我只是环路我的Ajax调用，直到12030错误消失。报告错误，作为一个bug 这里

有谁知道是否有更好的修复...因为这需要时间循环。我读这是一个已知的问题与IE浏览器，它产生间歇性的错误12030作为阿贾克斯的状态。

  VAR阿贾克斯= {
    createAjaxObject：函数（）
    {
        VAR请求;
        尝试
        {
            要求=新XMLHtt prequest（）;
        }
        赶上（错误）
        {
            尝试
            {
                要求=新的ActiveXObject（MSXML2.XMLHTTP）;
            }
            赶上（错误）
            {
                尝试
                {
                    要求=新的ActiveXObject（Microsoft.XMLHTTP）;
                }
                赶上（错误）
                {
                    请求= FALSE;
                }
            }
        }
        返回请求;
    }，

    useAjaxObject：功能（路径，参数，ajax_func，html_div）
    {
        VAR对象=新Ajax.createAjaxObject（）;
        object.open（POST，路径，真实）;
        object.setRequestHeader（内容型，应用程序/ x-WWW的形式urlen codeD）;
        object.setRequestHeader（内容长度，param.length）;
        object.setRequestHeader（连接，关闭）;
        object.onreadystatechange =功能（）
        {
            如果（this.readyState === 4）
            {
                如果（this.status === 200）
                {
                    ajax_func（this.responseText，html_div）;
                }
                其他
                {
                    Ajax.repeatUseAjaxObject（路径，参数，ajax_func，html_div）;
                    返回false;
                }
            }
        };
        object.send（参数）;
        返回true;
    }，
    repeatUseAjaxObject：功能（路径，参数，ajax_func，html_div）
    {
        VAR状态=假，
            数= 1;
        而（州===假放;＆安培; COUNT＆LT; = 5）
        {
            状态= Ajax.useAjaxObject（路径，参数，ajax_func，html_div）;
            如果（计数！== 1）
            {
                警报（Ajax对象使用失败'）;
            }
        算上++;
        }
        返回的状态;
    }
 

解决方案

我有这个同样的问题，我找到了解决方法，只要AJAX请求是异步的。对于我的作品

解决的办法是包装在AJAX调用一个的setTimeout 为0的延迟调用。

这似乎工作的时间100％的我。

我也验证了我的同事之一的12030错误仍然出现在Internet Explorer 9中，也是如此。

＆LT;咆哮＆GT;所以比利G和公司认为合适的为我们提供了新的新城的接口，但它们不能被人打扰，以解决他们的所有Web程序员必须支持＆LT浏览器; /咆哮＆GT;

I just loop my Ajax call until the 12030 error goes away. The error is reported as a bug here

Does anyone know if there is a better fix...as this takes up time to loop. I read this was a known issue with IE that it intermittently produces 12030 errors as that Ajax status.

var Ajax = {
    createAjaxObject: function()
    {
        var request;
        try
        {
            request = new XMLHttpRequest();
        }
        catch(error)
        {
            try 
            {
                request = new ActiveXObject("Msxml2.XMLHTTP");
            }
            catch(error)
            {
                try
                {
                    request = new ActiveXObject("Microsoft.XMLHTTP");
                }
                catch(error)
                {
                    request = false;
                }
            }
        }
        return request;
    },

    useAjaxObject: function( path, param, ajax_func, html_div )
    {
        var object = new Ajax.createAjaxObject();
        object.open( "POST", path, true );
        object.setRequestHeader( "Content-type", "application/x-www-form-urlencoded" );
        object.setRequestHeader( "Content-length", param.length );
        object.setRequestHeader( "Connection", "close" );
        object.onreadystatechange = function()
        {
            if( this.readyState === 4 )
            {
                if( this.status === 200 )
                {
                    ajax_func( this.responseText, html_div );
                }
                else
                {
                    Ajax.repeatUseAjaxObject( path, param, ajax_func, html_div );
                    return false;
                }
            }
        };
        object.send( param );
        return true;
    },
    repeatUseAjaxObject: function( path, param, ajax_func, html_div )
    {
        var state = false,
            count = 1;
        while(state === false && count <= 5)
        {
            state = Ajax.useAjaxObject( path, param, ajax_func, html_div );
            if( count !== 1 )
            {
                alert( 'Ajax Object Use Failed ');
            }
        count++;
        }
        return state;
    }

I have this same problem, and I found a solution that works for me as long as the AJAX request is asynchronous.

The solution is to wrap the AJAX call in a setTimeout call with a delay of 0.

This seems to work 100% of the time for me.

I also verified with one of my co-workers that the 12030 error still occurs in Internet Explorer 9, as well.
