为什么在IE中不起作用?
https://www.polymer-project.org/docs/polymer/polymer.html#computed-properties
<link rel="import" href="http://www.polymer-project.org/components/polymer/polymer.html">
<polymer-element name="square-element" attributes="square">
<template>
<input type="number" value="{{num}}"><br>
<em>{{num}}^2 = {{square}}</em>
</template>
<script>
Polymer('square-element', {
num: 2,
computed: {
square: 'num * num'
}
});
</script>
我在IE10,IE11中测试过.....但铬很好
感谢您的帮助..
Webcomponents规范尚未包含在所有浏览器中。某些浏览器需要填充符号才能提供聚合物功能。填充物在这里:
