利用JS实现Web日历控件（包括日期和时间）
来源：互联网 发布：菲诗小铺的洗发水知乎 编辑：程序博客网 时间：2024/06/07 12:23
1.由于项目需要，需要一个精确到分钟的日历控件，具体如下图所示。
2.具体包括WebCalendar.js和一个schedule.jsp两个文件，源码如下。
（1）WebCalendar.js
var cal; var isFocus=false; //是否为焦点 var pickMode ={ "second":1, "minute":2, "hour":3, "day":4, "month":5, "year":6 }; var topY=0,leftX=0; //自定义定位偏移量 //选择日期，通过 ID 来选日期 function SelectDateById(id,strFormat,x,y) { var obj = document.getElementById(id);

<div class="tagContent" id="tagContent1"><p>开始调度时间： <form name="timing_form" method="post" action="" id="timing_form"> <table> <input type="text" placeholder="点击设置时间" name="startTime" value="" maxlength="100" id="Text3" onclick="SelectDate(this,'yyyy-MM-dd hh:mm')" readonly="true" style="width:120px;cursor:pointer" /> <input id="modelid" type="hidden" name="modelId" value="${userModel.modelid}"> <div class="input" style="margin-top:60px;"> <div class="button" onclick="timingSchedule();"><a href="javascript:void(0)">保 存</a></div> <div class="buttona"><a href="model/method=HandleModelList">取 消</a></div> </div> </form>3.上面js文件还可以提供各种不同精度的日历控件，具体如下。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head id="Head1"> <script src="WebCalendar.js" type="text/javascript"></script> </head> <body> <form name="form1" method="post" action="WebForm1.aspx" id="form1"> <input type="text" value="" maxlength="100" id="Txt_CreateDateST01" onclick="SelectDate(this,'yyyy 年')" readonly="true" style="width:265px;cursor:pointer" /> <input type="text" value="" maxlength="100" id="Txt_CreateDateST02" onclick="SelectDate(this,'yyyy 年 MM 月')" readonly="true" style="width:265px;cursor:pointer" /> <input type="text" value="" maxlength="100" id="Txt_CreateDateST03" onclick="SelectDate(this,'yyyy\/MM\/dd')" readonly="true" style="width:265px;cursor:pointer" /> <input type="text" value="" maxlength="100" id="Text1" onclick="SelectDate(this,'yyyy-MM-dd hh时')" readonly="true" style="width:265px;cursor:pointer" /> <input type="text" value="" maxlength="100" id="Text3" onclick="SelectDate(this,'yyyy-MM-dd hh:mm')" readonly="true" style="width:265px;cursor:pointer" /> </form> </body> </html>分别对应的效果如下图：
