[WebMethod]
public int checkIshege(int fid)
{
int n = 0;
StringBuilder Str = new StringBuilder();
Str.Append("Update RM_Admin_Work");
Str.Append(" set [Ishege]=@Ishege"); SqlParameter[] parameters ={
new SqlParameter("@Ishege",SqlDbType.Int,4)
}; parameters[0].Value = fid;
RM.DataProvider.SqlDBO db = new SqlDBO();
n = db.execnonsql_ExecuteNonQuery(Str.ToString(), parameters);
return n;
}
js function NotAwards(id) {
alert(id);
$.ajax({
type:"post",
contentType:"text",
url:"/WebService/check.asmx/checkIshege",
data:"{'fid':'" + id + "'}",
success:function() { }
});
}
这个id可以alert的出来，我上面的checkIshege这个方法加了断电，但是 调试的就是跳不同过来怎么回事大侠
将你的 [WebMethod] 方法移到ajax的这个页面，并用state修饰，看下能否调用

然后，JQ调用WebService最后加上Content-Type:application/json;utf-8属性，因为默认的JQ不知道是什么处理方式。然后记得在输出的Success函数里进行数据转换，例如var json = eval('(' + msg + ')');
改成
$.ajax({
type:"post",
contentType:"json",
dataType:"application/json;charset=uft-8"
url:"/WebService/check.asmx/checkIshege",
data:"{'fid':'" + id + "'}",
success:function(reuslit) {
alert(result.d) }
});
一定要加个d。放回值
你这样写 }
改成

data:"{fid:" + id + "}",
success:function(reuslt) {
