jq實(shí)時(shí)監(jiān)測(cè)窗口大小，來(lái)調(diào)用不用的swiper效果
時(shí)間：2023-07-02 訪問(wèn)量：0
在網(wǎng)站開(kāi)發(fā)過(guò)程中，我們用得很多的插件之一就是swiper,但是我們?cè)谧鲎笥叶鄠€(gè)slider切換的時(shí)候，當(dāng)換到手機(jī)端上的時(shí)候，我們需要切換顯示的個(gè)數(shù)。如果下圖：
比如PC端一行顯示4個(gè)圖片：
JS:
var swiper = new Swiper('.swiper-container', {
slidesPerView: 4,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
});
但是顯示在手機(jī)上不能顯示4個(gè)，需要顯示1個(gè)或者兩個(gè)。
var swiper = new Swiper('.swiper-container', {
slidesPerView: 1,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
});
那么我們就可以通過(guò)JS來(lái)監(jiān)聽(tīng)窗口的大小變化來(lái)調(diào)用不同的代碼。
代碼如下：
//打開(kāi)網(wǎng)頁(yè)時(shí)的寬度，必須保留
var windowsize = $(window).width();
if( windowsize > 768 ) { // 屏寬1330觸發(fā)
//主體
var swiper = new Swiper('.swiper-container', {
slidesPerView: 4,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
});
//主體
}else{
//主體
var swiper = new Swiper('.swiper-container', {
slidesPerView: 1,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
});
//主體
}
//監(jiān)測(cè)網(wǎng)頁(yè)時(shí)的寬度變化，以及實(shí)時(shí)更新
$(window).resize(function() {
windowsize = $(window).width();
if( windowsize > 768 ) { // 屏寬1330觸發(fā)
//主體
var swiper = new Swiper('.swiper-container', {
slidesPerView: 4,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
});
//主體
}else{
//主體
var swiper = new Swiper('.swiper-container', {
slidesPerView: 1,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
});
//主體
}
});以上是用JS來(lái)寫(xiě)的。現(xiàn)在提供另一方法 就是swiper自帶的效果：
var swiper = new Swiper('.swiper-container', {
slidesPerView: 4,
spaceBetween: 30,
loop: true,
autoplay:true,
speed: 500,
// 如果需要分頁(yè)器
pagination: {
el: '.swiper-pagination',
clickable :true,
},
// 如果需要前進(jìn)后退按鈕
navigation: {
nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
//響應(yīng)式個(gè)數(shù)
breakpoints: {
//當(dāng)寬度小于等于640時(shí)顯示
640: {
slidesPerView: 1,
spaceBetween: 20
},
//當(dāng)寬度小于等于768時(shí)顯示
768: {
slidesPerView: 3,
spaceBetween: 30
},
//當(dāng)寬度小于等于992時(shí)顯示
992: {
slidesPerView: 4,
spaceBetween: 30
}
}
});
