[javascript]google map api 与jquery结合使用(1)
打开信息浮窗
修改javascript代码:
map.js
$(document).ready(function()


{

if (GBrowserIsCompatible())
{
var map = new GMap2(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
//开启滚轮伸缩效果--鼠标滚轮向前滚放大地图,反之缩小
map.enableScrollWheelZoom();
map.setCenter(new GLatLng(36.94,106.08),4);
//打开信息浮窗--需要在设置地图中心点后进行
map.openInfoWindow(map.getCenter(),document.createTextNode("你好,中国"));

$(window).unload(function ()
{
$('.').unbind();
GUnload();
});
}else

{
alert('你使用的浏览器不支持 Google Map!');
}
});
在地图的中央会显示信息浮窗(相对粗糙)
信息浮窗效果图
地图标注
map.js
$(document).ready(function()


{

if (GBrowserIsCompatible())
{
var map = new GMap2(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
//开启滚轮伸缩效果--鼠标滚轮向前滚放大地图,反之缩小
map.enableScrollWheelZoom();
map.setCenter(new GLatLng(36.94,106.08),4);
//在地图上添加10个位置随机的标记
var bounds = map.getBounds();
var southWest = bounds.getSouthWest();
var northEast = bounds.getNorthEast();
var lngSpan = northEast.lng() - southWest.lng();
var latSpan = northEast.lat() - southWest.lat();

for (var i = 0; i < 10; i++)
{
var point = new GLatLng(southWest.lat() + latSpan * Math.random(),
southWest.lng() + lngSpan * Math.random());
map.addOverlay(new GMarker(point));
}
//随机取五个点连成折线,5个点按照经度排序防止折线自身交叉.
var points = [];

for (var i = 0; i < 5; i++)
{
points.push(new GLatLng(southWest.lat() + latSpan * Math.random(),
southWest.lng() + lngSpan * Math.random()));
}

points.sort(function(p1, p2)
{
return p1.lng() - p2.lng();
});
map.addOverlay(new GPolyline(points));
//单击事件句柄

GEvent.addListener(map, "click", function(marker, point)
{

if (marker)
{
map.removeOverlay(marker);

} else
{
map.addOverlay(new GMarker(point));
}
});

$(window).unload(function ()
{
$('.').unbind();
GUnload();
});
}else

{
alert('你使用的浏览器不支持 Google Map!');
}
});
此时可以在地图中看到10个标注和一条折线,由于是随机生成的,所以位置不是固定。

在标记上显示信息浮窗
map.js
$(document).ready(function()


{

if (GBrowserIsCompatible())
{
var map = new GMap2(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
//开启滚轮伸缩效果--鼠标滚轮向前滚放大地图,反之缩小
map.enableScrollWheelZoom();
map.setCenter(new GLatLng(36.94,106.08),4);
//在指定点以指定标签创建标记

function createMarker(point, number)
{
var marker = new GMarker(point);

GEvent.addListener(marker, "click", function()
{
marker.openInfoWindowHtml("Marker #<b>" + number + "</b>");
});
return marker;
}
//添加10个位置随机的标记
var bounds = map.getBounds();
var southWest = bounds.getSouthWest();
var northEast = bounds.getNorthEast();
var lngSpan = northEast.lng() - southWest.lng();
var latSpan = northEast.lat() - southWest.lat();

for (var i = 0; i < 10; i++)
{
var point = new GLatLng(southWest.lat() + latSpan * Math.random(),
southWest.lng() + lngSpan * Math.random());
map.addOverlay(createMarker(point, i + 1));
}

$(window).unload(function ()
{
$('.').unbind();
GUnload();
});
}else

{
alert('你使用的浏览器不支持 Google Map!');
}
});
在标记上面显示信息浮窗的效果
分标签的信息浮窗
map.js
$(document).ready(function()


{

if (GBrowserIsCompatible())
{
var map = new GMap2(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
//开启滚轮伸缩效果--鼠标滚轮向前滚放大地图,反之缩小
map.enableScrollWheelZoom();
map.setCenter(new GLatLng(36.94,106.08),4);
//信息浮窗内容
var infoTabs = [
new GInfoWindowTab("气候", "华北地区气候不错"),
new GInfoWindowTab("天气", "冷空气南下,可能降雪。")
];
//在地图的中心添加一个标记并自动打开其信息浮窗
var marker = new GMarker(map.getCenter());

GEvent.addListener(marker, "click", function()
{
marker.openInfoWindowTabsHtml(infoTabs);
});
map.addOverlay(marker);
marker.openInfoWindowTabsHtml(infoTabs);

$(window).unload(function ()
{
$('.').unbind();
GUnload();
});
}else

{
alert('你使用的浏览器不支持 Google Map!');
}
});
此时的浮窗是分标签的
