我一直在寻找具有网格布局的砌体画廊,但没有找到它,所以我决定自己动手做。我使用带有网格布局的customElement,但是在动态分配网格行时会被阻塞。
我希望收到您的反馈,并帮助改善它。
我检测到的一些错误是:
的HTML
<masonry-gallery></masonry-gallery>
JS
class MasonryGallery extends HTMLElement {
items = [
{ image:'https://unsplash.it/200/100/' },
{ image:'https://unsplash.it/200/200/' },
{ image:'https://unsplash.it/200/300/' },
{ image:'https://unsplash.it/200/400/' },
{ image:'https://unsplash.it/200/300/' },
{ image:'https://unsplash.it/200/200/' },
{ image:'https://unsplash.it/200/100/' },
{ image:'https://unsplash.it/200/300/' },
{ image:'https://unsplash.it/200/700/' },
{ image:'https://unsplash.it/200/300/' },
{ image:'https://unsplash.it/200/200/' },
{ image:'https://unsplash.it/200/600/' },
{ image:'https://unsplash.it/200/100/' }
]
constructor() {
super()
this.attachShadow({ mode: 'open'})
this.create()
this.append()
}
create() {
this.style.display = 'grid'
this.style.gridTemplateColumns = 'repeat(auto-fill, 200px)'
this.style.gridTemplateRows = 'repeat(auto-fill, 1fr)'
this.style.gridGap = '1rem'
this.style.gridAutoFlow = 'row dense'
}
append() {
this.items.map(item => {
const div = document.createElement('DIV');
const image = document.createElement('IMG')
image.src = item.image
div.appendChild(image)
this.shadowRoot.appendChild(div)
div.style.gridRow = 'auto / span ' + [...String(image.height)][0]
})
}
}
customElements.define('masonry-gallery', MasonryGallery)
您的“错误”有以下原因:
可以通过以下append
方法来解决此问题:
append() {
let gap = parseInt(getComputedStyle(this).gridRowGap)
this.items.map(item => {
const div = document.createElement('DIV');
const image = document.createElement('IMG')
image.style.display = 'block';
image.src = item.image
div.appendChild(image)
image.onload = function() {
this.parentNode.style.gridRow = 'auto / span ' + ((this.height + gap)/(100 + gap));
}
this.shadowRoot.appendChild(div)
})
}
和更换gridRows
与gridAutoRows = '100px'
用于使垂直节奏均匀,并相应地调整图像的高度。
