c# - javascript google Places 在 html 中工作，但在 asp 内容中不起作用

Question

我正在尝试使用 javascript 示例，使用 google place api 自动填充一些地址字段。它按计划在 html 中工作，但如果我想在标签内使用它，它就不起作用。我在 Firefox 中没有看到任何 js 错误。我认为我没有正确调用 javascrip。非常感谢您的帮助。我的asp页面、js文件和site.master的代码如下:

test.aspx asp头

<%@ Page Language="C#" AutoEventWireup="true" MasterPageFile="~/Site.Master" CodeBehind="test.aspx.cs" Inherits="Project.test" %>

test.aspx页面

<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent" onload="javascript:initialize()">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>

          </td>
          <td>
            <asp:TextBox id="autocomplete" type="text" runat="server" placeholder="Enter your address" onFocus="javascript:geolocate()"></asp:TextBox>
