js中让字符串中特定字符(数字标识)*显示 名字中间用*代替，电话中间加密，详细地址数字使用*

       //隐藏名字
    formatName = (name)=>{
        let newStr = '';
        if(name.length === 2){
            newStr = name.substr(0,1)+'*';
        }else if(name.length>2){
           let char = '';
           for(let i=0,len = name.length-2;i<len;i++){
                 char += '*';
           }
           newStr = name.substr(0,1)+char+name.substr(-1,1);
        }else{
            newStr = name
        }
          return newStr;
    }
    //隐藏电话
    formatTel = (tel)=>{
        tel = "" + tel;
        let newTel = tel.substr(0,3) + "****" + tel.substr(7)
        return newTel;
    }
    formatAddressX=(addr)=>{
        var nums = String(addr.match(/\d+(\.\d+)?(%)?(‰)?/g));
        var numArray = nums.split(',');
        var compare = function (x, y) {
            if (parseFloat(x) < parseFloat(y)) {
                return 1;
            } else if (parseFloat(x) > parseFloat(y)) {
                return -1;
            } else {
                return 0;
            }
        }
        //按数组的大小降序排列，很大程度上减少执行以下全局replace而带来的匹配不了问题
        numArray.sort(compare)
        for(var i=0; i<numArray.length;i++){
            var pattern = new RegExp(numArray[i],"gm");
            addr = addr.replace(pattern,"*");
        }
        return addr;
    }
