IE11中点击el-menu报错Error in v-on handler: "TypeError: 对象不支持此操作
解决方案
新建一个js文件，在main.js中引入。注意此js引入需在elementui引入之前。
js文件内容入下
/* eslint-disable */
(function(window) {
try {
new MouseEvent('test');
return false; // No need to polyfill
} catch (e) {
// Need to polyfill - fall through
}
// Polyfills DOM4 MouseEvent
var MouseEvent = function(eventType, params) {
params = params || { bubbles: false, cancelable: false };
var mouseEvent = document.createEvent('MouseEvent');
mouseEvent.initMouseEvent(eventType, params.bubbles, params.cancelable, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
return mouseEvent;
};
MouseEvent.prototype = Event.prototype;
window.MouseEvent = MouseEvent;
}(window));
