to check whether a checkbox is checked or not in javascript, you can use the `checked` property of the checkbox element. the `checked` property returns `true` if the checkbox is checked, and `false` if it is not checked.
here is a step-by-step tutorial along with a code example to demonstrate how to check if a checkbox is checked in javascript:
step 1: create an html file
create an html file (e.g., `index.html`) and add the following code to create a checkbox element:
step 2: add javascript code
add the following javascript code to check if the checkbox is checked:
in the above code:
we first get a reference to the checkbox element with the id `mycheckbox`.
we also get a reference to a `p` element with the id `result` where we will display the result.
inside the `checkcheckbox` function, we check the `checked` property of the checkbox element and update the text content of the `resultelement` accordingly.
step 3: test the code
open the html file in a web browser, check or uncheck the checkbox, and then click the "check" button to see the result displayed on the page.
example output:
if the checkbox is checked and you click the "check" button, you will see: "checkbox is checked."
if the checkbox is not checked and you click the "check" button, you will see: "checkbox is not checked."
that's it! you have successfully implemented a javascript function to check if a checkbox is checked or not.
