<body><h1 id="myHeader" onclick="getValue()" value = "good">This is a header</h1>
<p>Click on the header to alert its value</p></body>
</html>就是 通过$("#myHeader")把 <h1 id="myHeader" onclick="getValue()" value = "good">This is a header</h1>里面的“This is a header” 取出来 应该怎么写呢？

正解，如果要设置的话，直接$("#myHeader").text('你要设置的内容')就行了。
alert($("#myHeader").html());
alert($("#myHeader").text());
