    redirect(id);
}

function redirect(x){
    document.getElementById ( "param_ID" ).value = x;
    document.forms ["./ListAlgorithmAction"].submit ();

推荐答案

我不认为这与 Struts2 相关，因为 struts2 独立于您调用 action class 的方式，无论是通过 java-script form submit、ajax 还是通过简单的表单提交.

I do not think this is something related to Struts2 ,since struts2 is independent of the way you call action class be it by java-script form submit,ajax or by simple form submit.

我相信你的jsp中有某种形式

i believe you have some form in your jsp like

<s:form action="myAction" name="myForm">
  some data

</s:form>

点击你可以做类似的事情

on click you can do something like

function redirect(x){
    document.getElementById("param_ID").value=x;
    document.myForm.action="ListAlgorithmAction";
     document.myForm.submit();
    }

这只是基于您的输入的解决方案，如果您能够更多地定义您的问题，可能还有更多

This is just solution based on your inputs and there can be many more if you able to define your problem more
