Question

In my case, i have some div and img tags. I am applying draggable & resizable operations to only div elements.

In one of the features, we have “Remove element” feature which removes the selected element dynamically. Everything works, after the delete function call, i am doing to Event binding again so that resizable and draggable can work again. Draggable works fine but resizable does not..

I tried many combinations like calling resizable(“destroy”).resizable(), but nothing works. The run time generated html from the dom looks little weird.

The problem arises when i delete the image and the dragClass div is present on the page. Then the dragClass div does not become functional to be resizable. Pls suggest some ideas to fix this problem.

Here is the jsFiddle Demo link.

Here is the example:-

  <div id="ParentDIV" style="margin-left:200px; width:800px; height:500px; background:lightgray;">                    
           <div class="dragClass"><p>Drag me around!</p></div>
           <br /><br />
           <img class="dragImgClass" src="logo3.JPG" />
           <br /><br />
           <img class="dragImgClass" src="logo4.JPG" />
       </div>
        <br /><br />
        <input id="Btn4" type="button" onclick="deleteObj();" value="Remove Element" />

The js:-

  $(function () {
            BindEvtHandlers();         

        });      //End of DOM Ready

        function BindEvtHandlers() {            
            $(".dragImgClass").draggable({ delay: 100, containment: "#ParentDIV", scroll: false })
                              .on("click", selectAction);

            $(".dragClass").draggable({ delay: 100, containment: "#ParentDIV", scroll: false })
                           .resizable()
                           .on("dblclick", editAction)
                           .on("click", selectAction)
                           .on("blur", "textarea", blurAction); 
           }


        function selectAction() {
            var $this = $(this); //get current obj.                     

            if ($this.get(0).tagName == "IMG")
                $('body').data('CBO', $this.attr('src'));
            else
                $('body').data('CBO', $this.find('p').html());

            $('body').data('selObj', $this);    
            $this.fadeTo('slow', 0.3);             
           }

        function deleteObj() {
            var $selObj = $('body').data('selObj');
            alert($selObj.outerHtml());           

            var cont = $('#ParentDIV').html();
            cont = cont.replace($selObj.outerHtml(), "");
            $('#ParentDIV').html(cont);


            $(".dragImgClass").draggable({ delay: 100, containment: "#ParentDIV", scroll: false })
                              .on("click", selectAction);

            $(".dragClass").resizable('destroy');
            $(".dragClass").draggable({ delay: 100, containment: "#ParentDIV", scroll: false })
                           .resizable()
                           .on("dblclick", editAction)
                           .on("click", selectAction)
                           .on("blur", "textarea", blurAction); 
        }

Answer 1

i found the easy solution to it. Inside the deleteObj fn, just stick one line after the first line and delete the rest of the code from the fn.

$selObj.remove(); 

This will remove element from the DOM tree rather than doing the string manipulation.
