                                        </form>

这是我的cshtml文件中的代码。我想使用ajax提交表单，以便每次用户提交任何内容时都不会刷新整个页面。

代码中还提供了运行表单所需的C＃代码。

任何帮助我如何使用ajax提交for？

谢谢！

Answer 1

使用Javascript或JQuery。例如。添加带有jquery代码文件链接的脚本标记，然后使用$ .get或$ .post进行ajax调用。

Answer 2

你应该删除

method="post"

从表单中提取完整页面。您还可以在Jquery文档中找到有关如何执行此操作的更多信息。

请参阅此链接的底部以获取示例：

使用此功能执行操作

            $.ajax
                ({
                    url: " URL",

                    data: "{ 'name' : 'DATA'}",

                    dataType: "json",

                    type: "POST",

                    contentType: "application/json; charset=utf-8",                   

                    async: true,

                    dataFilter: function (data) { return data; },

                    success: function (data) 
                    {
                        alert(data);
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {
                        alert("error");
                    }
                });
