冷知识 javascript 对特殊符号的转义顺序

            //反斜杠转移写在最前面，这样就不会影响后面的转换
            searchSegment = searchSegment.replace(////g, "////"); 
            searchSegment = searchSegment.replace(//+/g, "//+").replace(//-/g, "//-").replace(//?/g, "//?").replace(//*/g, "//*").replace(//./g, "//.");
            searchSegment = searchSegment.replace(/{/g, "//{").replace(/}/g, "//}").replace(//(/g, "//(").replace(//)/g, "//)").replace(//[/g, "//[").replace(//]/g, "//]");
            searchSegment = searchSegment.replace(//$/g, "//$").replace(//^/g, "//^").replace(////g, "//").replace(//|/g, "//|");
