you could use this jquery webcam pluginand then send the image to php-zbarcode. It uses zbarwhich can read qrcodes. Note that the plugin requires flash.
您可以使用此jquery 网络摄像头插件，然后将图像发送到php-zbarcode。它采用zbar和可读取qrcodes。请注意，该插件需要闪存。
There is also jsqrcodewhich you could use to scan and interpret the QR Code, however this requires HTML5 for displaying the webcam output, and flash for capturing.
还有jsqrcode，你可以用它来扫描并解释QR码，然而这需要HTML5，用于显示输出摄像头和闪光灯捕捉。
