将选定的单选按钮值添加到Struts2 Action类中

Question

我从单选按钮到JavaScript获取问题和所选答案的值，并将这些值存储在两个数组中。我需要将这两个数组传递给struts2动作类并存储。

JavaScript代码：

<script type="text/javascript">
     var nameArry = [];
     var i=0;
     var count=[];
    function handler(_this) {  


                var qno_name=_this.name;
                var id=qno_name.substring(1);

                  var qid=$("#id"+id).val();
                  //alert("qid"+qid)

        var ans=_this.value;
        nameArry[i]=ans;
                // alert(ans);   
                  // alert(nameArry[i]);



            count[i]=qid;
        i=i+1;
        /* document.write(nameArry);
        alert(nameArry); */
        //  
    }

  </script>

JSP代码：

 <table id="employeelist" class="table table-striped table-bordered table-hover">

                                <tr>
                                    <th>SL.No</th>
                                    <th>Question</th>
                                    <th>QID</th>
                                    <th>Very Little Like Me</th>
                                    <th>A Little Like Me</th>
                                    <th>Like Me</th>
                                    <th>A Lot Like Me</th>


                                </tr>

                                <tbody>

Answer 1

我用复选框尝试了同样的事情，我希望它也适用于单选按钮。

首先，您需要在具有getter和setter的Action类上创建实例 HttpServletRequest 请求。现在在你的视图页面（jsp或html）中给你的radiobutton一个名字，比如myRadioButtons。

现在在行动课上， String [] checkedBoxes = request.getParameterValues（＆＃34; myRadioButtons＆＃34;）;

现在在上面的数组中你应该获得1和0的值数组。
