Jquery – Zeroclipboard multiple elements

clickjquerypopupwindowzeroclipboard

I'm having trouble creating multiple Zeroclipboard instantiations in my code, with each instantiation launching a popup window after it is invoked.

<a class="xxx" href="popup.url.php" ><span >FRSDE3RD</a>
<a class="xxx" href="popup.url2.php" ><span >FRSDE3RD2</a>
<a class="xxx" href="popup.url3.php" ><span >FRSDE3RD3</a>
$(document).ready(function(){
    ZeroClipboard.setMoviePath( 'path/to/swf/ZeroClipboard.swf' );
    // setup single ZeroClipboard object for all our elements
    clip = new ZeroClipboard.Client();
    clip.setHandCursor( true );

    // assign a common mouseover function for all elements using jQuery
    $('a.xxx').mouseover( function() {
        // set the clip text to our innerHTML
        var url = $(this).attr("href");
        var code = $(this).children('span').html();
        clip.setText( $(this).children('span').html() );//this.innerHTML );

        clip.glue(this);
        clip.addEventListener('onMouseDown', function(){
            clip.reposition(this);
            clip.setText( code );
        });

        clip.addEventListener('onComplete', function(){ 
            clip.reposition(this);
            popUp(url);
        }); 


    });
});

function popUp(URL)
{
    day = new Date();
    id = day.getTime();
    eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=1,scrollbars=1,location=1,statusbar=1,menubar=1,resizable=1,width=1024,height=768,left = 328,top = 141');");
}

I succeed on generating the copy to clipboard functionality, but if I use either onMouseUp, onComplete events to trigger popup function, it either fire like 4-5 popups or doesn't fire at all.

P.S. I tried to adapt the solution from How to load an Ajax response into clipboard using jQuery and ZeroClipboard? instead of ajax call just copy to clipboard and on complete to lunch a popup … as I said didn't worked for me.

What else I figured it out while having flashblocker enabled is that every time I rollover a CODE tag a new flash is being created on the same spot so this might be an explanation why I'm having 3-4 popup when I click it. If I rollover more, more popups come. Is there a way to stop the flash from creating on same spot or destroy on rollout?

after more research I got to my solution to this problem:

$("a.xxx").each(function() {
  //Create a new clipboard client
  var clip = new ZeroClipboard.Client();
  clip.setHandCursor( true );

  //Glue the clipboard client to the last td in each row
  clip.glue(this);

  var url = $(this).attr("href");
  //Grab the text from the parent row of the icon
  var code = $(this).children('span').html();    
  clip.setText(code);

  //Add a complete event to let the user know the text was copied
  clip.addEventListener('complete', function(client, text) {
    //alert("Copied text to clipboard:\n" + text);
    popUp(url);
  });
});

this is the solution if anyone else will get stuck on this problem.

Javascript – Event binding on dynamically created elements

As of jQuery 1.7 you should use jQuery.fn.on with the selector parameter filled:

$(staticAncestors).on(eventName, dynamicChild, function() {});

Explanation:

This is called event delegation and works as followed. The event is attached to a static parent (staticAncestors) of the element that should be handled. This jQuery handler is triggered every time the event triggers on this element or one of the descendant elements. The handler then checks if the element that triggered the event matches your selector (dynamicChild). When there is a match then your custom handler function is executed.

Prior to this, the recommended approach was to use live():

$(selector).live( eventName, function(){} );

However, live() was deprecated in 1.7 in favour of on(), and completely removed in 1.9. The live() signature:

$(selector).live( eventName, function(){} );

... can be replaced with the following on() signature:

$(document).on( eventName, selector, function(){} );

For example, if your page was dynamically creating elements with the class name dosomething you would bind the event to a parent which already exists (this is the nub of the problem here, you need something that exists to bind to, don't bind to the dynamic content), this can be (and the easiest option) is document. Though bear in mind document may not be the most efficient option.

$(document).on('mouseover mouseout', '.dosomething', function(){
    // what you want to happen when mouseover and mouseout 
    // occurs on elements that match '.dosomething'
});

Any parent that exists at the time the event is bound is fine. For example

$('.buttons').on('click', 'button', function(){
    // do something here
});

would apply to

<div class="buttons">
    <!-- <button>s that are generated dynamically and added here -->
</div>

Jquery – How to select an element with multiple classes in jQuery

If you want to match only elements with both classes (an intersection, like a logical AND), just write the selectors together without spaces in between:

$('.a.b')

The order is not relevant, so you can also swap the classes:

$('.b.a')

So to match a div element that has an ID of a with classes b and c, you would write:

$('div#a.b.c')

(In practice, you most likely don't need to get that specific, and an ID or class selector by itself is usually enough: $('#a').)
