新时代web组件开发标准

VUE框架，则是遵行了这个标准。

1、html文件

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title>My First WebComponent</title>
    <link rel="import" href="components/favorite-colour.html" />
</head>
<body>
    <favorite-colour></favorite-colour>
</body>
</html>

 

2、模板文件

<!-- WebComponent example based off element-boilerplate: https://github.com/webcomponents/element-boilerplate -->
<template>
    <style>
        .coloured {
            color: red;
        }
    </style>
    <p>My favorite colour is: <strong class="coloured">Red</strong></p>
</template>
<script>
    (function() {
        // Creates an object based in the HTML Element prototype
        var element = Object.create(HTMLElement.prototype);
        // Gets content from <template>
        var template = document.currentScript.ownerDocument.querySelector('template').content;
        // Fires when an instance of the element is created
        element.createdCallback = function() {
            // Creates the shadow root
            var shadowRoot = this.createShadowRoot();
            // Adds a template clone into shadow root
            var clone = document.importNode(template, true);
            shadowRoot.appendChild(clone);
        };
        document.registerElement('favorite-colour1', {
            prototype: element
        });
    }());
</script>
