javascript - platform.js 和 IE11 中对象不支持属性或方法 'getAttribute' 错误

Question

从 IE 11 和 Polymer/平台收到以下错误

SCRIPT438: Object doesn't support property or method 'getAttribute'
File: platform.js, Line: 12, Column: 30816

我已声明以下元。

<meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />

该网站在 Chrome 中运行良好。所以我想这一定是一个可比性问题。有什么想法吗？

如果您使用的是 XHTML，那么自关闭标签可能是一个问题:

Serving the page as XHTML will permit self-closing tags, BUT breaks some scripts.

For example, I created this element:

<link rel="import" href="../bower_components/polymer/polymer.html"/>
<polymer-element name="copyright-statement" attributes="copyrightStart">
  <template>
    <span>
      &#169; {{copyrightStart}}{{thisYear}}
    </span>
  </template>
  <script>
    Polymer('copyright-statement',{
        copyrightStart:2014,
        created: function() {
            console.log("The copyright-statement has been registered.");
        },
        ready: function() {
            this.thisYear = new Date().getFullYear();
            if(this.copyrightStart != null) {
                if(parseInt(this.copyrightStart) < this.thisYear) {
                    this.copyrightStart = this.copyrightStart + " \u2014 ";
                } else {
                    this.copyrightStart = "";
                }
            }
        }
    });
  </script>
</polymer-element>
