Class Description
Depending on which LocationStrategy
is used, Location
will either persist
to the URL's path or the URL's hash segment.
Note: it's better to use Router
service to trigger route changes. Use
Location
only if you need to interact with or create normalized URLs outside of
routing.
Location
is responsible for normalizing the URL against the application's base href.
A normalized URL is absolute from the URL host, includes the application's base href, and has no
trailing slash:
/my/app/user/123
is normalizedmy/app/user/123
is not normalized/my/app/user/123/
is not normalized
Example

Static Members
normalizeQueryParams(params: string) : string
Given a string of url parameters, prepend with '?' if needed, otherwise return parameters as is.
joinWithSlash(start: string, end: string) : string
Given 2 parts of a url, join them with a slash if needed.
stripTrailingSlash(url: string) : string
If url has a trailing slash, remove it, otherwise return url as is.
Class Details
path(includeHash?: boolean) : string
Returns the normalized URL path.
isCurrentPathEqualTo(path: string, query?: string) : boolean
Normalizes the given path and compares to the current normalized path.
normalize(url: string) : string
Given a string representing a URL, returns the normalized URL path without leading or trailing slashes.
prepareExternalUrl(url: string) : string
Given a string representing a URL, returns the platform-specific external URL path.
If the given URL doesn't begin with a leading slash ('/'
), this method adds one
before normalizing. This method will also add a hash if HashLocationStrategy
is
used, or the APP_BASE_HREF
if the PathLocationStrategy
is in use.
go(path: string, query?: string) : void
Changes the browsers URL to the normalized version of the given URL, and pushes a new item onto the platform's history.
replaceState(path: string, query?: string) : void
Changes the browsers URL to the normalized version of the given URL, and replaces the top item on the platform's history stack.
forward() : void
Navigates forward in the platform's history.
back() : void
Navigates back in the platform's history.
subscribe(onNext: (value: PopStateEvent) => void, onThrow?: (exception: any) => void, onReturn?: () => void) : Object
Subscribe to the platform's popState
events.
