Re: Browser HTML Source & URLs

[hh via use-livecode]

What you've seen is the difference of the htmltext of a browser
(also of a browser widget) and the *generated* htmltext.
The latter includes for example also parts that are generated by
JavaScript parts of the htmltext.

One of the best ideas Mark Waddingham ever had that he later abandoned 
was about ten years ago when he proposed adding "xmlText" as a synonym 
for "htmlText", flagging "htmlText" for eventual deprecation.


The best idea he never expressed having was calling the browser widget 
property "html" rather than "htmlText". Because that's what it is.


HTML is not htmlText.

Using that name for the field property hints at field capabilities that 
don't exist.


And then using that same name for the VERY different data in the browser 
object only makes a bad name worse.


I can understand why "htmlText" was used in the mid-90s when it was 
introduced, but it wasn't really a solid fit even then, and has become 
ever less like HTML every year since, causing ever more confusion.

Try this:

  put url tURL into tSource -- the source text
  set the htmlText of fld "HTMLText" to tSource -- LC's display

LC only supports a subset of HTML, so when you put the source into a 
field, only the supported parts go in. But you can grab the unadultered 
source first.

Look at the output in field HTMLTextField1.

Then go to the website with Safari with the Developer Menu turned on,
and use the pull down menu option for “Show Page Source”.

You will see there is a vast difference between what Safari shows
versus what LiveCode HTMLText shows.  (It’s less than useful!)

Your thoughts?

Re: Browser HTML Source & URLs

[Brian Milby via use-livecode]

Htmltext of a field is not the same as htmltext of the browser widget.  A 
LiveCode field only supports a fraction of html.  In your example you need to 
just set the text of the field to see the page source.  Setting htmetext forces 
LiveCode to render the html and anything it does not understand is stripped.

Thanks,
Brian

I thought it was the source code originally too,
but it doesn’t work correctly.

For example:

set the HTMLText of field "HTMLTextField1" to URL field "WebAddressField1" of 
this card
(Where field "WebAddressField1" of this card = http://www.duckduckgo.com 
 )

Look at the output in field HTMLTextField1.

Then go to the website with Safari with the Developer Menu turned on,
and use the pull down menu option for “Show Page Source”.

You will see there is a vast difference between what Safari shows
versus what LiveCode HTMLText shows.  (It’s less than useful!)

Your thoughts?

Re: Browser HTML Source & URLs

[Håkan Liljegren via use-livecode]

You can execute a small javascript to grab the HTML. I’ve done something 
similar in an Instagram Scraper I just built….

First you need to set up a callback function in the widget under javascript 
handlers e.g. jscallback then you can call a javascript that calls you back 
with whatever you want. Create field for the script, save script into a 
constant or just submit if it is short:

do ”liveCode.jscallback( ’source', document.documentElement.outerHTML );" in 
widget ”browser"

You also need to setup the jscallback in LiveCode:

on jscallback pMethod pValue
 if pMethod is ”source” then
      # pValue holds the source except the 
   end if
end jsCallback

Here I used a ”key value” principle with a method and a value, but you can of 
course set up several callbacks in the browser widget if you prefer.

Håkan
PS. Writing code directly in mail so it is untested and qoutes and formatting 
might be wrong...

The htmltext is the page source code. So

put the htmltext of widget "browser" into field 1
