Question from the jQuery test

$(":checkbox").click( function(){
   $(":checkbox").not(this).attr("checked", false);
   $(this).attr("checked", true);
});

We previously place in html on each of the checkbox type input tags of the first list a name="liste1" attribute and an on click="set_click(index)" attribute with an id= attribute"lid(index)"(the choice of names is arbitrary).

Then apply the following code:

function set_click(index){
    $("input[name=list1]").each(
        function(){$(this).attr("checked", false);}
    );
    $("#lid[index]").attr("checked", true);
}

Another method.
