                                var txtGMarksObtain =  parseInt(document.getElementById("<%=txtGMarksObtain.ClientID%>").value);
                                var txtGMaxMarks = parseInt(document.getElementById("<%=txtGMaxMarks.ClientID%>").value);

                                if (txtGMarksObtain > txtGMaxMarks) {
                                    alert("Graduation Obatined Marks must be less than Max Marks..");
                                    txtGMarksObtain.focus();
                                    return false;
                                }

                                return true;

                            }

 <asp:TextBox ID="txtGMarksObtain" onkeypress="return Gmarks()" runat="server" MaxLength="4"  />

推荐答案

我检查了你的代码，

你能不能如果条件是上面的警告检查：

I have checked your code,
can you check with alert above if condition :

"alert("txtGMarksObtain" + txtGMarksObtain + " and " + "txtGMaxMarks" + txtGMaxMarks);"

你得到的价值与否，我认为代码工作正常，但只是检查控制台你得到任何错误。

you got the value or not, i think code is working fine but just check in console you got the any error.
