在主页面中的Web内容表单中的谷歌地图

Question

我想在我的网页内容表单(使用母版页)中添加一个简单的谷歌地图,但没有任何显示,我没有收到任何明显的错误

<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="ShelterMap.aspx.cs" Inherits="ShelterExpress.ShelterMap" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> 
<style type="text/css"> 
  #map_canvas { height: 100% } 
</style>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<div id="map_canvas" style="width:100%; height:100%"></div> 

<script type="text/javascript">
    $(document).ready(function() {
        var latlng = new google.maps.LatLng(-34.397, 150.644);
        var myOptions = {
            zoom: 8,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    });
</script>

</asp:Content>

您需要设置宽度和高度明确度,而不是100%.删除<style></style>标记,然后设置<div id="map_canvas" style="width: 300px; height: 300px">

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js "></script>
    <script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=true"></script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <div id="map_canvas" style="width: 300px; height: 300px">
    </div>
    <script type="text/javascript">
        $(document).ready(function () {
            var latlng = new google.maps.LatLng(-34.397, 150.644);
            var myOptions = {
                zoom: 8,
                center: latlng,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
        }); 
    </script>
</asp:Content>
