Vue router/Element重复点击导航路由报错问题及解决

const originalPush = Router.prototype.push
Router.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
}
// 如果你的改了push还是没有生效，可以考虑改replace方法 
// 修改路由replace方法,阻止重复点击报错
const originalReplace = VueRouter.prototype.replace;
VueRouter.prototype.replace = function replace(location) {
  return originalReplace.call(this, location).catch(err => err);
};
