在使用MVC時，向伺服器端發送POST請求時有時需要傳遞數組作為參數值

下面使用例子說明，首先看一下Action

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

方式一，構造表單元素，然後調用serialize()方法得到構造參數字串

@{    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="發送請求" />    </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>

偵錯模式監視參數，當點擊按鈕時，監視得到的參數如下

方式二：使用JavaScript對象作為參數傳值，參數名是與Action方法對應的參數名，參數值是JavaScript數組

@{    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="發送請求" />    </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作為參數請求，此時Ajax需要聲明Content-Type為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="發送請求" />    </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>

上面的例子使用的是ASP.NET MVC 5
