                               class="item-li-content w37 fl bj-times"
                               onclick="WdatePicker({onpicked:function(){getListFormDate()},oncleared:function(){getListClearDate()},maxDate:getFromMaxDate(),minDate:getFromMinDate()})"
                               type="text">
                        <input id="to" readonly="readonly" autocomplete="off" placeholder="结束日期"
                               class="inp-ml30 item-li-content w37 fl bj-times"
                               onclick="WdatePicker({onpicked:function(){getListFormDate()},oncleared:function(){getListClearDate()},minDate:getToMinDate(),maxDate:getToMaxDate(),position:{left:-35,top:0}});"
                               type="text">
                    </p>


  //getListFormDate()  和getListClearDate()  是在input框里面输入内容或者没有内容的时候  选择完成以后触发的事情
