datebox 和 datetimebox 添加『清空』按钮

需要引入 easyui-lang-zh_CN.js

$(document).ready(function(){

        var d_buttons = $.extend([], $.fn.datebox.defaults.buttons);
        d_buttons.splice(1, 0, {
            text: '清空',
            handler: function(target){
                $(target).datebox('setValue','');
            }
        });
        $('.easyui-datebox').datebox({
            buttons: d_buttons,
            editable:false,
            width:'100px'
        });

        var dt_buttons = $.extend([], $.fn.datetimebox.defaults.buttons);
        dt_buttons.splice(2, 0, {
            text: '清空',
            handler: function(target){
                $(target).datetimebox('setValue','');
            }
        });
        $('.easyui-datetimebox').datetimebox({
            buttons: dt_buttons,
            editable:false,
            width:'150px'
        });
    });
