jQuery Tipsy won't work with jQuery.each() and live:true

问题

Note: This question was marked as solved once, but it figured out that upgrading to the latest jQuery was fixed only one issue. Please see the updated question below for the remaining issue.

Hi all,

I have just run into a weird issue with jQuery.Tipsy.

Here's a simplified demo fiddle: http://jsfiddle.net/6nWtx/7/

As you can see, the lastly added a.tipsy2 element does not get tipsyfied. The .tipsy2 elements are being tipsyfied within a jQuery.each() function and at this point I have the problem. Without the each() it works. Unfortunately, I need .each() to iterate through the elements to do some other stuff before I call tipsy().

Any suggestion?

Here's the source code of Tipsy: https://github.com/jaz303/tipsy/blob/master/src/javascripts/jquery.tipsy.js

IMHO the problem is using the combination of jQuery.each() and Tipsy option live:true

Update:

The other stuff I want to do before calling .tipsy() is checking for some optional configuration.

For example: <a href="#" title="This is a tooltip" class="tipsyfy delayed">Help</a>"

In this example I will add the following option to Tipsy: delayIn:1000 If there is no delayed class associated to the element this parameter will be delayIn:0.

Using the same logic, I want to specify the following classes as well: show-top, show-left, show-right, show-bottom for the Tipsy option called gravity.

Example: <a href="#" title="This is a tooltip" class="tipsyfy delayed show-left">Help</a>"

The full code:

$(".tipsyfy").each(function () {
    var a = "s",
        b = 0;
    if ($(this).hasClass("show-left")) a = "w";
    else if ($(this).hasClass("show-down")) a = "n";
    else if ($(this).hasClass("show-right")) a = "e";
    if ($(this).hasClass("delayed") && $(this).attr("data-delayIn") != null) b = $(this).attr("data-delayIn");
    $(this).tipsy({
        gravity: a,
        fade: true,
        live: true,
        delayIn: b
    })
})

And here is a full jsFiddle demo with all the stuffs I want to do: http://jsfiddle.net/xmLBG/1/

If you use jQuery 1.7.1 instead of 1.6.4 it will work. Maybe that live feature is relying on something buggy with the older versions, or some not-yet-implemented feature.

Update: from what I understood, you want the tipsy plugin to be called to every element with the .tipsyfy class, present now or added in the future. You don't want to (or can't) call it explicitly before insertion. You're trying to accomplish that using the live option of the plugin. Is that right?

If that's the case I can offer a workaround. I tried to use on (since jQuery's live is deprecated) to bind some code to the load event, but it didn't work, so I bound it to mouseenter and checked whether or not the plugin was already built for that element. If not, it builds it and re-triggers the event.

$(document).on("mouseenter", ".tipsyfy", function(e) {
    if ( !$(this).data("tipsy") ) {
        e.preventDefault();
        var a = "s",
            b = 0;
        if ($(this).hasClass("show-left")) a = "e";
        else if ($(this).hasClass("show-down")) a = "n";
        else if ($(this).hasClass("show-right")) a = "w";
        if ($(this).hasClass("delayed") && $(this).attr("data-delayIn") != null) b = $(this).attr("data-delayIn");
        $(this).tipsy({
            gravity: a,
            fade: true,
            live: true,
            delayIn: b
        }).trigger("mouseenter");
        return false;
    }
});

Live example at jsFiddle.

For a small optimization, if the sole purpose of the .tispsyfy class is to instruct the plugin creation, and you don't need it afterwards, you can remove it prior to re-triggering the mouseenter. This way the checking code won't be called over and over again:

$(this).tipsy({...}).removeClass("tipsyfy").trigger("mouseenter");

As far as I can see, you don't need to iterate the nodelist. It looks like tipsy does that for you (see this jsfiddle, where in the first list every element gets its own tooltip (1,2,3).

KooiInc is right,

<a class="tipsy1" href="#" title="Tipsy">TipsyLink</a>
<a class="tipsy1" href="#" title="Tipsy">TipsyLink</a>
<a class="tipsy1" href="#" title="Tipsy">TipsyLink</a>
<br />
<div id="container"></div>
<input id="add" type="button" value="ok">

And

$(".tipsy1").tipsy({live:true,fade:true});
$(".tipsy2").tipsy({live:true});
$("#add").click(function() {
    $("#container").append('<a class="tipsy2" href="#" title="Tipsy">TipsyLink</a>');
});

That will work fine

My guess is that Tipsy are uses some kind of direct mapping to the result, not using the live (in 1.6) or on in newer versions of jQuery.
So when your trying to apply the plugin to the links with the class tipsy2 it cant find any (cause your adding it to the DOM at a later stage in your code). The easiest fix to this is just to run the tipsy function at a later stage, perhaps on document.ready.

// this works
$(".tipsy1").tipsy({live:true,fade:true});

// add new tipsy element (ok)
$(document.body).append('<a class="tipsy1" href="#" title="TipsyAjax">AjaxTipsy1</a><br/>');

// add new tipsy element (not ok)
$(document.body).append('<a class="tipsy2" href="#" title="Tipsy">TipsyLink</a>');

$(document).ready(function () {
    $(".tipsy2").each(function(){
       // I'm doing some other logic here before I call .tipsy()
       $(this).tipsy({live:true,fade:true});
    })
});

回答5:

Can't you do this instead? It is what you are asking.

$(".tipsy1,.tipsy2").tipsy({live:true,fade:true});
$(".tipsy2").each(function() {
    //do your stuff
});
