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>
上面的例子使用的是ASP.NET MVC 5
