HashLocationStrategy

A LocationStrategyused to configure the Locationservice to represent its state in the hash fragment of the browser's URL.

class HashLocationStrategy extends LocationStrategy { onPopState(fn: LocationChangeListener): void getBaseHref(): string path(includeHash: boolean = false): string prepareExternalUrl(internal: string): string pushState(state: any, title: string, path: string, queryParams: string) replaceState(state: any, title: string, path: string, queryParams: string) forward(): void back(): void // 继承自 common/LocationStrategy abstract path(includeHash?: boolean): string abstract prepareExternalUrl(internal: string): string abstract pushState(state: any, title: string, url: string, queryParams: string): void abstract replaceState(state: any, title: string, url: string, queryParams: string): void abstract forward(): void abstract back(): void abstract onPopState(fn: LocationChangeListener): void abstract getBaseHref(): string }

说明

For instance, if you call location.go('/foo'), the browser's URL will become example.com#/foo.
