If you are checking the browser use <code>$.browser</code>. But if you are checking feature support (recommended) then use <code>$.support</code>.

You should NOT use $.browser to enable/disable features on the page. Reason being its not dependable and generally just not recommended.

If you need feature support then I recommend <a href="http://www.modernizr.com/" rel="nofollow">modernizr</a>.

blocks|key|908126|text|显然，唯一可靠且被接受的解决方案是像这样进行特征检测：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|908127|browser_treats_urls_like_safari_does+=+false;
var+last_location_hash+=+location.hash;
location.hash+=+'"blah"';

Apparently the only reliable and accepted solution would be to do feature detection like this:

<pre><code>browser_treats_urls_like_safari_does = false;
var last_location_hash = location.hash;
location.hash = '"blah"';
if (location.hash == '#%22blah%22')
 browser_treats_urls_like_safari_does = true;
location.hash = last_location_hash;

A very useful way to fix this is to detect the browsers webkit version and check if it is at least the one we need, else do something else.

Using jQuery it goes like this:<div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>"use strict";

$(document).ready(function() {
 var appVersion = navigator.appVersion;
 var webkitVersion_positionStart = appVersion.indexOf("AppleWebKit/") + 12;
 var webkitVersion_positionEnd = webkitVersion_positionStart + 3;
 var webkitVersion = appVersion.slice(webkitVersion_positionStart, webkitVersion_positionEnd);
	
 console.log(webkitVersion);

 if (webkitVersion &lt; 537) {
 console.log("webkit outdated.");
 } else {
 console.log("webkit ok.");
 };
});</code></pre>
</div>
</div>


This provides a safe and permanent fix for dealing with problems with browser's different webkit implementations.

Happy coding!

Though both are Webkit based browsers, Safari urlencodes quotation marks in the URL while Chrome does not.

Therefore I need to distinguish between these two in JS.

<a href="http://api.jquery.com/jQuery.browser/" rel="noreferrer">jQuery's browser detection docs</a> mark "safari" as deprecated.

Is there a better method or do I just stick with the deprecated value for now?

Detect Safari using jQuery

Android

jQuery

虽然两者都是基于Webkit的浏览器，但Safari对URL中的引号进行了编码，而Chrome则不是。因此，我需要在JS中区分这两者。将"safari“标记为已弃用。有没有更好的方法，或者我现在只使用弃用的值？
