我正在使用引导轮播并希望将其修改为始终适合窗口(或任何其他设备)的滑块。这是我的解决方案:
如果imageRatio > winRatio
那么
stretch images height to it's max
否则
stretch images width to it's max
当图像比例大于窗口比例时,我添加max-height:100%;max-width:none;
到图像中,当窗口比例大于图像比例时,我添加max-width: 100%; max-height: none;
长话短说,所有这些东西都有效,但是当我调整窗口图像比例和窗口比例时不知何故!这是`console.log(winRatio,imgRatio)的结果;
1.0709046454767726 1.5051546391752577 /* this is expected results but */
1.1124694376528117 1.1124694376528117 /* when i stop resizing */
我的 HTML:
<div class="row-fluid">
<div id="top-slider" class="carousel slide">
<!-- Carousel pattern mask -->
<div class="mask"></div>
<!-- Carousel items -->
<div class="carousel-inner">
<div class="active item"><img src="img/slider/slide01.jpg" alt="Slide 01" /></div>
<div class="item"><img src="img/slider/slide02.jpg" alt="Slide 02" /></div>
<div class="item"><img src="img/slider/slide03.jpg" alt="Slide 03" /></div>
</div>
<!-- Carousel nav -->
<div class="carousel-control">
<a class="left" href="#top-slider" data-slide="prev"></a>
<a class="right" href="#top-slider" data-slide="next"></a>
</div>
</div>
</div>
<!-- /site top slider -->
Javascript:
// DOM Ready
jQuery(document).ready(function($){
/* strech homepage top slider's slides to fit device screen
------------------------------------------------------------------- */
function fitSlider() {
var wH = $(window).height() - $('#top-header').height();
var wW = $(window).width();
var winRatio = wW / wH;
var imgH = $('#top-slider .carousel-inner').height();
var imgW = $('#top-slider .carousel-inner').width();
var imgRatio = imgW / imgH;
console.log(winRatio, imgRatio);
$('#top-slider').css('height', wH);
if ( imgRatio > winRatio )
{
$('#top-slider .carousel-inner .item img').addClass('fit-height');
}
else
{
$('#top-slider .carousel-inner .item img').removeClass('fit-height');
}
}
// On window resized fire this event
$(window).bind('resize',function() {
//Update slider
fitSlider();
});
// On window loaded fire this event
$(window).load(function() {
fitSlider();
});
});
