MRVS How to iterate and check each row if a variable value is not empty

[Ljone]

Hi,

I have an Onsubmit client script that should check if for each rows, 1 variable: 'member_replacement' is not empty and all rows are filled in. How to achieve this? 

We are auto-populating the addtion of row  and users need to update each row variable:member_replacement

below is my current script but not working .  Thank you.

function onSubmit() {
//Type appropriate comment here, and begin script below

var multiRowVariableSet = JSON.parse(g_form.getValue('group_creation_members')); //internal name mrvs
var numberOfRows = multiRowVariableSet.length;

for (var i = 0; i < multiRowVariableSet.length; i++) {
alert(numberOfRows);

if(multiRowVariableSet[i].member_replacement == ""){                //variable name
alert("With Value "+ multiRowVariableSet.member_replacement + " " + multiRowVariableSet.group_member_name);
}
else{
alert("Without Value "+ multiRowVariableSet.member_replacement + " " + multiRowVariableSet.group_member_name);

}
}

 }

@Ljone 

So you want to check if both the variables are non-empty

if any row has both the variables as empty then stop form submission

update as below

function onSubmit() {
//Type appropriate comment here, and begin script below


var mrv = JSON.parse(g_form.getValue('group_creation_members')); // mrvs internal name
if (mrv.length >= 1){
alert(mrv);

var memberArrCount = 0;
var replacingArrCount = 0;

for (var i=0; i<mrv.length; i++){

if(mrv[i].member_replacement != '')
memberArrCount++;

if(mrv[i].group_member_who_are_you_replacing != '')
replacingArrCount++;

}

if(mrv.length != memberArrCount && mrv.length != replacingArrCount){
alert('empty column');
return false;
}
}

}

Hi Ankur, thank u for your reply, apologies, i updated the question just now as i just received a change in requirement, i just need 1 variable checking 'member_replacement' need to iterate in each row to check if this is already populated, below is the script i created but not evaluating correctly can u check below?

function onSubmit() {
//Type appropriate comment here, and begin script below

var multiRowVariableSet = JSON.parse(g_form.getValue('group_creation_members')); //internal name mrvs
var numberOfRows = multiRowVariableSet.length;

for (var i = 0; i < multiRowVariableSet.length; i++) {
alert(numberOfRows);

if(multiRowVariableSet[i].member_replacement == ""){                //variable name
alert("With Value "+ multiRowVariableSet.member_replacement + " " + multiRowVariableSet.group_member_name);
}
else{
alert("Without Value "+ multiRowVariableSet.member_replacement + " " + multiRowVariableSet.group_member_name);

}
}

Hi Ankur,

I am able to modify your code to below and it works 🙂 thanks for the help!

function onSubmit() {
//Type appropriate comment here, and begin script below
var mrv = JSON.parse(g_form.getValue('group_creation_members')); // mrvs internal name
if (mrv.length >= 1){
//alert(mrv.length);

var memberArrCount = 0;

for (var i=0; i<mrv.length; i++){
if((mrv[i].member_replacement == 'yes') ||(mrv[i].member_replacement == 'no')) //yes-no field
memberArrCount++;
//alert(mrv + " " +memberArrCount );
}

if (mrv.length != memberArrCount){
return false;
}
else{
return true;
}

}}
