嘿家伙我正在尝试使用drawString()函数从数组中的搜索中绘制结果.我正在使用下面的代码

import java.awt.Graphics;

public class canvas extends JPanel{
    int i, count;
    public String read_string = "";
    public String[] names = {"Duncan","Matthew","Kevin","Etc"};
    public String[] searchfor = {"Duncan","Kevin"};
    public canvas() {

    search();


    }

    public void search() {

        for(i=0; i<names.length; i++) {
            read_string = names[i];
            if(read_string.contains("Duncan") || read_string.contains("Kevin")) {

                count++;

                System.out.println(read_string);
                drawThatText(null, read_string, 500*i + 1, 500*i + 1);
            } else {

            }


        }
    }


    public void drawThatText(Graphics g, String s, int x, int y) {


        g.drawString(s, x, y);

    }
}

我收到以下错误

Duncan …

嗨,我有以下代码:

<a onclick="show_login()">Login
<span id="login" style="visibility: hidden">
<form method="post" action="login.php"> 
<label for="username">Username:</label>
<input type="text" name="username" /></a>
<label for="password">Password:</label>
<input type="password" name="password" />

<input type="submit" name="login" value="Login" />
</form>
</span>

我想知道如何使用函数名称"show_login"隐藏/显示该跨度.我该怎么做呢？
