原型 Ajax 对象实际上并未在 IE 8 中发出请求

我有一个包含以下 javascript 代码的 JSP 页面：

var refreshAjax = {};
function refreshDataOnClickHandler()
    {
        Event.stopObserving($("refreshdata"), "click", refreshDataOnClickHandler);
        refreshAjax = new Ajax.Request("/Locator",
                            {method: "get",
                            onSuccess: onRefreshDataSuccessHandler,
                            onFailure: onRefreshDataFailureHandler,
                            parameters: {
                                            serviceCenter: $("servicecenterselect").getValue(),
                                            action: "RefreshData"
                                        }
                            });
    }

function onRefreshDataSuccessHandler(response)
    {
        $("dashboardmessage").update("Data Refreshed.");
        $("mapRefresh").src = "Images/RefreshData.png";
        refreshAllStopsAndTrucks();
        Event.observe($("refreshdata"), "click", refreshDataOnClickHandler);
    }

Event.observe($("refreshdata"), "click", refreshDataOnClickHandler);

$("refreshdata") 解析为锚标记。 “/Locator”解析为 Java Servlet。我使用的是 IE 8。我正在使用原型 1.6.1。

我第一次加载页面并单击“refreshdata”时，Servlet 被正确调用，并且我得到了预期的响应。每当我点击“refreshdata”锚点时，Javascript 似乎都会执行调用的步骤，甚至表明它得到了响应。然而，servlet 从未被实际调用过。实际上没有发送任何响应。

让它再次正常工作的唯一方法是关闭 IE 8 并重新启动。

这在 Chrome 和 Firefox 上可以正常工作。有谁知道 IE 浏览器有什么奇怪之处导致它无法在 IE 中运行？

I have a JSP page with the following javascript code:

var refreshAjax = {};
function refreshDataOnClickHandler()
    {
        Event.stopObserving($("refreshdata"), "click", refreshDataOnClickHandler);
        refreshAjax = new Ajax.Request("/Locator",
                            {method: "get",
                            onSuccess: onRefreshDataSuccessHandler,
                            onFailure: onRefreshDataFailureHandler,
                            parameters: {
                                            serviceCenter: $("servicecenterselect").getValue(),
                                            action: "RefreshData"
                                        }
                            });
    }

function onRefreshDataSuccessHandler(response)
    {
        $("dashboardmessage").update("Data Refreshed.");
        $("mapRefresh").src = "Images/RefreshData.png";
        refreshAllStopsAndTrucks();
        Event.observe($("refreshdata"), "click", refreshDataOnClickHandler);
    }

Event.observe($("refreshdata"), "click", refreshDataOnClickHandler);

The $("refreshdata") resolves to an anchor tag.
"/Locator" resolves to a Java Servlet.
I'm using IE 8.
I'm using Prototype 1.6.1.

The first time I load the page and click "refreshdata" the Servlet is called correctly and I get the expected response. Every other time I click the "refreshdata" anchor the Javascript seems to go through the steps of making the call and even indicates that it gets a response. However, the servlet is never actually called. No response is actually sent.

The only way to get it to work correctly again is to shut down IE 8 and restart it.

This works correctly on Chrome and Firefox. Does anyone know what strangeness of the IE browser is keeping this from working in IE?
