html+css3+jquery实现收缩展开左侧流程图列表
1、准备好需要用到的图标。
2、新建html文档。
3、书写hmtl代码。
<div id="sss">aaaa</div>
<div id="img_bag" class="ztb_nav"> <a href="javascript:void(0)" onmousedown="moveTop()" style="display:block; width:30px; margin:0 auto"> <img src="images/ztb_up.png" border="0" /></a>
<div id="img" class="ztb_content">
<div style="position:relative;">
<div class="online"></div>
<div class="ztb_main_01">
<ul class="ztb_content_01">
<li class="ztb_over"><a href="#" class="ztb_con_text" onclick="clickli(this);">场景用例 <span class="ztb_time">2017-05-25</span></a>
<ul class="ztb_content_02">
<li class="ztb_end"><a href="#">1.下拉类表测试</a></li>
<li class="ztb_end"><a href="#">2.单选框列表测试</a></li>
</ul>
</li>

<ul class="ztb_content_02">
<li><a href="#">1.下拉类表测试</a></li>

</ul>
</li>
<li> <a href="#" class="ztb_con_text" onclick="clickli(this);">组件测试</a>
<ul class="ztb_content_02">

</div>
</div>
<a href="javascript:void(0)" onmousedown="moveBottom()" style="position:absolute; bottom:0px; right:110px"> <img src="images/ztb_down.png" border="0" /></a> </div>
4、书写css代码。
* { margin: 0; padding: 0; list-style: none; }
img { border: 0; }
input { outline: none; }
ul, ol, li { list-style: none; }
table { border-collapse: collapse; border-spacing: 0; }
label, label input, button { vertical-align: middle; }
blr:expression(this.onFocus=this.blur());
outline:none;
area { blr:expression(this.onFocus=this.blur());
}
a:focus { -moz-outline-style: none; }
a.hidefocus { outline: none; }
.clear { clear: both; font-size: 0; height: 0; line-height: 0; }
body { font-size: 12px; font-family: "微软雅黑"; }
h1, h2, h3, h4, h5, h6 { font-weight: normal; font-size: 100%; }
a { color: #444444; text-decoration: none; }
.clearfix:after { visibility: hidden; display: block; font-size: 0; content: " "; clear: both; height: 0; }
.ztb_nav { background: #f1eded; position: absolute; left: 0px; right: 0px; top: 0px; bottom: 0px; width: 235px; _height: expression(document.documentElement.clientHeight-0+"px");
overflow: hidden; }
.ztb_up { height: 19px; width: 100%; margin-top: 10px; }
.ztb_down { height: 19px; width: 100%; position: absolute; bottom: 10px; }
.ztb_up a { display: block; cursor: pointer; width: 32px; height: 19px; margin: 0 auto }
.ztb_down a { display: block; cursor: pointer; width: 32px; height: 19px; margin: 0 auto }
.ztb_content { position: absolute; left: 0px; right: 0px; top: 29px; bottom: 29px; width: 235px; _height: expression(document.documentElement.clientHeight-58+"px");
overflow: hidden; }
.online { width: 1px; position: absolute; left: 20px; right: 0px; top: 0px; bottom: 0px; _height: expression(document.documentElement.clientHeight-0+"px");
overflow: hidden; border-left: 1px solid #ccc; z-index: 100 }
.ztb_main_01 { position: relative; z-index: 1000 }
.ztb_content_01 { padding: 20px 0px 20px 10px; z-index: 1000 }
.ztb_content_01 .ztb_con_text { font-size: 14px; color: #404040; background: url(../images/ztb_lc.png) no-repeat; padding-left: 40px; display: block; height: 24px; margin-bottom: 20px }
.ztb_content_01 .ztb_content_02 li { margin-bottom: 10px; background: url(../images/ztb_gx2.png) left center no-repeat; padding-left: 35px; margin-left: 5px }
.ztb_content_01 li { margin-bottom: 40px }
.ztb_over .ztb_con_text { font-size: 14px; color: #404040; background: url(../images/ztb_gx.png) no-repeat; padding-left: 40px; display: block; height: 24px; margin-bottom: 20px }
.ztb_content_01 .ztb_content_02 li.ztb_end { background: url(../images/ztb_gx1.png) left center no-repeat; }
.ztb_on .ztb_con_text { font-size: 14px; color: #404040; background: url(../images/ztb_active-6.png) no-repeat; padding-left: 40px; display: block; height: 24px; margin-bottom: 20px }
.ztb_content_01 .ztb_content_02 li.ztb_active { background: url(../images/ztb_active.png) left center no-repeat; }
.ztb_content_01 .ztb_content_02 li.ztb_active a { color: #2285d3; font-weight: bold }
.ztb_content_01 .ztb_content_02 li a:hover { text-decoration: underline }
.ztb_content_01 li a { display: block }
.ztb_content_01 .ztb_content_02 li.ztb_active a { }
.ztb_content_01 .ztb_content_02 li.ztb_online a { background: url(../images/ztb_sel.png) right center no-repeat; }
.ztb_content_01 .ztb_content_02 li.ztb_online a:hover { text-decoration: underline }
.ztb_con_text { font-weight: bold; }
.ztb_time { display: block; font-size: 12px; font-weight: normal }
5、书写并添加js代码。
<script src="js/jquery-1.9.1.min.js" ></script>
<script >
$(function(){
$('ul.ztb_content_02 li').click(function(){
$(this).addClass('ztb_online').siblings('li.ztb_online').removeClass('ztb_online');
$(this).parents('li').siblings('li').children('ul').find('li.ztb_online').removeClass('ztb_online');
})
})
</script>
<script>
function clickli(dom){
var ul = $(dom).next('ul');
if (ul.is(":hidden")) {
ul.css('display','block')
}else{
ul.css('display','none')
}
}
</script>
<script >
function js(obj){return document.getElementById(obj)}
var maxHeight=js("img").getElementsByTagName("ul")[0].getElementsByTagName("li").length*105;
//滚动图片的最大高度
var targety = 211;
//一次滚动距离
var dx;
var a=null;
function moveTop(){
var le=parseInt(js("img").scrollTop);
if(le>211){
targety=parseInt(js("img").scrollTop)-211;
}else{
targety=parseInt(js("img").scrollTop)-le-1;
}
scTop();
}
function scTop(){
dx=parseInt(js("img").scrollTop)-targety;
js("img").scrollTop-=dx*.3;
clearScroll=setTimeout(scTop,50);
if(dx*.3<1){
clearTimeout(clearScroll);
}
}
function moveBottom(){
var le=parseInt(js("img").scrollTop)+211;
var maxL=maxHeight-600;
if(le<maxL){
targety=parseInt(js("img").scrollTop)+211;
}else{
targety=maxL
}
scBottom();
}
function scBottom(){
dx=targety-parseInt(js("img").scrollTop);
js("img").scrollTop+=dx*.3;
a=setTimeout(scBottom,50);
if(dx*.3<1){
clearTimeout(a)
}
}
</script>
6、代码整体结构。
7、查看效果。
