Determine which button is clicked
I am creating the download buttons on my page dynamically and I am assigning the name also dynamically attaching the counter with the name. Now On form post, i want to know which button( button at which counter ) was being pressed. Could u help me on this.
Use request.getParameterNames( ) to get an enumeration of all the names passed by the form. You can then go through the list and determine which button was pressed since the name of that button would be passed along.
If you are uncomfortable with using the enumeration technique, do a request.getParameter( button_name ) for each button and check whether you get a null value which implies the button wasn't pressed, or the counter value, which implies the button was pressed. If you have a lot of buttons, this results in some redundant code, but if you have only one or three, then this is probably an ok way to do it.

How can I determine which image was clicked in 3D carousel?
I have been modifying some 3D carousel code that I found in hopes that I can get it such that when image "resolv2.jpg" (or any of my other images) is clicked on at the front of my carousel, it goes to a specific webpage. By just replacing "moveBack(event.target) from the toggler section of the code with "navigateToURL:(newURLRequest('http://google.com'), the target DOES sucessfully go to google when clicked on. However, I want to modify this code by altering the else statement to say something to the effect of "else if event.target (clicked on object) is 'resolv2.jpg' THEN go to google". So essentially, my question is how can I determine which image was clicked? Here is the entire code with the area I was altering bolded:

How to identify which button is clicked in an action
Hi,
I am just checking whether it is possible to build calculator or not in webdynpro for abap.
I have some buttons and i have associated same action for all the buttons and in that action i would like to know which button is clicked.
Please let me know the code for that
Thanks
Bala DuvvuriHi Bala,
Its possible. Just go to the action handler for the button & read the attribute ID of the WDEVENT which is passed by the framework. This id will contain the id of the button which triggered the event. Consider the code fragment below:
method ONACTIONACTION .
DATA: lv_button_name type string.
lv_button_name = wdevent->get_string( name = 'ID' ).
endmethod.
At the end of execution lv_button_name will have the ID of the button which triggered the event.
Regards,
Uday -
hello,
I have a an array of buttons, which has 20 buttons.
How can I know which button is clicked inside actionPerformed method.
THANKS
Chamal.Search for the Java Tutorial and carefully read the section on event listeners. You can find lots of sample code there.
Basically, you can branch on action commands (typically the label on the button) or event sources (a reference to the object which fired the event). The second method is preferrable to the first, particularly with regard to internationalized applications. -
How can I find which button is clicked?
I have two buttons on my page.Is there any way so that I can find which button is clicked in my JSP page?I do not know javascript I tried to pass a parameter by url rewriting through a Javascript function to another page.
But it did not work? how can I do this?
Can I return a parameter from javascript to a JSP page?
Plz help me
Thanks in advance
Amit VarshneyIf you give the submit button a "name" attribute, the name of the button you pushed will come through as a parameter, along with its "value" (the text on the button)
ie
// in your jsp page
<input type='submit' name='button1' value='FromB1'>
<input type='submit' name='button2' value='FromB2'>
// in your servlet code...
boolean b1Pressed = request.getParameter("button1") != null;
boolean b2Pressed = request.getParameter("button2") != null; -
How to determine wich button is clicked?
... and so on. If you have the time the whole thing is
downloadable
here.. Greetings
from Sweden. Here's some of the code...that is very easy to do that.
First u assign a separate variable for each button (or) keep
an array where its length is total no of buttons instead of
variables.Store 0 as values for all buttons.
When one button is clicked make the index for that button to
1 and if another button is clicked make the index for that button
to 1 and remaining values to 0.
So,write a function to check the values in array and if 1 is
there change the color of that button to grey and other buttons to
black.
Try this and tell me whether it works or not. -
Trying to get a movie clip to go both up and down depending on which button gets clicked
hello,
I have a file with 5 movie clips in it. I have a button that when clicks, plays each one. One of the movie clips needs to move both up and down and I am having a lot of trouble with this.
stop();
function showVenue(Event:MouseEvent):void
mc_speaker.play();
function showSpeaker(Event:MouseEvent):void
mc_compliance.play();
function showCompliance(Event:MouseEvent):void
mc_strategic.play();
mc_data.play();
function showStrategic(Event:MouseEvent):void
mc_data.gotoAndPlay("down");
function showData(Event:MouseEvent):void
mc_data.gotoAndPlay("up");
btn_viewMore_Venue.addEventListener(MouseEvent.CLICK, showVenue);
btn_viewMore_Speaker.addEventListener(MouseEvent.CLICK, showSpeaker);
btn_viewMore_Complinace.addEventListener(MouseEvent.CLICK, showCompliance);
btn_viewMore_Strategic.addEventListener(MouseEvent.CLICK, showStrategic);
btn_viewMore_Data.addEventListener(MouseEvent.CLICK, showData);
Is there anyway to attach my file here for someone to look at???
thanks!
babsWell, on the mc_data movie clip, I had the animation going up and down with stop actions to stop it. so I put labels on those areas and tried to just control it that way. Seemed simple enough, but not working.
I really don't know how to control the toggle up and down in AS without using the timeline....just trying to help a friend, and ready to scream..I thought this would be so simple...
would be easier to explain if I could show you a dummy file...but I still don't see an attach button???? -
Knowing which button is clicked
i have code that creates button objects ,stores them in array

mybutton=new Button();
mybutton.x=10;
mybutton.y=10+50*i;

