I have a scoping problem that i cannot find a solution for in Google here is a simplified version of my code
jQuery.widget( "myNamespace.myPlugin", {
options: {},
_create: function() {
$main = this.element;
},
_init: function() {
$main.text('ajax running');
$.ajax({url:'some/url/path'})
.done(function(data) {
this._callback(data);
});
},
_callback: function() {
$main.text('ajax complete');
}
});
$('.widget_element').myPlugin();<html>
<head>
<script
src="https://code.jquery.com/jquery-2.2.4.min.js"
integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44="

crossorigin="anonymous"></script>
</head>
<div class="widget_element"></div>
</html>The error i am getting is:
TypeError: this._callback is not a function
Is there a better way of performing this task in within the widget environment?
Thanks
As with most problems, a solution only rears its head AFTER you post a question on SO
Aparently self = this is perfectly valid
jQuery.widget( "myNamespace.myPlugin", {
options: {},
_create: function() {
self = this;
$main = this.element;
},
_init: function() {
$main.text('ajax running');
$.ajax({url:'some/url/path'})
.done(function(data) {
self._callback(data);
});
},
_callback: function() {
$main.text('ajax complete');
}
});I hope this helps someone in the future
