點(diǎn)評(píng)：在Canvas上繪制的東西是不能相應(yīng)鼠標(biāo)事件的，但是使用jTopo添加事件非常簡(jiǎn)單，下面有個(gè)示例，大家可以參考下

復(fù)制代碼

var node = new JTopo.Node("Hello");
node.setLocation(409, 269);
node.mousedown(function(event){
if(event.button == 2){
node.text = '按下右鍵';
}else if(event.button == 1){
node.text = '按下中鍵';
}else if(event.button == 0){
node.text = '按下左鍵';
}
});
node.mouseup(function(event){
if(event.button == 2){
node.text = '松開(kāi)右鍵';
}else if(event.button == 1){
node.text = '松開(kāi)中鍵';
}else if(event.button == 0){
node.text = '松開(kāi)左鍵';
}
});
node.click(function(event){
console.log("單擊");
});
node.dbclick(function(event){
console.log("雙擊");
});
node.mousedrag(function(event){
console.log("拖拽");
});
node.mouseover(function(event){
console.log("mouseover");
});
node.mousemove(function(event){
console.log("mousemove");
});
node.mouseout(function(event){
console.log("mouseout");
});
