我有这个脚本，基本上有 4 个选择框，我想要的是对于 2 个顶部选择框，他将选择的选项值提交给一个动作（可以在“ProductKoppeling/ProductKoppelingPartial”找到），我想让当我单击一个选项但没有刷新页面时，他会提交此数据。

我尝试了 JSON 并尝试了 Ajax，但我没有让它工作。我应该怎么做？

脚本：

<script language="javascript" type="text/javascript">
function delete_1() {
    var answer = confirm("U staat op het punt dit product te verwijderen, wilt u doorgaan?")
    if (answer) {
        document.getElementById('Actie_1').value = '5';
        document.getElementById('hpg_submit').submit();
    }
}
function delete_2() {
    var answer = confirm("U staat op het punt dit product te verwijderen, wilt u doorgaan?")
    if (answer) {
        document.getElementById('Actie_2').value = '6';
        document.getElementById('pg_submit').submit();
    }
}
function delete_3() {
    var answer = confirm("U staat op het punt dit product te verwijderen, wilt u doorgaan?")
    if (answer) {
        document.getElementById('Actie_3').value = '6';
        document.getElementById('p_submit').submit();
    }
}
</script>

CSHTML：

您正在使用 Html 表单。

默认情况下，这会导致刷新。

使用 ajax 表单或根本不使用表单，只调用一个操作但不返回操作结果。

创建一个类似于以下内容的控制器：

public void Action(String paramater)
{
    ...
}

当您从视图中调用它时，它将在服务器端执行代码，而不会对客户端造成任何影响。

按照要求：

添加了非刷新 Ajax 表单示例：

$.ajax({
  type: "POST",
  url: "URL",
  data: dataString,
  success: function() {
    ...
    };
});
return false;

return false 防止刷新。

也许您应该使用 Ajax 调用...并选择您希望刷新的 div：这是一个简短的示例：

AjaxOptions ajaxOptions = new AjaxOptions
{
    HttpMethod = "Post",
    UpdateTargetId = "Mydiv",
    OnSuccess = "aJqueryFunction"
};


在你的 ajax 调用中：

<div id="Mydiv">
   @using (Ajax.BeginForm("text", "Action",(optional)"Cotroller", ajaxOptions))
{}
</div>
