如何用js写，判断一个时间格式？

懒得写，自己从里边找吧

  1.   

    <script>
    function  aa(){
    var a=document.form1.text1.value
    var i
    var j=document.form1.text1.value.lenght
    for (i=0,i>=j,i++){
       if(i%2==0){
         if(i%1==0){
            if(a.substr(3,4)=="-"){
               if(a.substr(6,7)=="-"){
                  if(a.substr(9,10)==" "){
                     if(a.substr(12,13)==":"){
                     document.alert("是日期型")
                                             }
                     else{
                     document.alert("否日期型")
                         }
                           }
                       }
                    }
                }
           }
    }
    </script>
    <body>
    <form action="" name="from1">
    <input type="text" name="text1">
    <input type="submit" name="submit1" onclick="aa()">
    </form>
    </body>
      

  2.   

    上面的符号打错拉
    <script>
    function  aa(){
    var a=document.form1.text1.value
    var i
    var j=document.form1.text1.value.lenght
    for (i=0,i=j,i++){                           〈〈-----------******************
       if(i%2==0){
         if(i%1==0){
            if(a.substr(3,4)=="-"){
               if(a.substr(6,7)=="-"){
                  if(a.substr(9,10)==" "){
                     if(a.substr(12,13)==":"){
                     document.alert("是日期型")
                                             }
                     else{
                     document.alert("否日期型")
                         }
                           }
                       }
                    }
                }
           }
    }
    </script>
    <body>
    <form action="" name="from1">
    <input type="text" name="text1">
    <input type="submit" name="submit1" onclick="aa()">
    </form>
    </body>
      

  3.   

    <script>
    alert((/^\d{4}\-\d{2}\-\d{2}\s\d{2}\:\d{2}$/).test('2004-10-08 25:99:59'));
    alert((/^\d{4}\-\d{2}\-\d{2}\s\d{2}\:\d{2}$/).test('2004-10-08'));
    alert((/^\d{4}\-\d{2}\-\d{2}\s\d{2}\:\d{2}$/).test('2004-10-08 25:99'));
    </script>这个就可以了
