problem with nested:image tag

[Anirban Das]

Hi,
Iam using Struts 1.3.8. Basicaly Iam using a <nested:image> tag.

 
   
nested:image src="./images/UpArrow.gif" property="oderByAsc" value="Date And Time"
 

Iam trying to retrive the value of the attribute "value".

To do so Iam using

request.getParameter("oderByAsc")

Unforutnately I unable to retrive any value. Can someone please help me ?

Thanks for your help in advance.

Cheers

You have to handle an <html:image> tag differently than you would an <html:submit> tag because of the fact that it's an image rather than a button.

My suggestion is to declare the property oderByAsc as type org.apache.struts.util.ImageButtonBean. You can then tell whether the button has been clicked by calling the bean's isSelected() method.

Merill,
Thanks for your response. But Iam still a bit confused.

My requirement is to have multiple images with same property. However they should be sending different values at run time when the respective image is clicked.

Is it possible ? If so how I will retrive the values of the image that got submited.

Are you suggesting that I create multiple properties for each of those images and retrive it in my action class to perform required action ?


A small code example would be realy helpful.

Thank you once again.

Cheers

I'm not sure if it's possible or not. If it is, I don't know of a way to make it work that way.

That's exactly what I'm suggesting. Example:

public class MyActionForm extends ActionForm {
 
  private ImageButtonBean button1 = new ImageButtonBean();
  private ImageButtonBean button2 = new ImageButtonBean();
  private ImageButtonBean button3 = new ImageButtonBean();
 
  // getters and setters
}

In your actionClass:

if (myform.getButton1().isSelected()) { 
   // do something
} else if (myform.getButton2().isSelected()) { 
   // do something else
} else if (myform.getButton3().isSelected()) {
   // do something else
}

Since my last post, I did think of a way to do it with a single property with a different value for each button. You could declare a hidden field for the property and use the onclick event for each button to execute javaScript to set the property to a particular value. Example:

<html:hidden property="orderByAsc" />
<html:image src="./images/UpArrow.gif" property="dummy"
 onklick="this.form.orderByAsc.value = 'Date And Time';" />
<html:image src="./images/UpArrow.gif" property="dummy"
 onklick="this.form.orderByAsc.value = 'First Name';" />

Thank you Merill. Well actualy I implemented the second way most of the places. It works fine. I was wondering if there is a struts way of handling this issue and hence I posted that question. You showed me a way using the framework. I would try to implement the same.

Thanks once again.
