客户端验证不起作用？ [英] client side validation not working?

问题描述

var amntrec1 = document.getElementById('<%=txtAmountRec.ClientID%>');
         if(amntrec1.value > 0) {
             var recdate = document.getElementById('<%=txtrecdate.ClientID%>');
             if (recdate.value == "") {
                 alert("Must Enter Received date");
                 return false;
             }
             return false;
         }

是否正确？如果我编写此代码，验证后不是解雇？

is it correct ?if i write this code,after validation is not fired?

推荐答案

function valid()
{
var amntrec1 = document.getElementById(TextboxID);
         if(amntrec1.value  0) {
             var recdate = document.getElementById(TextboxID);
             if (recdate.value == "") {
                 alert("Must Enter Received date");
                 return false;
             }
             return false;
         }


}
//call from Button
 <asp:Button ID="btn_Login" runat="server" Text="Login"

        onclick="btn_Login_Click"  OnClientClick="return valid();" />
