为什么会出现 [object HTMLParagraphElement]
代码:function hiddentext()
{
var mychar = document.getElementById("con");
document.write(mychar).style.display="none";
}
function showtext(){
var mychar = document.getElementById("con");
document.write(mychar).style.display="block";
}
</script>
</head>
<body>
<h1>JavaScript</h1>
<p id="con">做为一个Web开发师来说,如果你想提供漂亮的网页、令用户满意的上网体验,JavaScript是必不可少的工具。</p>
<form>
<input type="button" onclick="hiddentext()" value="隐藏内容" />
<input type="button" onclick="showtext()" value="显示内容" />
</form>
</body>
