Jquery UI tooltip does not support html content

Today, I upgraded all of my jQuery plugs-in with jQuery 1.9.1. And I started to use jQueryUI tooltip with jquery.ui.1.10.2. Everything was good. But when I used HTML tags in the content (in the title attribute of the element I was applying the tooltip to), I noticed that HTML is not supported.

This is screenshot of my tooltip:

How can I make HTML content work with jQueryUI tooltip in 1.10.2?

Edit: Since this turned out to be a popular answer, I'm adding the disclaimer that @crush mentioned in a comment below. If you use this work around, be aware that you're opening yourself up for an XSS vulnerability. Only use this solution if you know what you're doing and can be certain of the HTML content in the attribute.

The easiest way to do this is to supply a function to the content option that overrides the default behavior:

$(function () {
      $(document).tooltip({
          content: function () {
              return $(this).prop('title');
          }
      });
  });

Example: http://jsfiddle.net/Aa5nK/12/

Another option would be to override the tooltip widget with your own that changes the content option:

$.widget("ui.tooltip", $.ui.tooltip, {
    options: {
        content: function () {
            return $(this).prop('title');
        }
    }
});

Now, every time you call .tooltip, HTML content will be returned.

Example: http://jsfiddle.net/Aa5nK/14/

Instead of this:

$(document).tooltip({
    content: function () {
        return $(this).prop('title');
    }
});

use this for better performance

$(selector).tooltip({
    content: function () {
        return this.getAttribute("title");
    },
});

I solved it with a custom data tag, because a title attribute is required anyway.

$("[data-tooltip]").each(function(i, e) {
    var tag = $(e);
    if (tag.is("[title]") === false) {
        tag.attr("title", "");
    }
});

$(document).tooltip({
    items: "[data-tooltip]",
    content: function () {
        return $(this).attr("data-tooltip");
    }
});

Like this it is html conform and the tooltips are only shown for wanted tags.

You can also achieve this completely without jQueryUI by using CSS styles. See the snippet below:

div#Tooltip_Text_container {
  max-width: 25em;
  height: auto;
  display: inline;
  position: relative;
}

div#Tooltip_Text_container a {
  text-decoration: none;
  color: black;
  cursor: default;
  font-weight: normal;
}

div#Tooltip_Text_container a span.tooltips {
  visibility: hidden;
  opacity: 0;
  transition: visibility 0s linear 0.2s, opacity 0.2s linear;
  position: absolute;
  left: 10px;
  top: 18px;
  width: 30em;
  border: 1px solid #404040;
  padding: 0.2em 0.5em;
  cursor: default;
  line-height: 140%;
  font-size: 12px;
  font-family: 'Segoe UI';
  -moz-border-radius: 3px;
  -webkit-border-radius: 3px;
  border-radius: 3px;
  -moz-box-shadow: 7px 7px 5px -5px #666;
  -webkit-box-shadow: 7px 7px 5px -5px #666;
  box-shadow: 7px 7px 5px -5px #666;
  background: #E4E5F0  repeat-x;
}

div#Tooltip_Text_container:hover a span.tooltips {
  visibility: visible;
  opacity: 1;
  transition-delay: 0.2s;
}

div#Tooltip_Text_container img {
  left: -10px;
}

div#Tooltip_Text_container:hover a span.tooltips {
  visibility: visible;
  opacity: 1;
  transition-delay: 0.2s;
}

<div id="Tooltip_Text_container">
  <span><b>Tooltip headline</b></span>
  <a href="#">
    <span class="tooltips">
        <b>This is&nbsp;</b> a tooltip<br/>
        <b>This is&nbsp;</b> another tooltip<br/>
    </span>
  </a>
  <br/>Move the mousepointer to the tooltip headline above. 
</div>

The first span is for the displayed text, the second span for the hidden text, which is shown when you hover over it.

To expand on @Andrew Whitaker's answer above, you can convert your tooltip to html entities within the title tag so as to avoid putting raw html directly in your attributes:

$('div').tooltip({
    content: function () {
        return $(this).prop('title');
    }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<div class="tooltip" title="&lt;div&gt;check out these kool &lt;i&gt;italics&lt;/i&gt; and this &lt;span style=&quot;color:red&quot;&gt;red text&lt;/span&gt;&lt;/div&gt;">Hover Here</div>

More often than not, the tooltip is stored in a php variable anyway so you'd only need:

<div title="<?php echo htmlentities($tooltip); ?>">Hover Here</div>

From http://bugs.jqueryui.com/ticket/9019

Try to use javascript to set html tooltips, see below

$( ".selector" ).tooltip({
   content: "Here is your HTML"
});

To avoid placing HTML tags in the title attribute, another solution is to use markdown. For instance, you could use [br] to represent a line break, then perform a simple replace in the content function.

