$("html").die().live("keydown",function(event){
if(event.keyCode==13){
//这里添加要处理的逻辑
}
});

//绑定回车动作
$('textarea[name=chattext]').keydown(function(event){
if(event.which==13){

}
});

$('input[type="checkbox"][name="types"]:checked').each(function() {
types = types+$(this).val()+ "|";
}
);

$.ajax({
url : "${pageContext.request.contextPath}/UOSRoleManangerAction.do?method=createRole",
type : "post",
dataType : "html",
data:{"roleName":roleName,"roleDescription":roleDescription,"roles":roles,"types":types},
success : function(data){
var dataObj=eval("("+data+")");
if(dataObj.result){
alert("操作成功！");
submitForm(null,"initPage");
}else {
alert("操作失败！");
}
}
});
