我有一個全局的ajax錯誤處理程序，即使xhr.status為200，xhr.statusText為“OK”并且xhr.responseText是我的JSON字符串，它仍會運行。這在firefox和IE中發生。

$.ajax({

data: {

method: "getRequestDetails",

loggedInUsername: loggedInUsername,

search: search

},

success: function(data){

var arrayObject = eval("(" + data + ")")['DATA'];

if (arrayObject.length == 0){

alert("That search term returned no results");

} else {

callBeforeShow("Results");

$.each(arrayObject, function(index, value){

showJSON(value, "Results");

});

callAfterShow("Results");

}

}

});

$(document).ajaxError(function(event, XMLHttpRequest, ajaxOptions, thrownError){

var errorMessage = "Ajax Error\n";

errorMessage += "Type: " + ajaxOptions.type + "\n";

errorMessage += "Requesting Page: " + ajaxOptions.url + "\n";

errorMessage += "Status: " + XMLHttpRequest.status + " - " + XMLHttpRequest.statusText + "\n";

errorMessage += "Error Thrown: " + thrownError

alert(errorMessage);

});

在IE中，這表示XMLHttpRequest尚未就緒，而在Firefox中則返回

“AJAX錯誤”

“類型：POST”

“請求頁面：something.CFC”

“狀態：200 - 好”

“錯誤拋出：未定義”

所以我的工作是使用

$(document).ajaxComplete(function(event, XMLHttpRequest, ajaxOptions, errorThrown){

if (XMLHttpRequest.status != 200){

var errorMessage = "Ajax Error\n";

errorMessage += "Type: " + ajaxOptions.type + "\n";

errorMessage += "Requesting Page: " + ajaxOptions.url + "\n";

errorMessage += "Status: " + XMLHttpRequest.status + " - " + XMLHttpRequest.statusText;

alert(errorMessage);

}

});

修改

* 這只發生在某些場合。它大部分時間都有效，但有時會運行$ .ajaxError() *

的EIDT

{"COLUMNS":["ID","SUMMARY_SPEC","TOTAL_EFFORT","EFFORT_HISTORY","LOG_HISTORY"],"DATA":[[816,"test only","2 Minutes - Last Updated: 09\/12\/2010",{"COLUMNS":["CC_ID","RECORD_ID","USER_ID","USER_NAME","EFFORT_DATE","EFFORT_DAYS","EFFORT_HRS","EFFORT_MINS","EFFORT_TOT_HRS"],"DATA":[[816,496,"ruhlet","Tim Ruhle","December, 09 2010 00:00:00",0,0,1,0.0167],[816,497,"ruhlet","Tim Ruhle","December, 08 2010 00:00:00",0,0,1,0.0167]]},{"COLUMNS":["CC_ID","RECORD_ID","USER_ID","USER_NAME","LOG_DT","LOG_ENTRY"],"DATA":[]}]]}{"COLUMNS":["ID","SUMMARY_SPEC","TOTAL_EFFORT","EFFORT_HISTORY","LOG_HISTORY"],"DATA":[[816,"test only","2 Minutes - Last Updated: 09\/12\/2010",{"COLUMNS":["CC_ID","RECORD_ID","USER_ID","USER_NAME","EFFORT_DATE","EFFORT_DAYS","EFFORT_HRS","EFFORT_MINS","EFFORT_TOT_HRS"],"DATA":[[816,496,"ruhlet","Tim Ruhle","December, 09 2010 00:00:00",0,0,1,0.0167],[816,497,"ruhlet","Tim Ruhle","December, 08 2010 00:00:00",0,0,1,0.0167]]},{"COLUMNS":["CC_ID","RECORD_ID","USER_ID","USER_NAME","LOG_DT","LOG_ENTRY"],"DATA":[]}]]}{"COLUMNS":["ID","SUMMARY_SPEC","TOTAL_EFFORT","EFFORT_HISTORY","LOG_HISTORY"],"DATA":[[816,"test only","2 Minutes - Last Updated: 09\/12\/2010",{"COLUMNS":["CC_ID","RECORD_ID","USER_ID","USER_NAME","EFFORT_DATE","EFFORT_DAYS","EFFORT_HRS","EFFORT_MINS","EFFORT_TOT_HRS"],"DATA":[[816,496,"ruhlet","Tim Ruhle","December, 09 2010 00:00:00",0,0,1,0.0167],[816,497,"ruhlet","Tim Ruhle","December, 08 2010 00:00:00",0,0,1,0.0167]]},{"COLUMNS":["CC_ID","RECORD_ID","USER_ID","USER_NAME","LOG_DT","LOG_ENTRY"],"DATA":[]}]]}

最新版本的firebug將其識別為json。
