我不太熟悉jspservlet。当点击这个“添加”按钮时，它会将这些值发送到检查表中，并且在点击“完成”按钮后，这些被检查的项目会显示在另一个页面上。任何帮助都将不胜感激

我尝试了以下代码

这是我的handle.jsp代码

<body>

<div id="myDIV" class="header">
        <form action = "Handle_servlet" method = "POST">
        <div class = "hd" >
            <h2 style="margin:10px;float:center;text-align:left;">INCOMING CALLS</h2>
                <input type="text" id="myInput" placeholder="Call ID...">

                    <select class="input100" name="iname" id="myInput1" >

为什么要使用检查表的选项按钮，应该使用复选框。提交表单后，您应该在servlet中检索值

我在做一个项目，你要求我做的也是一样

Index.jsp

用户检查其公司的所有实力，然后单击提交

 <form action="swot" method="post">
    <div class="strength" style="border: 3px solid crimson ; ">
        <div class="panelhead">
        <center>   <h3>Strength</h3></center>
        </div>
    //give value property according to your needs.
        <p><input type="checkbox" name="strength" value="10"/>Brand Name</p>
        <p><input type="checkbox" name="strength" value="8"/>Customer Loyalty</p>
        <p><input type="checkbox" name="strength" value="9"/>Technology</p>
        <p><input type="checkbox" name="strength" value="9"/>Unique Products</p>
        <p><input type="checkbox" name="strength" value="7"/>Supply Chain</p>
        <p><input type="checkbox" name="strength" value="8"/>Innovative Culture</p>
        <p><input type="checkbox" name="strength" value="7"/>Cost Advantages</p>
        <p><input type="checkbox" name="strength" value="6"/>Size Advantages</p>
        <p><input type="checkbox" name="strength" value="8"/>Financial Leverage</p>
        <p><input type="checkbox" name="strength" value="9"/>Economics of Scale</p>

    </div>
            <center><input class="submit" type="submit" value="Submit"/></center>
    </form>

现在，所有值都存储在数组强度中。如果value属性包含integer，则需要对其进行类型转换

   int[] mat = new int[strength.length];

    for(int i = 0; i < strength.length; i++)
    {
        mat[i] = Integer.parseInt(strength[i]);

    }

int[]mat=新的int[strength.length]；
对于（int i=0；i


快乐编码。退房。
public class swot extends HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        PrintWriter out=response.getWriter();


        String strength[]= request.getParameterValues("strength");

   int[] mat = new int[strength.length];

    for(int i = 0; i < strength.length; i++)
    {
        mat[i] = Integer.parseInt(strength[i]);

    }
