1.判断类型汇合
export const checkStr = (str, type) => { switch (type) { case 'phone': //手机号码 return /^1[3|4|5|6|7|8|9][0-9]{9}$/.test(str); case 'tel': //座机 return /^(0\d{2,3}-\d{7,8})(-\d{1,4})?$/.test(str); case 'card': //身份证 return /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/.test(str); case 'pwd': //明码以字母结尾，长度在6~18之间，只能蕴含字母、数字和下划线 return /^[a-zA-Z]\w{5,17}$/.test(str) case 'postal': //邮政编码 return /[1-9]\d{5}(?!\d)/.test(str); case 'QQ': //QQ号 return /^[1-9][0-9]{4,9}$/.test(str); case 'email': //邮箱 return /^[\w-]+(\.[\w-]+)*@[\w-]+(\.[\w-]+)+$/.test(str); case 'money': //金额(小数点2位) return /^\d*(?:\.\d{0,2})?$/.test(str); case 'URL': //网址 return /(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])?/.test(str) case 'IP': //IP return /((?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d))/.test(str); case 'date': //日期工夫 return /^(\d{4})\-(\d{2})\-(\d{2}) (\d{2})(?:\:\d{2}|:(\d{2}):(\d{2}))$/.test(str) || /^(\d{4})\-(\d{2})\-(\d{2})$/.test(str) case 'number': //数字 return /^[0-9]$/.test(str); case 'english': //英文 return /^[a-zA-Z]+$/.test(str); case 'chinese': //中文 return /^[\\u4E00-\\u9FA5]+$/.test(str); case 'lower': //小写 return /^[a-z]+$/.test(str); case 'upper': //大写 return /^[A-Z]+$/.test(str); case 'HTML': //HTML标记 return /<("[^"]*"|'[^']*'|[^'">])*>/.test(str); default: return true; } }
2.严格的身份证校验
export const isCardID =(sId)=>{if (!/(^\d{15}$)|(^\d{17}(\d|X|x)$)/.test(sId)) {console.log('你输出的身份证长度或格局谬误')return false }//身份证城市 var aCity = { 11: "北京", 12: "天津", 13: "河北", 14: "山西", 15: "内蒙古", 21: "辽宁", 22: "吉林", 23: "黑龙江", 31: "上海", 32: "江苏", 33: "浙江", 34: "安徽", 35: "福建", 36: "江西", 37: "山东", 41: "河南", 42: "湖北", 43: "湖南", 44: "广东", 45: "广西", 46: "海南", 50: "重庆", 51: "四川", 52: "贵州", 53: "云南", 54: "西藏", 61: "陕西", 62: "甘肃", 63: "青海", 64: "宁夏", 65: "新疆", 71: "台湾", 81: "香港", 82: "澳门", 91: "国外" };if (!aCity[parseInt(sId.substr(0, 2))]) { console.log('你的身份证地区非法')return false}// 出生日期验证var sBirthday = (sId.substr(6, 4) + "-" + Number(sId.substr(10, 2)) + "-" + Number(sId.substr(12, 2))).replace(/-/g, "/"), d = new Date(sBirthday) if (sBirthday != (d.getFullYear() + "/" + (d.getMonth() + 1) + "/" + d.getDate())) { console.log('身份证上的出生日期非法') return false }// 身份证号码校验var sum = 0, weights = [7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2],codes = "10X98765432" for (var i = 0; i < sId.length - 1; i++) { sum += sId[i] * weights[i]; } var last = codes[sum % 11];//计算出来的最初一位身份证号码 if (sId[sId.length - 1] != last) { console.log('你输出的身份证号非法') return false }return true}
3.将阿拉伯数字翻译成中文的大写数字
export const numberToChinese = (num) => {var AA = new Array("零", "一", "二", "三", "四", "五", "六", "七", "八", "九", "十");var BB = new Array("", "十", "百", "仟", "萬", "億", "点", ""); var a = ("" + num).replace(/(^0*)/g, "").split("."), k = 0, re = "";for (var i = a[0].length - 1; i >= 0; i--) { switch (k) { case 0: re = BB[7] + re;break; case 4:if (!new RegExp("0{4}//d{" + (a[0].length - i - 1) + "}$") .test(a[0])) re = BB[4] + re;break;case 8:re = BB[5] + re; BB[7] = BB[5]; k = 0;break;}if (k % 4 == 2 && a[0].charAt(i + 2) != 0 && a[0].charAt(i + 1) == 0) re = AA[0] + re;if (a[0].charAt(i) != 0) re = AA[a[0].charAt(i)] + BB[k % 4] + re; k++; }if (a.length > 1) { re += BB[6]; for (var i = 0; i < a[1].length; i++) re += AA[a[1].charAt(i)];} if (re == '一十') re = "十";if (re.match(/^一/) && re.length == 3) re = re.replace("一", ""); return re;}
