当我使用ajax调用另一个php页面时
$.ajax({
url: '/coffee_note/ajax/coffeeN_list.php',
type: 'POST',
data: data,
success: function (msg) {
$('#shop').html(msg);
},
error: function (xhr) {
console.log(xhr);
}
});
但它在控制台中显示错误：
POST http://127.0.0.1/coffee_note/ajax/coffeeN_list.php 500 (Internal Server Error)
m.ajaxTransport.a.send @ jquery-1.11.3.min.js:5
m.extend.ajax @ jquery-1.11.3.min.js:5
refreshList @ coffeeN.js:20
(anonymous function) @ coffeeN.js:93
m.event.dispatch @ jquery-1.11.3.min.js:4
m.event.add.r.handle @ jquery-1.11.3.min.js:4
coffeeN.js:28 Object {readyState: 4, responseText: "", status: 500, statusText: "Internal Server Error"}
我不确定我的代码是否错误，但到目前为止我没有发现任何错误。
这是mysql错误报告：
