javascript学习之时间组件

写了一个时间组件,哪里需要哪里调(菜鸟级别,大牛路过就Ok了):

先有一个HTML文件:

 1 <!doctype>
 2 <html>
 3 <head>
 4 <title></title>
 5 <style>
 6 
 7 </style>
 8 <script src="calendar.js"></script>
 9 <script>
10 window.onload=function(){
11     myCalendar("date");
12 }
13 </script>
14 </head>
15 <body>
16 <form action="a.html">
17     <div style="position:relative; left:100px; top:10px;">
18         买票日期:<input type="text" name="date">
19     </div>
20     
21 </form>
22 </body>
23 </html>
View Code

接下来是一个Css样式文件:

 1 *{margin:0px;padding:0px;list-style:none;}
 2 .calendar{width:210px;border:1px solid #000; margin:0 auto;position:absolute;display:none;}
 3 .calendar h3{ height:30px; line-height:30px; text-align:center;}
 4 .calendar ol{ overflow:hidden; border-bottom:1px solid #ccc;}
 5 .calendar ol li{ width:30px; height:30px; line-height:30px; float:left; text-align:center;}
 6 .calendar ul {overflow:hidden;}
 7 .calendar ul li{ width:30px; height:30px; line-height:30px; float:left; text-align:center;font-family:"微软雅黑";font-size:14px;}

 8 .calendar .week{ color:red;}
 9 .calendar .pass{color:#ccc;}
10 .calendar .today{color:#fff;background:#f60;}
11 .calendar .prev,.calendar .next{position:absolute; top:10px; text-decoration:none;}
12 .calendar .prev{ left:10px;}
13 .calendar .next{ right:10px;}
14 /*.calendar #h3{font-family:"微软雅黑";font-weight:normal;font-size:16px;}*/

下边是Js文件:

  1 (function(){
  2     function getPos(obj){
  3         var t=0;
  4         var l=0;
  5         while(obj){
  6             t+=obj.offsetTop;
  7             l+=obj.offsetLeft;
  8             obj=obj.offsetParent;
  9         }
 10         return {top:t,left:l};
 11     }
 12     var added=false;//用来判断是否加载边Css文件
 13     
 14     window.myCalendar = function(name){
 15         var oInput = document.getElementsByName(name)[0];
 16         var oBox = document.createElement("div");
 17         oBox.className = ‘calendar‘;
 18         oBox.setAttribute(‘id‘,‘calendar‘);
 19         
 20         oInput.onclick = function(ev){

 27             oBox.style.left = getPos(oInput).left+‘px‘;
 28             oBox.style.top = getPos(oInput).top+oInput.offsetHeight+‘px‘;
 29             
 30         }
 31         
 32         // var onClicked = oBox.onclick = (function(){return true})();
 33         oBox.innerHTML=‘<a href="javascript:;" class="prev" id="prevMonty">←</a>‘
