Multiple hide show div_问答_开发者_运维开发者技术经验分享

I have been trying to do this all day. At the end i managed to get it working. I know it is not the best way to do.

Can someone please show me a better way. I need 12 altogether. It does not need to be check box either. It can be just a text. I got the idea from com/2006/12/14/using-jquery-to-show-hide-form-elements-based-on-a-checkbox-selection/

I managed to upload it on http://utilitybase.com/paste/wmq

If I got you right, you might play around with

<head>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js" type="text/javascript"></script>
  <script type="text/javascript">
    $(document).ready(function(){
      var prototype = $('.prototype').clone();

      $('.prototype > input[type="checkbox"]').live('click', function() {
        if($(this).is(':checked')) {
          var clone = prototype.clone();
          clone.find('input[type="checkbox"]').attr('checked', false);
          $(this).parent('.prototype').append(clone);
        } else {
          $(this).parent('.prototype').find('.prototype:last').remove();
        }
      });
    });
  </script>
</head>

<body>
  <form>
    <div class="prototype">
      <input type="text" name="" maxlength="30" />
      <label for="checkbox"> Check to enter another email address:</label>
      <input id="checkme" type="checkbox" />
    </div>
  </form>
</body>
</html>

EDIT: This add's a new input/label/checkbox prototype inside the current one or removes it's children on the other hand. You could add ids to the fields as well.

thats nice .

Did you try .each or .live

http://api.jquery.com/each/

http://api.jquery.com/live/

Hmm. Looking at your code on UtilityBase. Maybe try using the .siblings() jquery function. Then for the click of the checkbox you can do a $(this).siblings('div').hide()/show();

This usually works for me

$("div[id^='extra']").click(function(){
  $div = $(this);
  divID = $div.attr("id").substring(5);

//Hide div w/id extra
       $div.css("display","none");

        // Add onclick handler to checkbox w/id checkme
       $("#checkme"+divID).click(function(){

        // If checked
        if ($("#checkme"+divID).is(":checked"))
        {
            //show the hidden div
            $div.show("fast");
        }
        else
        {      
            //otherwise, hide it 
            $div.hide("fast");
        }

});

This should keep you from having to write the same thing multiple timesdiv

You could try something like this:

// isolate the first div. You can surely find a better way,
// using classes, containers, etc., but this works for now. 
// Hide all the others.
$('div:has(input):not(:first)').hide();

// For each checkbox, open the next div
$('input:checkbox').click( function(){
  if( $(this).is(':checked') ) {
    $(this).next('div').show('fast');
  } else {
    $(this).next('div').hide('fast');
  }
});
