There were multiple errors in this code. I also changed a bit to make it simpler.




  1. You have to use .indexOf() not .indexOF(). That's probably
    what's throwing your code off.

  2. For document.querySelectorAll, you only need input:checked


  3. .querySelectorAll returns a NodeList which is more like an object than an array. Therefore, .indexOf() does not work on it. You must loop through it to find the value.

  4. I set the default value of answer to "no", and if it finds photo or name, it will set the value to "yes".


The snippet below works for you. 






function admissible() {

  var b = 4;

  var answer = 'no';

  var elementsList = document.querySelectorAll("input:checked");



  //get the selected checkbox values for the missing elements

  if (elementsList.length >= 0) { //Code works only if some checkbox is checked

  

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

    if (elementsList[i].value == "photo" || elementsList[i].value == "name") {

      answer = "yes";

    }

  }

  

  } else {

    //display error: you must select a value

  }

  console.log(answer);

}

There are a lot of errors in your posted code. The code in the example below fixes them. The comments explain how it is solved.



Small summary:



Query selector



"#question5" + " input:checked"


That query selector was wrong. The checked part will select inputs that have been checked, but your node list will not contain any entries. Combining it into 



"#question5 > div:first-child > input:checked"


will tell document.querySelectorAll to select all elements of type input that are checked within the first div child element of the element with id question5.



Iterating over a node list



Since document.querySelectorAll returns a nodelist (array like) which is not actually an array. In your code you used length check to <= 0. This will always execute the if. Drop the =. Now the if only fires when the nodelist has at least one entry.



Then we cast the nodeList to an array using Array.from and loop over it with Array.prototype.some. Which iterates over every element and if one condition matches it will return true.



We use String.prototype.search instead of String.prototype.indexOf since we can use a regexp to look for the value name|photo in one go. The | (pipe) tells the code to either look for name or photo. If the result is not -1 we found the value.



Working example






function admissible(method) {

  var b = 4;

  var answer = '';

  var elementsList = document.querySelectorAll("#question5 > div:first-child > input:checked"); //fixed the query selector



  //get the selected checkbox values for the missing elements

  if (elementsList.length > 0) { //Code works only if some checkbox is checked

    //cast the node list to array and use array.some to iterate over entries. If one value is found answerFilter will be true.  



    if (method == "some") {

      var answerFilter = Array.from(elementsList).some(function(element) {

        return element.value.search(/name|photo/i) != -1; //check with regexp if value contains photo or name

      });

    }

    else

    {

    

      //map returns an array and lets us return a value we want.

      var answerFilter = Array.from(elementsList).map(function(element) {

        return element.value;

      });

      //now use indexOf like in the original code

      if (answerFilter.indexOf("name") > -1 || answerFilter.indexOf("photo") > -1)

      {

        answerFilter = true;

      }

      else

      {

        answerFilter = false;

      }

    }

    answerFilter ? answer = "yes" : answer = "no"; //use shorthand if/else



  } else {

    //display error: you must select a value

  }

  console.log(answer);

    I think this code is a more generous way to check if an input is checked and retrieve its value. Is more of pseudo code but you can continue from here:



    var inputList = document.querySelectorAll(".input5");
    

    
for (var i = 0; i < inputList.length; i++) {
    
    if (inputList[i].checked) {
    
        if (/^(photo|name)$/.test(inputList[i].value)) {
    
            // your code here
    
        }
    
    }
    
}

      There were multiple errors in this code. I also changed a bit to make it simpler.




      1. You have to use .indexOf() not .indexOF(). That's probably
        what's throwing your code off.

      2. For document.querySelectorAll, you only need input:checked


      3. .querySelectorAll returns a NodeList which is more like an object than an array. Therefore, .indexOf() does not work on it. You must loop through it to find the value.

      4. I set the default value of answer to "no", and if it finds photo or name, it will set the value to "yes".


      The snippet below works for you. 






      function admissible() {
      
  var b = 4;
      
  var answer = 'no';
      
  var elementsList = document.querySelectorAll("input:checked");
      

      
  //get the selected checkbox values for the missing elements
      
  if (elementsList.length >= 0) { //Code works only if some checkbox is checked
      
  
      
  for (var i = 0; i < elementsList.length; i++) {
      
    if (elementsList[i].value == "photo" || elementsList[i].value == "name") {
      
      answer = "yes";
      
    }
      
  }
      
  
      
  } else {
      
    //display error: you must select a value
      
  }
      
  console.log(answer);
      
}

    <input class="input5" type="checkbox" id="elementPhoto" name="element" value="photo"><label for="elementPhoto"><p class="radioChoice">Photo</p></label>

      There are a lot of errors in your posted code. The code in the example below fixes them. The comments explain how it is solved.



