javascript - DIV onload 不触发 JavaScript 方法

Question

我正在使用 ASP.NET MVC 4 并且我有一个像这样的 DIV:

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

然后，在一个 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);
        }
    });
}

但无论出于何种原因，它都没有被调用。我是否误解了 onload 事件？

谢谢大家!

onload不会为 <div> 触发元素。

您可以为 document 执行此操作或 body ，或者在 <div> 之后立即调用脚本的不太理想的方式.

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