blocks|key|4511368|text|你可以先试试：angular.version.full。如果这不起作用，请尝试getAllAngularRootElements()[0].attributes["ng-version"]。原因是在角度1中，前者将起作用，而从角度2起，后者将起作用。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4511369|entityMap^0|7|K|13|1J|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

You could try: <code>angular.version.full</code> first. If this doesn't work, try <code>getAllAngularRootElements()[0].attributes["ng-version"]</code>. The reason being in Angular 1 the former will work and from angular 2 onwards the later will work.

If it's an online site you can use <a href="http://builtwith.com/" rel="noreferrer">http://builtwith.com/</a> and it usually can give you a good and useful bunch of information about that site.
However if they are using angular you can take a look at their page sources to see if they are using any attributes of angular like <code>ng-repeat</code> for example
You can also take a look at the sources that your browser get while browsing that site to see if <code>javascript</code> files for <code>angularjs</code> are included among the sources.

<a href="https://wappalyzer.com/" rel="nofollow noreferrer">https://wappalyzer.com/</a> 

is a good one too, and serve as a complement to builtwith. I don't think there is a limit of lookups, but the results are less detailed.

Those two used together may give you more insight.

It creates a small icon next to the URL bar that indicates whether or not it thinks the page was created using Angular, although I have not thoroughly tested its validity.

For Angular, in Chrome's inspector, in the Elements tab, inside the body element is an element called <code>app-root</code> containing <code>ng-version</code>, which shows the Angular version it's using.
