制作一个ajax，所以当我点击这个Link1按钮时，我需要清空products_list div中的内容
<button type="w3-button">Link1</button>
请帮助我了解如何在单击link1按钮时进行ajax调用，以清空product_list中的产品
下面的代码包含一个javascript来清除products_list的内容，但它不起作用
PHP 文件
<?php
session_start(); //start session
include("config.inc.php"); //include config file
?>
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Stores</title>
<link href="style/style1.css" rel="stylesheet" type="text/css">
<link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css">
</head>
<body>
<div align="center">
<h3>Products</h3>
</div>
<script>
$(document).on("click", ".w3-button", function() {
$('.products-wrp').html('')
// $("#products_list").html();
});</script>
<?php
//List products from database
$results = $mysqli_conn->query("SELECT product_name, product_desc, product_code, product_image, product_price FROM products_list");
//Display fetched records as you please
$products_list = '<ul id ="products_list" class="products-wrp">';
while($row = $results->fetch_assoc()) {
$products_list .= <<<EOT
<li>
<form class="form-item">
<h4>{$row["product_name"]}</h4>
<div>
<img src="images/{$row["product_image"]}" height="62" width="62">
</div>
<div>Price : {$currency} {$row["product_price"]}<div>
</form>
</li>
EOT;
}
$products_list .= '</ul></div>';
echo $products_list;
?>
</body>
</html>
最佳答案
检查下面的代码，该代码将在 Ajax 请求失败时清空 div -
function getFailOutput() {
$.ajax({
url:'myAjax.php',
success: function (response) {
console.log(data, response);
$('#output').html(response);
},
error: function () {
//Empty Output Div ON Error Returned From Ajax Request
$('#output').html('');
},
});
return false;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" onclick="return getSuccessOutput();"> test success </a> | <a href="#" onclick="return getFailOutput(); return false;"> test failure</a>
<div id="output">waiting for action</div>关于javascript - 使用ajax调用清空div，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44097690/
