jQuery Ajax POSTing array to ASP.NET MVC Controller
提问by AgileMeansDoAsLittleAsPossible
I'm missing something here. I've got this jQuery JavaScript:
我在这里遗漏了一些东西。我有这个 jQuery JavaScript：
$.ajax({
type: "POST",
url: "/update-note-order",
dataType: "json",
data: {
orderedIds: orderedIds,
unixTimeMs: new Date().getTime()
}
});
Where orderedIdsis a JavaScript number array (e.g. var orderedIds = [1, 2]).
orderedIdsJavaScript 数字数组在哪里（例如var orderedIds = [1, 2]）。
The handling Controllermethod is:
处理Controller方法为：
[HttpPost]
public void UpdateNoteOrder(long[] orderedIds, long unixTimeMs)
{
...
}
When I put a Debugger.Break()in UpdateNoteOrder(), orderedIdsis nullin the Watch window. (unixTimeMs, however, has a numeric value.)
当我把一个Debugger.Break()在UpdateNoteOrder()，orderedIds是null在监视窗口。（unixTimeMs但是，有一个数值。）
How do I pass the number array through $.ajax()such that orderedIdsis a long[]in my controller?
我如何通过数字阵列通过$.ajax()这样orderedIds是long[]在我的控制？

Just set the traditionalparameter to true:
只需将traditional参数设置为true：
$.ajax({
type: "POST",
url: "/update-note-order",
dataType: "json",
traditional: true,
data: {
orderedIds: orderedIds,
unixTimeMs: new Date().getTime()
}
});
Since jquery 1.4 this parameter exists because the mechanism to serialize objects into query parameters has changed.
从 jquery 1.4 开始，这个参数存在是因为将对象序列化为查询参数的机制发生了变化。

you'll need to turn orderedId's into a param array, or the controller won't see it
您需要将orderedId 转换为参数数组，否则控制器将看不到它
$.param({ orderedIds: orderedIds });
in your code:
在您的代码中：
$.ajax({
type: "POST",
url: "/update-note-order",
dataType: "json",
data: {
orderedIds: $.param({ orderedIds: orderedIds }),
unixTimeMs: new Date().getTime()
}
});
