Description
The test method checks whether a pattern exists in the string and returns true if it exists, otherwise it returns false.

Regular expression part:
d represents a number
{7,8} represents 7-8 digits (representing a phone number)
{3,} represents an extension number
d{2,3} represents the area code
]d{2,3} represents the international area code
^13d{5,9}$/ //130?139. At least 5 people, at most 9 people
/^153d{4,8}$/ //China Unicom 153. At least 4 digits, at most 8 digits
/^159d{4,8}$/ //Move 159. At least 4 digits, up to 8 digits

{
Common.WebMessage.showMsg(HttpContext.Current, "Please enter the correct phone number!");
return;
}
}
if (model.MobilePhone != null)
{
if (!Common.PageValidate.IsValidate(model.MobilePhone, "^0{0,1}(13[0- 9]|15[3-9]|15[0-2]|18[0-9])[0-9]{8}$"))
{
Common.WebMessage.showMsg(HttpContext .Current, "Please enter the correct 11-digit valid mobile phone number! ");
