❶ java web 怎么在jtable中添加按钮

java web在jtable中添加按钮的示例如下：

importjava.awt.BorderLayout;
importjava.awt.Color;
importjava.awt.Component;
importjava.awt.Dimension;
importjava.awt.event.MouseAdapter;
importjava.awt.event.MouseEvent;
importjava.io.File;

importjavax.swing.BorderFactory;
importjavax.swing.ImageIcon;
importjavax.swing.JButton;
importjavax.swing.JFrame;
importjavax.swing.JPanel;
importjavax.swing.JScrollPane;
importjavax.swing.JTable;
importjavax.swing.UIManager;
importjavax.swing.border.Border;
importjavax.swing.border.EmptyBorder;
importjavax.swing.table.AbstractTableModel;
importjavax.swing.table.TableCellRenderer;

{
privateJTabletable;

+"images"+File.separator;

publicJTableButton(){
setBorder(BorderFactory.createLineBorder(Color.red,1));
init();
}

privatevoidinit(){
StringheadName[]={"Name","age","sex","adress","image"};

buttons=newJButton[5];
for(inti=0;i<buttons.length;i++){
buttons[i]=newJButton(""+i);
}
Objectobj[][]={
{"LiMing",23,Boolean.TRUE,buttons[0],
newImageIcon(path+"icon.png")},
{"ZhangSan",25,Boolean.TRUE,buttons[1],
newImageIcon(path+"icon.png")},

{"LiSi",28,Boolean.TRUE,buttons[3],
newImageIcon(path+"icon.png")},

}

//添加事件

System.out.println("row="+row+":"+"column="+column);
if(column==3){
//处理button事件写在这里...
System.out.println(((JButton)table.getValueAt(row,column)).getText());
}
}
});
}
publicstaticvoidmain(String[]args){

}
{

privateObjectobj[][];

publicMyTableModel(){
super();
}

publicMyTableModel(String[]headName,Object[][]obj){
this();
this.headName=headName;
this.obj=obj;
}

publicintgetColumnCount(){
returnheadName.length;
}

publicintgetRowCount(){
returnobj.length;
}

publicObjectgetValueAt(intr,intc){
returnobj[r][c];
}

publicStringgetColumnName(intc){
returnheadName[c];
}

publicClass<?>getColumnClass(intcolumnIndex){
returnobj[0][columnIndex].getClass();
}

@Override
publicbooleanisCellEditable(introwIndex,intcolumnIndex){
if(columnIndex==3||columnIndex==4){
returnfalse;
}
returntrue;
}

}
}

{

}

}

❷ javaweb鼠标移到内容上自动出现一个小界面

1、给目标javaweb绑定onmouseover，onmouseout事件，弹出一个窗口用div+背景图片的方法，自己控制样式。
2、当鼠标放在.navli上时，把subpage内的li全部隐藏，然后再把相应id的li显示出来就行了，就不会出现一个小界面了。
