我已经为图像滑块创建了自定义插件。就像显示没有图像的传递参数。
一旦看到最后一张图像,如何停止动画播放?有时也与先前的点击有关。帮我优化代码。
的CSS
.imgpresentation {
width: 520px;
height: 110px;
overflow: hidden;
border: 1px solid #ddd;
position: relative;
}
.imgpresentation img {
float: left;
padding: 5px;
}
.imgpresentation .prev {
left: 0;
position: absolute;
top: 40%;
}
.imgpresentation .next {
right: 0;
position: absolute;
top: 40%;
}
.slidethemimgpresentation {
position: absolute;
}
JS
<script>
$.fn.imgSlider = function(nImages) {
var imgW = $(this).find('img').outerWidth(),
imgH = $(this).find('img').outerHeight(),
imgL = $(this).find('img').length,
that = $(this),
container = that.find('.slidethemimgpresentation');
that.append('<a href="#" class="prev">Previous</a>'+
' <a href="#" class="next">Next</a>').css({
'width': nImages * imgW,
'height': imgH
});
container.css({
'width': imgW * imgL
});
imgW = nImages * imgW;
that.find('.next').on('click', function() {
var currLeft = parseInt(container.css('left'));
currLeft += -imgW;
container.animate({
'left': currLeft
});
return false;
});
that.find('.prev').on('click', function() {
var currLeft = parseInt(container.css('left'));
if (currLeft == 0) {
return false;
}
currLeft += imgW;
container.animate({
'left': currLeft
});
return false;
});
};
$(document).ready(function() {
$('#imgpresentation').imgSlider(2);
$('#imgpresentation2').imgSlider(3);
$('#imgpresentation3').imgSlider(4);
$('#imgpresentation4').imgSlider(1);
});
</script>

最佳答案
那是一个有点棘手的方法。因为它不是由数组驱动的,所以每次都移动容器+ =X。
您需要检查if( container.style.left + imgW > totalWidth )
要调试,请尝试使用console.log( container.style.left )
我建议使用现有的滑块,iDangerio.us Swiper的API很好。
另外,这有点低效,不是太重要,因为它仅在init上运行。
var imgW = $(this).find('img').outerWidth(),
imgH = $(this).find('img').outerHeight(),
imgL = $(this).find('img').length,
that = $(this),
container = that.find('.slidethemimgpresentation')
只解析一次jquery对象将是一种更好的做法,并且效率更高。
var that = $(this),
img = that.find('img'),
imgW = img.outerWidth(),
imgH = img.outerHeight(),
imgL = img.length,
container = that.find('.slidethemimgpresentation'),
totalWidth = imgW * imgL;
