Question

    $(function(){
        $(".test").each(function(){
            test();
        });
    });

     function test(){
        $(this).css("border","1px solid red").append(" checked");
    }

why is this not working? what am I missing?
this is my test html:

    <p>test</p>
    <p>test</p>
    <p class="test">test</p>
    <p>test</p>

The $(this) cannot be used in that way, because you don’t specify the context of the test() function:

$(".test").each(function(){
        test($(this));
});

function test(el){
     el.css("border","1px solid red").append(" checked");
}

or

$(".test").each(function(){
      test.call(this);
});
function test(){
   $(this).css("border","1px solid red").append(" checked");
}
