我写了一个ES2015解决方案(仅用于Webpack)。

class logger {
  static isEnabled = true;

  static enable () {
    if(this.constructor.isEnabled === true){ return; }

    this.constructor.isEnabled = true;
  }

  static disable () {
    if(this.constructor.isEnabled === false){ return; }

    this.constructor.isEnabled = false;
  }

  static log () {
    if(this.constructor.isEnabled === false ) { return; }

    const copy = [].slice.call(arguments);

    window['console']['log'].apply(this, copy);
  }

  static warn () {
    if(this.constructor.isEnabled === false ) { return; }

    const copy = [].slice.call(arguments);

    window['console']['warn'].apply(this, copy);
  }

  static error () {
    if(this.constructor.isEnabled === false ) { return; }

    const copy = [].slice.call(arguments);

    window['console']['error'].apply(this, copy);
  }
}

描述:

Along with logger.enable and logger.disable you can use console.['log','warn','error'] methods as well using logger class. By using logger class for displaying, enabling or disabling messages makes the code much cleaner and maintainable. The code below shows you how to use the logger class: logger.disable() - disable all console messages logger.enable() - enable all console messages logger.log('message1', 'message2') - works exactly like console.log. logger.warn('message1', 'message2') - works exactly like console.warn. logger.error('message1', 'message2') - works exactly like console.error. Happy coding..

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。

我写了一个ES2015解决方案(仅用于Webpack)。

class logger {
  static isEnabled = true;

  static enable () {
    if(this.constructor.isEnabled === true){ return; }

    this.constructor.isEnabled = true;
  }

  static disable () {
    if(this.constructor.isEnabled === false){ return; }

    this.constructor.isEnabled = false;
  }

  static log () {
    if(this.constructor.isEnabled === false ) { return; }

    const copy = [].slice.call(arguments);

    window['console']['log'].apply(this, copy);
  }

  static warn () {
    if(this.constructor.isEnabled === false ) { return; }

    const copy = [].slice.call(arguments);

    window['console']['warn'].apply(this, copy);
  }

  static error () {
    if(this.constructor.isEnabled === false ) { return; }

    const copy = [].slice.call(arguments);

    window['console']['error'].apply(this, copy);
  }
}

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.

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');
});

我的全面解决方案禁用/覆盖所有控制台。*函数在这里。

当然，请确保在检查必要的上下文之后包含它。例如，只包含在产品版本中，它不会轰炸任何其他关键组件等。

这里引用一下:

“使用严格的”; (() => { Var控制台=(窗口。控制台=窗口。控制台|| {}); ［ “维护”、“清楚”、“数”、“调试”,“dir”、“dirxml”, "error"， "exception"， "group"， " groupcollapse "， "groupEnd"， "info"， "log"， "markTimeline"， "profile"， "profileEnd"， "table"， "time" "timeEnd" "timeStamp" "trace" "warn" ]。forEach(方法=> { Console [method] = () => {}; })； console.log("此消息不应该在控制台日志中可见"); })（);
