node.js - React is not defined ReferenceError? I am using webpack and webpack-dev-server -


this jsx: 

 var react = require('react');   var reactdom = require('react-dom');   reactdom.render(     <h1>hello world</h1>,     document.getelementbyid('content')   )

i build webpack build/bundle.js &
import bundle.js index.html

index.html:

<!doctype html> <html>   <head>   ┊ <meta charset="utf-8">   ┊ <meta name="viewport" content="width=device-width">   ┊ <title></title>   </head>   <body>   ┊ <div id="content"></div>   ┊ <script src="./build/bundle.js" type="text/javascript" charset="utf-8"></script>   </body> </html>

but when ran webpack-dev-server, chrome console error:
bundle.js:57 uncaught referenceerror: react not defined
sure, have run npm install react
enter image description here

how can fix it?(-_-)ゞ゛

you should add app.js not .jsx

var react = require('react');   var reactdom = require('react-dom');   reactdom.render(     <h1>hello world</h1>,     document.getelementbyid('content')   )

jsx transpiled language, interpreted react components. so, there has react in app.js react components interpret jsx!!

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...
