我正在使用Bootstrap Carousel,但是通过循环通过名为“ Capris”的数组,通过DOM
生成了Carousel的幻灯片。每个幻灯片上都有一个按钮,该按钮也特定于每个索引。
[我要做的是,当用户单击其中一个按钮时,它将按钮重定向到另一个HTML文件,并在另一个HTML页面上将相同的索引打印到DOM
。
除了将索引打印到第二个HTML文件上的DOM
之外,我已经做了所有事情。这是我的轮播和按钮的事件侦听器代码段:
const buyCapriBttn = () => {
for (let i = 0; i < capris.length; i++) {
document.querySelector(`#${capris[i].name}`).addEventListener('click', function () {generateProduct(capris[i])});
}
}
const capriCarousel = () => {
let domString = '';
for (let i = 0; i < capris.length; i++) {
if (i === 0) {
domString += `
<div class="carousel-item active">
<img class="d-block w-100" src="${capris[i].imageUrl}" alt="Capri 1">
<div class="d-flex justify-content-center">
<a id="${capris[i].name}" class="btn btn-primary capri-btn" href="/capris.html" role="button">Buy ${capris[i].name}</a>
</div>
<p class="capri-description">${capris[i].description}</p>
</div>
`;
} else if (i >= 1) {
domString += `
<div class="carousel-item">
<img class="d-block w-100" src="${capris[i].imageUrl}" alt="Capri 1">
<div class="d-flex justify-content-center">
<a id="${capris[i].name}" class="btn btn-primary capri-btn" href="/capris.html" role="button">Buy ${capris[i].name}</a>
</div>
<p class="capri-description">${capris[i].description}</p>
</div>
`;
} else;
}
printToDom("#carousel-items", domString);
buyCapriBttn();
}
单击按钮时,它将为该索引运行generateProduct
功能。这是运行该功能的代码段:
const generateProduct = (selectedPants) => {
domString = '';
console.log(selectedPants);
for (let i = 0; i < capris.length; i++) {
if (capris[i] === selectedPants) {
domString += `
<div id="caprisDom">
<img id="buycaprispic" src="${capris[i].imageUrl}">
<div id="nameandrating">
<h5 id="buycaprisname">${capris[i].name}</h5><h2>☆☆☆☆☆</h2>
</div>
<div class="caprisinfobox">
<p id="caprisinfo">${capris[i].description}</p>
<div class="sizeandprice">
<div id="sizeselector">
<label id="sizelabel">Size:</label>
<select name="sizelist" id="size">
</select>
</div>
<h3 id="price">$${capris[i].price}</h3>
</div>
<button id="cartbutton">Add to Cart</button>
</div>
</div>
`;
}
}
printToDom('#caprismain', domString);
}
我也有一个printToDom
函数,如果需要的话,也可以打印到这些ID。
注意:在本练习中,我试图not使用JQuery
非常感谢任何想法和帮助!
您是否只需要该项目的index位置?我可能会在a
声明中动态添加它。类似于<a id="${capris[i].name}" class="btn btn-primary capri-btn" href="/capris.html?index=${i}" role="button">Buy ${capris[i].name}</a>
因此它应该看起来像这样:
const capriCarousel = () => {
let domString = '';
for (let i = 0; i < capris.length; i++) {
if (i === 0) {
domString += `
<div class="carousel-item active">
<img class="d-block w-100" src="${capris[i].imageUrl}" alt="Capri 1">
<div class="d-flex justify-content-center">
<a id="${capris[i].name}" class="btn btn-primary capri-btn" href="/capris.html?index=${i}" role="button">Buy ${capris[i].name}</a>
</div>
<p class="capri-description">${capris[i].description}</p>
</div>
`;
} else if (i >= 1) {
domString += `
<div class="carousel-item">
<img class="d-block w-100" src="${capris[i].imageUrl}" alt="Capri 1">
<div class="d-flex justify-content-center">
<a id="${capris[i].name}" class="btn btn-primary capri-btn" href="/capris.html?index=${i}" role="button">Buy ${capris[i].name}</a>
</div>
<p class="capri-description">${capris[i].description}</p>
</div>
`;
} else;
}
printToDom("#carousel-items", domString);
buyCapriBttn();
}
然后,在另一页中,在您的js中,您将grab使用URLSearchParams选择查询,如下所示:
const urlParams = new URLSearchParams(window.location.search);
const myParam = urlParams.get('index');
