Form validation - form.length

[braveheartkenya]

Greetings all! I'm quite new to javascript so i may have some rather silly kind of questions... but anyway here's the problem... I want to loop through all the elements in a form so as to check their values in order to validate the relevant fields, i thought i could get the number of form objects within the form using "formName.length." Then use a loop to go through all the form fields. It seems formName.length is not working for me ... it's returning "undefined" or "0" values. How could i get the number of form objects within a certain form. My code is as follows: [CODE] window.moveTo(100,100); window.resizeTo(300,460); //window.locationbar.visible=false; //window.menubar.visible=false; //window.personalbar.visible=false; //window.scrollbars.visible=false; //window.statusbar.visible=false; //window.toolbar.visible=false; //window.resize=false; //window.resizeable=no; var elementNo; elementNo = document.registrationForm.length; //elementNo = document.registrationForm.txtFirstName.value; var num; num = document.forms[0].length; var counter = 0; var myMessage = "Please ensure that you have filled in the following fields:\n"; var myFieldsAlert = ""; var myAlertFlag="0"; function validate(){ // alert("abc "+elementNo); alert("abc "+num); /**/ while(counter<elementNo){ // if(registrationForm.elements[counter].value==""){ myFieldsAlert += "-"+registrationForm.elements[counter].id+"\n"; myAlertFlag="1"; } if(registrationForm.optGenderM.value!="0" || registrationForm.optGenderF.value!="1"){ myFieldsAlert += "-Gender\n"; myAlertFlag="1"; } counter++; } /**/ /**/ if(myAlertFlag=="1"){ alert(myMessaage+myFieldsAlert); } else{ registrationForm.submit(); } myAlertFlag ="0"; /**/ return false; } [/CODE] Could someone please enlighten me on the issue at hand and propose a solution. (By the way the code is in a HTML page which is called up as a popup). Any help would be greatly appreciated...
