Adding a hash prefix at the config phase if it's missing - angularjs

I am now integrating phantom in my Angularjs-based web application.
This fine article says that I should call the $locationProvider.hashPrefix() method to set the prefix to '!' from SEO reasons(allow crawlers to intercept the _escaped_fragment component of the URL).
The problem is that I haven't though of the earlier, and some of my URLs look as following:
#/home.
I though perhaps there is a way that I can implant this '!' char into the begging of the URL programmatically(in case it is not already there) at the config function of the APP, instead having to edit a lot of markup manually.

I've had similar problem and manually (search/replace) went through all the links and fixed them.
The other problem I had was the external sites were using the old format i.e.
http://plinkplink.net/#/event/3
instead of the new format
http://plinkplink.net/#!/event/3
The fix I did for that is not strictly speaking angularjs idiomatic but it does the job. I've added this script to the header of my page. It simply redirects pages with # to pages with #!:
<script>
var loc = window.location.href
if (loc.indexOf("#") != -1 && loc.indexOf("#!") == -1 ){
window.location.href = loc.replace("#", "#!");
}
</script>
I hope it helps.

Are you linking to the # value? ie - <a href="#/my/page"> If so, you shouldn't be. You should be linking to the url without the # prefix and I believe it'll solve your issue.

angular automatically removes parameters form url

In my application i am passing parameters for controller and read it using javascript as below.
localhost:8080/app/conroller#parameter=value
now problem is if i open my conroller in url and than append #parameter=value than only it works.
but i want to put whole link in anchor tag.
and when i click outside application than it automatically reroute localhost:8080/app/conroller and don't accept parameters.Although when opening that url if i apped #parameter=value* part than it works perfect.
i am using html5mode = true.
i search lots of document but didnt find right solution for this.
Not exactly sure if I get what you are asking but I think this is what you are getting at:
href="/app/conroller#parameter=value" target="_self"
Try adding the target self.
If that doesn't work you could try setting a base url <base href="/"></base>
You could try using ? for the query parameter instead of the #

Allowing both html5 and hashbang mode

My question is similar to this one, but my goal is to make the hashbang URLs silently redirect to the html5Mode style. I mean, when
example.com/#!/hello
gets entered, it should be silently changed to
example.com/hello
in order for existing links to stay valid. Compatibility with old browsers doesn't matter (as AFAIK everything supported by angularjs 1.3 works with the html5Mode).
Maybe I'm just misunderstanding the answer, but I can't see it there. I've got the html5Mode working without problems, but I sort of want two in one.
That's how it's working in mine and I'm not doing anything special? If I type mysite.com/angularapp/#/accounts/29 using Chrome, it gets replaced with mysite.com/angularapp/accounts/29
My routing config contains:
function($locationProvider) {
$locationProvider.html5Mode(true).hashPrefix("");
}
I'm on Angular 1.2.21, I'm not sure if that behavior would have changed on 1.3.x.
You can do it manually in JS with something liek this:
window.location.replace(
window.location.href.replace(new RegExp("^([^?]+/)#!/(.*)$"),
function (all, s1, s2) {
return s1 + s2;
}
)
);

Angular is changing query string parameter

We are using DPS's PXPay to generate payments for our app.
On a successful transaction the url that is provided looks like

This is definitely the request that is coming into the browser. BUT what is displayed in my browser URL bar... and what angular reads for the "result" token is this...

If you look closely... the two '==' are being taken off the end of the "result" token string.
I've tested in non angular applications and this isn't happening. Why does angular do this and how do I prevent it?
Angular cannot handle == because of its $location's search parsing. Just visit : https://angularjs.org/?foo==123 and the url will change to https://angularjs.org/?foo=
The same will not happen on a non-angular page.
Solution: Either patch angular OR HTML encode the section after ?result=
Depending on what you're trying to do with the URL that is returned, it might be simpler to just set window.location directly instead of working through Angular. This bypasses the query-string parsing in $location that's stripping the double equals.

AngularJS appending path after url?

I'm new to AngularJS. So far I have been working with a page in root (/), and I haven't seen any issues with the navigation.
Now I added a path - "entries". I see AngularJS is appending the path again, so
http://localhost:9000/entries
becomes:
http://localhost:9000/entries#/entries
And also a request with parameters, like:
http://localhost:9000/entries?par1=a&par2=1
becomes:
http://localhost:9000/entries?par1=a&par2=1#/entries?par1=a&par2=1
I read: $location doc
But still I don't quite understand what's going on here. Is this correct behaviour? If not, how do I turn it off?
This is the correct behavior. Changing paths in angular does not actual correspond to a change in the URL itself, just the fragment (what comes after the #). This is how angular (and JS frameworks in general) keep track of your location and changes it without refreshing.

