UI Script to require at least one in a list of checkboxes be checked for form to be submitted

I am working on a donations form and I have a list of check boxes, at least one needs to be checked for the form to be submitted. I'd like a notice to popup on submit if the user did not select at least one checkbox.

I'm thinking a UI script on submit would do the trick but I fall short on how to write the section to check if at least one of the boxes is checked.

I found this in the question: onSubmit client script to prevent form submission

function onSubmit() {

if(g_form.getValue('ad_domain') == 'YES' || g_form.getValue('ad_domain') == 'YESb' && g_form.getValue('question_choice') == 'incorrect_info'){}

  if(g_form.getValue(user_confirm') == 'false' ){ //this is the checkbox

  alert('Please be sure to check the box before submitting a ticket.');

  return false;

}

}

Kinda does the trick but it is looking at specific check boxes to be checked.

Yes.. It should be only one for the selection. Are you configuring only the first checkbox? It is a little tricky but you need to configure only your "Donation" checkbox.

The following script, once modified with you values will do the trick.

function onSubmit(){
   //Set the mandatory checkbox variable names and total mandatory count here
   
   var mandatoryVars = 'agreement,agree_terms'; //checkbox values to check
   var mandatoryCount = 2; //mandatory number of checkboxes
   
   var passed = forceMandatoryCheckboxes(mandatoryVars, mandatoryCount);
   if (!passed){
      //Abort the submit
      alert('You must agree to both of the ' + mandatoryCount + ' disclaimer terms.');
      return false;
   }
}
function forceMandatoryCheckboxes(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]) == 'true'){
            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;
}

Change the two VARS: var mandatoryVars and var mandatoryCount so they reflect your requirements as to the number of checkboxes and list the checkbox values (separated by a ,).

Also you can either modify the alert line or take it out; your choice. The script was something I used for a legal disclaimer checkbox confirmation on a form.

You can try a code like this

 

function onSubmit() {
//Type appropriate comment here, and begin script below
if ((g_form.getValue('request_to') == "Add Access" || (g_form.getValue('request_to') == "Change Access"))){
if (g_form.getValue('dev_access') == "false" && g_form.getValue('qa_access') == "false" && g_form.getValue('access_cmsi') == "false"){
alert("'You cannot continue with the request without selecting at least one option (QA,Dev or CMSIPROD).");
return false;
}
}

}

 

dev_access and qa_access is the checkbox, instead of doing && you can probably do ||
