I have a page with a form that is being used to ask a question. When the submit button is clicked, it does the follow, determines if the user checked the right box, displays the answer and explanation, and disables the checkboxes and submit button to prevent re-answering the question. My issue is that when the user clicks the submit button the answers, and the disabling appear for only a split second before the page reloads. How do I stop this, I want the user to see if they are correct and not be able to change their answers. When I run it in Dreamweaver where I am building the pages, it runs fine in live view.

Code is below:

    return false if there's an error on disablefields() function – slashsharp Apr 16 '15 at 14:03
  • Same as above comment but I am sympathizer of just `return` for cases in which is necessary only to go out of function and not return something. – kosmos Apr 16 '15 at 14:08
  • Have a look at this question: http://stackoverflow.com/questions/1357118/event-preventdefault-vs-return-false – Guinn Apr 16 '15 at 14:11

As of right now your code is not "determining if the user checked the right box, displaying the answer and explanation" as you explained but that is OK and easy to implement after. Here is the answer to your question.

You should replace your id="ex3" button with the anchor tag code provided below (anchor tag is for simplicity but you can use another element to call the function with a click event). Either way, you do not need to submit a form as you are not posting information according to your requested behavior.

<a id="ex3" href="javascript:disablefields()">submit</a>

Update your function with this:

function disablefields() {
        {


                document.getElementById('check1').disabled = 'disabled';
                document.getElementById('check2').disabled = 'disabled';
                document.getElementById('check3').disabled = 'disabled';
                document.getElementById('check4').disabled = 'disabled';
                document.getElementById('ex3').disabled = 'disabled';
                document.getElementById('ex3').innerHTML = 'Answers Submitted';



        }

    }

You will then get the exact behavior requested in your question minus the validation process that you described. It is easy to add that to this solution with a conditional statement or calling a validation function and then if valid calling the disablefields function.

 function formVal() {
            {
     //put all of your validation requirements here and see if 
     var isValid = [check form function here]
    if(isValid){
         disablefields();
    }else {
    //send a message to user to correct fields and do not disable
    }

       <a id="ex3" href="javascript:formVal()">submit</a>

If you do choose to submit the information to the server at some later date simply make an AJAX call sending the form information after your disablefields call.

Fixed it by calling both function from the onClick and changing the type to button. 

 <input type="button" value="Submit" id="ex3" onclick="show_all(); disablefields();"  >
