Linking/unlinking jquery object to an element_问答_开发者

I'm using a jquery flowplayer tools plugin http://flowplayer.org/tools/tooltip.html

1)I want a tooltip to be created when user clicks on an element.

2)When the user clicks on another element, the old tooltip must be unlinked(deleted)

3)A new tooltip should be created(or old moved to) for the clicked element

4)So, there should <=1 tooltip on the page

Can you please help me?

Here's the code, it runs standalone

jQuery tools tooltip supports defining which events trigger the tooltip.

You do not need to handle the click event by yourself.

Edit: Updated the script. Click on the link to move the tooltip to the second element always.

Here is the script

var tt = $("h1").tooltip({
  events:{def:'click, click'},
  effect: "slide",
  tip: '.tooltip' ,
  position: "bottom center",
  api: true,
  delay: 30000
});

$("#ht").click(function() {
  tt.hide();
  $("#_2").tooltip().show();
});

The whole script

The FlowPlayer Tooltip has an API that is returned on EVERY call to tooltip.

You can then call hide on the API object.

Here's what your code should look like:

    var old_id, API;

//first time - create tooltip
    function my_create(id){
        API = $("#"+id).tooltip({ 
            effect: "slide", 
            tip: '.tooltip', 
            position: 'bottom center'
        });     
    }

 //next times - move tooltip to other element
    function my_unlink(id){
        API.unbind("mouseover"); 
        //todo
    }

    function my_link(id){
        my_create( id );
    }


    //THE MAIN FUNCTION

    function do_tip(new_id){
        if(old_id){
            my_unlink(old_id);
            my_link(new_id);
            alert(new_id);
        }
        else
            my_create(new_id);

        old_id=new_id;
     //new_id.focus();
 }

How about this alternative solution?