      Small summary:



      Query selector



      "#question5" + " input:checked"


      That query selector was wrong. The checked part will select inputs that have been checked, but your node list will not contain any entries. Combining it into 



      "#question5 > div:first-child > input:checked"


      will tell document.querySelectorAll to select all elements of type input that are checked within the first div child element of the element with id question5.



      Iterating over a node list



      Since document.querySelectorAll returns a nodelist (array like) which is not actually an array. In your code you used length check to <= 0. This will always execute the if. Drop the =. Now the if only fires when the nodelist has at least one entry.



      Then we cast the nodeList to an array using Array.from and loop over it with Array.prototype.some. Which iterates over every element and if one condition matches it will return true.



      We use String.prototype.search instead of String.prototype.indexOf since we can use a regexp to look for the value name|photo in one go. The | (pipe) tells the code to either look for name or photo. If the result is not -1 we found the value.



      Working example






      function admissible(method) {
      
  var b = 4;
      
  var answer = '';
      
  var elementsList = document.querySelectorAll("#question5 > div:first-child > input:checked"); //fixed the query selector
      

      
  //get the selected checkbox values for the missing elements
      
  if (elementsList.length > 0) { //Code works only if some checkbox is checked
      
    //cast the node list to array and use array.some to iterate over entries. If one value is found answerFilter will be true.  
      

      
    if (method == "some") {
      
      var answerFilter = Array.from(elementsList).some(function(element) {
      
        return element.value.search(/name|photo/i) != -1; //check with regexp if value contains photo or name
      
      });
      
    }
      
    else
      
    {
      
    
      
      //map returns an array and lets us return a value we want.
      
      var answerFilter = Array.from(elementsList).map(function(element) {
      
        return element.value;
      
      });
      
      //now use indexOf like in the original code
      
      if (answerFilter.indexOf("name") > -1 || answerFilter.indexOf("photo") > -1)
      
      {
      
        answerFilter = true;
      
      }
      
      else
      
      {
      
        answerFilter = false;
      
      }
      
    }
      
    answerFilter ? answer = "yes" : answer = "no"; //use shorthand if/else
      

      
  } else {

        There are a lot of errors in your posted code. The code in the example below fixes them. The comments explain how it is solved.



        Small summary:



        Query selector



        "#question5" + " input:checked"


        That query selector was wrong. The checked part will select inputs that have been checked, but your node list will not contain any entries. Combining it into 



        "#question5 > div:first-child > input:checked"


        will tell document.querySelectorAll to select all elements of type input that are checked within the first div child element of the element with id question5.



        Iterating over a node list



        Since document.querySelectorAll returns a nodelist (array like) which is not actually an array. In your code you used length check to <= 0. This will always execute the if. Drop the =. Now the if only fires when the nodelist has at least one entry.



        Then we cast the nodeList to an array using Array.from and loop over it with Array.prototype.some. Which iterates over every element and if one condition matches it will return true.



        We use String.prototype.search instead of String.prototype.indexOf since we can use a regexp to look for the value name|photo in one go. The | (pipe) tells the code to either look for name or photo. If the result is not -1 we found the value.



        Working example






        function admissible(method) {
        
  var b = 4;
        
  var answer = '';
        
  var elementsList = document.querySelectorAll("#question5 > div:first-child > input:checked"); //fixed the query selector
        

        
  //get the selected checkbox values for the missing elements
        
  if (elementsList.length > 0) { //Code works only if some checkbox is checked
        
    //cast the node list to array and use array.some to iterate over entries. If one value is found answerFilter will be true.  
        

        
    if (method == "some") {
        
      var answerFilter = Array.from(elementsList).some(function(element) {
        
        return element.value.search(/name|photo/i) != -1; //check with regexp if value contains photo or name
        
      });

              you got the complete list of the checkboxes you need to iterate through it to find if any of the checkboxes you are looking for is selected.

              I think this code is a more generous way to check if an input is checked and retrieve its value. Is more of pseudo code but you can continue from here:



              var inputList = document.querySelectorAll(".input5");
              

              
for (var i = 0; i < inputList.length; i++) {
              
    if (inputList[i].checked) {
              
        if (/^(photo|name)$/.test(inputList[i].value)) {
              
            // your code here
              
        }
              
    }
              
}
