JSP中未結束的字符串文字錯誤？

Question

我想動態更新gridview中按鈕的值到計數值。現在，我在「out.println("<td>" + "<input type = button id = getid onclick=getbuttonid() value = "<%=count%>" + ">" + "</td>");我的目標是計數的值分配作爲按鍵值獲取未閉合的字符串文字錯誤。我到底做錯了什麼？

 <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

變化

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>");

正如我在我的answer中寫到你的其他問題一樣，不要用Java代碼來生成HTML輸出，正如你所看到的，它是很容易出錯。

無論如何，如果你堅持，那麼使用

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