[英]Fetching data using ajax and inserting in html using plain javascript
I have fetched data from my php/products.php
file using ajax and have a html
file that I have already styled. 我已经使用Ajax从我的
php/products.php
文件中获取了数据,并且有一个已经设置样式的html
文件。 How can I insert the data I have fetched from the products.php
file in the html
page? 如何在
html
页面中插入从products.php
文件获取的数据?
Most of my search results are based on jQuery. 我的大部分搜索结果都基于jQuery。
The containers I've used are the containers styled in the css
file. 我使用的容器是
css
文件中样式设置的容器。
The HTML HTML
<div class="container">
<header class="header">
<center>
<h1>Products</h1>
</center>
</header>
<hr>
<div id="products" class="products"></div>
<button id="loadButton" class="btn">Load more</button>
</div>
The JS JS
var loadBtn = document.getElementById('loadButton');
loadBtn.addEventListener('click', fetchProducts);
function fetchProducts() {
var xhr = new XMLHttpRequest;
xhr.open('GET', `php/products.php?${q}`, true);
xhr.onload = function () {
if (this.status == 200) {
var products = JSON.parse(this.responseText);
var output, i;
for (i = 0; i < products.length; i++) {
output += `
<div id="pCard" class="p-card">
<p id="pName" class="p-name">${products[i].name}</p>
<p id="pAbout" class="p-about">${products[i].description}</p>
</div>
`;
}
console.log(products);
document.getElementById('products').innerHTML = output;
}
}
xhr.send();
}
The PHP 的PHP
include 'config.inc.php';
$sqlFetch = "SELECT id,item_name,item_description FROM items ORDER BY id ASC LIMIT 3";
$result = mysqli_query($connection, $sqlFetch);
$products = mysqli_fetch_all($result, MYSQLI_ASSOC);
echo json_encode($products);
I expect the code to parse the containers containing the product name and description to the products container in the HTML page. 我希望代码将包含产品名称和描述的容器解析为HTML页面中的产品容器。 On clicking the
loadBtn
I want three more products to be loaded on the webpage Instead am getting an error from the console. 在单击
loadBtn
我希望在网页上再加载三个产品,相反从控制台收到错误消息。
The issue was at the php/products.php?${q}
on the JS
file. 问题出在
JS
文件上的php/products.php?${q}
。
I was also targeting name
and description
instead of item_name
and item_description
. 我也定位
name
和description
而不是item_name
和item_description
。
`
<div id="pCard" class="p-card">
<p id="pName" class="p-name">${products[i].name}</p>
<p id="pAbout" class="p-about">${products[i].description}</p>
</div>
`;
