我试图在jsp中的按钮单击事件上调用javascript函数中动作类中的方法。我正在使用struts 2.你能告诉我怎么做吗？ListAlgorithmAction 类中有一个函数，我想在用户单击提交按钮时调用它。
function alertselected (){
var x = document.getElementById ( "select_name" ).selectedIndex;
var y = document.getElementById ( "select_name" ).options;
var id = y [x].index;
redirect(id);
}
function redirect(x){
document.getElementById ( "param_ID" ).value = x;
document.forms ["./ListAlgorithmAction"].submit ();
}

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.
我认为这与 Struts2 无关，因为 struts2 独立于您调用操作类的方式，无论是通过 java 脚本表单提交、ajax 还是通过简单的表单提交。
i believe you have some form in your jsp like
我相信你的jsp中有某种形式
<s:form action="myAction" name="myForm">
some data
</s:form>
on click you can do something like
点击你可以做类似的事情
function redirect(x){
document.getElementById("param_ID").value=x;
document.myForm.action="ListAlgorithmAction";
document.myForm.submit();
}
This is just solution based on your inputs and there can be many more if you able to define your problem more
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，那么可能还有更多

For similar implementations we used to use http://directwebremoting.org/dwr/index.html(DWR). You can try that.. if you have big implementation i would suggest you to integrate this framework
对于类似的实现，我们曾经使用http://directwebremoting.org/dwr/index.html(DWR)。你可以试试..如果你有很大的实现，我建议你集成这个框架
