Question

I have a list of items. When the user clicks on an item, the user will be taken to item details page.

I want to pass an object containing item details(like item's image URL) to the route. However, I don't want to expose it in the routes url.

If there were a way to do something like <a route-href="route: details; settings.bind({url: item.url})">${item.name}</a> that would be gold.

I have seen properties can be passed to a route if defined in the route configuration. However, I don't know how to change that from the template. Another way could be is to define a singleton and store the values there and inject the object to the destination route.

Is there a way to pass values to routes from view (like angular ui-routers param object)?

Answer 1

好的，所以我找到了一种方法来实现更接近我想要的东西：

目标：将数据传递到路线，而不会在位置栏中公开它们。

假设我们有一个用户列表，我们希望将username传递给用户的个人资料页面，而不将其定义为查询参数。

在视图模型中，首先注入Router，然后将数据添加到目标路由器：

goToUser(username) {
    let userprofile = this.router.routes.find(x => x.name === 'userprofile');
    userprofile.name = username;
    this.router.navigateToRoute('userprofile');
}

现在，当路线更改为userprofile时，您可以将路线设置作为activate方法的第二个参数进行访问：

activate(params, routeData) {
    console.log(routeData.name); //user name
}

Answer 2

对于那些@Sayem的答案无效，您可以将任何其他数据（甚至对象）放入设置属性中，如下所示：

let editEmployeeRoute = this.router.routes.find(x => x.name === 'employees/edit');
editEmployeeRoute.settings.editObject = employeeToEdit;
this.router.navigateToRoute('employees/edit', {id: employeeToEdit.id});

因此editObject将在另一侧传递：

activate(params, routeConfig, navigationInstruction) {
    console.log(params, routeConfig, navigationInstruction);
    this.editId = params.id;
    this.editObject = routeConfig.settings.editObject;
}

希望这可以帮助其他人遇到与我相同的问题。 TG。
