标题:javascript截取中英文字符串、标点符号无乱码的例子
正文:
代码如下:<script> function subString(str, len, hasDot) { var newLength = 0; var newStr = ""; var chineseRegex = /[^\x00-\xff]/g; var singleChar = ""; var strLength = str.replace(chineseRegex,"**").length; for(var i = 0;i < strLength;i++){ singleChar = str.charAt(i).toString(); if(singleChar.match(chineseRegex) != null){ newLength += 2; }else{ newLength++; } if(newLength > len){ break; } newStr += singleChar; } if(hasDot && strLength > len){ newStr += "..."; } return newStr; } alert(subString("js截取中英文字符串无乱码",10,true)); </script>