AngularJS: How to clear query parameters in the URL?

My AngularJS application needs to have access to the user's LinkedIn profile. In order to do that I need to redirect the user to a LinkedIn URL which contains a callback redirect_uri parameter which will tell LinkedIn to redirect the user back to my webapp and include a "code" query param in the URL. It's a traditional Oauth 2.0 flow.
Everything works great except that LinkedIn redirects the user back to the following URL:
http://localhost:8080/?code=XXX&state=YYY#/users/123/providers/LinkedIn/social-sites
I would like to remove ?code=XXX&state=YYY from the URL in order to make it clean. The user does not need to see the query parameters I received from LinkedIn redirect.
I tried $location.absUrl($location.path() + $location.hash()).replace(), but it keep the query params in the URL.
I am also unable to extract the query parameters, e.g. "code", using ($location.search()).code.
It seems like having ? before # in the URL above is tricking Angular.
I use
$location.search('key', null)
As this not only deletes my key but removes it from the visibility on the URL.
I ended up getting the answer from AngularJS forum. See this thread for details
The link is to a Google Groups thread, which is difficult to read and doesn't provide a clear answer. To remove URL parameters use
$location.url($location.path());
To remove ALL query parameters, do:
$location.search({});
To remove ONE particular query parameter, do:
$location.search('myQueryParam', null);
To clear an item delete it and call $$compose
if ($location.$$search.yourKey) {
delete $location.$$search.yourKey;
$location.$$compose();
}
derived from angularjs source : https://github.com/angular/angular.js/blob/c77b2bcca36cf199478b8fb651972a1f650f646b/src/ng/location.js#L419-L443
You can delete a specific query parameter by using:
delete $location.$$search.nameOfParameter;
Or you can clear all the query params by setting search to an empty object:
$location.$$search = {};
At the time of writing, and as previously mentioned by #Bosh, html5mode must be true in order to be able to set $location.search() and have it be reflected back into the window’s visual URL.
See https://github.com/angular/angular.js/issues/1521 for more info.
But if html5mode is true you can easily clear the URL’s query string with:
$location.search('');
or
$location.search({});
This will also alter the window’s visual URL.
(Tested in AngularJS version 1.3.0-rc.1 with html5Mode(true).)
Need to make it work when html5mode = false?
All of the other answers work only when Angular's html5mode is true. If you're working outside of html5mode, then $location refers only to the "fake" location that lives in your hash -- and so $location.search can't see/edit/fix the actual page's search params.
Here's a workaround, to be inserted in the HTML of the page before angular loads:
<script>
if (window.location.search.match("code=")){
var newHash = "/after-auth" + window.location.search;
if (window.history.replaceState){
window.history.replaceState( {}, "", window.location.toString().replace(window.location.search, ""));
}
window.location.hash = newHash;
}
</script>
If you want to move to another URL and clear the query parameters just use:
$location.path('/my/path').search({});
Just use
$location.url();
Instead of
$location.path();
If you are using routes parameters just clear $routeParams
$routeParams= null;
How about just setting the location hash to null
$location.hash(null);
if you process the parameters immediately and then move to the next page, you can put a question mark on the end of the new location.
for example, if you would have done
$location.path('/nextPage');
you can do this instead:
$location.path('/nextPage?');
I've tried the above answers but could not get them to work. The only code that worked for me was $window.location.search = ''
I can replace all query parameters with this single line: $location.search({});
Easy to understand and easy way to clear them out.
The accepted answer worked for me, but I needed to dig a little deeper to fix the problems with the back button.
What I noticed is that if I link to a page using <a ui-sref="page({x: 1})">, then remove the query string using $location.search('x', null), I don't get an extra entry in my browser history, so the back button takes me back to where I started. Although I feel like this is wrong because I don't think that Angular should automatically remove this history entry for me, this is actually the desired behaviour for my particular use-case.
The problem is that if I link to the page using <a href="/page/?x=1"> instead, then remove the query string in the same way, I do get an extra entry in my browser history, so I have to click the back button twice to get back to where I started. This is inconsistent behaviour, but actually this seems more correct.
I can easily fix the problem with href links by using $location.search('x', null).replace(), but then this breaks the page when you land on it via a ui-sref link, so this is no good.
After a lot of fiddling around, this is the fix I came up with:
In my app's run function I added this:
$rootScope.$on('$locationChangeSuccess', function () {
$rootScope.locationPath = $location.path();
});
Then I use this code to remove the query string parameter:
$location.search('x', null);
if ($location.path() === $rootScope.locationPath) {
$location.replace();
}