5.将数字转换为大写金额
export const changeToChinese = (Num) => { //判断如果传递进来的不是字符的话转换为字符 if (typeof Num == "number") { Num = new String(Num); }; Num = Num.replace(/,/g, "") //替换tomoney()中的“,” Num = Num.replace(/ /g, "") //替换tomoney()中的空格 Num = Num.replace(/￥/g, "") //替换掉可能呈现的￥字符 if (isNaN(Num)) { //验证输出的字符是否为数字 //alert("请查看小写金额是否正确"); return ""; }; //字符处理完毕后开始转换，采纳前后两局部别离转换 var part = String(Num).split("."); var newchar = ""; //小数点前进行转化 for (var i = part[0].length - 1; i >= 0; i--) { if (part[0].length > 10) { return ""; //若数量超过拾亿单位，提醒 } var tmpnewchar = "" var perchar = part[0].charAt(i); switch (perchar) { case "0": tmpnewchar = "零" + tmpnewchar; break; case "1": tmpnewchar = "壹" + tmpnewchar; break; case "2": tmpnewchar = "贰" + tmpnewchar; break; case "3": tmpnewchar = "叁" + tmpnewchar; break; case "4": tmpnewchar = "肆" + tmpnewchar; break; case "5": tmpnewchar = "伍" + tmpnewchar; break; case "6": tmpnewchar = "陆" + tmpnewchar; break; case "7": tmpnewchar = "柒" + tmpnewchar; break; case "8": tmpnewchar = "捌" + tmpnewchar; break; case "9": tmpnewchar = "玖" + tmpnewchar; break; } switch (part[0].length - i - 1) { case 0: tmpnewchar = tmpnewchar + "元"; break; case 1: if (perchar != 0) tmpnewchar = tmpnewchar + "拾"; break; case 2: if (perchar != 0) tmpnewchar = tmpnewchar + "佰"; break; case 3: if (perchar != 0) tmpnewchar = tmpnewchar + "仟"; break; case 4: tmpnewchar = tmpnewchar + "万"; break; case 5: if (perchar != 0) tmpnewchar = tmpnewchar + "拾"; break; case 6: if (perchar != 0) tmpnewchar = tmpnewchar + "佰"; break; case 7: if (perchar != 0) tmpnewchar = tmpnewchar + "仟"; break; case 8: tmpnewchar = tmpnewchar + "亿"; break; case 9: tmpnewchar = tmpnewchar + "拾"; break; } var newchar = tmpnewchar + newchar; } //小数点之后进行转化 if (Num.indexOf(".") != -1) { if (part[1].length > 2) { // alert("小数点之后只能保留两位,零碎将主动截断" ); part[1] = part[1].substr(0, 2) } for (i = 0; i < part[1].length; i++) { tmpnewchar = "" perchar = part[1].charAt(i) switch (perchar) { case "0": tmpnewchar = "零" + tmpnewchar; break; case "1": tmpnewchar = "壹" + tmpnewchar; break; case "2": tmpnewchar = "贰" + tmpnewchar; break; case "3": tmpnewchar = "叁" + tmpnewchar; break; case "4": tmpnewchar = "肆" + tmpnewchar; break; case "5": tmpnewchar = "伍" + tmpnewchar; break; case "6": tmpnewchar = "陆" + tmpnewchar; break; case "7": tmpnewchar = "柒" + tmpnewchar; break; case "8": tmpnewchar = "捌" + tmpnewchar; break; case "9": tmpnewchar = "玖" + tmpnewchar; break; } if (i == 0) tmpnewchar = tmpnewchar + "角"; if (i == 1) tmpnewchar = tmpnewchar + "分"; newchar = newchar + tmpnewchar; } } //替换所有无用汉字 while (newchar.search("零零") != -1) newchar = newchar.replace("零零", "零"); newchar = newchar.replace("零亿", "亿"); newchar = newchar.replace("亿万", "亿"); newchar = newchar.replace("零万", "万"); newchar = newchar.replace("零元", "元"); newchar = newchar.replace("零角", ""); newchar = newchar.replace("零分", ""); if (newchar.charAt(newchar.length - 1) == "元") { newchar = newchar + "整" } return newchar;}
