如果readystate = 4且status = 200则执行Jquery S.Ajax错误处理程序
我正在执行 $.ajax 调用，它返回 json 响应，一切看起来都很好，但不是调用成功处理程序，而是调用 $.ajax 错误处理程序，即使 readystate=4 和 status=200 也是如此。
$.ajax 调用是：-
$.ajax({
url: 'inc/ajax_printorder.asp',
type: "GET",
data: data,
contentType: "application/json; charset=utf-8",
dataType: "json",
cache: false,
success: function (sendresponse) {
var message = (typeof sendresponse.jsonresp) == 'string' ? eval('(' + sendresponse.jsonresp + ')') : sendresponse.jsonresp;
if (message[0].ok == '1') {
var order = window.open('', 'PrintWindow', 'width=600,height=600');
var html = '<html><head><title>Print Your Order</title></head><body><div id="myprintorder">' + $('<div />').append(message[0].msg) + '</div></body></html>';
order.document.open();
order.document.write(html);
order.document.close();
return false;
};
},
error: function (xhr, err) {
alert("readyState: " + xhr.readyState + "\nstatus: " + xhr.status);
alert("responseText: " + xhr.responseText);
}
});
从 Firebug 中，ajax 响应是：-
{"jsonresp":[{"__type":"sendresponse","ok":"1","msg":"<h1>Your www.sandwichlunchesnewbury.co.uk order on 02/05/2011 00:34:01</h1><p>Website order from www.sandwichlunchesnewbury.co.uk on 02/05/2011 00:34:01 from:- </p><table width="60%" style="border:1px solid blue;padding:5px;"><tr><td>Name</td><td> a </td></tr><tr><td>Phone</td><td> b </td></tr><tr><td>Email</td><td> </td></tr><tr><td>Business name</td><td> </td></tr><tr><td>Delivery address</td><td> c </td></tr><tr><td>Date food required</td><td> Monday, 02/05/2011 </td></tr><tr><td>Time food required</td><td> 10 Am </td></tr><tr><td> </td><td> </td></tr><tr><td>Just Sandwiches (standard)</td><td> </td></tr><tr><td>Just Sandwiches (gourmet)</td><td> </td></tr><tr><td>Just Baguettes (standard)</td><td> </td></tr><tr><td>Just Baguettes (gourmet)</td><td> </td></tr><tr><td>Gourmet Bread Sandwiches</td><td> 2 </td></tr><tr><td>Sausage rolls</td><td> </td></tr><tr><td>Cookie boxes</td><td> </td></tr><tr><td> </td><td> </td></tr><tr><td>Total price</td><td> £50.00 </td></tr><tr><td> </td><td> </td></tr><tr><td colspan="2">Other info & special instructions </td></tr><tr><td colspan="2"> </td></tr></table>"}]}
关于为什么会出错而不是成功的任何想法？
谢谢艾克斯
I'm doing an $.ajax call, which is returning a json response and all seems fine, but instead of the success handler being invoked, the $.ajax error handler is invoked even though the readystate=4 and the status=200.
The $.ajax call is:-
$.ajax({
url: 'inc/ajax_printorder.asp',
type: "GET",
data: data,
contentType: "application/json; charset=utf-8",
dataType: "json",
cache: false,
success: function (sendresponse) {
var message = (typeof sendresponse.jsonresp) == 'string' ? eval('(' + sendresponse.jsonresp + ')') : sendresponse.jsonresp;
if (message[0].ok == '1') {
var order = window.open('', 'PrintWindow', 'width=600,height=600');
var html = '<html><head><title>Print Your Order</title></head><body><div id="myprintorder">' + $('<div />').append(message[0].msg) + '</div></body></html>';
order.document.open();
order.document.write(html);
order.document.close();
return false;
};
},
error: function (xhr, err) {
alert("readyState: " + xhr.readyState + "\nstatus: " + xhr.status);
alert("responseText: " + xhr.responseText);
}
});
and from Firebug, the ajax response is:-
{"jsonresp":[{"__type":"sendresponse","ok":"1","msg":"<h1>Your www.sandwichlunchesnewbury.co.uk order on 02/05/2011 00:34:01</h1><p>Website order from www.sandwichlunchesnewbury.co.uk on 02/05/2011 00:34:01 from:- </p><table width="60%" style="border:1px solid blue;padding:5px;"><tr><td>Name</td><td> a </td></tr><tr><td>Phone</td><td> b </td></tr><tr><td>Email</td><td> </td></tr><tr><td>Business name</td><td> </td></tr><tr><td>Delivery address</td><td> c </td></tr><tr><td>Date food required</td><td> Monday, 02/05/2011 </td></tr><tr><td>Time food required</td><td> 10 Am </td></tr><tr><td> </td><td> </td></tr><tr><td>Just Sandwiches (standard)</td><td> </td></tr><tr><td>Just Sandwiches (gourmet)</td><td> </td></tr><tr><td>Just Baguettes (standard)</td><td> </td></tr><tr><td>Just Baguettes (gourmet)</td><td> </td></tr><tr><td>Gourmet Bread Sandwiches</td><td> 2 </td></tr><tr><td>Sausage rolls</td><td> </td></tr><tr><td>Cookie boxes</td><td> </td></tr><tr><td> </td><td> </td></tr><tr><td>Total price</td><td> £50.00 </td></tr><tr><td> </td><td> </td></tr><tr><td colspan="2">Other info & special instructions </td></tr><tr><td colspan="2"> </td></tr></table>"}]}
Any thoughts on why its going to error rather than success?
Thanks

您的响应 JSON 无效，除其他外，您需要转义双引号（
\"而不是"）。您没有发布错误文本（传递给error的err值），但我怀疑它是parsererror。我发现 JSONLint 对于确保接收/发送有效的 JSON 非常有用。
Your response JSON is invalid, among other things, you will need to escape the double quotes (
\"instead of"). You didn't post what the error text (the value oferras passed toerror) is but I suspect it'll beparsererror.I've found JSONLint to be very useful in ensuring I'm receiving/sending valid JSON.
