jQuery UI draggable is not working on newly create

2019-04-23 05:11发布

I have some DOM element which is draggable using jQuery UI.All are working fine but when i create some element using jQuery , then they are not draggable at all. i.e

$('div.draggable').draggable(); //Existing element , it works :)
$('p.draggable').draggable() ; //Newly created paragraph with same class name, it doesnt work at all :(

Thanks in advance !!!

I am trying This :

<script type="text/javascript">
     $(document).ready(function(){
         $('body').append('<p class="draggable">Newly Created Paragraph</p>');
         $('p.draggable').draggable(); **//This is not working**
     });
</script>

However Somehow this is working

    <script type="text/javascript">
     $(document).ready(function(){
         $('body').append('<p class="draggable">Newly Created Paragraph</p>')
                 .find('p.draggable').draggable(); **This is working**

     });
</script>

I know its been a while, but this problem recently bugged me too. As someone else mentioned, you got to rerun .draggable() on the newly created item, but that doesn't work if you defined certain options in your .draggable(). Also what didn't work was putting the $().draggable() in a function and then calling the function after creating a new element (this trick does however work with resetting droppables - go figure).

Anyway, long story short -> Putting the $().draggable() setup in a function and then calling the function after creating new element DID WORK, but i had to TAKE IT OUT of the document ready function..... after i disabled that, it worked.

You can call that function as many times and it keeps on working after every created element. It seems if it's in the document.ready statement then its a 1 shot deal..

Hope that helps.
