<script>
document.getElementById("demo").innerHTML = "段落已修改。";

<script src="http://libs.baidu.com/jquery/1.10.2/jquery.min.js">
<script>
$(document).ready(function(){
$("button").click(function(){
$("p").hide();
});
});
</script>

<script>
//动画
$(document).ready(function(){
$("button").click(function(){
$("div").animate({

opacity:'0.5',
height:'150px',

1.判断ie浏览器：
//判断浏览器种类
var isIE = navigator.userAgent.indexOf("MSIE");
var isIE11 = navigator.userAgent.search(/Trident/i);
//ie浏览器时
if(isIE > 0 || isIE11 > 0){
  $("#page-container > div").css("margin-right","32%");
}

2.通过函数选中元素自身：
<li onclick="abc(this)">2222222</li>
function abc(obj){
$(obj).css("color","red");
}
