[英]How to make Coin Slider responsive?
After being created, the slider seems not to have a way to be resized, which is really bad for a responsive layout. 创建后,滑块似乎无法调整大小,这对于响应式布局确实很不利。
Is there a way to actually resize the Coin Slider plugin according to Twitter Bootstrap 3's media queries? 有没有一种方法可以根据Twitter Bootstrap 3的媒体查询实际调整Coin Slider插件的大小?
You might consider Coin Slider's demo as a fiddle. 您可能会认为Coin Slider的演示只是摆弄。
Indeed, there is no way to resize it with the current plugin version. 确实,无法使用当前插件版本来调整其大小。 So, I wrote a script to resize the Coin Slider (you can test it on Coin Slider's demo site):
因此,我编写了一个脚本来调整Coin Slider的大小(您可以在Coin Slider的演示站点上对其进行测试):
var resizeCoinSliderTo = function(coinSlider, toWidth, toHeight) {
var csColumns = 7;
var csRows = 5;
var imgWidth = toWidth;
var imgHeight = toHeight;
var cellWidth = imgWidth/csColumns;
var cellHeight = imgHeight/csRows;
var coinSliderId = coinSlider.attr("id");
coinSlider.css({
'width': imgWidth,
'height': imgHeight
});
$('.cs-'+coinSliderId).css({
'width': (cellWidth + 'px'),
'height': (cellHeight + 'px'),
'background-size': (imgWidth + 'px ' + imgHeight + 'px')
}).each(function() {
var cellOffsets = $(this).attr("id").replace("cs-"+coinSliderId,"");
var hOffSet = cellHeight * (Math.floor(parseInt(cellOffsets[0])-1) % csRows);
var wOffSet = cellWidth * (parseInt(cellOffsets[1])-1);
$(this).css({
"left": (wOffSet + 'px'),
"top": (hOffSet + 'px'),
"background-position": ((-wOffSet) + 'px ' + (-hOffSet) + 'px')
});
});
$('#cs-navigation-'+coinSliderId).children("a").css("top", (((imgHeight/2)-15)+'px'));
};
So, we just need to call the created resizeCoinSliderTo
after each media queries breakpoints, handling the resize, without losing its ratio, to fit the screen properly: 因此,我们只需要在每个媒体查询断点之后调用创建的
resizeCoinSliderTo
,即可在不丢失其比例的情况下处理调整大小以正确适合屏幕:
<span id="mq-detector">
<span class="visible-xs"></span>
<span class="visible-sm"></span>
<span class="visible-md"></span>
<span class="visible-lg"></span>
</span>
#mq-detector {
visibility: hidden;
}
var coinSlider = $("#coin-slider");
var baseWidthDisplay = undefined;
var baseHeightDisplay = undefined;
var currentRatio = undefined;
var mqRatios = [0.75, 0.95, 0.8, 1];
var mqDetector = $("#mq-detector");
var mqSelectors = [
mqDetector.find(".visible-xs"),
mqDetector.find(".visible-sm"),
mqDetector.find(".visible-md"),
mqDetector.find(".visible-lg")
];
var checkCoinSliderForResize = function() {
for (var i = 0; i <= mqSelectors.length; i++) {
if (mqSelectors[i].is(":visible")) {
if (currentRatio == undefined) {
baseWidthDisplay = parseInt(coinSlider.css("width"));
baseHeightDisplay = parseInt(coinSlider.css("height"));
}
if (i == 0) {
var specialWidth = Math.floor(parseInt($("body").css("width"))*0.75);
if (specialWidth < 300){
specialWidth = 300;
}
var specialHeight = Math.floor(baseHeightDisplay * specialWidth / baseWidthDisplay);
resizeCoinSliderTo(coinSlider, specialWidth, specialHeight);
}
if (currentRatio != mqRatios[i]) {
currentRatio = mqRatios[i];
if (i > 0) {
resizeCoinSliderTo(coinSlider, baseWidthDisplay*currentRatio, baseHeightDisplay*currentRatio);
}
}
break;
}
}
};
$(window).on('resize', checkCoinSliderForResize);
checkCoinSliderForResize();
Make sure to place all JavaScript code after the DOM is ready, and after the coinslider was created. 确保在DOM准备就绪后以及创建coinslider之后放置所有JavaScript代码。
