Regular expressions in JavaScript using and verifying the regular _ regular expressions of QQ numbers

No more nonsense to say, directly to everyone paste regular expression code.

 function Myvalid () {
   var errormsg = "";
   var res = true;
   Get the value you want to validate.
   var receivename = $ ("#receiveName"). Val ();//Name
   var receivemobile = $ ("#tMobile"). Val ()/mobile number
   var Validcode = $ ( "#validCode"). Val ()//Verification code
   var regname =/^[\ue-\ufa]{,}$/;//authentication name
   var regmobile =/^[| | | | [-]\d{}$/;//Verification mobile phone
   var regcode =/^\d{}$/;//Authentication Code
   if (!regname.test (Receivename)) {
   errormsg = "name format is not correct; \ n \ r ";
   res = false;
   if (!regmobile.test (Receivemobile)) {
   errormsg + = "Cell phone number format is not correct; \n\r";
   res = false;
   if (!regcode.test (Validcode)) {
   errormsg = "Please enter a bit of digital verification code; \n\r"
   ; res = false;
   if (!res) {
   $.ligerdialog.error (errormsg, error hint);
   }
   return res;
 }

Share a very simple regular expression that verifies the QQ number.

The code is as follows:

[1-9] [0-9] {4,}
