或者你可以在这里看到我的代码

这是我的HTML

        <div class="carouselBg">
            <p id="demoSliderFirst" class="textSliders"> 
                Life must be lived forwards, but can only be understood backwards.  
            </p>
        </div>

这是我的CSS

.carouselBg{
   min-height: 300px;
   max-width: 700px;
   position: relative;
   top: 70px;
   color: #fff;
   background-color: #AC8157;
}
.textSliders{
  font-size: 24px;
  color: #fff;
  text-align: center;
  padding:50px;
  padding-top:130px;
}

这是我的JQUERY

var demoSlider1 = $('#demoSliderFirst');
var DemoSliderSet1 = [
'Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment',
'What screws us up the most in life is the picture in our head of how it is supposed to be.',
'Life shrinks or expands in proportion to one’s courage.'];
var index1 = 0;

function demoSliderCarousel1(){

    var newDemoSliderSet1 = DemoSliderSet1[index1];

    demoSlider1.fadeOut('400',function(){
        demoSlider1[0].innerHTML = newDemoSliderSet1;
    }).fadeIn('400');


    index1++;

    if(index1 >= DemoSliderSet1.length){
        index1 = 0;
    }

}

setInterval(demoSliderCarousel1,4000);
