I have 3 check boxes in my page. FIDDLE 

<form>
    <input type="checkbox" name="vehicle" value="Bike">I have a bike<br>
    <input type="checkbox" name="vehicle" value="Car">I have a car <br>
    <input type="checkbox" name="vehicle" value="Scooter">I have a Scooter <br>
    <input type="submit" value=" Submit ">
</form>

When the user clicks on "Submit", it navigates to another page. When I visit the same page again, I want to see the values which I previously selected. How can I do that using Javascript?

You need to use a cookie (or some other persistent storage) to store the values of whatever is checked.

With a cookie, you can do this by attaching event listeners to the checkboxes, so that when they are updated (selected/deselected) a cookie is stored (or updated) containing their current values.

When the page initially loads, you will then check for the presence of the cookie and populate the boxes accordingly.

Here's one way you might do it. This uses the jQuery cookie library.

<!DOCTYPE HTML>
<html>
  <head>
    <meta charset="utf-8">
    <title>Persist checkboxes</title>
  </head>

  <body>
    <div>
      <label for="checkAll">Check all</label>
      <input type="checkbox" id="checkAll">
    </div>
    <div>
      <label for="option1">Option 1</label>
      <input type="checkbox" id="option1">
    </div>
    <div>
      <label for="option2">Option 2</label>
      <input type="checkbox" id="option2">
    </div>
    <div>
      <label for="option3">Option 3</label>
      <input type="checkbox" id="option3">
    </div>

    <script src="http://ajax.googleapis./ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script src="http://cdn.jsdelivr/jquery.cookie/1.4.0/jquery.cookie.min.js"></script>

    <script>
      $("#checkAll").on("change", function() {
        $(':checkbox').not(this).prop('checked', this.checked);
      });

      $(":checkbox").on("change", function(){
        var checkboxValues = {};
        $(":checkbox").each(function(){
          checkboxValues[this.id] = this.checked;
        });
        $.cookie('checkboxValues', checkboxValues, { expires: 7, path: '/' })
      });

      function repopulateCheckboxes(){
        var checkboxValues = $.cookie('checkboxValues');
        if(checkboxValues){
          Object.keys(checkboxValues).forEach(function(element) {
            var checked = checkboxValues[element];
            $("#" + element).prop('checked', checked);
          });
        }
      }

      $.cookie.json = true;
      repopulateCheckboxes();
    </script>
  </body>
</html>

Save it to cookie using document.cookie as key=value pairs separated by semicolons:

document.cookie = "vehicle=Bike; name=Billy;"

Then look it up when you build the page

If it is within the same browser session you can maintain them in sessions.

OR

Set a cookie to remember the selected value
