一、问题:

【vue】Vue-Router报错:Uncaught (in promise)Error: Navigation cancelled from “/“ to “/1“ with a new navig_第1张图片
【vue】Vue-Router报错:Uncaught (in promise)Error: Navigation cancelled from “/“ to “/1“ with a new navig_第2张图片

二、分析:

该错误是因为vue-router的内部没有对编程式导航进行catch处理,所以在使用this.$router.push()this.$router.replace 进行路由跳转时,往同一地址跳转时或者在跳转的 mounted/activated 等函数中再次向其他地址跳转时会出现报错。但是在3.1.0版本及更高版本中,页面在跳转路由控制台会报Uncaught (in promise)的问题,push和replace方法会返回一个promise, 你可能在控制台看到未捕获的异常。声明式导航之所以不会出现这种问题,是因为vue-router在内部已经做了相关处理。

三、解决方案

//解决编程式路由往同一地址跳转时会报错的情况
const originalPush = Router.prototype.push;
const originalReplace = Router.prototype.replace;
//push
Router.prototype.push = function push(location, onResolve, onReject) {
  if (onResolve || onReject) {
    return originalPush.call(this, location, onResolve, onReject);
  }
  return originalPush.call(this, location).catch(err => err);
};
//replace
Router.prototype.replace = function push(location, onResolve, onReject) {
  if (onResolve || onReject) {
    return originalReplace.call(this, location, onResolve, onReject);
  }
  return originalReplace.call(this, location).catch(err => err);
};
