Getting TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode
提问by Bogdan Dubyk
I have such jQuery code:
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);
}
});
});
});
And I'm getting error:
我收到错误：
TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them
at Function.remoteFunction (:2:14)
TypeError: 'caller'、'callee' 和 'arguments' 属性可能无法在严格模式函数或
在 Function.remoteFunction调用它们的参数对象上访问(:2:14)
Console output is: 
控制台输出是：
As you can see response is successful and I used jQuery AJAX calls a lot before and never had such issue.
如您所见，响应是成功的，我以前经常使用 jQuery AJAX 调用，但从未遇到过这样的问题。

回答by Jacob Mouka
I don't think strict mode is the error, it's just that the console can't get the contents of the arguments array in strict mode. The status is 200 so it looks like the ajax call worked, but the response text says "can't upload file", so I think the error is on the server side.
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参数数组的内容。状态为 200，因此看起来 ajax 调用有效，但响应文本显示“无法上传文件”，因此我认为错误出在服务器端。
Update with TypeError example:
更新 TypeError 示例：
That TypeError just says the console can't get the values the arguments array when using strict mode. It's not an error with the code. The simple example in the image demonstrates this.
TypeError 只是说控制台在使用严格模式时无法获取参数数组的值。这不是代码错误。图像中的简单示例演示了这一点。

okay, I found the issue. The issue was in dataType: 'multipart/form-data',and after I remove it all is working. I think it worked on another machine because browser version on that machine does not support strict mode. Thanks for the help
好的，我发现了问题。问题出dataType: 'multipart/form-data',在我删除后，一切正常。我认为它在另一台机器上工作，因为那台机器上的浏览器版本不支持严格模式。谢谢您的帮助
