I have a project with Polymer + Reveal.js
I have a view with polymer that gets all the Slides/Sections.
<template is="dom-repeat" items="[[my.slides]]" as="slide">
<section>
<h1>slide.title</h1>
<h2>slide.content</h2>
</section>
</template>
When I try to start Reveal.js, I have the issue related to:
(index):21136 Uncaught TypeError: Cannot read property 'querySelectorAll' of undefined
I think is because Reveal.js cannot select a Webcomponent generated by Polymer, because Reveal.js needs to have all slides content wrote on the html file by separate.
Then my question is: How to use Polymer Webcomponents with Reveal,js?
Alan: Yes, you are right.
Now I am creating DOM elements directly with JS avoiding Polymer shadowDOM elements.
Then I created a function called createSlides where - based in a JSON response - I appending slides (sections) within slides div.
Fist I create a Polymer template similar to:
<template>
<div class="reveal">
<div id="slides" class="slides">
<section>
This section will be removed
</section>
</div>
</div>
</template>
Next I removed the unused slide and appended some slides. Finally start the Reveal presentation
ready()
{
this.removeInitialSlide();
this.addSomeSlides();
this.startRevealPresentation();
}
clearInitialSlides()
{
var slidesComp = this.$.slides;
while (slidesComp.hasChildNodes()) {
slidesComp.removeChild(slidesComp.lastChild);
}
}
addSomeSlides()
{
var slide1 = document.createElement("section");
var image = document.createElement("img");
image.src = "some/path/to/image.jpg";
slide1.appendChild(image);
this.$.slides.appendChild(slide1);
var slide2 = document.createElement("section");
slide2.innerHTML = "<h1>Test content</h1>"
this.$.slides.appendChild(slide2);
}
Working fine for now.
