Javascript日期时间验证

当我尝试验证以下日期时，只有一天得到验证。月份和年份没有得到验证。有人能推荐一下代码吗？提前谢谢！！我使用的日期格式是dd/mm/yyyy！！我正在使用IE7（这里没有其他选项）

函数日期检查（）{
风险值日期；
var logDate=document.getElementById（“f4”）.value；
var actionDate=document.getElementById（“f5”）.value；
var closureDate=document.getElementById（“f6”）.value；
var lDate=新日期（logDate）；
var cDate=新日期（closureDate）；
var aDate=新日期（actionDate）；
如果（cDate日期）日期=3；
如果（当前日期

不幸的是，你不能像那样比较日期。 您可以这样比较日期：

var date1 =new Date(logDate);
var date2 = new Date(closureDate);

if(date1.getTime() < date2.getTime()) {
    //date1 is smaller than date2
}

var date1=新日期（logDate）；
var date2=新日期（closureDate）；
if（date1.getTime（）

getTime

将日期返回为时间戳（从纪元开始的毫秒）

试试这个

function getDateFromFormat(val, format)

  val = val + "";
  format = format + "";
  format = format.replace('mm', 'MM');

  var i_format = 0;

  var token2 = "";
  var x, y;
  var now = new Date();
  var year = now.getYear();
  var month = now.getMonth() + 1;
  var date = 1;
  var hh = now.getHours();
  var mm = now.getMinutes();
  var ss = now.getSeconds();
  var ampm = "";
  while (i_format < format.length)
  {
    // Get next token from format string
    c = format.charAt(i_format);
    token = "";
    while ((format.charAt(i_format) == c) && (i_format < format.length))
    {
      token += format.charAt(i_format++);
    }
    // Extract contents of value based on format token
    if (token == "yyyy" || token == "yy" || token == "y")

谢谢！！下面的工作很好

我明白了。它很好用

              var d1=logDate.split(/[\-\ \:]/g);
    var d2=closureDate.split(/[\-\ \:]/g);
    var d3=actionDate.split(/[\-\ \:]/g);

    var lDate = new Date(d1[2], d1[1]-1, d1[0]);
    var cDate = new Date(d2[2], d2[1]-1, d2[0]);
    var aDate = new Date(d3[2], d3[1]-1, d3[0]);

其余代码与我的问题中的代码相同。

您可以尝试以下函数，该函数将日期解析为“dd/MM/yyyy HH:MM”格式

    function GetParsedDate(dt) {
        try {
            var dtValue = null;
            var arr1 = dt.split('/');
            var year = 0; var month = 0; var day = 0; var hour = 0; var minute = 0; var sec = 0;
            if (arr1.length == 3) {
                var arr2 = arr1[2].split(' ');
                if (arr2.length == 2) {
                    var arr3 = arr2[1].split(':');
                    try {
                        year = parseInt(arr2[0], 10);
                        month = parseInt(arr1[1], 10);
                        day = parseInt(arr1[0], 10);
                        hour = parseInt(arr3[0], 10);
                        minute = parseInt(arr3[1], 10);
                        //sec = parseInt(arr3[2], 10);
                        sec = 0;
                        dtValue = new Date(year, month - 1, day, hour, minute, sec);
                    }
                    catch (er) { alert('GetParsedDate (1): ' + er); }
                }
            }
            return dtValue;
        }
        catch (err) { alert('GetParsedDate: ' + err); }
    }

基本上它比较两个数字。这实际上应该行得通。你可以发布你的两个日期，我可以试试吗？这些日期是由用户在JSP页面上给出的。我使用了日期选择器来选择日期。

              var d1=logDate.split(/[\-\ \:]/g);
    var d2=closureDate.split(/[\-\ \:]/g);
    var d3=actionDate.split(/[\-\ \:]/g);

    var lDate = new Date(d1[2], d1[1]-1, d1[0]);
    var cDate = new Date(d2[2], d2[1]-1, d2[0]);
    var aDate = new Date(d3[2], d3[1]-1, d3[0]);

    function GetParsedDate(dt) {
        try {
            var dtValue = null;
            var arr1 = dt.split('/');
            var year = 0; var month = 0; var day = 0; var hour = 0; var minute = 0; var sec = 0;
            if (arr1.length == 3) {
                var arr2 = arr1[2].split(' ');
                if (arr2.length == 2) {
                    var arr3 = arr2[1].split(':');
                    try {
                        year = parseInt(arr2[0], 10);
                        month = parseInt(arr1[1], 10);
                        day = parseInt(arr1[0], 10);
                        hour = parseInt(arr3[0], 10);
                        minute = parseInt(arr3[1], 10);
                        //sec = parseInt(arr3[2], 10);
                        sec = 0;
                        dtValue = new Date(year, month - 1, day, hour, minute, sec);
                    }
                    catch (er) { alert('GetParsedDate (1): ' + er); }
                }
            }
            return dtValue;
        }
        catch (err) { alert('GetParsedDate: ' + err); }
    }
