通过 ajax 调用刷新局部视图挂起应用程序

Question

MVC5 应用程序我每 5 秒刷新一次部分视图，但是几分钟后应用程序挂起，客户端浏览器错误

net::ERR_INSUFFICIENT_RESOURCES

调用局部的代码在这里

 function setupRefresh() {

    $.ajaxSetup({ cache: false });

    // ajax load partial view
    $("#PartialViewPlaceHolder").load("/testController/GetTestPartialView");
    // refresh count every 5 seconds
    $(function() {
        window.setInterval(setupRefresh, 5000);
    });

   }

我的部分代码是

    <div class="col-md-12">
    @if (Model.TestCount > 0)
    {

            <p class="alert alert-info">
                There are <strong>@Model.testCount</strong> widgets in this batch
            </p>
            @ShowButton()

    }
    else
    {
        <p class="alert alert-info">
            There are no widgets
        </p>
    }
</div>

 @helper ShowButton()

{ @Html.ActionLink("Do something", "GetPartialView", "TestController", new {@class = "modal-link btn btn-primary btn-lg btn-block"}) }

此片段必须在 setupRefresh() 之外

$(function() {
        window.setInterval(setupRefresh, 5000);
    });
