We can read the user selected checkbox values from a set of Checkboxes having common name and display the same in an alert window.

We will display a set of checkboxes for user to select. On submit or click of a button the onClick event of the button will execute one JavaScript function validate() and pass the data to it. The length property of the name of checkboxes will tell us how many checkboxes are there.
We can read the value of each selected checkbox by using checked property.
By using one if condition we can read the value of all the checkboxes for which the checked property is true ( the checkbox is checked by the user )
After looping through all checkboxes we will check the value of the string variable and if it is blank then we will give the message to the user to check the any checkbox, otherwise we will display the value of the string. This string variable will content all values of the selected checkboxes.
