随机重定向到/未定义 [英] Random redirect to /Undefined

问题描述

我工作的一个内部MVC的网站。

I'm working on an internal MVC site.

问题：

突然，该网站已经开始重定向到本地主机/未定义在选择浏览器（Chrome浏览器，Opera和Safari）前/删除POST之后。这不会发生在Firefox或IE浏览器。

Suddenly the site has started redirecting to localhost/undefined in select browsers (Chrome, Opera, and Safari) before/after a delete POST. This does not happen in Firefox or IE.

采取的步骤：

我已经通过下面的JavaScript code无数次在Chrome上台阶（没有工作）和IE（工作）。似乎有没有什么区别比铬整理与随机重定向后，在code，它不叫其他的。

I've stepped through the following javascript code numerous times on Chrome(not working) and IE(working). There appear to be no difference other than Chrome finishing with a random redirect that is not called upon in the code.

jQuery的AJAX调用如下：

// Delete button clicked
function deleteEntity(e) {
    e.preventDefault();

    var name = $(this).attr("name");
    var index = $(".deleteEntity[name=" + name + "]").index($(this));
    var entityId = ko.utils.unwrapObservable(viewModel.model.peek()[index].ID);
    var data = { EntityID: entityId };

    viewModel.model.remove(viewModel.model.peek()[index]);

    if (entityId > 0) {
        $.ajax({
            url: "/" + name + "/Delete",
            type: "POST",
            data: data,
            dataType: 'json',
            async: true,
            success: function (data, textStatus, xhr) {
                alert(data);
            },
            error: function (xhr, textStatus, errorThrown) {
                // Decide later.
            }
        });
    }
}

$(document).on("click", ".deleteEntity", deleteEntity);

调试步骤

在开始在Ajax调用的线路断路。 - > 如果（entityId＆GT; 0）{

Starting at a break at the line of the ajax call. -> if (entityId > 0) {.

• 如果我按F8在这里通过我的休息时间在成功和错误的功能，它结束了不打任何断点，并重定向到本地主机/未定义没有联系服务器。
• 如果我打F10单步调试它会停在我的断点删除操作在服务器上。从那里，我在Visual Studio中按F5键，它删除选定的预期实体返回我对我在broswer断点。如果我从这里按F8也将达到成功，弹出成功的提示框。
• 如果我在broswer按F8按F5在Visual Studio之前，但它会立即重定向到本地主机/未定义。

• If I hit F8 here to pass through to my breaks at the success and error functions, it ends up not hitting either of the breakpoints and redirecting to localhost/undefined without contacting the server.
• If I hit F10 to step through it will stop at my breakpoint on the server in the delete action. From there I hit F5 in visual studio and it deletes the selected expected entity returning me to my breakpoint in the broswer. If I hit F8 from here it will hit success and popup the alert box with success.
• If I hit F8 in the broswer before hitting F5 in visual studio however it will instantly redirect to localhost/undefined.

问：有谁知道这个问题的由来？我GOOGLE了四周，发现有关的插件，所以我尝试禁用所有的（全2）非常类似的问题，并没有改变任何东西。

Question: Does anyone know the origin of this problem? I've googled around and found a very similar issue relating to plugins so I tried disabling all of the (a whole 2) and it did not change anything.

P.S。如果任何其他code段将有助于只是评论，我会添加它们。我已经在至少20次检查了我的行动。该删除是 [HttpPost] 但这样是我的更新和它的正常工作，在完全相同的方式。

p.s. if any other code snippets will be helpful just comment and I'll add them. I've checked my actions over at least 20 times. The Delete is an [HttpPost] but so is my Update and it's working fine in the same exact fashion.

推荐答案

我通过从我的删除操作的 [HttpPost] 属性在我的控制器解决了这个问题。 （我不得不添加JSON的回报，使得到但那只是因为它不再是一个post请求）。

I solved the problem by removing the [HttpPost] attribute from my Delete action in my controller. (I had to add the Json return to allow get but that was just because it was no longer a post request).

我的线索少，为什么它是导致这样的错误，并会要求一个独立的问题，在关于这一点。如果找到一个答案，我在这里将链接在这个岗位。

I am clue-less as to why it was causing such an error and will be asking a separate question in regards to that. If an answer is found I will link it here in this post.
