废话不多说了,直接奉上代码;
代码如下:
var map = new BMap.Map('allmap');
var Bcenter = new BMap.Point(116.404,39.915);
map.centerAndZoom(Bcenter,11);
//自定义控件
function staticControl(){
this.defaultAnchor = BMAP_ANCHOR_TOP_LEFT;
this.defaultOffset = new BMap.Size(10,10);
}
//继承Control的API
staticControl.prototype = new BMap.Control();
//初始化控件
staticControl.prototype.initialize=function(map){
var div = document.createElement('div');
var e1 = document.createElement('input');
e1.type = 'button';
e1.value = '重置';
e1.onclick=function(){
statics();
}
div.appendChild(e1);
var e2=document.createElement('input');
e2.type = 'button';
e2.value = '缩小';
e2.onclick=function(){
endStatics();
}
div.appendChild(e2);
var e3 = document.createElement("input");
e3.type = "button";
e3.value = "放大";
e3.onclick = function () {
setStatics();
}
div.appendChild(e3);
//添加DOM元素到地图中
map.getContainer().appendChild(div);
//返回DOM
return div;
}
//创建控件实例
var staticsCtrl = new staticControl();
//添加到地图当中
map.addControl(staticsCtrl);
function statics(){
map.centerAndZoom(new BMap.Point(116.404,39.915),11);
}
function endStatics(){
map.setZoom(map.getZoom()-2);
}
function setStatics(){
map.setZoom(map.getZoom()+2)
}
