方法一:使用正则表达式,代码如下: function getByteLen(val) { var len = 0; for (var i = 0; i < val.length; i++) { var a = val.charAt(i); if (a.match(/[\u4e00-\u9fa5]/)) { len +=…
function getByteLen(val) { ; ; i < val.length; i++) { var a = val.charAt(i); if (a.match(/[^\x00-\xff]/ig) != null) { len += ; } else { len += 0.5; } } return len; } alert(getByteLen('aa7,.o哈'));…
