以下html文件未按预期显示结果。
我不知道这是什么问题。
<!DOCTYPE html>
<html>
<head>
<title>auto-binding test</title>
<script src="bower_components/webcomponentsjs/webcomponents.js"></script>
<link rel="import" href="bower_components/polymer/polymer.html"/>
</head>
<body unresolved>
<template id="greeter" is="dom-bind">
<template is="dom-repeat" items="{{names}}">
<p>Hello, {{item}}, how are you today?</p>
</template>
</template>
<script>
(function(){
document.querySelector('#greeter').names = ["Alice", "Brenda"];
})()
</script>
</body>
</html>

要绑定到子元素的textContent,您只需在子元素中包含注释即可。绑定注释当前必须跨越标记的整个内容:
<template>
First: <span>{{firstName}}</span><br>
Last: <span>{{lastName}}</span>
</template>
所以改为:
<p>Hello, <span>[[item]]</span>, how are you today?</p>
