jQuery UI Tooltip with dynamic content

StackOverflow https://stackoverflow.com/questions/23486648

Question

I use jQuery UI Tooltip Widget and there is code:

  $(function() {$( document ).tooltip({  
    content: 'connecting',
    content:function(callback) {
            $.get('teacher.php?teacherid=' + link,{}, function(data) {
            callback(data);
        });
    },

  })});

On my page i have:

<div title="" onmouseover="{link=1}">Alex Brown</div>
<div title="" onmouseover="{link=2}">John Black</div>

But it doesn't work. How can i send variable to JS that Alex Brown is teacher with ID=1, and John Black is teacher with ID=2?

UPD: Well, it was fixed

  <script>
  $(function() {$( document ).tooltip({ 
    show: 0,
    hide: 0,
    items: 'teacher',
    content: 'connecting',
    content: function(callback) {
            var x=$(this).attr('id') 
            $.get('teacher.php?teacherid='+x,{}, function(data) {
            callback(data);
        });
    },

  })});
  </script>

And in HTML i now have:

<teacher id="1">Alex Brown</teacher>
<teacher id="2">John Black</teacher>
<teacher id="3">Homer Simpson</teacher>
Was it helpful?

Solution

First you tag your links with a class

<div class="teacher-link" data-teacher="1" title="1" onmouseover="{link=1}">Alex Brown</div>
<div class="teacher-link" data-teacher="2" title="2" onmouseover="{link=2}">John Black</div>

Then hook your tooltips on that class

$(function() {$( ".teacher-link" ).tooltip({  
    content: 'connecting',
    content:function(callback) {
            var link = $(this).attr("data-teacher"); // here retrieve the id of the teacher 
            $.get('teacher.php?teacherid=' + link,{}, function(data) {
            callback(data);
        });
    },

  })});

On non html5 page you can use another attribute like title:

   var link = $(this).attr("title"); // here retrieve the id of the teacher

OTHER TIPS

I think it's best to use HTML5 custom attribute

<div class="teacher" data-id="1" title="">Alex Brown</div>
<div class="teacher" data-id="2" title="">John Black</div>

and script 

$(function() {
    $( ".teacher" ).tooltip({
       content: function() { return $(this).attr('data-id'); },
    });
});

You can play with this at: http://jsfiddle.net/pT3ed/4/

Just replace "return $(this).attr('data-id');" with your loader using $(this).attr('data-id') as id.

You should got for this:

$('body').tooltip({
    selector: '[data-toggle=tooltip]'
});
