Help with a For Loop

[fabwebdesigns]

I have a questionnaire form with 12 text fields on it. The field names are Question_1, Question_2, Question_3, ... Question_12

I need to verify the fields are not empty.

Here's the script I've written but IE says undefined index:

var i;
for (i=1; i<13; i++){
if (form2.Question_i.value.length==""){
errors += '- Question ' + i + ' is required.\n';
}
}

if (errors) {

alert('The following error(s) occurred:\n'+errors );

}
else{
document.MM_returnValue = (errors == '');
}


#2
I've tried the following version and it didn't not worked either.
var i;
for (i=1; i<13; i++){
if (form2.Question_[i].value.length==""){
errors += '- Question ' + i + ' is required.\n';
}
}

#3

var i;
for (i=1; i<13; i++){
if (form2.Question_(i).value.length==""){
errors += '- Question ' + i + ' is required.\n';
}
}

if (form2.Question_+ i +.value.length==""){
errors += '- Question ' + i + ' is required.\n';
}
}



what am i doing wrong?

Could you up the rest of the codes :)

function MM_validateForm2() {
var errors;

errors='';

if (form2.Name.value.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Name is required.\n';
}

if (form2.Home_Phone.value.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Home Phone number is required.\n';
}
if (form2.Work_Phone.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Work Phone number is required.\n';
}
if (form2.Mobile_Phone.value.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Mobile Phone number is required.\n';
}
if (form2.Email_Address.value.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Email Address is required.\n';
}
if (form2.Last_Year_Annual_Income.value.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Last Year\'s Annual Income is required.\n';
}
if (form2.Licenses_Degree.value.length==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your License(s)\\Degree(s) are required.\n';
}

var i;
for (i=1; i<13; i++){
if (form2.Question_i.value.length==""){
errors += '- Question ' + i + ' is required.\n';
}
}




if (errors) {

alert('The following error(s) occurred:\n'+errors );
document.MM_returnValue = (errors == '');

}
else{
document.MM_returnValue = (errors == '');
}

}

Up the markups (HTML) :)

Quick side note:..Place your codes inside the [code] [/code ] tag of the forum ;)

Better still, instead of clogging up the forum with tons of code:

Please post a link to the page on your site that contains the problematic code so we can check it out.

Well, from what I see is that your using length to get the length, but the length wouldn't equal empty space. It needs to have a value, so it'd be 0. So I'm not the best at JS, but I'm guessing that this'll work:


function MM_validateForm2() {
var errors;

errors='';

if (form2.Name.value.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Name is required.\n';
}

if (form2.Home_Phone.value.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Home Phone number is required.\n';
}
if (form2.Work_Phone.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Work Phone number is required.\n';
}
if (form2.Mobile_Phone.value.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Mobile Phone number is required.\n';
}
if (form2.Email_Address.value.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Email Address is required.\n';
}
if (form2.Last_Year_Annual_Income.value.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Last Year\'s Annual Income is required.\n';
}
if (form2.Licenses_Degree.value.length=="0"){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your License(s)\\Degree(s) are required.\n';
}

var i;
for (i=1; i<13; i++){
if (form2.Question_i.value.length=="0"){
errors += '- Question ' + i + ' is required.\n';
}
}




if (errors) {

alert('The following error(s) occurred:\n'+errors );
document.MM_returnValue = (errors == '');

}
else{
document.MM_returnValue = (errors == '');
}

}

Thats just a guess, and if that doesn't work:


function MM_validateForm2() {
var errors;

errors='';

if (form2.Name.value==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Name is required.\n';
}

if (form2.Home_Phone.value==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Home Phone number is required.\n';
}
if (form2.Work_Phone==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Work Phone number is required.\n';
}
if (form2.Mobile_Phone.value==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Mobile Phone number is required.\n';
}
if (form2.Email_Address.value==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your Email Address is required.\n';
}
if (form2.Last_Year_Annual_Income.value==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Last Year\'s Annual Income is required.\n';
}
if (form2.Licenses_Degree.value==""){
//alert("here" + form2.Q13.options[form2.Q13.selectedIndex].value);
errors += '- Your License(s)\\Degree(s) are required.\n';
}

var i;
for (i=1; i<13; i++){
if (form2.Question_i.value==""){
errors += '- Question ' + i + ' is required.\n';
}
}




if (errors) {

alert('The following error(s) occurred:\n'+errors );
document.MM_returnValue = (errors == '');

}
else{
document.MM_returnValue = (errors == '');
}

}
