https://github.com/dangrossman/bootstrap-daterangepicker
* 特性:
* (1)基本功能->支持日期范围选取
* (2)右边日期必须大于左边,否则无法'确认'提交.
(2.1)左边日历选中某个日期后,右边日历会计算可以选择的日期. 不能选择的日期颜色呈灰色.
(2.2)'确定'时会再次判断左边日期是否小于右边. 若不满足会对右边日历对应文本框进行变色提示.
* (3)支持required验证.继承自easyui validatebox .
基于[jQuery EasyUI 1.4.2],暂时使用的easyloader加载,测试的.

需要修改一些文件.
将src目录下的easyloader.js拷贝到根目录下,作如下修改. 在modules上添加对daterangebox的支持.
var modules = {
//daterangebox:
daterangebox:{
js:'jquery.daterangebox.js',
css:'daterangebox.css',
dependencies:['calendar','combo','linkbutton']
},
在my目录(新增的测试目录)下增加测试文件easyloader_daterangebox.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>easyuiloader daterangebox</title>
<!-- 1.4.2 -->
<script type="text/javascript" src="../jquery.min.js"></script>
<script type="text/javascript" src="../easyloader.js"></script>
<script type="text/javascript">
//
$(function(){
$('body').css({
'margin':'10px 20px'
});
var input1 = $('<input>').appendTo($('body')).attr('id', 'dd').attr('type','text');
easyloader.locale = "zh_CN";
easyloader.base = "../";
using('daterangebox', function(){
$('#dd').daterangebox();
});
});
</script>
</head>
<body>
</body>
</html>
要让例子程序正确运行,还需要修改下plugin目录下的jquery.combo.js文件. 原因是目前项目用的是低版本1.4.2见博文
src下没有jquery.combo.js的源文件,不过没关系,我已经测试过,直接修改148行.
//_21.panel("panel").show().css({zIndex:($.fn.menu?$.fn.menu.defaults.zIndex++:$.fn.window.defaults.zIndex++),left:-999999});
_21.panel("panel").show().css({zIndex:($.fn.menu?$.fn.menu.defaults.zIndex++:($.fn.window?$.fn.window.defaults.zIndex++:99)),left:-999999});
