How would I write the entity name in HTML and not have it do its function? Example: I'm doing a tutorial and want to tell someone how to use the non-breaking space in their code ( ) So, how to actually write out "&" "n" "b" "s" "p" ";" but have it be fluid with no spaces?
You can use & instead of &
So will be
You will need to write out a part of the code, in this example, I'll use the ampersand. Instead of writing , write out the ampersand, &, and then write nbsp;. Your final result should be , which will display on the webpage.
You could simply use the HTML for the ampersand as in which would display what you're looking for, i.e.
JavaScript can be used to change the text of HTML element, below example adds non-blocking space entity character into span element.
<p>A common character entity used in HTML is the non-breaking space: <span id="myid"></span></p>
<script>
document.getElementById("myid").textContent= " ";
</script>

In HTML5, if you include <pre> for example on a paragraph text, the result won't display '<pre>' on the paragraph, and it will run the command <pre> on the words after it.
What I have to do display texts including signs like " " or <> on a text, without running the command.
How can I accomplish this?
What you're looking for are known as HTML entities: characters that are reserved, and which automatically get parsed to the the relevant HTML. Using these tags allow you to write out the entities that would usually automatically get parsed as HTML.
For example, attempting to write out the <pre> tag within a parent <pre> tag will normally result in the inner tag being treated as HTML:
<pre><pre>The relevant tags surround this text</pre></pre>
Though using the HTML entities < and > for the left and right bracket respectively parses the entities as HTML, where they get displayed as text:
<pre><pre>The relevant tags surround this text</pre></pre>
A full list of HTML entities can be found here.
Hope this helps! :)
The 'best' way is to replace every < and > element with < and >:
But if you want to do it fast, you can use the xmp tag. It's deprecated but is still supported by all browsers
<xmp>
<div>Lorem ipsum</div>
<p>Hello</p>
</xmp>

You need to escape the provided content to display it as-is, without it being interpreted as HTML.
https://github.com/sindresorhus/escape-goat
This involves taking the reserved characters for the given language (e.g. HTML) and converting them to a representation that either uses an escape sequence or only uses unreserved characters.
In this case, HTML prescribes the use of entities to display characters that would otherwise be used by the syntax for tags and attributes within the source code itself.
If I write in a HTML file the browser automatically translates it to its corresponding character, in this case a space.
How can I escape from this phase? I mean, if I would like to print just the code (i.e. ) how can I prevent the browser from doing that?
You can't stop the browser from treating HTML as HTML.
If you want to include a & as data instead of as the start of a character reference, then use the character reference for it:
For this you will need JQuery.
Try .text() method. http://api.jquery.com/text/
Get the body content an then replace it with text.
Means: $('body').text($('body').html());.
This will give you an output of your html in plain Text. Actually you can do this with other Elements as well. Replace the Word body with the element, class or id you need.
I would like to paste into my HTML code a phrase
"<car>"
and I would like that this word "car" will be between <>. In some text will be
"<car>"
and this is not a HTML expression. The problem is that when I put it the parser think that this is the HTML syntax how to avoid it. Is there any expression which need to be between this?
replace < by < and > by >
Live on JSFiddle.
< and > are special characters, more special characters in HTML you can find here.
More about HTML entities you can find here.
use > for > and < for <
$gt;car<
you need to use special character .. To know more about Special Character link here
CODE:
<p>"<car >"</p>
OUTPUT:
"<car>"
< = < less than
> = > greater than
The same applies for XML too. Take a look here, special characters for HTML.
If you really want LESS THAN SIGN “<” to appear visibly in page content, write it as &, so that it will not be treated as starting a tag. Ref.: 5.3.2 Character entity references in HTML 4.01.
So you would write
<car>
If you like, you can write “>” as > for symmetry, but there is no need to.
But if you really want to put something in angle brackets, e.g. using a mathematical notation, rather than a markup notation (as in HTML and XML), consider using U+27E8 MATHEMATICAL LEFT ANGLE BRACKET “⟨” and U+27E9 MATHEMATICAL RIGHT ANGLE BRACKET “⟩”. They cause no problems to HTML markup, as they are not markup-significant. If you don’t know how to type them in your authoring environment, you can use character references for them:
⟨car⟩
This would result in ⟨car⟩, though as always with less common special characters, you would need to consider character (font) problems.
You can use the "greater than" and "less than" entities:
<car>
The W3C, the organization responsible for setting web standards, has some pretty good documentation on HTML entities. They consist of an ampersand followed by an entity name followed by a semicolon (&name;) or an ampersand followed by a pound sign followed by an entity number followed by a semicolon (&#number;). The link I provided has a table of common HTML entities.
With HTML I notice some libraries escape '. My question is why? The first time I thought maybe they did it just because but I seen more then one do it but not all. I can't remember what I looked at from the top of my head but the others i remember were &, <, >, ".
I know & is used for escape characters (such as to make & which is &). < and > are escaped to not be confused for start/end tags and " is done so you can put " in tag attributes if you need to for some reason. But why '? Also am I missing any other characters that should be escaped?
Because under HTML, the single-quote character ' can be used to delimit element attributes instead of the double-quote, like so:
<p class='something'></p>
However the character does not need to be escaped normally, but it's best to be safe.
In HTML, " and ' are interchangeable. Both can be used for setting the attribute for an element as well as used for denoting a string in JavaScript:
<img src="bob.png" />
<img src='bob.png' />
The single-quote mark is escaped because it can only be used as-is in certain contexts. When writing an escaping function, it is easier and faster to just always escape it, so you don't have to take into account the context.
For example, if you use double quotes " to denote an attribute value, you can use a single quote ' within it safely. However, if you use single quotes to denote the attribute value, you cannot.
I am having trouble understanding how escaping works inside html tag attribute values that are javascript.
I was lead to believe that you should always escape & ' " < > . So for javascript as an attribute value I tried:
It doesn't work. However:
and
does work in all browsers!
Now I am totally confused. If all my attribute values are enclosed in double quotes, does this mean I do not have to escape single quotes? Or is apos and ascii 39 technically different characters? Such that javascript requires ascii 39, but not apos?
There are two types of “escapes” involved here, HTML and JavaScript. When interpreting an HTML document, the HTML escapes are parsed first.
As far as HTML is considered, the rules within an attribute value are the same as elsewhere plus one additional rule:
The less-than character < should be escaped. Usually < is used for this. Technically, depending on HTML version, escaping is not always required, but it has always been good practice.
The ampersand & should be escaped. Usually & is used for this. This, too, is not always obligatory, but it is simpler to do it always than to learn and remember when it is required.
The character that is used as delimiters around the attribute value must be escaped inside it. If you use the Ascii quotation mark " as delimiter, it is customary to escape its occurrences using " whereas for the Ascii apostrophe, the entity reference ' is defined in some HTML versions only, so it it safest to use the numeric reference ' (or ').
You can escape > (or any other data character) if you like, but it is never needed.
On the JavaScript side, there are some escape mechanisms (with \) in string literals. But these are a different issue, and not relevant in your case.
In your example, on a browser that conforms to current specifications, the JavaScript interpreter sees exactly the same code alert('Hello');. The browser has “unescaped” ' or ' to '. I was somewhat surprised to hear that ' is not universally supported these days, but it’s not an issue: there is seldom any need to escape the Ascii apostrophe in HTML (escaping is only needed within attribute values and only if you use the Ascii apostrophe as its delimiter), and when there is, you can use the ' reference.
' is not a valid HTML reference entity. You should escape using '
