我自己弄明白后发现了这个帖子。以下是我的解决方案:

const testArray = {
  a: 1,
  b: 2
};
const verbose = true; //change this to false to turn off all comments
const consoleLog = (...message) => {
  return verbose ? console.log(...message) : null;
};

console.log("from console.log", testArray);
consoleLog("from consoleLog", testArray);
// use consoleLog() for the comments you want to be able to toggle.

如果你使用Webpack，你可以使用Terser插件来完全排除console.log函数调用。

这样你就可以有一个干净的生产应用程序包，它不会暴露不必要的信息，但在调试版本中仍然有所有这些信息。

https://github.com/terser/terser#compress-options

drop_console(默认值:false)——传递true以丢弃对控制台的调用。*功能。如果你希望删除一个特定的函数调用，如console.info和/或在删除函数调用后保留函数参数的副作用，则使用pure_funcs代替。

minimizer: [
    new TerserPlugin({
        terserOptions: {
            compress: {
                pure_funcs: [ 'console.log' ]
            }
        }
    }),
]

或者你也可以使用drop_console: true来排除所有控制台调用。

在脚本中重新定义console.log函数。

console.log = function() {}

够了，不再给控制台发消息了。

编辑:

扩展了Cide的想法。一个自定义记录器，您可以使用它从代码中切换登录。

从我的Firefox控制台:

var logger = function()
{
    var oldConsoleLog = null;
    var pub = {};

    pub.enableLogger =  function enableLogger() 
                        {
                            if(oldConsoleLog == null)
                                return;

                            window['console']['log'] = oldConsoleLog;
                        };

    pub.disableLogger = function disableLogger()
                        {
                            oldConsoleLog = console.log;
                            window['console']['log'] = function() {};
                        };

    return pub;
}();

$(document).ready(
    function()
    {
        console.log('hello');

        logger.disableLogger();
        console.log('hi', 'hiya');
        console.log('this wont show up in console');

        logger.enableLogger();
        console.log('This will show up!');
    }
 );

如何使用上面的“记录器”?在就绪事件中，调用记录器。disableLogger使控制台消息不被记录。向记录器添加调用。enabllogger和logger。在希望将消息记录到控制台的方法中的disableLogger。

当使用React时，你可以利用钩子来管理它，这样它就被限制在你的组件范围内

import { useEffect, useRef } from "react";

type LoggingReplacements = {
  debug?: typeof console["debug"];
  error?: typeof console["error"];
  info?: typeof console["info"];
  log?: typeof console["log"];
  warn?: typeof console["warn"];
};
/**
 * This replaces console.XXX loggers with custom implementations.  It will restore console log on unmount of the component.
 * @param replacements a map of replacement loggers.  They're all optional and only the functions defined will be replaced.
 */
export function useReplaceLogging({
  debug,
  error,
  info,
  log,
  warn,
}: LoggingReplacements): void {
  const originalConsoleDebug = useRef(console.debug);
  const originalConsoleError = useRef(console.error);
  const originalConsoleInfo = useRef(console.info);
  const originalConsoleLog = useRef(console.log);
  const originalConsoleWarn = useRef(console.warn);
  if (debug) {
    console.debug = debug;
  }
  if (error) {
    console.error = error;
  }
  if (info) {
    console.info = info;
  }
  if (log) {
    console.log = log;
  }
  if (warn) {
    console.warn = warn;
  }
  useEffect(() => {
    return function restoreConsoleLog() {
      console.debug = originalConsoleDebug.current;
      console.error = originalConsoleError.current;
      console.info = originalConsoleInfo.current;
      console.log = originalConsoleLog.current;
      console.warn = originalConsoleWarn.current;
    };
  }, []);
}

在https://github.com/trajano/react-hooks/tree/master/src/useReplaceLogging上编写测试代码

这是来自SolutionYogi和Chris s的答案的混合。它维护console.log行号和文件名。jsFiddle示例。

// Avoid global functions via a self calling anonymous one (uses jQuery)
(function(MYAPP, $, undefined) {
    // Prevent errors in browsers without console.log
    if (!window.console) window.console = {};
    if (!window.console.log) window.console.log = function(){};

    //Private var
    var console_log = console.log;  

    //Public methods
    MYAPP.enableLog = function enableLogger() { console.log = console_log; };   
    MYAPP.disableLog = function disableLogger() { console.log = function() {}; };

}(window.MYAPP = window.MYAPP || {}, jQuery));


// Example Usage:
$(function() {    
    MYAPP.disableLog();    
    console.log('this should not show');

    MYAPP.enableLog();
    console.log('This will show');
});
