动态更改Vue标题

Question

如何根据页面动态更改页面标题？我有一个显示客户详细信息的页面，所以这个页面的标题应该是"；我的客户-ID1234"；。我已经成功地设置了标题"；我的客户"；在路由器中，但我不知道如何为每个页面动态定制。

在我的router.js:

const routes = [
{ path: '/', name: 'Home', component: Home, meta: { title: "Customer Data Center" } },
{ path: '/customer', name:'customer', component: Customers, meta: { title: "Customers" } },   // This is the part that I want to customize
];
// This callback runs before every route change, including on page load.
router.beforeEach((to, from, next) => {
const nearestWithTitle = to.matched.slice().reverse().find(r => r.meta && r.meta.title);
if(nearestWithTitle) document.title = nearestWithTitle.meta.title;
next();
});

我在这个版本上：

"vue": "^2.6.11",
"vue-router": "^3.2.0",

您可以更改Customers组件的created生命周期的页面标题。

created: function() {
document.title = `My Customer - ${customerID}`
}
