Java 在Struts 2中使用jQuery的Ajax表单提交按钮

我有一个带有提交按钮的表单，当点击该按钮时，它将转发到下一页并从后端获取所有数据。但是基于新的需求，页面需要保持相同的页面，但是后端流应该是相同的。所以我用Ajax调用按钮来获取后端数据。但它并没有像预期的那样工作。请检查下面的代码

我正在尝试运行该页面

jQuery代码：

上面的代码没有调用action类中的

list（）

方法。

试试这个脚本

<script type="text/JavaScript">
  $("#searchForm").submit(function(event) {
    event.preventDefault();
    var $form = $(this);
    var url = $form.attr('action');
    $.post(url).done(function(data) {
      alert(data);
    });
  });
</script>

试试这个脚本

<script type="text/JavaScript">
  $("#searchForm").submit(function(event) {
    event.preventDefault();
    var $form = $(this);
    var url = $form.attr('action');
    $.post(url).done(function(data) {
      alert(data);
    });
  });
</script>

有人知道这个问题吗？几句话：url看起来不对。除了在jQuery代码中添加一个错误处理程序外，它应该像“/product/save”。这样做你就会知道发生了什么。我真的不明白你在问什么：/请花5分钟来提高你问题的英语部分（代码似乎很好）。我不认为这是做这个请求的正确方法。你能检查一下struts ajax标记和/或struts2 jquery插件吗。有人知道这个问题吗？几句话：url看起来是错误的。相反，它应该像“/product/save”，并且在你的jquery代码中添加一个错误处理程序。这样做你就会知道发生了什么。我真的不明白了解你的问题：/请花5分钟来提高你问题的英语部分（代码似乎很好）。我认为这不是正确的方法。你能检查struts ajax标记和/或struts2 jquery插件吗。需要什么类型的按钮？比如或者因为你提到了form.attr（'action'））。这不要紧，任何一个都不要紧。表单是它上面的另一个标记。它不会触发方法…注意：Struts带有codebehind插件。我正在尝试在页面加载时自动单击按钮。单击按钮时，它会给我错误“org.apache.struts2.dispatcher.dispatcher-找不到操作或结果”.由于此codebehind插件，所以操作必须是product！list。.希望这就是原因。按钮的类型需要是什么形式的？就像或因为您提到了form.attr（'action'））。这不要紧，任何一个都不要紧。表单是它上面的另一个标记。它不会触发方法…注意：Struts带有codebehind插件。我正在尝试在页面加载时自动单击按钮。单击按钮时，它会给我错误“org.apache.struts2.dispatcher.dispatcher-找不到操作或结果”.由于此代码隐藏插件，所以操作必须是product！list..希望这就是原因。
