Because it already has a value, it's not straight forward. But can it be added to this code to make it work?
It's a simple "I have read the terms" type form.
Code: Select all
function formCheck(formobj){
// Enter name of mandatory fields
var fieldRequired = Array("firstname", "lastname", "telephone", "email", "address1", "town", "postcode", "terms");
// Enter field description to appear in the dialog box
var fieldDescription = Array("Firstname","Lastname","Telephone Number","Email Address","Address","Town","Postcode", "Terms and Conditions");
// dialog message
var alertMsg = "Please complete these fields to complete your registration:\n";
var l_Msg = alertMsg.length;
for (var i = 0; i < fieldRequired.length; i++){
var obj = formobj.elements[fieldRequired[i]];
if (obj){
switch(obj.type){
case "select-one":
if (obj.selectedIndex == -1 || obj.options[obj.selectedIndex].text == ""){
alertMsg += " - " + fieldDescription[i] + "\n";
}
break;
case "select-multiple":
if (obj.selectedIndex == -1){
alertMsg += " - " + fieldDescription[i] + "\n";
}
break;
case "text":
case "textarea":
if (obj.value == "" || obj.value == null){
alertMsg += " - " + fieldDescription[i] + "\n";
}
break;
default:
}
if (obj.type == undefined){
var blnchecked = false;
for (var j = 0; j < obj.length; j++){
if (obj[j].checked){
blnchecked = true;
}
}
if (!blnchecked){
alertMsg += " - " + fieldDescription[i] + "\n";
}
}
}
}
if (alertMsg.length == l_Msg){
return true;
}else{
alert(alertMsg);
return false;
}
}
