平移和缩放 jQuery Mobile 的图像

Question

我将不胜感激有关jquery移动Web应用程序的平移和缩放的任何帮助。我有一个建筑平面图的图像，顶部有一个图像地图，我希望用户能够从他的手机查看，放大和缩小并将感兴趣的区域平移到视图中。

Answer 1

这应该可以解决问题。 http://www.photoswipe.com/

Answer 2

我解决了OpenLayers的问题，图像现在可以平移和缩放 http://dev.openlayers.org/releases/OpenLayers-2.11/examples/image-layer.html

现在必须弄清楚如何将其与ImageMapster结合使用。(http://www.outsharked.com/imagemapster/(

Answer 3

我一直在研究同样的问题，即办公室的办公桌楼层地图应该根据办公桌的状态(空、已分配、热坐等(以不同的颜色显示。

除此之外，如果用户点击办公桌，应显示分配的员工/员工的详细信息。

上述要求是使用图像映射器 jquery 插件实现的。

还应提供缩放和平移。对于缩放和平移，我找到了最适合我要求的 gzoom 插件。但是，当与图像映射器插件一起使用时，它无法按预期工作。

感谢您对此的帮助。

我想

通了，从OpenLayers示例中获得了我需要的一切

。

我从服务器获取我的功能：

package actions;
import control_layer.Action;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

/** * * @author克里斯蒂娜 */公共类 GetFloorFeatures 实现操作 {

private static final int MAX_INACTIVE_INTERVAL = 900; // 15 minutes
private String view;
@Override
public boolean execute(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
    HttpSession session = req.getSession(true);
    System.out.println("------------ In GetFloorFeatures");
    session.setMaxInactiveInterval(MAX_INACTIVE_INTERVAL);
    view = "pages/maps/displayFloorFeatures.jsp";
    return true;
}
@Override
public String getView() {
    return view;
}
@Override
public Object getModel() {
    return null;
}

}

数据在 jsp 文件中被硬编码，但最终将由数据库查询生成：

<%@page contentType="application/json" pageEncoding="UTF-8"%>
<% response.setContentType("application/json");
//harcoded now, later will call database query to retrieve features for this floor
