Insert image into the title HTML attribute

I use poshy jQuery bubble and I need to insert an image inside the bubble.

With this plugin, the text inside the bubble was generated with the title attribute (I have di开发者_StackOverflowfferent text, its not the same image for each link, it's why I need that).

<a class="demo-tip-yellow" title="<img src='/static/images/school/parents/btn_nav  /btn_change.png'> " href="<?=site_url('school/parents/children/'.$item['id'])?>">

Is it possible to insert a string inside the title attribute, if yes, how?

Please don't misuse the title attribute, it is a very important one also in terms of accessibility (and even SEO). It should only contain simple text.

You could use the data- attributes to store the image source and retrieve it through jQuery. This is the best way you could achieve this.

Using this HTML:

<a data-tooltipimage="/static/images/school/parents/btn_nav/btn_change.png" 
    title="Something descriptive" 
    href="#" 
    class="demo-tip-yellow">

you can easily retrieve the attribute through

$('demo-tip-yellow').attr('data-tooltipimage');

or from jQuery 1.4.3, you can simply use

$('demo-tip-yellow').data('tooltipimage');

because jQuery automatically fetches data- attributes into the data object.

I don't know this exact plugin, but if you check the documentation, you certainly have a way to control where does the plugin get its data from and how it is displayed.

I checked Poshy Tip documentation: http://vadikom.com/demos/poshytip/

There is a way to set the content by a function, so the following may very well work:

<a href="http://linkurl" id="link" data-tooltipimage="http://imageurl" title="sometitle">link...</a>
<script type="text/javascript">
$('#link').each(function() {
    var img_url = $(this).data("tooltipimage");
    var tooltip = img_url ? "<img src='"+img_url+"' alt='' />" : $(this).attr("title");
    $(this).attr("title","");
    $(this).poshytip({
        content: function(updateCallback) {
            return tooltip;
        }
    });
});
</script>

You should set the data-tooltipimage only when you want image tooltip.

EDIT: an other approach, with a hidden element, where you can put anything:

<a href="http://linkurl" id="link" title="sometitle">
    link...
    <span class="hidden-tooltip-data" style="display: none;"><img />...</span>
</a>
<script type="text/javascript">
$('#link').each(function() {
    var tooltip = $(".hidden-tooltip-data",this).html();
    $(this).attr("title","");
    $(this).poshytip({
        content: function(updateCallback) {
            return tooltip;
        }
    });
});
</script>

EDIT 2: and another:

<a id="link1" href="http://linkurl" title="sometitle">link...</a>
<span id="link1_tooltip" style="display: none;"><img /><a></a>...</span>
<script type="text/javascript">
$('#link').each(function() {
    var linkid = $(this).attr("id");
    var tooltip = $("#"+linkid+"_tooltip").html();
    $(this).attr("title","");
    $(this).poshytip({
        content: function(updateCallback) {
            return tooltip;
        }
    });
});
</script>

I would go with this HTML:

<a class="tipped" href="/path/to/something.html">
    <img src="something-tooltip.png" alt="Real text of the tooltip."/>
    Something
</a>

Combined with this CSS:

a.tipped img {
    display: none;
}

a.tipped:hover img {
    position: absolute;
    display: block;
    margin: 10px 0 0 10px;
}

You won't need JS, but of course you can use it to animate the tooltip. In this case you can drop the a.tipped:hover img rule.

This way you won't commit an assault against the web,

while you should not be storing markup in the title tag, you could use:

<a class="demo-tip-yellow" title="<?php echo htmlentities(<img src='/static/images/school/parents/btn_nav  /btn_change.png'>);?> " href="<?=site_url('school/parents/children/'.$item['id'])?>">

Having the > inside an attribute might break the HTML as well. If you just want to have an image inside an overlay/bubble/lightbox i suggest looking at http://fancybox.net/

Which plugin are you using ?

Try to html encode <img src='/static/images/school/parents/btn_nav/btn_change.png'>. In PHP it's htmlentities() I think.
