This article describes how to implement full-width and half-width conversion in javascript. We will share this with you for your reference. The details are as follows:

Function fullChar2halfChar (str) {var result = ''; for (I = 0; I <str. length; I ++) {code = str. charCodeAt (I); // obtain the unicode code of the current character if (code >=65281 & code <= 65373) // In this unicode encoding range, all English letters have various characters {result + = String. fromCharCode (str. charCodeAt (I)-65248); // converts the unicode code of the full-width character to the unicode code of the corresponding half-width character} else if (code = 12288) // space {result + = String. fromCharCode (str. charCodeAt (I)-12288 + 32);} else {result + = str. charAt (I) ;}} return result ;}
