How do you validate multiple check box in java script?

Answer 1

You can use this logic or a logic similar :

For Example:

function validate()

{

var arrayOfcheckBoxes = document.getElementsByName('checkBoxes[]');

var selectedBoxes = 0;

for (var i = 0; i < arrayOfcheckBoxes.length; i++)

{

if (arrayOfcheckBoxes[i].checked)

{

selectedBoxes ++;

}

}
