Client script to make 1 of 3 fields mandatory if a checkbox is selected

[MonicaW]

I'm using a client script as follows and can't seem to get it working.  When a checkbox is selected, I want the OnSubmit script to require one of three fields.  When the checkbox is not selected, it throws a browser error onSubmit.  If checkbox is selected, doesn't seem to function either.  Here's what I have:

function onSubmit() {

if (g_form.getValue('personal_information') == 'true')

var mandatoryVars = 'field1,field1,field3';

var mandatoryCount = 1;

var passed = forceMandatoryFields(mandatoryVars, mandatoryCount);

if (!passed) {

//Abort the submit

alert('You must select at least ' + mandatoryCount + ' client information field.');

return false;

}

}

function forceMandatoryFields(mandatory, count) {

//Split the mandatory variable names into an array

mandatory = mandatory.split(',');

var answer = false;

var varFound = false;

var numTrue = 0;

//Check each variable in the array

for (x = 0; x < mandatory.length; x++) {

//Check to see if variable exists

if (g_form.getControl(mandatory[x])) {

varFound = true;

//Check to see if variable is set to 'true'

if (!(g_form.getValue(mandatory[x]))) {

numTrue++;

//Exit the loop if we have reached required number of 'true'

if (numTrue >= count) {

answer = true;

break;

}

}

}

}

//If we didn't find any of the variables allow the submit

if (varFound == false) {

answer = true;

}

//Return true or false

return answer;

}

I was able to get this to work using a much more simplified client script:

function onSubmit() {

if(g_form.getValue('client_information') == 'true'){

if((g_form.getValue('field1')=='') && (g_form.getValue('field2')=='') && g_form.getValue('field3')==''){

alert('You must fill out at least one patient information field.');

return false;

}else{

return true;

}

}else{

return true;

}

}

Hi @MonicaW ,

Here is revised code.

function onSubmit() {
    // Check if the checkbox is selected
    if (g_form.getValue('personal_information') == 'true') {
        var mandatoryVars = 'field1,field2,field3';  // Specify the fields to be checked
        var mandatoryCount = 1;  // Set the count for required fields
    } else {
        var mandatoryVars = '';  // No mandatory fields if checkbox isn't selected
        var mandatoryCount = 0;
    }

    // Call the function to check the mandatory fields
    var passed = forceMandatoryFields(mandatoryVars, mandatoryCount);

    if (!passed) {
        // Abort the submit and show an error message
        alert('You must select at least ' + mandatoryCount + ' client information field(s).');
        return false;
    }
}

function forceMandatoryFields(mandatory, count) {
    // If no mandatory fields, return true (nothing to check)
    if (count === 0) {
        return true;
    }

    // Split the mandatory variable names into an array
    mandatory = mandatory.split(',');
    var answer = false;
    var varFound = false;
    var numTrue = 0;

    // Check each variable in the array
    for (var x = 0; x < mandatory.length; x++) {
        // Check if the variable exists
        if (g_form.getControl(mandatory[x])) {
            varFound = true;

            // Check if the variable is not filled out (i.e., it's empty)
            if (!g_form.getValue(mandatory[x])) {
                numTrue++;
                // Exit the loop if we've reached the required number of fields
                if (numTrue >= count) {
                    answer = true;
                    break;
                }
            }
        }
    }

    // If no variables are found, allow the submit
    if (!varFound) {
        answer = true;
    }

    // Return whether the mandatory fields are passed or not
    return answer;
}

@MonicaW 

try this simplified version

function onSubmit() {

    var value1 = g_form.getValue('variable_1');
    var value2 = g_form.getValue('variable_2');
    var value3 = g_form.getValue('variable_3');
    var value4 = g_form.getValue('variable_4');

    if (g_form.getValue('personal_information') == 'true') {
        if (!value1 && !value2 && !value3 && !value3) {
            g_form.addErrorMessage("You must select at least 1 client information field.");
            return false;
        }
    }
    return true;

}
