Question

我的代码有问题。我正在尝试为滑块创建一个无限循环，并在悬停时暂时停止。我必须要如何得到这个。

function SlideLeft() {
  marginleft = $(".slideinner-style").css("left");
  marginleft = marginleft.replace("px");
  currentindex = $("#currentindex").val();

  if (currentindex == 1)
    return;

  $(".sliderightinner-style").show();

  if (parseInt(currentindex) - 1 == 1)
    $(".slideleftinner-style").hide();

  $("#currentindex").val(parseInt(currentindex) - 1);

  holderwidth = $(".slideinnerholder-style").css("width");
  holderwidth = holderwidth.replace("px");

  $(".slideinner-style").animate({
    "left": (parseInt(marginleft) + parseInt(holderwidth)) + "px"
  }, "slow");
}


function SlideRight() {
  marginleft = $(".slideinner-style").css("left");
  marginleft = marginleft.replace("px");
  holderwidth = $(".slideinnerholder-style").css("width");
  holderwidth = holderwidth.replace("px");
  currentindex = $("#currentindex").val();
  blockcount = $("#blockcount").val();

  if (currentindex == blockcount)
    return;

  $(".slideleftinner-style").show();

  if (parseInt(currentindex) + 1 == blockcount)
    $(".sliderightinner-style").hide();

  $("#currentindex").val(parseInt(currentindex) + 1);

  $(".slideinner-style").animate({
    "left": (parseInt(marginleft) - parseInt(holderwidth)) + "px"
  }, "slow");
}

function autoplay() {
  interval = setInterval(function() {
    SlideRight();
  }, 3000);
}
autoplay();

我使用此代码循环滑动滑块

$('.slideinner-style').delay(3500).fadeOut(500, SlideRight);

但是它没有按预期工作。有什么建议吗？

$(function () {
    $('#myCarousel').carousel({
       interval: 2000,
    cycle: true,
    pause: "null"
    });
    
});

$('#myCarousel').hover(function() {
    $(this).carousel('pause');
}, function() {
    $(this).carousel('cycle');
});

希望这对您有所帮助。
