解决办法，每次addroute时 深复制组件对象
import time from "../views/time"
function copyObj(obj) {
if (typeof obj == "object") {
if (Array.isArray(obj)) {
let arr = [];
for (let item of obj) {
arr.push(Object.assign(copyObj(item)));
}
return arr;
} else if (obj == null) {
return null;
} else {
let obj1 = {};
for (let index in obj) {
obj1[index] = copyObj((obj[index]));
}
return obj1;
}
} else if (typeof obj == "function") {
return Object.assign(obj);
} else if (typeof obj == undefined) {
return undefined;
} else {
return obj;
}
}
window.pushTime = function () {
let t = new Date().getTime();
let path = `/time/${t}`;
time = copyObj(time)
this.$router.addRoute({
path,
name: path,
component: time,
});
this.$router.push({
path,
});
}
