The "Code: [Select]" function in SMF 2 has for as long as I can remember always displayed "javascript:void(0);" at the bottom left of screen in Firefox/Chromium/Chrome (and probably others) but the function still worked .. ie. when you clicked on "Select" all the text in the code box got selected.
Now it does not, you still get the "javascript:void(0);" message, but clicking "Select" does nothing .. the text in the code box does not get selected.
This seems to be related to web browser version, as if I drop back to Firefox 51 the function works, but it does not work in Firefox 53.
[SMF 2.0.13]
(and this forum .. 2.0.14)

Does your site use HTTPS?
It does yes .. but as I said the function works in Firefox 51 and earlier versions of Chromium/Chrome. It just seems to be in recent browsers.
Here's an example:
https://forum.peppermintos.com/index.php/topic,5420.msg54342.html#msg54342
I was half expecting you to say no. Firefox has been changing its requirements so that higher or more sensitive features require HTTPS and potentially that would have been one of them. But it's not that.
Hmm, it still works on Chrome 57, and in Firefox 52, but you're right it's broken in FF 53. I wonder what they changed that broke.
You're also right, it's working here too in Chromium 57 .. so it appears to be just Firefox 53 where it's broken ???

}1366 is

Would need to be tested against Safari (incl. Mobile Safari) as well if it were changed, as well as older Firefox.
interesting that code is the same in SMF 2.1 but it does not have this issue.

1366 is oCurSelection.setBaseAndExtent(oCodeArea, 0, oLastChild, 'innerText' in oLastChild ? oLastChild.innerText.length : oLastChild.textContent.length);
If you replace
'innerText' in oLastChild ? oLastChild.innerText.length : oLastChild.textContent.length by
1 you'll see that Firefox selects the first line and Chromium more but not always the whole text (I assume something like "until the first closing double quote"). So it seems like this expression gives a node index out of range and different browsers count differently ...
As a
workaround you can switch back to the old behaviour for Firefox:
// Safari is special!
if (oCurSelection.setBaseAndExtent && !is_ff)
{setBaseAndExtent is supported in Firefox 53 (see release notes at developer.mozilla.org/en-US/Firefox/Releases/53) so I think this is why the behaviour changed in this version.
Code:[Select] now appears to be
broken in Chrome/Chromium 58 too .. at least on SMF 2.0.13 (but not here on 2.0.14 ???)

For clarity, this is WITHOUT
fugenkomponist's workaround .. which I only just spotted, and haven't tried yet as I'm assuming it's a Firefox specific workaround (?) but the problem now isn't.
I've seen this, and after looking through the code I see that this part:
// Safari is special!
if (oCurSelection.setBaseAndExtent)
{
var oLastChild = oCodeArea.lastChild;
oCurSelection.setBaseAndExtent(oCodeArea, 0, oLastChild, 'innerText' in oLastChild ? oLastChild.innerText.length : oLastChild.textContent.length);
}
Is intended for Safari, but since Firefox 52 they added this:"setBaseAndExtent"
I tested something by adding is_safari to that if, similar to the change fugenkomponist did but to check only for Safari instead filter out only Firefox, since that part is intended for Safari. That makes it work in Firefox 53 and Chrome 58 as intended.
The code looks like this:
// Safari is special!
if (oCurSelection.setBaseAndExtent && is_safari)
{
var oLastChild = oCodeArea.lastChild;
oCurSelection.setBaseAndExtent(oCodeArea, 0, oLastChild, 'innerText' in oLastChild ? oLastChild.innerText.length : oLastChild.textContent.length);
}
Those browsers are adding support for setBaseAndExtent but is broken, and all software that uses that is getting this errors.
Broken here too. I am on FF 53.
Has there been any change on this issue? I'm using SMF 2.14 and FF 54.0.1 (32-bit), and the select option is not working. It works in IE. My site is using HTTPS exclusively.
I'm using FF 54.0.1 (32-bit) and SMF 2.0.13 and the select option doesn't work either.
Looks like it's also broken on my iPhone with Safari.

Same thing
Any movement on this issue ?
It seems to be broken in both Firefox 55 and Chromium 60 .. although it is still working in Chrome 58 on this forum (SMF 2.0.14), but not on my forum (SMF 2.0.13) :-\

test here
I do not use the same code anymore but i encountered a similar issue with mine.
IIRC you should not use textContent.length which is the content length measured in characters BUT the number of text lines (number of nodes). It used to work even if the number used was superior but not anymore, you should use a number <= to the number of lines in the text being selected.
Try this
oCurSelection.setBaseAndExtent(oCodeArea, 0, oLastChild, oCodeArea.childElementCount);instead of
oCurSelection.setBaseAndExtent(oCodeArea, 0, oLastChild, 'innerText' in oLastChild ? oLastChild.innerText.length : oLastChild.textContent.length);Let me know if it works as i'm unable to test it right now.

That appears to work correctly.
Thanks a lot :)
It should work with most browsers (except the IEs before IE9)

Still broken. I've long given up on it being fixed. It seems to be something that isn't important enough to warrant a patch. I do see people posting possible fixes, though I don't think I have seen anyone post what actual file they propose changing. :)

The above change to [\Themes\default\scripts\script.js] works for a single line of code, but with a code section that has multiple lines it only selects the first line.
Single Line WorksMultiple Lines
Do not work.
Only selects line one
This should work fine with FF and Chrome
function smfSelectText(oCurElement, bActOnElement)
{
// The place we're looking for is one div up, and next door - if it's auto detect.
if (typeof(bActOnElement) == 'boolean' && bActOnElement)
var oCodeArea = document.getElementById(oCurElement);
else
var oCodeArea = oCurElement.parentNode.nextSibling;
if (typeof(oCodeArea) != 'object' || oCodeArea == null)
return false;
// Start off with my favourite, internet explorer.
if ('createTextRange' in document.body)
{
var oCurRange = document.body.createTextRange();
oCurRange.moveToElementText(oCodeArea);
oCurRange.select();
}
// Firefox at el.
else if (window.getSelection)
{
var oCurSelection = window.getSelection();
// Safari is special!
if (oCurSelection.selectAllChildren)
{
oCurSelection.selectAllChildren(oCodeArea);
}
else
{
var curRange = document.createRange();
curRange.selectNodeContents(oCodeArea);
oCurSelection.removeAllRanges();
oCurSelection.addRange(curRange);
}
}
return false;
}
Note
I replaced setBaseAndExtent by selectAllChildren because Chrome's behavior differs heavily from FF.
Indeed, according to setBaseAndExtent MDN (Mozilla) spec and introduced with FF 53
focusOffset
The number of child nodes from the start of the focus node that should be included in the selection. So for example, if the value is 0 the whole node is excluded. If the value is 1, the first child node is included. And so on.
If you got three lines of text in the code block there are 5 nodes: 3 for the text and two for the BRs, if you set focusOffset to 5 FF select all three lines
The official Spec, on which Chrome is based, is not that clear on what the focusOffset really is when both text nodes and tags are mixed within the content container. And clearly Chrome implemented it very differently from FF. So setBaseAndExtent is a no go at this time.

It's not a php file, it's script.js
Hy,
which js script?
the file name is script.js
Ok. I understand. I have an smf forum and the post does not work with the selection function and I thought it would explain ...
