testJtopo.js 代码(来自官网的demo)：
$(document).ready(function(){
var canvas = document.getElementById('Jtopo');//获取画布
var stage = new JTopo.Stage(canvas);//获取舞台
//显示工具栏
//showJTopoToobar(stage);
var scene = new JTopo.Scene(stage);//把舞台添加到画布
scene.background = '01.png';//画布背景
var node = new JTopo.Node("Hello");//新节点 默认test=hello
node.setLocation(409, 269);//节点位置
scene.add(node);//将节点添加到场景
node.mousedown(function(event){//设置鼠标事件
if(event.button == 2){
node.text = '按下右键';
}else if(event.button == 1){
node.text = '按下中键';
}else if(event.button == 0){
node.text = '按下左键';
}
});
node.mouseup(function(event){
if(event.button == 2){
node.text = '松开右键';
}else if(event.button == 1){
node.text = '松开中键';
}else if(event.button == 0){
node.text = '松开左键';
}
});
node.click(function(event){
console.log("单击");
