IE11-对象不支持属性或方法&包含&#39；

前端问题
2022-01-01

IE11 - Object doesn#39;t support property or method #39;contains#39;(IE11-对象不支持属性或方法包含#39；)

本文介绍了IE11-对象不支持属性或方法&包含&#39；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;
};
