js 過濾字符 和檢測 特殊字符【轉】

// var str1 = str.replace(/\[\\'\\"\\\\\\/\\b\\f\\n\\r\\t\]/g, '');// 去掉轉義字符  
// var str2= str.replace(/\[\\-\\\_\\,\\!\\|\\~\\`\\(\\)\\#\\$\\%\\^\\&\\\*\\{\\}\\:\\;\\"\\L\\\\?\]/g, '');// 去掉特殊字符  
// return str2;

var containSpecial = RegExp(/\[(\\ )(\\~)(\\!)(\\@)(\\#)(\\$)(\\%)(\\^)(\\&)(\\\*)(\\()(\\))(\\-)(\\\_)(\\+)(\\=)(\\\[)(\\\])(\\{)(\\})(\\|)(\\\\)(\\;)(\\:)(\\')(\\")(\\,)(\\.)(\\/)(\\)(\\?)(\\)\]+/);  
return ( containSpecial.test(s) ); 判斷是否含有

var filterRule= /\[^0-9a-zA-Z\_\]/g;  
var judge= filterRule.test(str); //判斷傳進來的數據是否含有特殊字符。test函數返回匹配結

var rows=JSON.stringify(rows);////將json對象轉換成json對符串  
var rows=JSON.parse(rows);//將json字符串轉換成json對象
