我想在dom-if模板下重新运行聚合物元素的“就绪”事件

Question

if child element is visible under "dom-if" template, I want to rerun "ready" event of the child element.

are there any tips to rerun "ready" event of the child element?

The code is like below. in this case, I want to rerun "ready" event of owl-element

 <template is="dom-if" if="{{isPlugin(config.plugin,'owl')}}" id="owl"> <owl-element html$="{{config.html}}" autoplay-speed$="{{config.speed}}" tranisition$="{{config.transition}}" on-box-update="gotoNextBox"> </owl-element> </template>

Dom-if just hides element from the dom, but not destroy it. This is due to faster operation. You can add a 'restamp'-attribute to dom-if, which makes the dom-if elements recreate everytime it displays.

Example:

 <template is="dom-if" if="{{isPlugin(config.plugin,'owl')}}" id="owl" restamp>
