在使用MVC时，向服务器端发送POST请求时有时需要传递数组作为参数值

下面使用例子说明，首先看一下Action

[HttpPost]
public ActionResult Test(List<string> model)
{
 return Json(null, JsonRequestBehavior.AllowGet);
}

方式一，构造表单元素，然后调用serialize()方法得到构造参数字符串

@{
 Layout = null;
}
<!DOCTYPE html>
<html>
<head>
 <meta name="viewport" content="width=device-width" />
 <title>Test</title>
</head>
<body>
 <div>
  <input type="button" id="btnAjax" value="发送请求" />
 </div>
 <script src="~/Scripts/jquery-1.10.2.min.js"></script>
 <script type="text/javascript">
  var tmp = '<input type="hidden" name="model" value="1" /><input type="hidden" name="model" value="2" />';
  $(function () {
   $("#btnAjax").click(function () {
    $.ajax({
     url: '@Url.Action("Test")',
     type: 'POST',
     data: $(tmp).serialize(),
     success: function (json) {
      console.log(json);
     }
    });
   });
  });
 </script>
</body>
</html>

调试模式监视参数，当点击按钮时，监视得到的参数如下

方式二：使用JavaScript对象作为参数传值，参数名是与Action方法对应的参数名，参数值是JavaScript数组

@{
 Layout = null;
}
<!DOCTYPE html>
<html>
<head>
 <meta name="viewport" content="width=device-width" />
 <title>Test</title>
</head>
<body>
 <div>
  <input type="button" id="btnAjax" value="发送请求" />
 </div>
 <script src="~/Scripts/jquery-1.10.2.min.js"></script>
 <script type="text/javascript">
  //var tmp = '<input type="hidden" name="model" value="1" /><input type="hidden" name="model" value="2" />';
  var array = ["abc","123"];
  $(function () {
   $("#btnAjax").click(function () {
    $.ajax({
     url: '@Url.Action("Test")',
     type: 'POST',
     data: {
      model:array
     },
     success: function (json) {
      console.log(json);
     }
    });
   });
  });
 </script>
</body>
</html>

方式三，使用Json作为参数请求，此时Ajax需要声明Content-Type为application/json

@{
 Layout = null;
}
<!DOCTYPE html>
<html>
<head>
 <meta name="viewport" content="width=device-width" />
 <title>Test</title>
</head>
<body>
 <div>
  <input type="button" id="btnAjax" value="发送请求" />
 </div>
 <script src="~/Scripts/jquery-1.10.2.min.js"></script>
 <script type="text/javascript">
  //var tmp = '<input type="hidden" name="model" value="1" /><input type="hidden" name="model" value="2" />';
  //var array = ["abc","123"];
  $(function () {
   $("#btnAjax").click(function () {
    $.ajax({
     url: '@Url.Action("Test")',
     type: 'POST',
     contentType:'application/json;charset=utf-8',
     data: JSON.stringify({
      model:["hello","welcome"]
     }),
     success: function (json) {
      console.log(json);
     }
    });
   });
  });
 </script>
</body>
</html>
