为什么沙漏工作不与谷歌浏览器同步AJAX请求？ [英] Why HourGlass not working with synchronous AJAX request in Google Chrome?

问题描述

我执行，其中第一我正在光标移动到等待状态（沙漏），然后我送一个synchrounous AJAX请求。之后得到我正在光标移动到默认状态响应的功能。

I am executing a function where first I am making cursor to wait state(hourglass) and then I am sending a synchrounous AJAX request .After getting the response I am making cursor to default state.

实际的code是这个..

The Actual Code is this..

//测试SMTP设置 功能TestSettings（） {     VAR buttonparams =新的对象（）;

// tests the smtp settings function TestSettings() { var buttonparams= new Object();

buttonparams.IsCommandButton = true;
buttonparams.ButtonId = "testsettings";
buttonparams.ButtonText = "Sending Test Mail...";
buttonparams.ButtonOrigText = "Test Settings";

if(buttonparams.IsCommandButton == true)
	HandleButtonStatus(true, buttonparams);

var request = function()
{
	var ret = SendForm(buttonparams);

	alert(ret);

}
window.setTimeout(request, 0);

}

功能SendForm（pButtonParams） {     VAR HTTP;     VAR FORMDATA;

function SendForm(pButtonParams) { var http; var formdata;

http = yXMLHttpRequest();

http.open("POST", "./", false);
http.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");	
http.setRequestHeader("Req-Type", "ajax");
formdata = xEncodePair("_object", "PrefMgr")+ "&";
formdata += xEncodePair("_action", "SmtpTest")+ "&";
formdata += GetEncodedFormData();	

http.send(formdata);

if(http.status == 200)
{	
	if(pButtonParams.IsCommandButton == true)
		HandleButtonStatus(false, pButtonParams);

	return (http.responseText);
}	
else
{

	return ("Error " + http.status + ": " + http.statusText);	
}

}

功能HandleButtonStatus（pIsButtonStatusChange，pButtonParams） {     VAR按钮= yById（pButtonParams.ButtonId）;

function HandleButtonStatus(pIsButtonStatusChange, pButtonParams) { var button = yById(pButtonParams.ButtonId);

if(pIsButtonStatusChange)
{
        document.body.style.cursor = "wait";
	button.value = pButtonParams.ButtonText;
	button.disabled = true;

}
else
{
	document.body.style.cursor = "default";
	button.disabled = false;
	button.value = pButtonParams.ButtonOrigText;
}

}

推荐答案

尝试分配：

var st = document.body.style;

然后参照 ST 的两种功能。这可能是在AJAX回调函数范围的问题。

and then refer to st in both functions. This could be a scope issue in AJAX callback function.

编辑：使用回叫功能恢复光标形状。不要忘记的情况下AJAX调用失败这样做。

Use callback function to restore cursor shape. Don't forget to do the same in case AJAX call fails.
