I want to create my own iron-ajax element, that does what iron-ajax does but a little more, add some headers to the request, at the moment I always add the header via data-binding to the headers property of iron-ajax but I dont want to code that on every element I build, I want the iron-ajax Element to do this by itself.
Is there a way to extend iron-ajax?
Edit:
<template>
<iron-ajax
auto
url="[[url]]"
handle-as="json"
debounce-duration="1000"
on-response=""
headers="[[headers]]"
></iron-ajax>
</template>
<script>
(function() {
'use strict';
Polymer({
is: 'em-ajax',
properties: {
headers: {
type: Object,
computed: 'computeHeaders(token)'
},
token: {
type: String,
notify: true,
value: "asdf"
},
url: {
type: String
}
},
computeHeaders: function() {
return {'Authorization' : 'Bearer {' + app.accessToken + '}'};
},
handleRequest: function(request) {
console.log("handling request", request);
request.header = this.computeHeaders();
}
});
})();
</script>
<em-ajax
url="http://api.asdf.safd.sdf/profile"
on-response="handleProfile"
></em-ajax>
How can I handle the on-response? Passing a String with the method name does not seem to work.
The Answer I marked is correct. For my edited question I found a solution:
this.fire('em-response', {event: event, request: request});
I fire an event in my custom ajax Element, and in the element I use the custom ajax element I added a listener. Is this a good solution?
You can embed <iron-ajax>
into your own <fancy-ajax>
component and forward properties in and out between <fancy-ajax>
and <iron-ajax>
.
<dom-module id="fancy-ajax">
<template>
<iron-ajax ...></iron-ajax>
</template>
</dom-module>
