1、说明事件
css:
<style type="text/css">
************************************
</style>
<body>
<div id="diyi">
<div id= "diyiti" onclick="dianji()"/>按钮</div>
</div>
</body>
js:
<script type="text/javascript">
function dianji(){
alert("弹出窗口");
}
</script>
2、经过或移出时出现按钮等
<div id="btn" onmousemove="over()" onmouseout="out()"/>鼠标经过出现按钮</div>
<button id="btn1" style="display: none;">按钮</button>
js：
var bs=0;
var btn=document.getElementById("btn1");
function over(){
if(bs=="0"){
btn.style.display='block';
bs++;
}
}
function out(){
if(bs<2){
btn.style.display='none';
}
bs=0;
}
3、网页换肤
<div class="name"></div>
js:
var name1=document.getElementsByClassName("name");
for( var i=0;i<name1.length;i++){
name1[i].onmouseover=function () {
this.style.backgroundColor="red";
this.style.height="200px";
this.style.width="100px";
}
name1[i].onmouseout=function () {
this.style.backgroundColor="blue";
this.style.height="100px";
this.style.width="200px";
}
}
4、显示与隐藏
点击显示，再点击就隐藏起来
<button id="xianshi" onclick="danji1()">显示隐藏</button><br>
<button id="yincang" style="display: none;">显示隐藏</button>
js：
var bs=0;
var yincang=document.getElementById("yincang");
function danji1(){
if(bs=="0"){
yincang.style.display="block";
bs++;
}
else if(bs<2){
yincang.style.display="none";
bs=0;
}
}
5、
1、竖向下拉导航 鼠标单击打开 再打击关闭

<div id="center2" style="display: none;">
<div id="neirong4" >内容1</div>
<div id="neirong5" >内容2</div>
<div id="neirong6" >内容3</div>
</div>
<!--标题3-->

<div id="center3" style="display: none;">
<div id="neirong7" >内容1</div>
<div id="neirong8" >内容2</div>
<div id="neirong9" >内容3</div>

bs=1;
}
}
var bs1=0;
var center2=document.getElementById("center2");
function dianji(){
if(bs1=="1"){
center2.style.display="none";
bs1=0;
}else if(bs1=="0"){
center2.style.display="block";
bs1=1;
}
}
var bs2=0;
var center3=document.getElementById("center3");
function danji3(){
if(bs2=="1"){
center3.style.display="none";
bs2=0;
}else if(bs2=="0"){
center3.style.display="block";
bs2=1;
}
}
2、横向下拉导航 鼠标放上显示 鼠标移开 关闭
