Checkbox validation

55
Dear Bytes Team

How would you use JavaScript function validation to check wether or not a checkbox is checked or not?

I am able to check input fields, however I am not sure about checkboxes.

Regards

It it simple, Just have a id attribute in the checkbox. And then use the DOM object for checking.

ex:
HTML
Expand|Select|Wrap|Line Numbers
  1. <input type="checkbox" id="testObj" checked="checked"/>
JS
Expand|Select|Wrap|Line Numbers
  1. if(document.getElementById('testObj').checked==true)
  2.   alert("Check box checked");
  3. else
  4.   alert("Check box Not checked");
  5.  
  6.  
Thanks and Regards
