我必须使用ajax将批量数组值传递给后面的代码(cs)我已经研究了很多并且使用了这段代码但它对我来说没有用,下面是我使用的代码,我需要传递批量数组使用ajax
在(cs)后面的代码中的值JS
<head runat="server">
<title></title>
<script>
function foo() {
var values = ["1,", "2", "3"];
// Make the ajax call
$.ajax({
type: "POST",
url: "Default.aspx/Done", // the method we are calling
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ arr: values }),
dataType: "json",
success: function (result) {
alert('Yay! It worked!');
},
error: function (result) {
alert('Oh no :(');
}
});
return false;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" UseSubmitBehavior="false" OnClientClick="return foo();" />
</div>
</form>
</body>

public static void done(string[] ids)

String[] a = ids;
// Do whatever processing you want

至少有一个问题是您的网址是“Default.aspx / Done”,但该方法似乎位于WebForm3.aspx / Done上。 您的代码实际发生了什么?这是错误的吗?

首先,aspx的按钮是将你的aspx表单发送到回发,这样你就需要像这样更改aspx
<script>
function foo() {
var values = ["1,", "2", "3"];
// Make the ajax call
$.ajax({
type: "POST",
url: "Default.aspx/Done", // the method we are calling
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ arr: values }),
dataType: "json",
success: function (result) {
alert('Yay! It worked!');
},
error: function (result) {
alert('Oh no :(');
}
});
return false;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" UseSubmitBehavior="false" OnClientClick="return foo();" />
</div>
</form>
</body>
foo方法返回false的原因是你不想让你的按钮开始回发。我还添加了另一个属性UseSubmitBehavior =&#34; false&#34;保证它。
脚本部分我将值对象更改为实数数组,然后在发送数据时,我将其转换为json,其中包含值对象。这段代码可以在您的示例中正常使用
修改:对于我的测试中的工作版
aspx页面(修剪主页的详细信息)
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<script>
function test() {
var values = ["1,", "2", "3"];
// Make the ajax call
$.ajax({
type: "POST",
url: "Default.aspx/test", // the method we are calling
contentType: "application/json; charset=utf-8",
data: JSON.stringify({ arr: values }),
dataType: "json",
success: function (result) {
debugger;
alert('Yay! It worked!');
},
error: function (result) {
alert('Oh no :(');
}
});
return false;
}
</script>
<asp:Button ID="Button3" UseSubmitBehavior="false" OnClientClick="return test();" runat="server" Text="Deneme" />
</asp:Content>
RouteConfig和原始方法
public static class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
var settings = new FriendlyUrlSettings();
//settings.AutoRedirectMode = RedirectMode.Permanent;
routes.EnableFriendlyUrls(settings);
}
}
[WebMethod]
public static void test(string[] arr)
{
}
