Idea: Pass the latitude value as the parameter to the corresponding parameter value in the Latlon.htm file. Examples are as follows:

Solution One:

1, a total of two pages (Default.aspx and Latlon.htm)

2. Project:

3, default page code:

<%@ Page language= "C #" autoeventwireup= "true" codebehind= "Default.aspx.cs" inherits= "map editor. _default"%>

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">

<title></title>

<script language= "javascript" type= "Text/javascript" >

function Showmap () {

var Long = document.getElementById ("Long"). Value;

var Lat = document.getElementById ("Lat"). Value;

var company = document.getElementById (' company '). Value;

var zoomlevel = 10;

if (long== "" | | lat== "") {

Long = 113.2759952545166;

Lat = 23.117055306224895;

Company = "Guangzhou";

}

var obj = new Object ();

Obj.lat = lat;//Latitude

OBJ.LNG = long;//Longitude

Obj.zoom = Zoomlevel; Zoom level

Obj.ent = Company;

Obj.sdpno = Company;

obj.addr = "Guangdong";

var retVal = window.showModalDialog (

' latlon.htm?_= ' + math.random ()

, obj, ' dialogwidth:800px;dialogheight:450px; '

);

}

</script>

<body>

<form id= "Form1" runat= "Server" >

<div>

<label title= "Enterprise Name" > Enterprise name:</label>

<input type = "Text" id= "Company"/>

<label title= "Longitude" > Longitude:</label>
