I had the same issue when updating a record. Inside the save() i was prepping the rawdata taken from the form to match the database format (doing a lot of mapping of enums values, etc), and this intermittently cancels the put request. i resolved it by taking out the data prepping from the save() and creating a dedicated dataPrep() method out of it. I turned this dataPrep into async and await all the memory intensive data conversion. I then return the prepped data to the save() method that i could use in the http put client. I made sure i await on dataPrep() before calling the put method:

等待dataToUpdate =等待dataPrep(); http。把(apiUrl dataToUpdate);

这解决了间歇性取消请求的问题。

在这能帮助任何人，我遇到取消状态时，我省略了返回false;在表单中提交。这导致ajax发送之后立即紧跟提交操作，这将覆盖当前页面。代码如下所示，在末尾返回重要的false。

$('form').submit(function() {

    $.validator.unobtrusive.parse($('form'));
    var data = $('form').serialize();
    data.__RequestVerificationToken = $('input[name=__RequestVerificationToken]').val();

    if ($('form').valid()) {
        $.ajax({
            url: this.action,
            type: 'POST',
            data: data,
            success: submitSuccess,
            fail: submitFailed
        });
    }
    return false;       //needed to stop default form submit action
});

希望这能帮助到别人。

当我用$调用a. js文件时，也发生了同样的情况。ajax，并发出一个ajax请求，我所做的是正常调用。

对我来说，这是一条错误的道路。我建议调试的第一步是看看你是否可以加载文件独立的ajax等。

对我来说，“取消”状态是因为文件不存在。奇怪为什么chrome浏览器不显示404。
