Using jquery in Ember-cli

Question

I am relatively new to both Ember.js and Ember-cli and would really appreciate some help please with using a jquery tooltip in a custom view. All code is below, but when my template is injected, I get the following console error:

[Error] TypeError: 'undefined' is not a function (evaluating 'Ember.$().tooltip()')

I am using a custom view in a file called tooltip.js:

import Ember from 'ember';

export default Ember.View.extend({

  tagName:  'span',
  title:  'The tooltip title',
  html: true,
  placement:  'top',
  didInsertElement: function(){
    Ember.$().tooltip({"html": this.get('html'),  
                                        "title":this.get('title'),
                                        "placement":this.get('placement'), 
                                        container: 'body'});

  }
});

The relevant template code is:

{{#view "tooltip" titleBinding="item" placement="right"}}<span><img class="app_info_icon" id="typeInfoIcon" src="/assets/images/info_icon.png"></img></span>{{/view}}

How can I fix this please?

Answer 1

Solved as follows:

• Jquery's widgets etc. are not included in the standard jquery library which ember-cli uses. It has to be added using bower install --save jquery-ui
• You then have to add the following lines to Brocfile.js:

app.import('bower_components/jquery-ui/jquery-ui.js'); app.import('bower_components/jquery-ui/ui/tooltip.js');

• As @Leeft pointed out, when referencing jQuery from a view or component this.$() should be used, not Ember.$()
• Be sure to use a version of Ember-CLI after 0.40.

Answer 2

There are some issues in the code but just regarding error, Its coz you need to import the tooltip library(js file) into ember-cli. It is done in brocfile.js before calling app.toTree() like below

app.import('vendor/tooltip.js');
