Is there any difference in behaviour of below URL.
I don’t know why the
& is inserted, does it make any difference ?
& is HTML for “Start of a character reference”.
& is the character reference for “An ampersand”.
¤t; is not a standard character reference and so is an error (browsers may try to perform error recovery but you should not depend on this).
If you used a character reference for a real character (e.g.
™) then it (™) would appear in the URL instead of the string you wanted.
(Note that depending on the version of HTML you use, you may have to end a character reference with a
;, which is why
&trade= will be treated as ™. HTML 4 allows it to be ommited if the next character is a non-word character (such as
=) but some browsers (Hello Internet Explorer) have issues with this).
HTML doesn’t recognize the
& but it will recognize
& because it is equal to
& in HTML
I looked over this post someone had made: http://www.webmasterworld.com/forum21/8851.htm
Another common error occurs when including a URL which contains an ampersand (“&”):
This is invalid:
This example generates an error for “unknown entity section” because the
"&"is assumed to begin an entity reference. Browsers often recover safely from this kind of error, but real problems do occur in some cases. In this example, many browsers correctly convert ©=3 to ©=3, which may cause the link to fail. Since 〈 is the HTML entity for the left-pointing angle bracket, some browsers also convert &lang=en to 〈=en. And one old browser even finds the entity §, converting §ion=2 to §ion=2.
So the goal here is to avoid problems when you are trying to validate your website. So you should be replacing your ampersands with
& when writing a URL in your markup.
Note that replacing
& is only done when writing the URL in HTML, where
"&"is a special character (along with “<” and “>”). When writing the same URL in a plain text email message or in the location bar of your browser, you would use
"&". With HTML, the browser translates
"&"so the Web server would only see
"&"in the query string of the request.
Hope this helps : )
That’s a great example. When
¤t is parsed into a text node it is converted to
¤t. When parsed into an attribute value, it is parsed as
If you want
¤t in a text node, you should write
¤t in your markup.
The gory details are in the HTML5 parsing spec – Named Character Reference State
if you’re doing a string of characters. make:
let linkGoogle = 'https://www.google.com/maps/dir/?api=1'; let origin = '&origin=' + locations + ',' + locations; aNav.href = linkGoogle + origin;
