我的网站上有一个JQuery旋转器,带有幻灯片图像,我想让网站响应。我正在使用CSS媒体查询来完成它。当窗口宽度小于800px时,我想更改幻灯片宽度(在JS中定义)。 这么久,我做了这样的事情:
var responsiveSlideWidth;
if ($(window).width() < 800) {
responsiveSlideWidth = 700;
}
else {
responsiveSlideWidth = 960;
}
var defaults = {
container: '.rotatorWrapper',
animationduration: 1000,
slideWidth: responsiveSlideWidth
};
问题是它在页面重新加载后才起作用。这意味着:如果我调整窗口大小,则在重新加载页面之前它不起作用。
有什么建议吗?
感谢。
编辑:我的完整代码:
(function ($) {
$.fn.Rotator = function (options) {
var responsiveSlideWidth;
if ($(window).width() < 800) {
responsiveSlideWidth = 700;
}
else {
responsiveSlideWidth = 960;
}
var defaults = {
container: '.rotatorWrapper',
animationduration: 1000,
slideWidth: responsiveSlideWidth
};
options = $.extend(defaults, options);
elm = this;
var pageIndex = 0,
slideCount = 0;
var _init = function () {
slideCount = elm.find(options.container).children().children().length;
elm.find(options.container).children().width(slideCount * options.slideWidth);
_bindEvents();
_togglePager();
};
var _bindEvents = function () {
var jElm = $(elm);
jElm.find('.prev').on('click', _previous);
jElm.find('.next').on('click', _next);
};
var _next = function (e) {
e.preventDefault();
if (pageIndex >= 0 && pageIndex < slideCount - 1) {
pageIndex++;
elm.find(options.container).children().animate({
left: "-=" + options.slideWidth
}, options.animationduration);
}
_togglePager();
};
var _previous = function (e) {
e.preventDefault();
if (pageIndex <= slideCount) {
pageIndex--;
elm.find(options.container).children().animate({
left: "+=" + options.slideWidth
}, options.animationduration);
}
_togglePager();
};
var _togglePager = function () {
var $elm = $(elm);
var prev = $elm.find('.prev');
var next = $elm.find('.next');
console.log('slide count' + pageIndex + ' Page Index' + pageIndex)
if (pageIndex >= slideCount - 1) {
next.hide();
} else {
next.show();
}
if (pageIndex <= 0) {
prev.hide();
} else {
prev.show();
}
}
return _init(elm);
}
})(jQuery);
