How to properly use same text sections across multiple html pages? - html

I am making help content documentation for an already made software (the kind of which opens in every software when you press F1 or navigate to the Help section in the menu bar). I am using simple html/CSS/js pages to do so.
There is a ton of the same text descriptions of various software properties that appear in more than one page. The idea is to make a single text source file, where all the text descriptions are located and then use some sort of referencing to that specific text section wherever necessary.
Kind of a similar to using a CSS stylesheet to apply styles over all of the pages, only this handles text instead of styles. This way I would be able to change text in only one file and it would apply everywhere it is used.
I ran across the html SSI method, but this only includes the entire html page and not just a specific text section the way I would like to. I would strongly avoid using different file for each text section.
Can anyone please point me into the right direction here?


I think that you can make a JavaScript function that contains the common texts and use this functions in your code whenever you need them, for this the JavaScript that you create should be an external file and you can reference it in every html page you need it.
For example, you can have one function that returns "Hello World" and set this to a "p" element with the id="title". So in every page where you have an element with the id title you can call your JavaScript function to set its text to "Hello World". Use this link to find out more about this topic:

UPDATE: I did a little test, i created the following JavaScript:
function helloTitle(){
var text = "Hello World!";
document.getElementById("title").innerHTML = text;
}
And referenced it in some HTML pages like this:
<script src="commonText.js" type="text/javascript"></script>
After that i only need to call the function in the element i want it to modify:
<p id="title"><script>helloTitle();</script></p>
This is a solution if you are only using JS, CSS and HTML. There should be other ways to achieve this.
Hope this information could help you!


I figured out how to do it a little more comforatbly on a large scale using the html command https://www.w3schools.com/tags/tag_iframe.asp
in your main html file you do:
<p> <iframe src="Text.html" width="100%" height="300" style="border:1px solid black;"> </p>
and then with some basic html formating insert whatever text u want
<html>
<body>
hmm idk what i should put here. Test
</body>
</html>
there will also be some css formatting needing to be done before it look perfect, but if you want to make multi line blocks I think this is the easiest way to.

Getting a HTML template as a HTML string

consider that I have several HTML templates and they have custom HTML tags. For ex: c-icon, c-text, c-button etc.
For some usecase(Display other content along with innerHTML), I need to access c-icon tag HTML inside c-text and append it to some text so that I can render it with some other html text. In future, I may have another component called c-badge and even I want to refer and render.
Could you please provide any suggestions for achieving the same?

Image embedded inside html, but with image data not inline

Is there a ('newbie-simple') way to embed an image inside html, however not in the inline form as usual:
<img src="data:image/png;base64,iVBORw0KGgoAAAA [...]" />
but in a form where the base64 code is placed on the end of the html file?
A possible benefit of this method would be that an image can be inserted in the page on more than one place using the same image data from the bottom of the html file.

TL;DR: With pure HTML/CSS - unfortunately no.
I need that too for Sciter Notes project to save notes (plain HTML files) with embedded images.
Ideally you should be able to do something like this:
<img src="cid:1234" />
...
<data id=1234 type="image/png" base64>
iVBORw0KGgoAAAA...
</data>
but unfortunately no such mechanism yet.
But you can implement schema explained above with script though.

If you are using HTML5, then you do not have to worry about caches. The browser will load all images and store them into an image-list, therefore the image will be loaded only once and reused at every place the key (the URL to the source image) is found.
The only thing you will have to do, if you are only using HTML, is to copy the URL of the image into every place you need to use it. This is necessary, because you cannot declare variables in HTML and hence cannot change them from another place in the document. For this purpose you would need additionally javascript for example.
Then you can go ahead with CSS to adjust the pictures to your requirements. Yu can either define classes in the header and let the img tags have these classes, or you can type the style properties inline or you can import an external CSS-file.
EDIT:
An example with javascript would be to add this code in
<body>
<img id="img" src="myIMG.jpg">
<script type="text/javascript">
function changeImage(id, src) {
document.getElementById(id).src=a;
}
</script>
</body>
Here the function changeImage is declared now. You can call this function either via onclick or inside of the script tag. You can address the correct image through its ID as first parameter (you will have to give every image its ID, don't confuse it with the image-list of your browser, here you define the ID in the img-tag) and the new source url as second parameter.

Extract raw text/data from a Google Sheet to a HTML Webpage

I have a basic website in which I intend to fill with a large amount of informative text. I wish to separate the content from the actual source code I use so my code is more efficient and organised. How do I go about doing this?
I tried publishing my Google sheet and using the code:
<div class="content_text">
<iframe src="https://docs.google.com/spreadsheets/d/1Th2gcOG92xex39mE_Ql0cYqN3I6BFPPQ-KQRUk-z48I/pubhtml?gid=0&single=true&widget=false&headers=false">
</iframe>
</div>
However this left me with:
Is there a way to eliminate the formatting to leave me with just the raw text?

