javascript - how noscript tag treated in different browsers -


i can't see explanation anywhere.

i want know what browsers generate data inside noscript tag, if js enabled.

for example:

according html5 specs, allowed use noscript tag inside head tag.

<head> <noscript> <link rel="stylesheet" href="basic.css" type="text/css" media="all" /> </noscript> </head>

the reason i'm asking question i'm afraid browsers may treat noscript tag text(if js enabled), , result load/add unnecessarily data.

so, how browsers treat noscript tag?

thanks.

the html element defines section of html inserted if script type on page unsupported or if scripting turned off in browser. source.

also

the noscript element represents nothing if scripting enabled, , represents children if scripting disabled. used present different markup user agents support scripting , don't support scripting, affecting how document parsed. source.

noscript tag supported among browsers , far know there no deviation standard specification.

by way if need make sure of behavior across different browser can use web-based browser testing tools https://www.browserstack.com speed testing process.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
