Jquery datepicker change event trigger and input's default change event

问题

I have datepicker

  <input type='text' class='inp'>  
<script>
   $('.inp').datepicker();

  $(".inp").on("change",function (){ 
   console.log('inp changed');
  });
</script>

When I first change '.inp' manually type there a value, then immediately I click on datepicker's opened calendar. I get two 'change' event listeners. First from manual change, then from datepicker change. How can I avoid this?

回答1:

Set your input readOnly, it will help you to change the value of field through icon only.

<input type='text' class='inp' readOnly />

then use onSelect to get selected date, as following:

$(function() {
    $(".inp").datepicker({
        onSelect: function(dateText, inst) {
            // alert(dateText);
        }
    });
});

回答2:

Try using the onSelect function like:

$(function() {
    $( ".datepicker" ).datepicker({
        onSelect: function() {
        //your code here
    }});

This will be fired when they select a date from the calendar not when they are typing.

回答3:

You can have onSelect trigger the change event on the text field. This way editing the date via the text box or via the date picker behave the same.

$('.inp').datepicker({
  onSelect: function() {
    return $(this).trigger('change');
  }
);

$(".inp").on("change",function (){ 
   console.log('inp changed');
}

If you are using the bootstrap datepicker you can do the following:

$('.datepicker').datepicker()
    .on('changeDate', function(e){
        # `e` here contains the extra attributes
});

Thanks! Everybody, but I could not make field readonly one, this is requirement. So I had to reasearch myself. So I posting my final solution. I did unbinding for 150 ms, then bind again. I made a jquery plugin for this

function myfunc(that){
        $(that).one('change', function(){
                var that = this;
                setTimeout(function(){myfunc(that);}, 150);
                //some logic
            }
        )
}

myfunc(".inp");

Thank you everyone, this is what I used though,

function myfunction(x,x2){
    var date1 = new Date(x);
    var MyDateString; 
    MyDateString = date1.getFullYear()+ '/' + ('0' + (date1.getMonth()+1)).slice(-2) + '/' + ('0' + date1.getDate()).slice(-2);
    x2.value=  MyDateString;    
 }

x, being the datepicker value and x2 being the datepicker object

  $(function() {
        $("#birth_date").datepicker({
        onSelect: function() {
            console.log("You Code Here");
        }});
    });
