如何在按钮onclick后禁用按钮

Question

I have a button using onclick return confirm ... I wish when the confirm submitted... the second time to click the button it will pop up alert message to inform the user button only can click once time.

SO far , I have already try the one function but not working.

$("#once").one("click", function() {
  alert('this only happens once');
});

The following code is my button

<input type="submit" id="once" class="button" style="width:100px;" onclick="return  
confirm('Are you sure you want <?php  echo $show_venue['venue'];?>  be your party venue 
 ?');"  value="CHOOSE" name="choose_venue">

Answer 1

You're not disabling the button after the click.

$(this).prop('disabled', true);

Here's a fiddle with the code you are after: http://jsfiddle.net/UT79m/6/

Answer 2

You could add a class to set a 'selected' state after the first click:

$("#once").on("click", function() {
   if($(this).hasClass('selected'))
       return;
   alert('this only happens once');
   $(this).addClass('selected');
});
