JQuery :: Use Tagify Plug-in To Populate Text Field With Dynamic Labels?

Have the following code which (resides in a dialog box) and serves as an event listener for check boxes. Am able to populate / de-populate text field with values from check boxby checking or unchecking the individual check boxes:

// Event listener which picks individual contacts// and populates input field.
$('#emailCheckListId_ul input:checkbox').change(function() {
// Declare array
var emails = [];

[Code].....

However, when I use try to use theJQuery Tagifyplug-in it only creates one "tagified dynamic label" inside the text field but doesn't create another label when I click on an additional check box. Also, when I uncheck the original checkbox, itdoesn't remove the original label.

Here's my code using the JQuery tagify plug-in (all I did was keep everything the same as above but called the tagify functionon the text field):

// Add / Remove array from text fieldtextField.value = emails;
// Decorate with dynamic label
$(textField).tagify(emails);

I get this JavaScript error in the browser:

jquery.tagify.js: 'options' is undefined, line 71

In the source code this line reads:

_setOption: function( key, value ) { options.key = value;
},

Its stating that options.key is undefined...

Is there a way I can create an "else" for example:

// Iterate through each array and put email addresses into array$('#emailCheckListId_ul input:checkbox:checked').each(function(){
// do something
});
