我试图根据我在下拉字段中选择的内容动态更改区域。
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?region=DK"></script>

有人可以帮我解决这个问题吗?
您可以在页面加载后动态加载 JavaScript,但请记住:一旦加载,就无法在活动页面中卸载 JavaScript。它存储在浏览器内存池中。您可以重新加载页面,这将清除活动脚本,然后重新开始。或者,您可以覆盖已设置的功能。
如此说来。以下是如何在页面加载后使用 javascript 更改脚本:
<select onChange="changeRegion(this.value);">
<option value="-">Select region</option>
<option value="SE">Sweden</option>
<option value="DK">Denmark</option>
</select>
<div id="output">
<script id="map" type="text/javascript" src="https://maps.googleapis.com/maps/api/js?region=DK"></script>
</div>
<script type="text/javascript">
function changeRegion(value)
{
var s = document.createElement("script");
s.type = "text/javascript";
s.src = "https://maps.googleapis.com/maps/api/js?region=" + value;
s.innerHTML = null;
s.id = "map";
document.getElementById("output").innerHTML = "";
document.getElementById("output").appendChild(s);
}
</script>
