cyclejs loses knowledge of DOM it rendered










0















I have a small cyclejs app and everything works except this one button click... other button clicks work



Cyclejs renders the element, but seems to lose track of its reference, and I cannot get the following:



// do not get this alert
sources.DOM.elements()
.filter(c => (document.getElementById('cameraButtonId') != null))
.take(1)
.map(c =>
alert('exists')
).addListener()

// cannot get this either after clicking
sources.DOM.select('#cameraButtonId').events('click').map(c2 =>
alert('click')
).addListener()


even though the following is rendered in the browser



<button class="cameraPermissionButton" id="cameraButtonId">Enable Camera Access</button>


I have no console.log errors or exceptions of any kind

          It doesn't lose the track of elements' status.



          You should use the selector provided by DOMSource (as you are doing already in the code below your comment // cannot get this either after clicking) instead of using a document selector within filter, i.e., .filter(c => (document.getElementById('cameraButtonId') != null)).



          For example,



          -sources.DOM.elements()
          - .filter(c => (document.getElementById('cameraButtonId') != null))
          +sources.DOM.select('#cameraButtonId').element()
          .take(1)
          .map(c =>
          alert('exists')
          ).addListener()
