Answer 1

jQuery. Since it makes the task easy for you. You can put the repeater in a well id-ed div element; also give a good class name for your checkbox and do something like:

$('#chkContainer .chks').each(function(){

    if(this.checked){
        //validation code goes here
    }
});

I’ve only shown you a simple way, the actual path to take is your own creation.

UPDATE:

Well, since you are not using jQuery, try something like:

var divContainer = document.getElementById('chkContainer');
var inputs = divContainer.getElementsByTagName('input');
for(x=0; x<inputs.length; x++){
    var element = inputs[x];
    //check if the element if of type checkbox,
    //and if that checkbox is checked
    if(element.type == 'checkbox' && element.checked){
        //code goes here...
    }
}
