Today User:Zvn edited section "Removing elements". He changed this:

:''To move an element simply attach it in another place with <ttcode>appendChild()</ttcode> or <ttcode>insertBefore()</ttcode>.''

to this:

:''To move an element simply attach it in another place with <ttcode>appendChild()</ttcode> or <ttcode>insertBefore()</ttcode> and remove the original element with <ttcode>removeChild()</ttcode>.''

I am just a beginner javacoder, but I think that is wrong. There is no need to remove the item from the old position manually, that happens automatically when one has inserted it in a new position.

Line 83:

Hi! The documentation says, in the Ajax section, that "AJAX scripts cannot reach a page on a different server (for example, google.ca or en.wikisource.org from en.wikipedia.org". I'm writing a user script that requires making a query to a tool hosted in Toolforge. I thought this would not be possible (given what the documentation says), but I found that `$.ajax` is being able to fetch resources from it, as long as other server includes the appropriate CORS Allow-Origin headers. Am I misinterpreting the documentation? Or has this changed lately? Thanks! [[User:Diegodlh|Diegodlh]] ([[User talk:Diegodlh|talk]]) 16:02, 12 April 2022 (UTC)

:{{ping|Diegodlh}} I'm not sure where I heard about this, but it seems that CORS has not affected us yet; currently it is in logging mode. Furthermore, all Wikimedia domains are allowed. Try going to [[:testwiki:|Test Wikipedia]], and you will see this red error appearing in your browser console:<br />
:{{small|{{error|1=[Report Only] Refused to load the script '[URL]' because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' blob: 'self' meta.wikimedia.org *.wikimedia.org *.wikipedia.org *.wikinews.org *.wiktionary.org *.wikibooks.org *.wikiversity.org *.wikisource.org wikisource.org *.wikiquote.org *.wikidata.org *.wikivoyage.org *.mediawiki.org 'unsafe-inline'". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.}}}}

::Thanks, @[[User:NguoiDungKhongDinhDanh|NguoiDungKhongDinhDanh]]. I tried using the user script (which makes a request to toolforge.org) in Test Wikipedia and I'm getting a different error (although the request does succeed, as you say): `Content Security Policy: The page’s settings observed the loading of a resource at <nowiki>https://web2cit.toolforge.org/</nowiki> (“default-src”). A CSP report is being sent.`. The warning does not appear if the user script sends a request to en.wikipedia.org, for example.

::I wonder whether CSP will be enforced in the future (I hope *.toolforge.org is allowed as well). This may not be what the Ajax section of the User scripts guide is referring to, though: "AJAX scripts cannot reach a page on a different server (for example, google.ca or en.wikisource.org from en.wikipedia.org". I wonder whether it's safe to remove this from the docs. [[User:Diegodlh|Diegodlh]] ([[User talk:Diegodlh|talk]]) 18:43, 12 April 2022 (UTC)

:::{{ping|Diegodlh}} Unfortunately, toolforge may not be allowed according to {{phab|T304107#7787150}} and {{phab|T304151}}. For the time being, I think you can [[WP:BOLD|be bold]] and remove that sentence.

== Weird syntax ==

Is there a reason the code is written <code>document.editform.wpTextbox1.value = "{" + "{wikify}}\n\n" + document.editform.wpTextbox1.value;</code>? Why are the two left brackets separated? [[User:Dimpizzy|Dimpizzy]] ([[User talk:Dimpizzy|talk]]) 17:42, 20 January 2023 (UTC)

:Probably to keep {{t|wikify}}'s content from getting substituted into the code, which can happen if you don't wrap your scripts in

<syntaxhighlight lang="js">//<nowiki>

scriptGoesHere();

//</nowiki></syntaxhighlight>

::Ah ok, I just saw the sentence in the page after the code explaining why as well, and I came back here to delete this topic, but you were too quick! [[User:Dimpizzy|Dimpizzy]] ([[User talk:Dimpizzy|talk]]) 17:47, 20 January 2023 (UTC)
