                # Firebug記錄Javascript日志 你可以使用Firebug來生成日志。 這有助于我們調試web頁面并發現頁面的錯誤。 在Firefox瀏覽器中執行以下代碼: ``` <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Firefox測試頁面 - w3cschool菜鳥教程</title> </head> <body> <script type="text/javascript"> var a = "w3cschool"; var b = ".cc"; document.write(a,b); console.log(a + b); </script> </body> </html> ``` 使用Firefox瀏覽器打開以上代碼文件firefox-test.html,執行結果及日志記錄如下: ![firedug-console](https://box.kancloud.cn/2015-12-13_566d21d74b3ce.jpg)
