The resultant behaviour as far as I can tell is undefined, but will probably overwrite the function (effectively deleting the function from memory). To use ajaxResponse as a function you need to change the above to rename or remove the assigned variable and add an on-ajax-response="ajaxResponse" attribute. Don't forget to alter the textarea definition for the updated variable name below. > </iron-ajax> > <textarea value="{{ajaxResponse.degree}}"></textarea> > </template> > > <script> > Polymer({ > is: 'gauge-ajax' The next two characters are incorrect for Polymer 1.0, which only has one argument to the Polymer function, > }, so, remove the curly bracket but leave the comma (you can move the comma onto the end of the is: line if it looks more neat). > ajaxResponse: function(request) { > console.log(request.detail.response); > console.log(this.$.ajax.lastResponse); > } You now need to close the function request and object argument with "});" without the quotes. > </script>
