When I was working on an open source project, I used "angular-route": "^1.6.4", I found that after setting the href of the 3499910bf9dac5ae3c52d5ede7383485 tag, the path that appears after clicking is not #/, but #!#. However I did not set hashPrefix.

<a href="#about" class="ng-binding">About</a>

After clicking the label, the address bar will appear: http://localhost:9000/#!#about.

Print $location.

We found that the $location we set was not displayed in the path part of the pseudo URL as expected, but ran to the hash part.

The reason is: when the route version is >1.6.0, the default hashPrefix is ​​modified to ‘!’.

Equivalent to the following code

$locationProvider.hashPrefix('!');

There are two solutions provided below:

1. Restore hashPrefix to the version before 1.6 That way.

$locationProvider.hashPrefix('');

2. Change the format of href

<a href="#!about" class="ng-binding">About</a>

Another thing to note is that once ngRoute is introduced, the 3499910bf9dac5ae3c52d5ede7383485 tag will seem to have the default behavior overridden by ngRoute. , once the href starts with #, it will add a / to the hash part of the URL instead of appending the string directly to #, so something like 18b46262ad9db4792237c5069a8fe255 cannot jump to the id ="about" tag. I did some research and found that I can write an instruction and then call window.location.hash to solve this problem.

html

<a goto="#about" href="#about" class="ng-binding">About</a>

js

define(['app'], function (app) {
	app.directive('goto', function () {
		return function ($scope, $elem, $attrs) {
			$elem.click(function () {
				//console.log($attrs.goto.substring(1));
				window.location.hash = $attrs.goto.substring(1);
			});
		};
	});
});

Note: The above define is requireJS to define a module.
