javascript - Validate date so that the date cannot be in future or in past -


i have form has date input. best way in javascript can ensure value selected neither future date or past date. have implemented jquery date picker select date see code below

<html>    <!--maina-->  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">  <script src="//code.jquery.com/jquery-1.10.2.js"></script>    <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>  <link href="main.css" rel="stylesheet" type="text/css"/>    <script>  $(function() {      var date = $('#datepicker').datepicker({ dateformat: 'yy-mm-dd' }).val();  });    function validateform(){  	var date_of_circulation = document.forms["myform"]["date_of_circulation"].value;  		if (date_of_circulation == null || date_of_circulation ==""){  			alert ("you have select date manuscript circulated");  			return false;  		}  	}  </script>    <form enctype="multipart/form-data" name = "myform" action = "" onsubmit="return validateform()" method = "post">  date of circulation:<input name="date_of_circulation" input type="text" id="datepicker"></p>  <input name = "add_manuscript" type="submit" value = "submit">  </form>  </html>

you can this

var yourdate = new date("12/5/2015"); //input value  var todaydate = new date(); //gets today's date value

you have use function sethours

if(yourdate.sethours(0,0,0,0) == todaydate.sethours(0,0,0,0)); {     //do stuff }

note: can using jquery's datepicker

var currentdate = new date(); $("#datepicker").datepicker("setdate", currentdate);

so can sure today's date selected.

edit: can @ datejs

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
