下面的例子则是利用get拦截,实现一个生成各种 DOM 节点的通用函数dom。
<body>
</body><script>const dom = new Proxy({}, {get(target, property) {return function(attrs = {}, ...children) {const el = document.createElement(property);for (let prop of Object.keys(attrs)) {el.setAttribute(prop, attrs[prop]);}for (let child of children) {if (typeof child === 'string') {child = document.createTextNode(child);}el.appendChild(child);}return el;}}
});const el = dom.div({},'Hi, my name is ',dom.a({href: 'https://blog.csdn.net/qq_22744093?type=blog'}, 'kexuexiong'),'. I like:',dom.ul({},dom.li({}, 'The web'),dom.li({}, 'Food'),dom.li({}, '…actually that\'s it'))
);document.body.appendChild(el);</script>
输出结果:
