我使用的是Windows10的机器上WAMP v.2.5。我的项目是一个运行MySQL数据库的PHP项目。它包含许多AJAX调用，这些调用很好。我有一个具体的电话，但是这给我一个'意外的输入结束'错误。Ajax调用不等待服务器响应
的呼叫从一个视图中进行，是针对全球的AJAX处理PHP脚本，将请求转发给控制器，然后请求的响应模型。适当的模型方法正在被解雇。该方法包含错误检查，并将为空结果抛出异常。数据库中的数据库查询有效，并在控制台中使用时返回结果。然而，10次中有9次，ajax fn会在没有接收/读取查询结果的情况下完成，从而产生上述错误。有时它会正常工作。
当放置一个活的服务器上，一切正常，因为它应该。就好像脚本在本地计算机上运行得太快，以等待数据库响应或抛出任何异常。
谁能告诉我如何正确地检验所发生的事情，或有解决上述问题？
编辑：
小道受影响的代码：
$(document).ready(function()
{
//some code
updateFilteredScheduleList();
//some code
});
function updateFilteredScheduleList()
{
var opts = $.extend(true, {}, dialogOptions);
getFilteredScheduleResults()
.done(function(returnedData)
{
var returnedDataObj = parseAjaxJSONResponse(returnedData);
if(returnedDataObj.hasOwnProperty('success'))
buildScheduleList(returnedDataObj.response);
})
.error(function(xhr, options, error)
{
opts.message = error;
displayDialog(opts);
return false;
});
}
function getFilteredScheduleResults()
{
var values = getFilterValues();
values.controller = 'WSVisits';
values.method = 'getFilteredScheduleResults';
console.log(values);
return $.ajax({
type: 'post',
cache: false,
data: values,
url: controllersAjaxPath
});
}
function getFilterValues()
{
var values = {};
//get values of view filters
return values;
}
function parseAjaxJSONResponse(data)
{
var opts = $.extend(true, {}, dialogOptions);
try
{
var tmp = JSON.parse(data);
if(tmp.hasOwnProperty('error'))
{
opts.message = tmp.error;
displayDialog(opts);
return false;
}
return tmp;
}
catch(e)
{
opts.message = e.message;
displayDialog(opts);
return false;
}
}
PHP方法（稍微改动过）：

你能告诉我你的Ajax代码？ – rahul
请添加包含AJAX调用的jquery代码。 –
@Plum我添加了相关的jquery函数。我将添加PHP方法也... – Eamonn
