const coloring = fn => ({ background, color = 'white' }) => (...text) => fn(`%c${text.join('')}`, `color:${color};background:${background}`); const colors = { primary: '#007bff', success: '#28a745', warning: '#ffc107', danger: '#dc3545', info: '#17a2b8', }; const dir = (key = '', value = {}) => { logs.primary(`++++++++++++start:${key}++++++++++++++`); console.dir(value); logs.primary(`++++++++++++end:${key}++++++++++++++`); }; const logs = Object.keys(colors) .reduce((prev, curr) => ({ ...prev, [curr]: coloring(console.log)({ background: colors[curr] }) }), { dir }); logs.success('hello succes'); logs.warning('hello fail');

在Chrome & Firefox(+31)中，您可以在console.log消息中添加CSS:

console.log('%c我的天哪!'， '背景:#222;颜色:# bada55 ');

同样适用于在同一命令中添加多个CSS。

模板系统，有用的，如果你想创建彩色的行文本，而不为每个块创建完整的风格

var tpl = 'background-color:greenyellow; border:3px solid orange; font-size:18px; font-weight: bold;padding:3px 5px;color:';
console.log('%cMagenta %cRed %cBlue', `${tpl} magenta`, `${tpl} Red`,`${tpl} #4274fb`);

我发现你可以使用ANSI颜色代码制作带有颜色的日志，这使得在调试中更容易找到特定的消息。试一试:

console.log( "\u001b[1;31m Red message" );
console.log( "\u001b[1;32m Green message" );
console.log( "\u001b[1;33m Yellow message" );
console.log( "\u001b[1;34m Blue message" );
console.log( "\u001b[1;35m Purple message" );
console.log( "\u001b[1;36m Cyan message" );

有一系列内置函数用于为控制台日志上色:

//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')

CSS格式说明符允许您自定义控制台中的显示。使用说明符开始字符串，并给出希望应用的样式作为第二个参数。

一个例子:

console.log("%cThis will be formatted with large, blue text", "color: blue; font-size: x-large");
