<script>
var ele = document.createElement('div');
var txt = document.createTextNode('textContent');
ele.appendChild(txt);
document.getElementsByTagName('body')[0].appendChild(ele); //console中运行没有问题,执行这段语句的时候就报错
</script>
</head>
<body>
</body>
</html>
报错是出在 document.getElementsByTagName('body')[0]appendChild(ele)
这句话,
显示错误:Uncaught TypeError: Cannot read property 'appendChild' of undefined
新手,找了半天不知到错在哪了,求解答。谢谢各位 !
