Issue with RxDom: malfunctioning after creation of new ID

Currently, I am utilizing Reactive Extension DOM to listen for events from the DOM. Below is a snippet of my code:

var input = document.getElementById('test_id');
var source = Rx.DOM.change(input);
var subscription = source.subscribe(
        function (x) {
          console.log(x);
        },
        function (err) {
          console.log('Error: ' + err);
        },
        function () {
          console.log('Completed');
        });

The issue arises when test_id element is not present on the page upon completion of the document.ready event. In my case, the appearance of test_id is dependent on an AJAX request. How can I configure RxDom to handle this delayed notification?

Your assistance is greatly appreciated.

Answer №1

In order to update the Observable, it must be recreated.

When you use

document.getElementById('test_id');
and the specified element with id test_id is not found, null is returned. This means that the Observable cannot be refreshed because it does not have a target DOM element to refresh.

Therefore, the best approach is to generate a new Observable after adding HTML content from your Ajax request.
