/*縮放控件type有四種類型:
BMAP_NAVIGATION_CONTROL_SMALL：僅包含平移和縮放按鈕；BMAP_NAVIGATION_CONTROL_PAN:僅包含平移按鈕；BMAP_NAVIGATION_CONTROL_ZOOM：僅包含縮放按鈕*/
//添加控件和比例尺
function add_control(){
map.addControl(top_left_control); // 測距離的
map.addControl(top_left_navigation); // 左導航默認
map.addControl(top_right_navigation); // 右導航平移與縮放

//移除控件和比例尺
function delete_control(){

效果
添加了很實用的導航
