从结束日期减去今天的日期，如果剩余日期小于6个月，则给出消息

Question

我正在laravel 中处理表单验证、护照签发日期和护照结束日期

 <div class="control-group">
    {!! Form::label('passportIssuedate', 'Passport Issue Date') !!}
    <div class="controls">
        {!! Form::date('passportIssuedate', null, 
     array('id'=>'issuedate',                   
    'class'=>'span8 form-control')) !!}
    </div>
    <!-- /controls -->
    </div>

     <div class="control-group">
    {!! Form::label('passportExpirydate', 'Passport Expiry Date') !!}
    <div class="controls">
        {!! Form::date('passportExpirydate', 
    null, array('id'=>'expdate', 'class'=>'span8 form-control')) !!}
    </div>
    </div>

我能做这个吗？

$(document).ready(function(){
var todaydate = $.now();
var enddate = getElementbyID('#expdate').value;
var result = enddate - todaydate;
 if(result < 6 months){
   alert("the expiry date duration should be more than six months");
  }
});

任何帮助，提前不胜感激。thnx很多。

Answer 1

假设"enddate"one_answers"todaydate"是"Date"对象的实例，则可以执行

diffInMs = enddate.getTime() - todaydate.getTime();
diffInDays = diffInMs /1000/ 60 / 60 / 24;

Answer 2

试试这个：

$(document).ready(function(){
var todaydate = new Date();
var enddate = new Date($('#expdate').text()); // input format is yyyy-mm-dd
var result = enddate - todaydate;
 if(result < 6 months){
   alert("the expiry date duration should be more than six months");
  }
});

在moment.js中，我已经完成了任务

<script src="{{ URL::asset('js/moment.js')  }}"></script>
<script type="text/javascript">
   $(document).ready(function(){
        $('#lastdate').blur(function(){
            mydate();
        });        
    });
   function mydate(){
        var duration = moment.duration(6, 'M').humanize();
        var lastdate = $("#lastdate").val();
        var today = moment().format('L');
        var ldate = moment(lastdate).diff(moment(today));
        var Result = moment.duration(ldate).humanize();
        //alert(Result);
        if(Result <= duration){
            var itsays= "some text message";
            $(".classnametobeshowninview").html(itsays);
        }else{
            $(".classnametobeshowninview").html("");
        }
   }
</script>
