我创建了一个新的 Web 应用程序，并删除了所有服务器控件。然后我从此页面实现了谷歌地图和搜索框: https://developers.google.com/maps/documentation/javascript/examples/places-searchbox
实际上只是复制粘贴代码。
一切都像 Google 示例一样工作正常，但问题是，当我搜索并按 Enter 时，页面会发回，从而将页面重新加载为新页面。我无法找出触发重新加载页面的原因。

最佳答案
要覆盖默认行为，您需要指定一个默认按钮。
在母版页中修改表单标记，如下所示:
<form runat="server" defaultbutton="btnDisableEnter">
并将相应的按钮添加到母版页的底部:
<asp:Button ID="btnDisableEnter" runat="server" Text="" OnClientClick="return false;" style="display:none;" />
