JavaScript phone number Regular expression validation function [original]_ regular expression

Copy Code code as follows:

function Checkmobile () {
var smobile = Document.mobileform.mobile.value
if (!) ( /^1[3|4|5|8][0-9]\d{4,8}$/.test (Smobile))) {
Alert ("Not a full 11-digit cell phone number or the correct number of the top seven");
Document.mobileform.mobile.focus ();
return false;
}
}

The following is the cloud Habitat Community editors on the above regular expression of the simple analysis, with the increase in the number of mobile phone numbers, we can expand their own functions, do not know the regular friends read this article should be a point ah.
This is mainly the code, and later we modify this paragraph can be
^1[3|4|5|8][0-9]\d{4,8}$
^1 representative to start with 1, now China's mobile phone number is not the other beginning, later not necessarily AH
[3|4|5|8] immediately after the top 1, can be 3 or 4 or 5 or 8 of a number, if the next 190 start cell phone number, you need the following [3|4|5|8| 9]
[0-9] represents any number in the middle of 0-9, which can be 0 or 9
\d{4,8} This \d, like [0-9], is a number in the middle of 0-9. {4,8} represents the highest 8 digits of the previous minimum 4-digit number. Why here is not the direct 8, because the cell phone number attribution to the query, according to the first 7 can know the specific address, the following 4-bit has no impact.
Here is the test code:

<script type= "Text/javascript" > Function Checkmobile () {var smobile = Document.mobileform.mobile.value If (! (/^1[3|5][0-9]\d{4,8}$/.test (Smobile)) {Alert ("not a complete 11-digit cell phone number or the correct number of the top seven"); Document.mobileform.mobile.focus (); return false; } </script> <form action= "http://ip.jb51.net/sj/mobile2.asp" name= mobileform "method=" POST "onsubmit=" return Checkmobile (); " > <input name= "mobile" Class=tdc size= "maxlength=" > <input name= "Action" type= "hidden" value=mobile& Gt <input class=bdtj name=b1 type=submit value= "Query" > </FORM>

Below is the code that the cloud-dwelling community has found from other websites. Everyone can see. We also recommend that you learn the regular expression, a lot of places to leave the regular expression is really not.
\d represents a number
For example: 1 or 2 or 3, single digit
If more than one can use the \d*
\d{7,8} represents 7-8 digits (for phone numbers)
For example: 12345678
{7,8} represents a 7-bit or 9-digit number, and the general phone number is compliant.
\d{3,} represents extension number
For example: 123,12345
{3,} indicates a minimum of 3 digits and can be more
0\d{2,3} represents the area code
For example: 021
[0\+]\d{2,3} represents the international area code
If using a minus sign connection, the complete should be
/^ ([0\+]\d{2,3}-)? (0\d{2,3})? (\d{7,8}) (-(\d{3,}))? $/

Test code:

<script language= "JavaScript" > Function testit () {var filter=/^ ([0\+]\d{2,3}-)? 0\d{2,3})? (\d{7,8}) (-(\d{3,}))? $/; Alert (Filter.test (txt.value)); } </SCRIPT> <input id=txt onchange= "Testit ()" >
