This article mainly introduces the function of Fuzzy Matching IP addresses in javascript regular expressions, and demonstrates the implementation of JS Fuzzy Matching IP addresses in combination with simple examples, related Regular Expression identification and matching techniques for numbers and strings. For more information, see the example in this article. We will share this with you for your reference. The details are as follows:
Function checkip () {var strIP = document. getElementById ("accessip "). value; var re =/^ (\ d {1, 3} | \*)\. (\ d {1, 3} | \*)\. (\ d {1, 3} | \*)\. (\ d {1, 3} | \ *) $/g // The Regular Expression of fuzzy Match ip address if (re. test (strIP) {if (RegExp. $1 = '*' & RegExp. $2 = '*' & RegExp. $3 = '*' & RegExp. $4 = '*') {return true;} if (RegExp. $1 <256 & RegExp. $2 = '*' & RegExp. $3 = '*' & RegExp. $4 = '*') {return true;} if (RegExp. $1 <256 & RegExp. $2 <256 & RegExp. $3 = '*' & RegExp. $4 = '*') {return true;} if (RegExp. $1 <256 & RegExp. $2 <256 & RegExp. $3 <256 & RegExp. $4 = '*') {return true;} if (RegExp. $1 <256 & RegExp. $2 <256 & RegExp. $3 <256 & RegExp. $4 <256) {return true;} return false ;}
I hope this article will help you design JavaScript programs.
