Jquery内的加载条在100％后继续移动

标签： jquery

我试图在第4页开始加载栏，但它仍然超出100％的布局。如果我在第1页上取消了条形加载功能，它可以正常工作。也许我需要以某种方式关闭该动画功能？

答案 0 :(得分：2)

由于$(".button")的匹配次数超过1次，因此传递给$('.button').hide();的回调会多次运行，因此会将栏扩展到100%以外

只需移动代码以在回调之外扩展进度条就可以解决问题：

＆＃13;
＆＃13; 
$('#cnt2, #cnt3, #cnt4, #cnt5').hide();
$('.button').click(function() {
  //code
  var curr = $(".question:visible");
  var next = curr.next(".question");
  next.delay(300).fadeIn(300);
  curr.fadeOut(300);
  if (!next.next(".question").length) {
    //Begin Bar Transition
    $('.button').hide();
    $("#bar").width(0);
    $("#bar").delay(500).animate({
      width: '+=50%'
    }, 'slow').delay(600).animate({
      width: '+=20%'
    }, 'slow').delay(60).animate({
      width: '+=10%'
    }).delay(2000).animate({
      width: '+=20%'
    }, 'slow');
  }
});
