37、判断类型集合

export const checkStr = (str, type) => { switch (type) { case ‘phone’: return /^1[3|4|5|6|7|8|9][0-9]{9}$/.test(str); case ‘tel’: return /^(0\d{2,3}-\d{7,8})(-\d{1,4})?$/.test(str); case ‘card’: return /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/.test(str); case ‘pwd’: return /^[a-zA-Z]\w{5,17}$/.test(str) case ‘postal’: return /[1-9]\d{5}(? !\d)/.test(str); case ‘QQ’: return /^[1-9][0-9]{4,9}$/.test(str); case ’email’: return /^[\w-]+(\.[\w-]+)*@[\w-]+(\. [\w-]+)+$/.test(str); case ‘money’: return /^\d*(? :\.\d{0,2})?$/.test(str); case ‘URL’: return /(http|ftp|https):\/\/[\w\-_]+(\. [\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?/.test(str) case ‘IP’: return /((?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(? :25[0-5]|2[0-4]\\d|[01]?\\d?\\d))/.test(str); case ‘date’: return /^(\d{4})\-(\d{2})\-(\d{2}) (\d{2})(? :\:\d{2}|:(\d{2}):(\d{2}))$/.test(str) || /^(\d{4})\-(\d{2})\-(\d{2})$/.test(str) case ‘number’: return /^[0-9]$/.test(str); case ‘english’: return /^[a-zA-Z]+$/.test(str); case ‘chinese’: return /^[\\u4E00-\\u9FA5]+$/.test(str); case ‘lower’: return /^[a-z]+$/.test(str); case ‘upper’: return /^[A-Z]+$/.test(str); case ‘HTML’: return /<(“[^”]*”|'[^’]*’|[^'”>])*>/.test(str); default: return true; } }
