How to Check if a Checkbox is Checked or not Using jQuery

Last Modified: January 4, 2021 | by Editorial Staff

You can use jQuery to check if a checkbox is checked. You can either use the prop() method in jQuery 1.7 or the attr() method in lower versions. We will also show you how to use the :checked selector to achieve the same result.

jQuery 1.7+

$(document).ready(function(){
   $('input[type="checkbox"]').click(function(){
     if($(this).prop("checked") == true){
        console.log("Checkbox is checked.");
     }
     else if($(this).prop("checked") == false){
        console.log("Checkbox is unchecked.");
     }
   });
});

Lower than jQuery 1.7

$(document).ready(function(){
   $('input[type="checkbox"]').click(function(){
      if($(this).attr("checked") == true){
         console.log("Checkbox is checked.");
      }
      else if($(this).attr("checked") == false){
         console.log("Checkbox is unchecked.");
      }
  });
});

You can also use the jQuery :checked selector to check if the checkbox is checked using the following example.

$(document).ready(function(){
  $('input[type="checkbox"]').click(function(){
     if($(this).is(":checked")){
       console.log("Checkbox is checked.");
     }
     else if($(this).is(":not(:checked)")){
          console.log("Checkbox is unchecked.");
     }
   });
});
