好的，所以我的问题是我有一个用于显示 googlemaps 的 iframe
iframe 的 src 将设置为使用从数据库中读取的地址作为位置插入到 googlemaps
目前框架只是纯白色，甚至没有出现图片，但是如果将 src 路径放入浏览器 URL 中它工作正常，我拥有的测试 url 是“http://maps.google.com/maps/api /staticmap?markers=27+Landseer+Street,+Belfast&size=500x300&sensor=false"
这是有效的，因为您将看到如果您输入地址栏。
我的目标是让三个框架都单独命名，然后在它们上设置 src。到目前为止，这是我的代码
VB.NET公共类关于继承System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Session("recentAddressmap1") = ""
Session("recentAddressmap2") = ""
Session("recentAddressmap3") = ""
Session("src1") = ""
Session("src2") = ""
Session("src3") = ""
Dim recentCount As Integer
recentCount = 0
Dim addresstest As String = "27 Landseer Street"
Dim words As String() = addresstest.Split(New Char() {" "c})
' Use For Each loop over words and display them
Dim word As String
Dim newaddress As String = ""
Dim loopcounter As Integer = 0
For Each word In words
If loopcounter = 0 Then
newaddress = word
loopcounter = loopcounter + 1
Else
newaddress = newaddress & "+" & word
End If
Next
'''''''''''''''''''''''''''''''''''''''''' DO ENTRY RECENT 1 '''''''''''''''''''''''''''''''''''''''''''''''''''
Session("recentAddressmap1") = newaddress & ",Belfast"
Session("src1") = "http://maps.google.com/maps/api/staticmap?markers=" & Session("recentAddressmap1") & "&size=500x300&sensor=false"
'MsgBox(Session("src1"))
visualAddress1.Attributes.Add("src", Session("src1"))
End Sub
结束类
