function stripscript(s) {
var pattern = new RegExp("[`~!@#$^&*()=|{}':;',\\[\\].<>/?~！@#￥……&*（）——|{}【】‘；：”“'。，、？]");
var rs = "";
for (var i = 0; i < s.length; i++) {
rs = rs+s.substr(i, 1).replace(pattern, '');
}
return rs;
}

function stripscript(s) {
var pattern = new RegExp("[[\\]/:*?\"<>|]");
var rs = "";
for (var i = 0; i < s.length; i++) {
rs = rs+s.substr(i, 1).replace(pattern, '');
}
return rs;
}

var s = "我是啊啊啊\r\n\r\n\n\n\r";
s = s.replace(/[\r\n]/g, '');
alert(s);
