IE11-对象不支持属性或方法&包含'； [英] IE11 - Object doesn't support property or method 'contains'
本文介绍了IE11-对象不支持属性或方法&包含'；的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
使用Rappid我在IE11控制台中遇到错误：
Object doesn't support property or method 'contains'
此错误来自不具有该方法的SVGElement。Chrome中的相同代码可以运行。
我似乎需要为此缺少的方法填充PolyFill，但根据contains上的MDN文档，IE9和更高版本支持它，但SVGElement不支持它。
编辑：以下是一个代码片段-尝试在Chrome和IE11中运行

<div class="paper-container"></div>推荐答案
查找合适的填充this one
如果链接不起作用，代码如下：
SVGElement.prototype.contains = function contains(node) {
if (!(0 in arguments)) {
throw new TypeError('1 argument is required');
}
do {
if (this === node) {
return true;
}
} while (node = node && node.parentNode);
return false;
};
