var myLatLng = results[0].geometry.location.LatLng;

            var mapOptions = {
                center: myLatLng,
                zoom: 15,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };

            var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

            var marker = new google.maps.Marker({
                position: myLatLng,
                map: map,
                title: $("#Name").val() + " Location"
            });
        }
        else {
            alert("The location of the event could not be mapped because: " + status);
        }
    });
}

但无论出于什么原因,它都没有被召集.我误解了这onload件事吗？

谢谢大家!

onload 不会开火 <div>元素.

您可以在document或body之后立即调用脚本,或者不太理想的方式执行此操作<div>.

<div id="map_canvas" style="width: 500px; height: 400px;"></div>
<script>
 mapAddress();
</script>
