如何使用以登录弹出结束的jquery创建5秒倒计时器？

Question

如何创建一个jquery计时器,当链接被"鼠标悬停"时启动,显示1,2,3,4和5,一个接一个.然后在5上弹出一个登录框？

干杯.

Answer 1

怎么样:

var counter = 0;
var interval = setInterval(function() {
    counter++;
    // Display 'counter' wherever you want to display it.
    if (counter == 5) {
        // Display a login box
        clearInterval(interval);
    }
}, 1000);

Answer 2

这正是适合我的代码:

<p>You'll be automatically redirected in <span id="count">10</span> seconds...</p>

<script type="text/javascript">

window.onload = function(){

(function(){
  var counter = 10;

  setInterval(function() {
    counter--;
    if (counter >= 0) {
      span = document.getElementById("count");
      span.innerHTML = counter;
    }
    // Display 'counter' wherever you want to display it.
    if (counter === 0) {
    //    alert('this is where it happens');
        clearInterval(counter);
    }

  }, 1000);

})();

}

</script>

<meta http-equiv="refresh" content="10;url=http://www.example.com" />

希望能帮助到你 ;)

JS

function c(){
    var n=$('.c').attr('id');
    var c=n;
    $('.c').text(c);
    setInterval(function(){

        if(c>=0){
            $('.c').text(c);
        }
        if(c==0){
