Question

我是rails的新手并试图在rails 4中实现一个灯箱。我的问题是如何在erb中编写以下代码？

<a href="#img1">
  <img src="some_img.jpg">
</a>

<a href="#_" class="lightbox" id="img1">
  <img src="some_img.jpg">
</a>

Answer 1

<%= link_to image_tag("some_img.jpg"), "#img1" %>

<%= link_to image_tag("some_img.jpg"), "#_", :class => "lightbox", :id => "img1" %>

Answer 2

package com.example.noti;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent; 
import android.app.Service;
import android.content.Context;
import android.content.Intent;
 // TODO Auto-generated method stub
if(intent==null||intent.getAction()==null)
    return;
String action=intent.getAction();
if(action.compareTo("hello")==0)
{
    Intent it= new Intent(getApplicationContext(),Constants.class);
    it.setAction("hello");

    PendingIntent pt=PendingIntent.getService(getApplicationContext(), 1, it, 0);


    Intent it1= new Intent(getApplicationContext(),Constants.class);
    it.setAction("hello1");
    PendingIntent pt1=PendingIntent.getService(getApplicationContext(), 2, it1, 0);

    Notification.Builder builder=new Notification.Builder(this)
    .setSmallIcon(R.drawable.ic_launcher)
    .setContentTitle(hello())
    .setContentText("inside")
    .addAction(R.drawable.pre,"",pt)
    .addAction(R.drawable.next,"",pt1);
    NotificationManager nm=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    nm.notify(1,builder.build());

    handleIntent(intent);
    //return super.onStartCommand(intent, flags, startId);

}
if(action.compareTo("hello1")==0)
{
    Intent it= new Intent(getApplicationContext(),Constants.class);
     it.setAction("hello");
    PendingIntent pt=PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);

    Notification.Builder builder=new Notification.Builder(this)
    .setSmallIcon(R.drawable.ic_launcher)
    .setContentTitle("Main")
    .setContentText("inside21")
    .addAction(R.drawable.pre,"",null)
    .addAction(R.drawable.next,"", pt);
    NotificationManager nm=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    nm.notify(2,builder.build());
}
}
