What is template-bound in polymer?

问题

I noticed there is a template-bound in firebase polymer firebase-login.html after searching polymer documentation cannot find out what is that.

also, any polymer events reference in documentation?

回答1:

This is the event that fires after the data binding happens in a Polymer's auto-binding template.

<template id="myTemplate" is="auto-binding">
</template>
<script>
    var template = document.getElementById("myTemplate");
    template.addEventListener('template-bound', function() {
        console.log('ready');
    });
</script>

The auto-binding template inserts the instances it creates immediately after itself in the DOM tree (not in its shadow DOM).

After adding the instances, the auto-binding template fires the template-bound event.