In title attribute:

"Sample Line 1[br][br]Sample Line 2"

In your content function:

content: function () {
    return $(this).attr('title').replace(/\[br\]/g,"<br />");
}

another solution will be to grab the text inside the title tag & then use .html() method of jQuery to construct the content of the tooltip.

$(function() {
  $(document).tooltip({
    position: {
      using: function(position, feedback) {
        $(this).css(position);
        var txt = $(this).text();
        $(this).html(txt);
        $("<div>")
          .addClass("arrow")
          .addClass(feedback.vertical)
          .addClass(feedback.horizontal)
          .appendTo(this);
      }
    }
  });
});

Example: http://jsfiddle.net/hamzeen/0qwxfgjo/

$(function () {
         $.widget("ui.tooltip", $.ui.tooltip, {
             options: {
                 content: function () {
                     return $(this).prop('title');
                 }
             }
         });
    
         $('[rel=tooltip]').tooltip({
             position: {
                 my: "center bottom-20",
                 at: "center top",
                 using: function (position, feedback) {
                     $(this).css(position);
                     $("<div>")
                         .addClass("arrow")
                         .addClass(feedback.vertical)
                         .addClass(feedback.horizontal)
                         .appendTo(this);
                 }
             }
         });
     });
    

thanks for post and solution above.

I have updated the code little bit. Hope this might help you.

http://jsfiddle.net/pragneshkaria/Qv6L2/49/

As long as we're using jQuery (> v1.8), we can parse the incoming string with $.parseHTML().

$('.tooltip').tooltip({
    content: function () {
    	var tooltipContent = $('<div />').html( $.parseHTML( $(this).attr('title') ) );
        return tooltipContent;
    },
});	

We'll parse the incoming string's attribute for unpleasant things, then convert it back to jQuery-readable HTML. The beauty of this is that by the time it hits the parser the strings are already concatenates, so it doesn't matter if someone is trying to split the script tag into separate strings. If you're stuck using jQuery's tooltips, this appears to be a solid solution.

You may modify the source code 'jquery-ui.js' , find this default function for retrieving target element's title attribute content.

var tooltip = $.widget( "ui.tooltip", {
version: "1.11.4",
options: {
	content: function() {
		// support: IE<9, Opera in jQuery <1.7
		// .text() can't accept undefined, so coerce to a string
		var title = $( this ).attr( "title" ) || "";
		// Escape title, since we're going from an attribute to raw HTML
		return $( "<a>" ).text( title ).html();
	},

change it to

var tooltip = $.widget( "ui.tooltip", {
version: "1.11.4",
options: {
	content: function() {
		// support: IE<9, Opera in jQuery <1.7
		// .text() can't accept undefined, so coerce to a string
		if($(this).attr('ignoreHtml')==='false'){
			return $(this).prop("title");
		}
		var title = $( this ).attr( "title" ) || "";
		// Escape title, since we're going from an attribute to raw HTML
		return $( "<a>" ).text( title ).html();
	},

thus whenever you want to display html tips , just add an attribute ignoreHtml='false' on your target html element; like this <td title="<b>display content</b><br/>other" ignoreHtml='false'>display content</td>

None of the solutions above worked for me. This one works for me:

$(document).ready(function()
{
	$('body').tooltip({
		selector: '[data-toggle="tooltip"]',
		html: true
	 });
});

Html Markup

Tool-tip Control with class ".why", and Tool-tip Content Area with class ".customTolltip"

$(function () {
                $('.why').attr('title', function () {
                    return $(this).next('.customTolltip').remove().html();
                });
                $(document).tooltip();
            });

Replacing the \n or the escaped <br/> does the trick while keeping the rest of the HTML escaped:

$(document).tooltip({
    content: function() {
        var title = $(this).attr("title") || "";
        return $("<a>").text(title).html().replace(/&lt;br *\/?&gt;/, "<br/>");
    },
});

add html = true to the tooltip options

$({selector}).tooltip({html: true});

Update
it's not relevant for jQuery ui tooltip property - it's true in bootstrap ui tooltip - my bad!
