这个类库是干嘛的?

平时项目的开发难免遇到大量的逻辑判断,于是我将一些常用的判断封装成了一个js类库,judge.js是我用业余时间写的一个js判断类库,可以用来判断数据类型(isFunction,isObject,isJson,isArray等),判断浏览器内核,判断移动和PC端浏览器名称,判断用户设备类型(安卓设备,iOS设备等),判断安卓IOS系统版本和做一些存在性信息校验(邮箱,邮编,电话,手机等等),还可以用于断言。他的特点有:

  • 没有任何依赖
  • 支持 AMD & CommonJS
  • 轻量级(10kb)

judge.js一个用来做判断的js类库

  • 没有任何依赖
  • 支持 AMD & CommonJS
  • 轻量级(10kb)
$ npm install  
$ gulp compress  
DEMO:http://hawx1993.github.io/jud...

开始

使用npm安装judgejs
$ npm install judgejs 
使用bower 安装judgejs
$ bower install judgejs  

目录

使用方法

var judge = require('judgejs');

judge.version

=>0.7.0

可以用$来代替judge。例如:

require('../judge.js')

$.version;
=> 0.7.0

judge.isArrayLike(obj);

=>true

judge.isArrayLike(null);

平台判断
judge.kernel()

用于检测当前浏览器的内核(排版引擎),可以检测的类型如下:

webkit,gecko,trident,edge,opera
浏览器的内核分别用于检测Chrome浏览器,Firefox浏览器,IE浏览器,Edge浏览器和Opera浏览器

if(judge.kernel() == 'webkit'){...} //引号处不能出现空格等不规范写法
judge.platform()

检测用户当前设备,可以检测的类型如下:

android,iPad,ios,windowsPhone,mac,windows,linux,blackBerryandroidTablet

if(judge.platform() == "androidTablet"){...}

参数也如上所示,千万不能写错,不然检测就会出现错误。参数采用驼峰命名法

judge.browser()

检测当前浏览器类型,可以检测的类型如下:

"IE6","IE7","IE8", "IE9", "IE10", "IE11","firefox","edge","sougou","liebao","liebao mobile","weixin","uc","mobile uc","baidu browser","mobile baidu","mobile qqbrowser","qqbrowser","opera","miui browser","oppo browser","mobile safari","android chrome", "ios chrome","chrome", "safari","ios safari","Mbile IE各个版本"

如需匹配不同平台的浏览器,需用judge.platform()再做一次匹配,使用场景可以是:

1.如果没有传入参数,则返回浏览器的名称,如:

judge.browser();//你的浏览器是Chrome的话

=>Chrome

2.传入参数的情况下,返回布尔值,如:

judge.browser("isChrome");

=>true
参数如下所示,采用驼峰命名法:
"isFirefox","isIosChrome","isIpadSafari", "isEdge", "isSougou","isLiebao",
"isLiebaoMobile","isWeiXin","isUC", "isUCMobile", "isBaidu",
"isBaiduMobile", "isQQMobile","isQQBrowser", "isOpera", "isMiuiBrowser",
"isOppoBrowser","isAndroidChrome","isChrome","isIosSafari","isSafari"

其中UC浏览器采用固定大写的写法。由于有的移动端浏览器采用和浏览器不同的ua,所以不能共用(无法单纯加一个`judge.isMobile()` or `judge.platform()=='android'`)。

//IE
"isIE","isMobileIE+数字(如:isMobileIE10)","isIE+数字(6~11),如isIE10"

//for example
judge.browser("isIE11");//true,如果你的浏览器是IE11的话
