AngularJS Question

Bootstrap tooltip with angularjs using $http to load the content of the tooltip

I am running into small issue that I can't seem to figure out. The code below works, except for the first time you hover over the link. Any help is greatly appreciated.

http://jsfiddle.net/LpK6d/1/

<div ng-app="myApp">
<a
class="pop-over"
data-original-title="default value"
data-placement="top">test link</a>
</div>


var app = angular.module("myApp", []);

app.directive('popOver', function($http) {
return {
restrict: 'C',
link: function(scope, element, attr) {

element.bind('mouseover', function(e) {
$http.get("http://ip.jsontest.com/?callback=someFunction")
.success(function(data) {
attr.$set('originalTitle', data);
element.tooltip();
});
})
}
}
});

Answer

Ok so calling .tooltip() before the AJAX call might seem like a good idea, but the method copies the data-original-title or 'title'into its internal variables so we can't change it :(.

the thing is that calling tooltip() it just listens to onmouseover events. You have to call .tooltip('show') to make it appear programmatically.

Here is the working fiddle : http://jsfiddle.net/rB5zT/49/

This is the correct way to do it:

var app =  angular.module("myApp", [])
app.directive('popOver', function($http) {
 return {
  restrict: 'C',
  link: function(scope, element, attr) {
    var i =0;
    element.tooltip();
    $(element).bind('mouseover',function(e) {

        $http.get("test").success(function(){
           attr.$set('originalTitle', "Some text "+i++);  
            element.tooltip('show');
         });
        });
   }
 }
});
