您可以使用自定义样式表为调试器着色。如果您在WinXP中,可以将此代码放入

我在网站https://github.com/icodeforlove/console.js上写了模板颜色,让我们可以更轻松地完成这项工作。

我建议编写一个具有几个预定颜色(例如成功、错误、信息、警告、默认颜色)的函数,这些颜色将根据传递给函数的参数应用。
它提高了可读性,降低了代码的复杂性。它太容易维护,并根据您的需要进一步扩展。
下面给出的是一个javascript函数,您必须编写一次,然后才能使用它。一次又一次。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | function colorLog(message, color) { color = color ||"black"; switch (color) { case"success": color ="Green"; break; case"info": color ="DodgerBlue"; break; case"error": color ="Red"; break; case"warning": color ="Orange"; break; default: color = color; } console.log("%c" + message,"color:" + color); } |

默认颜色为黑色,在这种情况下,您不必将任何关键字作为参数传递。在其他情况下,您应该为期望的结果传递

对日志消息使用标记。
有一系列用于为控制台日志着色的内置函数:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //For pink background and red text console.error("Hello World"); //For yellow background and brown text console.warn("Hello World"); //For just a INFO symbol at the beginning of the text console.info("Hello World"); //for custom colored text console.log('%cHello World','color:blue'); //here blue could be replaced by any color code //for custom colored text with custom background text console.log('%cHello World','background:red;color:#fff') |

实际上,我只是偶然发现了这一点,对将要发生的事情感到好奇,但实际上您可以使用bash颜色标记来设置chrome中输出的颜色:
1 2 3 | console.log('\x1b[36m Hello \x1b[34m Colored \x1b[35m World!'); console.log('\x1B[31mHello\x1B[34m World'); console.log('\x1b[43mHighlighted'); |

谷歌已经记录了这一点https://developers.google.com/web/tools/chrome-devtools/console/console-write使用CSS设计控制台输出。
The CSS format specifier allows you to customize the display in the console. Start the string with the specifier and give the style you wish to apply as the second parameter.

从chrome 60中,他们在编写console.info时删除了蓝色文本颜色的功能,并在console api中做了许多更改。
如果您在es6模式中编写一个字符串文字,使用backticks``作为console.log()中的标识符(称为模板字符串),那么下面的方法可以为控制台输出着色。
1 2 | console.log(`%cToday date=>%c${new Date()}`,`color:#F74C2F`, `color:green`); // output :Today date (in red color) => Date (in green color) |
。
模板系统,如果要创建彩色线条文本而不为每个块创建完整样式,则很有用
1 2 | var tpl = 'background-color:greenyellow; border:3px solid orange; font-size:18px; font-weight: bold;padding:3px 5px;color:'; console.log('%cNo #1' + '.%cRed Text' + '%cBlue Text', tpl+'magenta', tpl+'red', tpl+'blue'); |
。
我最近想解决一个类似的问题,并构造了一个只对我关心的关键字着色的小函数,这些关键字很容易被周围的花括号
这很有魅力:
1 2 3 4 5 6 7 8 9 10 11 12 13 | var text = 'some text with some {special} formatting on this {keyword} and this {keyword}' var splitText = text.split(' '); var cssRules = []; var styledText = ''; _.each(splitText, (split) => { if (/^\{/.test(split)) { cssRules.push('color:blue'); } else { cssRules.push('color:inherit') } styledText += `%c${split} ` }); console.log(styledText , ...cssRules) |
。
从技术上讲,您可以使用switch/case语句交换if语句,以允许出于不同的原因使用多种样式。
Try this:
1 2 3 4 5 6 7 8 9 10 11 12 13 | var funcNames = ["log","warn","error"]; var colors = ['color:green', 'color:orange', 'color:red']; for (var i = 0; i < funcNames.length; i++) { let funcName = funcNames[i]; let color = colors[i]; let oldFunc = console[funcName]; console[funcName] = function () { var args = Array.prototype.slice.call(arguments); if (args.length) args = ['%c' + args[0]].concat(color, args.slice(1)); oldFunc.apply(null, args); }; } |

现在它们都是你想要的:
1 2 3 | console.log("Log is green."); console.warn("Warn is orange."); console.error("Error is red."); |
