jsp搜索只支持当前页面搜索如存在翻页功能请使用java
以页面列表为例:
1.在列表页单条记录外套一层div;div name="searchName" search="J2联赛北九州金泽塞维"/div
search为自定义属性 value为可搜索的关键字
2.js
$("[name='searchName']").each(function(){
var n = $(this).attr("search");
if(n.indexOf(name) == -1 )
{
$(this).hide();//隐藏不存在关键字的列表
}

textfile.setBounds(1, 1, 100,20);
button.setBounds(1, 25, 80,80);
this.add(button);
this.add(textfile);
button.addActionListener(this);//添加事件监听
this.setVisible(true);
}
public static void main(String[] args) {

//这个rs集合当中就是想要的数据
} catch (ClassNotFoundException e1) {

} catch (SQLException e2) {
// TODO Auto-generated catch block
