通过@Alex,@ user824294和这个问题：How Can I create A 5 second Countdown timer with jquery that ends with a login popup?的组合改为这个.现在工作很好,功能倒数很大.多谢你们！

window.onload=function(){ 
    var counter = 5;
    var interval = setInterval(function() {
        counter--;
        $("#seconds").text(counter);
        if (counter == 0) {
            redirect();
            clearInterval(interval);
        }
    },1000);

};

function redirect() {
    document.checkout_paypal.submit();
}