There are a few undocumented parameters, you just need to modify the URL in the code adding the parameter chrome=false removes the title bar and gridlines=false will remove the borders. Your URL should look like this:
https://docs.google.com/spreadsheets/u/1/d/1Th2gcOG92xex39mE_Ql0cYqN3I6BFPPQ-KQRUk-z48I/pubhtml?gid=0&single=true&chrome=false&gridlines=false
Just replace the URL in the src attribute of your iframe tag.

Meteor {{#markdown}}

I am making a forum with markdown support.
I've been using meteor's markdown parser {{#markdown}} and have found something disturbing that I can't seem to figure out.
I am using {{#markdown}}{{content}}{{/markdown}} to render the content inserted into database.
The disturbing thing, for example, if someone writes up html without inserting it into the code block in the content...
example
<div class = "col-md-12">
Content Here
</div>
This will render as a column. They could also make buttons and etc through writing the HTML for it.
How to disable this behaviour so that when HTML is written it will not render into HTML but just simply show it as text?

You can write global helper, which will strip all html tags:
function stripHTML(string){
s = string.replace(/(<([^>]+)>)/ig, '');
return s;
}
Template.registerHelper('stripHTML', stripHTML)
Usage :
{{#markdown}}{{stripHTML content}}{{/markdown}}
Test it in console:
stripHTML("<div>Inside dive</div> Text outside")

HTML tag that causes other tags to be rendered as plain text [duplicate]

This question already has answers here:
How to display raw HTML code on an HTML page
(30 answers)
Closed 3 years ago.
I'd like to add an area to a page where all of the dynamic content is rendered as plain text instead of markup. For example:
<myMagicTag>
<b>Hello</b> World
</myMagicTag>
I want the <b> tag to show up as just text and not as a bold directive. I'd rather not have to write the code to convert every "<" to an "<".
I know that <textarea> will do it, but it has other undesirable side effects like adding scroll bars.
Does myMagicTag exist?
Edit: A jQuery or javascript function that does this would also be ok. Can't do it server-side, unfortunately.

You can do this with the script element (bolded by me):
The script element allows authors to include dynamic script and data blocks in their documents.
Example:
<script type="text/plain">
This content has the media type plain/text, so characters reserved in HTML have no special meaning here: <div> ← this will be displayed.
</script>
(Note that the allowed content of the script element is restricted, e.g. you can’t have </script> as text content (it would close the script element).)
Typically, script elements have display:none by default in browser’s CSS, so you’d need to overwrite that in your CSS, e.g.:
script[type="text/plain"] {display:block;}

You can use a function to escape the < >, eg:
'span.name': function(){
return this.name.replace(/</g, '<').replace(/>/g, '>');
}
Also take a look at <plaintext></plaintext>. I haven't used it myself but it is known to render everything that follows as plain text(by everything i mean to say it ignores the closing tag, so all the following code is rendered as text)

The tag used to be <XMP> but in HTML 4 it was already deprecated. Browser's don't seem to have dropped its support but I would not recommend it for anything beyond quick debugging. The MDN article about <XMP> lists two other tags, <plaintext> and <listing>, that were deprecated even earlier. I'm not aware of any current alternative.
Whatever, the code to encode plain text into HTML is pretty straightforward in most programming languages.
Note: the term similar means exactly that—all three are designed to inject plain text into HTML. I'm not implying that they are synonyms or that they behave identically—they don't.

There is no specific tag except the deprecated <xmp>.
But a script tag is allowed to store unformatted data.
Here is the only solution so far showing dynamic content, as you wanted.
Run code snippet for more info.
<script id="myMagicTag" type="text/plain" style="display:block;">
<b>Hello</b> World
</script>
Use Visible Data-blocks
<script>
document.querySelector("#myMagicTag").innerHTML = "<b>Unformatted</b> dynamic content"
</script>

No, that's not possible, you need to HtmlEncode it.
If your using a server-side language, that's not really difficult though.
In .NET you would do something like this:
string encodedtext = HttpContext.Current.Server.HtmlEncode(plaintext);

In my application, I need to prevent HTML from rendering
"if (a<b || c>100) ..."
and
"cout << ...".
Also the entire C++ code region HTML must pass through the GCC compiler with the desired effect. I've hit on two schemes:
First:
//<xmp>
#include <string>
//</xmp>}
For reasons that escape me, the <xmp> tag is deprecated. I find (2016-01-09) that Chrome and FF, at least, render the tag the way I want. While researching my problem, I saw a remark that <xmp> is required in HTML 5.
Second, in <head> ... </head>, insert:
<style type="text/css">
textarea { border: none; }
</style>
Then in <body> ... </body>, write:
//<br /> <textarea rows="4" disabled cols="80">
#include <stdlib.h>
#include <iostream>
#include <string>
//</textarea> <br />
Note: Set "cols="80" to prevent following text from appearing on the right. Set "rows=..." to one more line than you enclose in the tag. This prevents scroll bars. This second technique has several disadvantages:
The "disabled" attribute shades the region
Incomprehensible, complex comments in the code sent to the compiler
Harder to understand
More typing
However, this methhod is neither obsolete nor deprecated. The gods of HTML will make their faces to shine unto you.
