我正在使用ng-route,我想要做的是在将客户发送到一页或显示警告消息之前进行验证。
每个例子,让我们假设我有两种类型的客户:
$scope.idCostumer = 15;
var costumerGood = 1;
var costumerBad = 2;
我的想法是验证类似这样的内容:
$scope.sendTo = function(){
if(costumerGood === 1){
location.path(hash).search({id: $scope.idCostumer});
}
else{
alert("You can't access here);
}
}
我知道正确的路径将是:
$scope.sendTo = function(hash){
location.path(hash).search({id: $scope.idCostumer});
}
但是验证没有用。控制台错误向我显示的是location.path is not a function
。有验证的方法吗?
我正在使用Javascript和AngularJs。
先感谢

我不确定您是否很好地理解了您的问题,但是如果您尝试管理对页面/组件的访问,我建议使用Route Guards机制:https://angular.io/guide/router#milestone-5-route-guards
您将能够在后卫中实施您的想法。 警卫队的例子:
import { Injectable } from '@angular/core';
import {
CanActivate, Router,
ActivatedRouteSnapshot,
RouterStateSnapshot,
CanActivateChild,
NavigationExtras
} from '@angular/router';
import { AuthService } from './auth.service';
@Injectable()
export class AuthGuard implements CanActivate, CanActivateChild {
constructor(private authService: AuthService, private router: Router) {}
canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
let url: string = state.url;
return this.checkPermissions(url);
}
canActivateChild(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
return this.canActivate(route, state);
}
checkPermissions(url: string): boolean {
if (this.authService.isLoggedIn) { return true; }
// Store the attempted URL for redirecting
this.authService.redirectUrl = url;
// Create a dummy session id
let sessionId = 123456789;
// Set our navigation extras object
// that contains our global query params and fragment
let navigationExtras: NavigationExtras = {
queryParams: { 'session_id': sessionId },
fragment: 'anchor'
};
// Navigate to the login page with extras
this.router.navigate(['/login'], navigationExtras);
return false;
}
}
如果您可以指出所使用的Angular版本,将会很有帮助。
