推荐答案

您可以使用2个受保护的变量.并将纬度和经度保存到该变量中.您可以在Java脚本的客户端获取该值.

Hi,

You can take 2 protected variable. And save latitude and longitude into that variable. You can get that value on the client side in java script.

var xyz = '<%= variable %>';

谢谢，

在Google地图中，您需要设置数据集中的值(纬度，经度)以在客户端(javascript)中可用.

您已经完成了填充部分，并获取了数据集中的值.

要在客户端获取值，
您可以创建两个隐藏字段，使其成为runat ="server"

In google map, you need to set the values(lat,long) from dataset to be available in your client side (javascript).

You have already done the populate part and get the values in dataset.

To get the values in client side,
you can create two hidden fields make it runat="server"

<input type="hidden" id="hdnLat" runat="server" />
<input type="hidden" id="hdnLong" runat="server" />

//Create a variable that can access the server side control
var objLat = docuent.getElementById("<%= hdnLat.ClientID %>");
var objLat = docuent.getElementById("<%= hdnLong.ClientID %>");

现在，在页面加载背后的代码中，使用数据集获取lat和Long值，并将其分配给上述两个变量.

Now in code behind page load, use the dataset to get the lat and Long value and assign it in the above two variable.

hdnLat.Value = {value from dataset};
hdnLong.Value = {value from dataset};

现在，您可以使用javascript在Google地图创建例程中使用值
objLat.value和objLong.value.

这应该起作用.

欢呼

In your google map creation routine in javascript, you can now use the value
objLat.value and objLong.value.

This should work.

cheers
