Question

我正在尝试将gridview中按钮的值动态更新为计数值。现在，我在“out.println("<td>" + "<input type = button id = getid onclick=getbuttonid() value = "<%=count%>" + ">" + "</td>");处获得Unclosed String文字错误。我的目标是将count的值指定为按钮值。我做错了什么？

      <tr>
                <td colspan=4 align="center"
                    style="background-color:teal">
                    <b>User Record</b></td>
            </tr>
            <tr style="background-color:lightgrey;">
                <td><b>Record Number: </b></td>
                <td><b>Card Number: </b></td>
                <td><b>MiddleName:</b></td>
                <td><b>BankAccountID:</b></td>
                <td><b>CurrencyID:</b></td>
                <td><b>DayTransactionLimit:</b></td>
                <td><b>Select:</b></td>


</tr>
  <%
      if(request.getParameter("mobilenumber")!=null)
              {
 FileReader fr = new FileReader(new File(("C:\\Users\\Farheen\\Documents\\NetBeansProjects\\Demo\\records.txt")));
  BufferedReader br = new BufferedReader(fr);
  String line = null;
  int count =0;
//  out.println("<table>");

  while((line = br.readLine()) != null){
    //out.print(line + "<br/>");
      out.println("<tr>");

    String[] data = line.split("\t");
    for (String val : data) {

        out.println("<td>" + val + "</td>");

        count ++;

  }
           out.println("<td>" + "<input type = button id = getid onclick=getbuttonid() value =  "<%=count%>" + ">" + "</td>");

   out.println("</tr>" );

  }
//    out.println("");
  br.close();




            }
%>

Answer 1

正如我在answer中写到的另一个问题，不要使用Java代码生成HTML输出。正如您所看到的，非常容易出错。

无论如何，如果你坚持，那就用

out.println("<td><input type =\"button\" id=\"getid\" onclick=\"getbuttonid()\" value=\"" + count + "\"></td>");

Answer 2

更改

out.println("<td>" + "<input type = button id = getid onclick=getbuttonid() value =  "<%=count%>" + ">" + "</td>");

到

out.println("<td>" + "<input type = button id = getid onclick=getbuttonid() value = "+ "<%=count%>" + ">" + "</td>");
