取IP

        let url = 'http://123.234.123.111:80/www/ASRfiles/ts/Server/2021/3/25/1015.mp4'
        //取ip
        let newUrl = url.substr(url.indexOf('//') + 2, url.indexOf(':', url.indexOf(':') + 1) - (url.indexOf('//') + 2))
        //取ip前面的 http://
        let topUrl = url.substr(0, url.indexOf('//') + 2)
        //取ip后面的 :80/www/ASRfiles/ts/Server/2021/3/25/1015.mp4
        let bottomUrl = url.substr(url.indexOf(':', url.indexOf(':') + 1))
        console.log(topUrl + newUrl + bottomUrl == url) //true

取键值对

/**获取url问号"?"后面键值对
 * @param {String} url
 */
export const GetRequest = url => {
   
  // let url = window.location.href;
  let theRequest = {
   };
  if (url.indexOf("?") != -1) {
   
      let a =url.indexOf("?");
      let b;
      if(url.indexOf("#") != -1){
   
          b =url.indexOf("#");
          if(a>b){
   
              b= url.length
          }
      }
      let data=url.substring(a,b);
      let str = data.substr(1);
      let strs = str.split("&");
      for(let i = 0; i < strs.length; i ++) {
   
          theRequest[strs[i].split("=")[0]]=(strs[i].split("=")[1]);
      }
  }
  return theRequest;
}

手机号脱敏

    // 手机号 移动电话脱敏 158 **** 8888
    export function mobile (str) {
   
        if (!!str) {
   
            var pat = /(\d{3})\d*(\d{4})/;
            return str.replace(pat, '$1****$2');
        } else {
   
            return "";
        }
    }

电话号脱敏

    // 手机号 移动电话脱敏 010-*****07
    export function telphone (str) {
   
        if (!!str) {
   
            var pat = /(\d{4})\d*(\d{2})/;
            return str.replace(pat, '$1****$2');
        } else {
   
            return "";
        }
    }

身份证脱敏

    export function idCard (str) {
   
        if (!!str) {
   
            return str.replace(/(\w{4})\w*(\w{4})/, '$1********$2');
        } else {
   
            return ""
        }
    }

银行卡号脱敏

    export function bankCard (str) {
   
        if (!!str && str.length > 8) {
   
            return `${
     str.substring(0, 4)} ${
     "*".repeat(str.length - 8).replace(/(.{
     4})/g, `$1 `)}${
     str.length % 4 ? " " : ""}${
     str.slice(-4)}`;
        } else {
   
            return ""
        }
    }

校验身份证号

    /*校验15位或18位的身份证号码*/
    export function checkIdCardNo(idCardNo) {
   
        //15位和18位身份证号码的基本校验
        var check = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/.test(idCardNo);
        return check;
    }
