我有这样的jQuery代码:
$(document).ready(function() {
$('.btn-create-post-card').on('click', function(event) {
event.preventDefault();
let form_data = new FormData(),
file = $('.input_file_button');
// if(!file.val()) {
// alert('Please select postcard you want to send')
// }
form_data.append("file", file.prop('files')[0]);
$.ajax({
url: "/sendEmail",
dataType: 'multipart/form-data',
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post',
success: function(data) {
alert('OK');
},
error: function(error, status) {
console.log('here');
console.log(error);
alert(error);
}
});
});
});
而且我得到了错误:
控制台输出为:
如您所见，响应是成功的，并且我以前使用jQuery AJAX调用很多次，并且从未遇到过此类问题。
更新:
控制台输出:

最佳答案
我不认为严格模式是错误，只是控制台无法在严格模式下获取arguments数组的内容。状态为200，因此看起来像ajax调用正常工作，但是响应文本显示为“无法上传文件”，因此我认为错误是在服务器端。
使用TypeError更新示例:
该TypeError仅表示控制台在使用严格模式时无法获取arguments数组的值。这不是代码错误。图片中的简单示例对此进行了演示。
关于javascript - 在严格模式下可能无法访问TypeError : 'caller' , 'callee'和 'arguments'属性，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/52298691/
