Re: Couple of HTML questions

[Colin Holgate via use-livecode]

I found a small styled text editor that I could add my buttons to, and can now 
edit text and send it to a PHP script to store online. Then a LiveCode stack 
can retrieve those files.

One problem I ran into was getting all of the characters to survive the ordeal. 
I could successfully get the text from the HTML editor to the online file, by 
using escape(the html of the text), but LiveCode doesn’t seem to have escape or 
unescape. It does have URLDecode, but if I used URLEncode the text wouldn’t 
fully upload to the PHP script.

In the end I had to use a replaceText for each of the unicode characters that 
were in the downloaded text. So far those have been bullets, checkmarks, and 
ellipses, and I do these lines:

put replaceText(it,"%u2026","…") into newtext

put replaceText(newtext,"%u221A","√") into newtext

set the htmltext of fld  “rich text field" to replaceText(newtext,"%u2022","•")

I read the instructions more carefully, and the selected text does get posted.

I am using 9.6.3, wonder if the version matters?

Colin,

i my previous comment i posted a link to a html5 stack which posts the selected 
text of a field to a Livecode Server script. Posting should definitely work.

Re: Couple of HTML questions

[Colin Holgate via use-livecode]

I do see a message when trying the post, that says exception thrown, see 
JavaScript Console. There are too many error lines to be sure which one of them 
is important. I get no error when trying to set the style of the text, which 
makes me think that the field is a plain text field.

When I test the stack inside LiveCode, the style changes and the post are 
working.

Re: Couple of HTML questions

[Colin Holgate via use-livecode]

My PHP script is at an https location, so no problems there. Currently I had 
been trying to set the text style of the selection, I didn’t yet try setting 
the text style of a character range.

The post does seem to be failing though, and given that I don’t need any HTML5 
features, only a simple styled text editor that is able to post the styled text 
to a PHP script, I will try to find some free code for doing that. Or maybe 
work out how to do it myself!

Does anyone know of any HTML and Javascript code for editing styled text? I 
think I can figure out the JavaScript to post the innerHTML of a Div.

Re: Couple of HTML questions

[Sean Cole (Pi) via use-livecode]

Hi Colin,
If it is HTML5 deployment you are looking to do from LC, how time critical
is your project? At the moment, HTML5 deployment is still quite broken in
many ways. It may be best to wait until LC10 which is using a whole new
engine (which looks very promising).

That said, the current engine 'CAN' do what you have 'asked' for sure, both
'post tData to URL(tUrl)' and 'set the textstyle of char 10 to 20 of fld
"myField" to "bold"' (although that will depend on what texttype is already
in that field potentially - it can be a bit kooky at times).

Other things in html5 deployment you will run into that will most likely
frustrate a little.

Regarding 'post', note the following from the LC dictionary:
Cross-platform note: The HTML5 engine only supports HTTP and HTTPs
protocols. ((ie, you can't use file;//, ftp://, etc))
Cross-platform note: URLs fetched by the HTML5 engine from a domain other
than that of the hosting the page may be blocked by web browsers, unless
the server hosting the URL sets the "Access-Control-Origin" header
appropriately. ((But as you are likely hosting the PHP you will have
control over that))

If you run into any specific HTML5 deployment issues I'd be happy to help
you through if you want to PM me at all.

Sean

Re: Couple of HTML questions

[matthias rebbe via use-livecode]

Hi Colin,

just tried here with a Livecode Server script not with a php script.

Posting data from an Html5 stack to an url definitely works. 
(see https://livecode.dermattes.de/postmr/postmr.html 
) 

What i do not get working is setting the text style. Even if i set the style 
already in the IDE and built the html5 standalone the text style is reset to 
plain when the html5 stack is displayed in the browser.

Regards,
Matthias
