ASP.NETJSP_点击地图div上的按钮实现对地图数据的入库操作，在地图div上添加一个按钮，单
text-decoration: none;
color: #000;
objDrag = this;//objDrag为拖动的对象
color: #FF0000;
/*--------当不需要实现此功能时，可以将这一部分代码删除------------*/
}
);
left:40px;
#popDiv {
{
121.120606, 28.169589,
objDiv.style.visibility = "hidden";
{
</div>
map.addControl(new OpenLayers.Control.LayerSwitcher());
}
//objDiv.style.opacity = 0.5;//当鼠标按下后透明度改变
//objDiv.style.display = "block";
<div><!--弹出层-->
</body>
//县界
var bounds = new OpenLayers.Bounds(
layers: 'WenLing:biandianzhan_point',
isBaseLayer:true,//设置本层为基底图层
//minScale:xxx , //只有达到一定缩放比例该图层时才显示
format: format
}
}
layers: 'WenLing:dao_region',
map.addControl(new OpenLayers.Control.PanZoomBar({
}
yx : {'EPSG:4326' : true}
layers: 'WenLing:guangxianwang_polyline',
objDiv.style.top = objDiv.offsetTop + "px";
在浏览器输入：:8080/myapp/mytestMap.html
var objDiv = document.getElementById("popDiv");
var tielu = new OpenLayers.Layer.WMS(
mouseD = false;//左键松开
#popTitle .title_right a {
{
{
mx = evnt.clientX;
"http://localhost:8080/geoserver/WenLing/wms",
document.onmouseup = function() {
//objDiv.style.opacity = 1;//当鼠标左键松开后透明度改变
transparent:true,
</head>
mytest_map.jsp的代码如下：
<form action="insert_map.jsp" method="post">
function hidePopup() {//关闭层
objDiv.setCapture();
} else {
#operator {
opacity:0.5
},
"http://localhost:8080/geoserver/WenLing/wms",
再次在浏览器中访问地图页面，可以看到地图上已经多出了刚刚添加的那个点，如下图：
var isIE = document.all ? true : false;//判断浏览器类型
#map {
</div>
transitionEffect:"resize", //使该图层放大或缩小时产生调整大小的动画
//铁路
maxResolution: 0.0013726171875,
opacity:0.5
z-index:4000;
);
);
{
map = new OpenLayers.Map('map', options);
{
<meta charset='utf-8' />
map.addControl(new OpenLayers.Control.Scale($('scale')));
map.zoomToMaxExtent();
border: 2px solid #AEBBCA;
window.captureEvents(Event.MOUSEMOVE);//捕获鼠标拖动事件
},
{
后续需要做的工作有：
var evnt = evnt ? evnt : event;
float: left;
z-index: 3000;
objDrag = "";
if (mouseD == true && objDrag) {
}
objDiv.style.height = "220px";//设置弹出层的高度
}
},
format: format
}
objDiv.style.visibility = "visible";
"水系", "http://localhost:8080/geoserver/WenLing/wms",
position: absolute;
} else {
var evnt = evnt ? evnt : event;
经 度 :<input type="text" value="121." /> </br>
border: 1px solid black;
layers: 'WenLing:shuixi_region',
if (evnt.button == (document.all ? 1 : 0)) {
);
visibility: hidden;
objDiv.style.left = "200px";//设置弹出层距离左边界的距离
}
transparent:true,
<html lang='zh-cn' xmlns="http://www.w3.org/1999/xhtml">
}
units: 'degrees'
if (evnt.button == (document.all ? 1 : 0)) {
map.addControl(new OpenLayers.Control.Navigation());
//objDiv.filters.alpha.opacity = 100;//当鼠标左键松开后透明度改变
position: absolute;
2，完善delete功能、修改功能
},
<script type="text/javascript">
<div>
#popTitle {
},
}
电压等级 :<input type="text" value="110kv" /> </br>
map.addLayers([baselayer, xianjie, waters, islands, tielu, xian, biandianzhan, guangxianwang]);
//minScale:xxx , //只有达到一定缩放比例该图层时才显示
}
//县
opacity:0.5 //设置客户端图层半透明
<div><!--按钮所在div-->
mx = evnt.clientX;
"县", "http://localhost:8080/geoserver/WenLing/wms",
//岛屿
padding: 2px;
</div>
var xianjie = new OpenLayers.Layer.WMS(
<title>My OpenLayers Map</title>
cursor: move;
opacity:0.5
}
background: #9DACBF;
//objDiv.filters.alpha.opacity = 50;//当鼠标按下后透明度改变
至此，基本操作算是完成。
</script>
{
var objDiv = document.getElementById("popDiv");
}
},
);
format: format
var evnt = evnt ? evnt : event;
}
}
format = 'image/png';
var waters = new OpenLayers.Layer.WMS(

objDiv.style.top = parseInt(objDiv.style.top) + mry + "px";
}
//水系

在地图div上添加一个按钮，单击按钮后弹出一个弹出层，在弹出层的输入框内输入数据后点击提交按钮将数据提交至数据库。

);
objDiv.style.left = parseInt(objDiv.style.left) + mrx + "px";
padding-left: 15px;
</html>
if (isIE) {
var mry = evnt.clientY - my;

在输入框中输入测试数据，点击提交，将会提交至insert_map.jsp页面，并在insert_map.jsp页面上显示出数据库中所有的点（包括刚刚添加的这个点），效果如下图：
</div>
"岛", "http://localhost:8080/geoserver/WenLing/wms",
复制代码 代码如下:
guangxianwang = new OpenLayers.Layer.WMS(
if (isIE) {
opacity:1 //设置客户端图层不透明
<link type="text/css" href="https://www.xp.cn/openlayers/theme/default/style.css"/>
访问到mytestMap.jsp页面，单击左上角的“操作”按钮，结果如下：
}
my = evnt.clientY;
layers: 'WenLing:xian_point',
}
{
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
</div>
</form>
}
maxExtent: bounds,
121.871688, 28.525587
<a href="#">关闭</a> </span>
transparent:true, //设置从服务器返回的地图图像是透明的
map.setCenter(map.getCenter());//设置地图中心点
名 称 :<input type="text" value="aaa" /> </br>
overflow: hidden;
<body>
}
3，点击“操作”按钮后可以选择添加、删除或修改。position: new OpenLayers.Pixel(2, 15)
}
function init() {
text-decoration: underline;
}
1，使点击提交后仍然显示在当前页面，且对地图进行刷新。

width: 1000px;
{
objDiv.onmousedown = function(evnt) {
<p>
//基础图层，可以用一个图层组做基础图层

#popTitle .title_right a:hover {
function showPopup() {//弹出层

);
