你可以使用logeek，它可以让你控制你的日志消息的可见性。你可以这样做:

<script src="bower_components/dist/logeek.js"></script>

logeek.show('security');

logeek('some message').at('copy');       //this won't be logged
logeek('other message').at('secturity'); //this would be logged

你也可以使用logeek.show('nothing')来完全禁用每条日志消息。

这是在JS 2020中引入的。在浏览器上globalThis和window一样，在nodejs上globalThis和global一样等等。在任何环境上，它将直接指向全局对象，因此这段代码将在任何支持JS2020的env上工作了解更多信息:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis

对于任何现代浏览器& nodejs v12或更新版本，你应该使用这个:

globalThis.console.log = () => null;
globalThis.console.warn = () => null;
globalThis.console.info = () => null;
globalThis.console.error = () => null;

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

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。

我认为2020年最简单、最容易理解的方法是创建一个像log()这样的全局函数，你可以选择以下方法之一:

const debugging = true;

function log(toLog) {
  if (debugging) {
    console.log(toLog);
  }
}

function log(toLog) {
  if (true) { // You could manually change it (Annoying, though)
    console.log(toLog);
  }
}

你可以说这些功能的缺点是:

您仍然在运行时调用函数 您必须记住在第二个选项中更改调试变量或if语句 您需要确保在加载所有其他文件之前加载了该函数

And my retorts to these statements is that this is the only method that won't completely remove the console or console.log function which I think is bad programming because other developers who are working on the website would have to realize that you ignorantly removed them. Also, you can't edit JavaScript source code in JavaScript, so if you really want something to just wipe all of those from the code you could use a minifier that minifies your code and removes all console.logs. Now, the choice is yours, what will you do?

在我搜索了这个问题以及在我的cordova应用程序中尝试后，我只是想警告每个windows phone的开发者不要覆盖

    console.log

因为应用程序在启动时会崩溃。

如果你幸运的话，它不会崩溃，但在商店中提交它会导致应用程序崩溃。

只是覆盖

    window.console.log 

如果你需要的话。

这在我的应用程序工作:

   try {
        if (typeof(window.console) != "undefined") {
            window.console = {};
            window.console.log = function () {
            };
            window.console.debug = function () {
            };
            window.console.info = function () {
            };
            window.console.warn = function () {
            };
            window.console.error = function () {
            };
        }

        if (typeof(alert) !== "undefined") {
            alert = function ()
            {

            }
        }

    } catch (ex) {

    }
