Javascript validation for required fields

Rajiya

Hi, I am having a login form. I am validating if the userid id and password is blank and returing a boolean value in javascript. If userid is not specified then i am giving an alert and setting the focus back to txtUserid textbox. but it throws a javascript error saying document.frmLogin.txtuserid is null or not an object. Am sending the code.Plz check where i am going wrong. function fValidate() { if (document.frmLogin.txtUserid.value == "" && document.frmLogin.txtPassword.value != "") { alert("User Id must be specified !"); //document.frmLogin.txtUserId.focus(); return false; } else if (document.frmLogin.txtUserid.value != "" && document.frmLogin.txtPassword.value == "") { alert("Password must be specified !"); document.frmLogin.txtPassword.value = "" document.frmLogin.txtPassword.focus(); return false; } else if (document.frmLogin.txtUserid.value == "" && document.frmLogin.txtPassword.value == "") { alert("User Id and Password must be specified !"); //document.frmLogin.txtUserId.focus(); document.frmLogin.txtPassword.focus(); return false; } else return true; } Thanks, Riz

Apparently, document.frmLogin.txtUserid doesn't work. Is this ASP.NET ? I assume so. If so, you need to write your client side user Ids into a var and then use those and document.getElementByID to find the controls you want. Your server side control names are not passed through to the client side, check out the source of yuor page and you will see.

Why don;'t you use Required field validator instead of having bulk of javascirpt code
