asp.net - Check date and time comparison in Javascript -


i have 4 textboxes date , each textbox there dropdownlist time.

now want is,

for each textbox date can same timing should not equal in dropdownlist.

for ex:-

if in each textbox date is

textbox1: 08/02/2016 textbox2: 08/02/2016 textbox3: 08/02/2016 textbox4: 08/02/2016

timing should not same, should be

ddl1 = 9.00 ddl2 = 10.00 ddl3 = 11.00 ddl4 = 12.00

what tried below:-

 function validaterecord() {     var strprierror = "";     if (document.getelementbyid('textbox1').value == document.getelementbyid('textbox2').value || document.getelementbyid('textbox3').value || document.getelementbyid('textbox4').value) {         if (document.getelementbyid('drptime').value == document.getelementbyid('drptime3').value || document.getelementbyid('drptime4').value || document.getelementbyid('drptime5').value) {             strprierror += "dates , time ra reminder cannot same";         }     }     if (strprierror != "") {         alert(strprierror);         return false;     }     else {         return true;     } }

but not working if add different time. kindly suggest

also, see screenshot of html

image1

update

the date format dd/mm/yyyy

the way checking time wrong. moreover, if have check, need check of them date object.

so need way, assuming these date textboxes:

  • textbox1
  • textbox2
  • textbox3
  • textbox4

and times are:

  • drptime
  • drptime3
  • drptime4
  • drptime5

now, need create 4 date objects, contain both date , time. say:

var dt1 = new date(document.getelementbyid('textbox1').value + " " + document.getelementbyid('drptime').value); var dt2 = new date(document.getelementbyid('textbox2').value + " " + document.getelementbyid('drptime3').value); var dt3 = new date(document.getelementbyid('textbox3').value + " " + document.getelementbyid('drptime4').value); var dt4 = new date(document.getelementbyid('textbox4').value + " " + document.getelementbyid('drptime5').value);

and need compare if there 2 way, , 6 comparisons:

dt1.gettime() == dt2.gettime() dt1.gettime() == dt3.gettime() dt1.gettime() == dt4.gettime() dt2.gettime() == dt3.gettime() dt2.gettime() == dt4.gettime() dt3.gettime() == dt4.gettime()

so, if condition invalid value be:

if (dt1.gettime() == dt2.gettime() || dt1.gettime() == dt3.gettime() || dt1.gettime() == dt4.gettime() || dt2.gettime() == dt3.gettime() || dt2.gettime() == dt4.gettime() || dt3.gettime() == dt4.gettime())     // error

the expanded 1 (for demo only) is:

if (     dt1.gettime() == dt2.gettime() || dt1.gettime() == dt3.gettime() || dt1.gettime() == dt4.gettime() ||     dt2.gettime() == dt3.gettime() || dt2.gettime() == dt4.gettime() ||     dt3.gettime() == dt4.gettime() )     // error

we comparing dates, if 1 condition true, i.e., 1 date equal one, need user error.

make sure date value in textbox of format:

yyyy/mm/dd

if not, not work.

working snippet

label {display: block;}
dates  <label>date 1: <input type="date" id="textbox1"></label>  <label>date 2: <input type="date" id="textbox2"></label>  <label>date 3: <input type="date" id="textbox3"></label>  <label>date 4: <input type="date" id="textbox4"></label>    times  <label>time 1: <input type="text" id="drptime"></label>  <label>time 2: <input type="text" id="drptime3"></label>  <label>time 3: <input type="text" id="drptime4"></label>  <label>time 4: <input type="text" id="drptime5"></label>    <button onclick="calc8();">calculate</button>    <script>    function calc8() {      var dt1 = new date(document.getelementbyid('textbox1').value + " " + document.getelementbyid('drptime').value);      var dt2 = new date(document.getelementbyid('textbox2').value + " " + document.getelementbyid('drptime3').value);      var dt3 = new date(document.getelementbyid('textbox3').value + " " + document.getelementbyid('drptime4').value);      var dt4 = new date(document.getelementbyid('textbox4').value + " " + document.getelementbyid('drptime5').value);      if (dt1.gettime() == dt2.gettime() || dt1.gettime() == dt3.gettime() || dt1.gettime() == dt4.gettime() || dt2.gettime() == dt3.gettime() || dt2.gettime() == dt4.gettime() || dt3.gettime() == dt4.gettime())      // error        alert("equal times detected");      else        alert("good go!");    }  </script>

instructions

  1. use same date (say 1st feb, use datepicker).
  2. use different time (say 1:00, 2:00, 3:00, 4:00).
  3. click button, should go.
