Switch the background color of the checkbox div or label with a single click

Question

Switch the background color of the checkbox div or label with a single click

I have successfully implemented the following code, with one small issue. When I select the checkbox, the background color of the div changes from #fff to #ffe600 as expected. However, after submitting the form and refreshing the page, the background color reverts back to #fff. Is there a way to ensure that the background color remains #ffe600 even after the page is refreshed post form submission? While the checkbox stays checked after the page refresh, the div background color resets to #fff. Any insights on how to maintain the div background color as #ffe600 upon page refresh would be greatly appreciated. This issue has left me puzzled.

function myFunction(x, _this) {
  if (_this.checked) {
    x.style.backgroundColor = '#ffe600';
  } else  {
    x.style.backgroundColor = '#fff';
  }
}

#product1 {
  background-color: #fff;
  padding: 3px 5px 3px 7px;
  margin-top: 6px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="product1">
  <label class="chk">
    <input type="checkbox" onChange="myFunction(product1, this)" name="select_product" value="Y" />Label goes here.</label>
</div>

Thanks!

To highlight the currently checked boxes, you can use jQuery to check on load and apply the desired styling.

$('input[type=checkbox]').each(function(){
  if($(this).is(':checked'))
$(this).parent().parent().css('backgroundColor','#ffe600');
  else
$(this).parent().parent().css('backgroundColor','#fff');
});
function updateColor(x, _this) {
  if (_this.checked) {
    x.style.backgroundColor = '#ffe600';
  } else  {
    x.style.backgroundColor = '#fff';
  }
}

#product1 {
  background-color: #fff;
  padding: 3px 5px 3px 7px;
  margin-top: 6px;
}
#product2 {
  background-color: #fff;
  padding: 3px 5px 3px 7px;
  margin-top: 6px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="product1">
  <label class="chk">
    <input type="checkbox" onChange="updateColor(product1, this)" name="select_product" value="Y" />Label goes here.</label>
</div>
<div id="product2">
<label class="chk">
<input checked type="checkbox" onChange="updateColor(product2, this)" name="select_product2" value="V" />Label goes here 2.</label>
</div>

Do you really need to refresh the page every time? It seems like AJAX is already being used.

Have you implemented a function to handle form submission? If so, you can prevent the page from refreshing by following these steps:

<form onsubmit="submitHandler(event)">
      // form elements
</form>

Here's a JavaScript example of how to achieve this:

function submitHandler(event) {
    event.preventDefault();
    // process form data
}

By using event.preventDefault(), you can prevent the page from reloading and maintain the background color of your element.

To save and retrieve the checkbox state, you can utilize either localstorage or Cookie. Upon page load, you can access the stored state from these methods. Alternatively, you can implement a check similar to myFunction when the page loads, like so:

window.onload = function(){
 var checkBoxElement = document.querySelector("div#product1 input[type='checkbox']");

 var productElement = document.getElementById("product1"); 
 if (checkBoxElement.checked) {
    productElement.style.backgroundColor = '#ffe600';
  } else  {
    productElement.style.backgroundColor = '#fff';  
}
