Java以及JS 手机号当中4位用“*”代替

<span style="font-family: Arial, Helvetica, sans-serif;">String mobile = "18888888888";</span>

if (mobile != null && !mobile.equals("")) {String usermobile1 = mobile.substring(0, mobile.length() -  (mobile.substring(3)).length()) + "****" + mobile.substring(7);}

上面是在java中把手机号当中4位用“*”代替

接下来在js中把手机号当中4位用“*”代替

var data = “18888888888”;var reg = /(\d{3})\d{4}(\d{4})/;var phonelulu = data.replace(reg,"$1****$2");
