<script src="../jquery-2.1.1.js"></script>
<script>
/*$(function(){
alert("asdfghjk");
});*/

/*window.onload = function(){
var myP = document.getElementById("myP");
var text = myP.innerHTML;
alert(text);
}*/

/*jQuery(document).ready(function(e) {
var myP = jQuery("#myP");
var text = myP.html();
alert(text);
});*/

/*$(document).ready(function(e) {
var myP = $("#myP");
var text = myP.html();
alert(text);
});*/

/*$().ready(function(e) {
var myP = $("#myP");
var text = myP.html();
alert(text);
});*/

/*$(function() {
var myP = $("#myP");
var text = myP.html();
alert(text);
});*/

//jQuery对象和DOM对象的转换
window.onload = function(){
//获得DOM对象
var myP = document.getElementById("myP");
//DOM对象转换成jQuery对象
var $myP = $(myP);
//将jQuery对象转换成DOM对象
var myP2 = $myP.get(0);

var text3 = myP2.innerHTML;
alert(text3);
}
</script>
</head>

<body>
<p id="myP">我的标签</p>
</body>
