如何快速方便地禁用我的代码中的所有console.log语句？ [英] How to quickly and conveniently disable all console.log statements in my code?

问题描述

有没有办法关闭我的JavaScript代码中的所有 console.log 语句，用于测试？

解决方案

在脚本中重新定义console.log函数。

  console.log = function（）{} 
  

就是这样，没有更多的消息要控制。

EDIT： b
$ b

扩大Cide的想法。

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！'）; 
} 
）; 
  

如何使用上述logger？在就绪事件中，调用logger.disableLogger，以便不记录控制台消息。在要将消息记录到控制台的方法中，将调用添加到logger.enableLogger和logger.disableLogger。

Is there any way to turn off all console.log statements in my JavaScript code, for testing purposes?

解决方案

Redefine the console.log function in your script.

console.log = function() {}

That's it, no more messages to console.

EDIT:

Expanding on Cide's idea. A custom logger which you can use to toggle logging on/off from your code.

From my Firefox console:

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!');
    }
 );

How to use the above 'logger'? In your ready event, call logger.disableLogger so that console messages are not logged. Add calls to logger.enableLogger and logger.disableLogger inside the method for which you want to log messages to the console.
