好開心學會了事件代理
var list=getDom('list');//獲取id元素
list.onclick= function (e) {
var e=e || event;
var el= e.srcElement || e.target;
switch (el.className){
case 'close':
removeNode(el);
break;
}
};
//刪除
function removeNode(node){
node.parentNode.remove()
}
function vote(e){
var newtotal=parseInt(document.getElementById('total').innerText);
newtotal+=1;
document.getElementById('total').innerText=newtotal
