How to catch error when call ajax request to server

Hi all, i using ajaxSource to get data from server,
var kind = require('enyo/kind'), Model = require('enyo/Model'), AjaxSource = require('enyo/AjaxSource'); new AjaxSource({name: 'ajax'}); var MycontactCollection = kind({ name: 'MyContactCollection', kind: Collection, options: {parse: true}, source: 'ajax', url: '' parse: function (data) { // incoming data contains {status:..., result:...} return data.result; // returned data contains {[{user_id:..., name:...}, {...}]} } });
I see errored function in enyo.Collection Document but i don't know use it in my collection.
public errored(action, opts, res, source)→ undefined
How to catch error when server error.
Thank you very much.


  • try sending in a error function in your options block, like:
    options: {parse:true, 
    success: enyo.bind(this, this.successHandler), 
    error: enyo.bind(this, this.errorHandler)}
    (error might need be errored)
  • Thanks @psarin, i solved by set error: true in options property and overide errored function and check errorCode in my view to catch error.

    options:{ parse:true, error: true }, errored:function(){ console.log('loi goi api'); this.set('errorCode',true); },

  • Hmm, sending in an error handler in options should work, and wouldn't require you to overload the builtin error function which updates the internal STATUS.

    Collection.js line 1187
    			// we need to check to see if there is an options handler for this error
    			if (opts && opts.error) opts.error(this, action, opts, res, source);
  • @psarin I see errored function in collection.js
    errored: function (action, opts, res, source) {..
    But i don't know using it in my custom collection, because i see at least 2 params action, opts past this function
