我这里有一个json文件,这个内容应该在引导卡内呈现。
[{
"scripts": {
"web3py": [
{
"thumbnail": "images/thumbnails/sendetherweb3py.png",
"scriptName": "send Native",
"description": "send native with web3py",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
},
{
"thumbnail": "images/thumbnails/sendtokenweb3py.png",
"scriptName": "send token",
"description": "send erc20 token with web3py",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
},
{
"thumbnail": "images/thumbnails/swapnativeweb3py.png",
"scriptName": "swap native token dex",
"description": "swap eth for erc20 token",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
},
{
"thumbnail": "images/thumbnails/swaptokenweb3py.png",
"scriptName": "swap erc20 token on dex",
"description": "swap erc20 token with erc20 token",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
}
],
"web3js": [
{
"thumbnail": "images/thumbnails/swaptokenethers.png",
"scriptName": "swap token on dex",
"description": "swap erc20 token with token on a dex",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
},
{
"thumbnail": "images/thumbnails/swapnativeethers.png",
"scriptName": "swap native",
"description": "swap native for token on dex",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
},
{
"thumbnail": "images/thumbnails/sendtokenethers.png",
"scriptName": "send ERC20 token",
"description": "send erc20 token with ethers",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
},
{
"thumbnail": "images/thumbnails/sendnativeethers.png",
"scriptName": "send native",
"description": "send Native ETH with ethers",
"link": "https://jsonformatter.org/img/tom-cruise.jpg"
}
]
}
}]
在脚本里面我有两个类别,web3py和web3js,其中有4个项目。现在我想在一行中渲染web3py,其中包含4张卡片,另一行中渲染web3js,其中也包含4张卡片。
如何基于json文件中的内容在Javascript中呈现引导卡?
我想动态地这样做,所以如果我添加更多的项目到web3py或web3js,我希望卡是动态创建的。
那么,使用javascript在一行中创建这4张卡片的最佳方法是什么呢?
卡片看起来像这样
<div class="card" style="width: 18rem;">
<img src=${thumbnail} class="card-img-top" alt="...">
<div class="card-body">
<h5 class="card-title">${scriptName}</h5>
<p class="card-text">${description}</p>
<a href=${link} class="btn btn-primary">Go somewhere</a>
</div>
</div>
这是我的Javascript文件
async function getScript(){
const scripts = await fetch('./scripts.json')
const response = await scripts.json()
//console.log(response[0])
const scripta = response[0]['scripts']['web3py']
const image = response[0]['scripts']['web3py'][0]['thumbnail']
const title = response[0]['scripts']['web3py'][0]['scriptName']
const description = response[0]['scripts']['web3py'][0]['description']
console.log(title)
let content = '';
scripta.forEach(p => {
content += `
<div id="keyBoard" class="col-md-4 mt-2">
<div class="card" style="width: 18rem;">
<img src="${image}" class="card-img-top img-fluid" alt="keyboard">
<div class="card-body">
<h5 class="card-title" id="itemName">${title}</h5>
<p class="card-text" id="itemDesc">${description}</p>
<p class="card-text"></p>
<a href="#" class="btn btn-primary" id="addCart">Add to cart</a>
</div>
</div>
</div>
`
});
document.querySelector("#shop").innerHTML = content;
}
getScript()
问题是该函数在一行中打印出第一项4次,而不是在一行中每次打印出1项

您可以使用嵌套循环遍历JSON数据,然后使用空变量构建HTML字符串。然后使用***insertAdjacentHTML***插入该HTML。代码中的附加注解可分解每一行的操作。
