The example in this article describes the method of realizing full-width half-width conversion in JavaScript. Share it with everyone for your reference, the details are as follows:
function fullChar2halfChar(str) { var result = ''; for (i=0 ; i<str.length; i++) { code = str.charCodeAt(i);//获取当前字符的unicode编码 if (code >= 65281 && code <= 65373)//在这个unicode编码范围中的是所有的英文字母已经各种字符 { result += String.fromCharCode(str.charCodeAt(i) - 65248);//把全角字符的unicode编码转换为对应半角字符的unicode码 }else if (code == 12288)//空格 { result += String.fromCharCode(str.charCodeAt(i) - 12288 + 32); }else { result += str.charAt(i); } } return result; }
I hope this article will be helpful to everyone in JavaScript programming.
