我正在使用 Swiper.js 库,但在通过 JavaScript 动态加载元素时触发“slideChange”事件时遇到问题。
这是我的水平和垂直滑动器初始化的地方:
var swiper = {
initialize : function() {
swiperH = new Swiper('.swiper-container-h', {
slidesPerView: 1,
preloadImages: false,
updateOnImagesReady: true,
lazy: true,
})
.on('slideChange', function () {
console.log('Swiped Horizonally');
});
swiperV = new Swiper('.swiper-container-v', {
direction: 'vertical',
slidesPerView: 1,
preloadImages: false,
updateOnImagesReady: true,
lazy: true,
effect: 'fade',
loop: true,
fadeEffect: {
crossFade: true
},
pagination: {
el: '.swiper-pagination-v',
clickable: true,
},
})
.on('slideChange', function () {
console.log('Swiped Vertically');
});
}
};
水平方向的'slideChange'触发的原因是因为它已经在html文件中:
<!-- Swiper -->
<div class="dash-container">
<div class="swiper-container swiper-container-h">
<div class="swiper-wrapper" id="swipeData">
</div>
</div>
</div>
现在,垂直幻灯片是通过 JavaScript 加载的,这就是垂直幻灯片的“slideChange”不会触发的地方。
function loadDresses(selectedDresses) {
return new Promise((resolve, reject) => {
$('#swipeData').html('');
for (var i = 0; i < selectedDresses.length; i++) {
var vScroll = '<div class="swiper-slide"><div class="swiper-container swiper-container-v"><div class="swiper-wrapper" style="height: 100%;">';
for (var j = 0; j < selectedDresses[i].images.length; j++) {
vScroll += '<div class="swiper-slide"><img src="' + selectedDresses[i].images[j] + '"/></div>';
}
vScroll += '<div class="swiper-slide" style="display:table;height:100%;width:100%;">';
vScroll += '</div></div></div><div class="swiper-pagination swiper-pagination-v">';
$('#swipeData').append(vScroll).trigger('create');
}
resolve(true);
});
}
此代码段发生错误:
.on('slideChange', function () {
console.log('Swiped Vertically');
});
有什么想法吗?谢谢!
编辑:
我已尝试以下方法来阻止它过早初始化,但仍然没有成功:
loadDresses(dresses).then(function(result) {
var t = setInterval(() => {
swiper.initialize();
clearInterval(t);
}, 5000);
});
最佳答案
这没有帮助吗?
var swiper = {
initialize : function() {
swiperH = new Swiper('.swiper-container-h', {
slidesPerView: 1,
preloadImages: false,
updateOnImagesReady: true,
lazy: true,
})
.on('slideChange', function () {
console.log('Swiped Horizonally');
});
swiperV = new Swiper('.swiper-container-v', {
direction: 'vertical',
slidesPerView: 1,
preloadImages: false,
updateOnImagesReady: true,
lazy: true,
effect: 'fade',
loop: true,
fadeEffect: {
crossFade: true
},
pagination: {
el: '.swiper-pagination-v',
clickable: true,
},
on: {
slideChange: function() {
console.log('Swiped Vertically');
}
}
});
}
};
