在使用MVC時，向服務器端發送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，然后調用serialize()方法得到構造參數字符串

@{ 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="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>

調試模式監視參數，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>