Which row was clicked in an SQL Query (updateable report)?
I have an application with a report based on an SQL Query (PL/SQL function ...) defined on the Global Page.
On the pages where the report is used, I want to click in a particular column (TCKT_ID) and pass the values in that row to another page for processing.
Things I would like to know:
1) How to determine which row was clicked? The column is TCKT_ID and it is used as a link to another page. The SQLis a non-trivial (for me!) join of tables.
2) How to refer to the values of the other columns in that row? Because I format with "div," the columns are named -- no "f02", "f03", etc.
3) How to pass multiple values (ENAME, JOB, MGR, SAL, COMM) to the target page? You might ask: Why not just re-query for the data using a unique key. Splendid idea, but the unique key is four columns so I still need some way to pass these four values to have that unique key.
I've constructed a "pretty close" example of the situation here:
WS APEX_EXAMPLES_01
demo / demo
Application: Row Info 10782 - Page 0 has the report. Page 1 displays it with a link (in red) to page 2.
I think I can complete most of what I need if someone can just show me how to get, say, the ENAME of the row clicked on page 1, so I can use it to filter the query on page 2 to just this row clicked on page 1.
Using <tt> </tt>, I tried to display the actual row from View -- Source of the real report I'm dealing with but it just comes out like this

ARS003_TESTNBDI wonder if I'm not understanding something. This seems like a very simple thing to do without any "tricks"
Take a look, I've modified the LINKING_NUMBER column on the p0 report.
Basically, you just specify the fields you want to populate and their assignments. I added 4 destination fields on p2 to receive the assignments. Then you can do anything you want with them like modifying a report, etc...
The only trick here is that in order to pass more than 3 items in the URL you need to change your link type from Page in this application to URL. Then you can specify lost of items this way.

Making a text field required when a radio button is clicked
Hello all, I am very new to designing PDF forms, and I want to implement this requirement but have no idea how to go about doing it. I am designing an order form, and in a few different sections of the form are text fields that I want to be required, but only if a certain radio button on the form is clicked. So for example, I have a radio button group on the page consisting of two buttons, and then immediately to the right is a text field. If the user selects button 1, the text field is not required, but if they select button two, the text field is required. How do I implement this? I am using Livecycle ES3. And when I say required, I am referring to the field value/property of "User Entered - Required". Also, I cannot accomplish this by hiding and unhiding the field depending on which button is clicked, as this form will also be printed and filled out by hand, so all fields must be visible at all times. This form does have a submit by e-mail button and that is how it will be used primarily.
Also, I have searched around the forums a bit, and have tried some Javascript I have found, tying it to a mouseup event on the radio button, for example "getField("Text1").required = (getField("Radio1").value == "Yes");" and "getField("Text1").required = true;" with the names changed for my fields, but no matter what I try it has no effect
Thanks!i hope this helps u.You can always optimize tht code a bit more , it's coded roughly but it works.

Servlet: How do I know which button was pushed?
Hi All,
I have a web page that has two buttons on it, one to log out and to other to retrieve items (HTML is below). I have a servlet that receives the HTTP Respone/Request and passes the Config and Request to an BasicHandlerManager class that will look to see which button was pushed and then perform an action based on the button that was pushed. Well, in the BasicHandlerManager class I do not know how to determine which button on the web page was pushed. How do I determine that? I've found that they 'if' and 'else if' that contains the "Logout" and "Retrieve" always executes the 'if' statement and never the 'else if'. When I swap the "Logout" and "Retrieve" that are in the 'if' 'else if' statement it will still execute the 'if' and not the 'else if'. So, how do I determine which of the 2 buttons was pushed on the web page?
Here's my HTML and some code from the BasicHandlerManager.
Thanks for your help.
HTML Code:
<INPUT TYPE="HIDDEN" NAME="requestID" VALUE="HOMEPAGE">
<INPUT TYPE="SUBMIT" NAME="Retrieve" VALUE="Retrieve">
<INPUT TYPE="SUBMIT" NAME="Logout" VALUE="Logout">
BasicHandlerManager Class:
BasicHandler handler = null;
if (request != null)
String strRequestID = request.getParameter("requestID");
if (strRequestID != null)
if (strRequestID.equals("LOGIN"))
handler = new AccountDelegate(config);
else if (strRequestID.equals("HOMEPAGE"))
if (request.getParameter("Logout").equals("Logout"))
handler = new Logout(config);
else if (request.getParameter("Retrieve").equals("Retrieve"))
handler = new ProductDelegate(config);
if (handler == null)
handler = new DefaultHandler(config);
} // end if (strRequestID != null)
} // end if (request != null)
[\code]First change your buttons so they have the same name
thus
<INPUT TYPE="HIDDEN" NAME="requestID" VALUE="HOMEPAGE">
<INPUT TYPE="SUBMIT" NAME="Retrieve" VALUE="Retrieve">
<INPUT TYPE="SUBMIT" NAME="Logout" VALUE="Logout">
becomes
<INPUT TYPE="HIDDEN" NAME="requestID" VALUE="HOMEPAGE">
<INPUT TYPE="SUBMIT" NAME="SUBMIT" VALUE="Retrieve">
<INPUT TYPE="SUBMIT" NAME="SUBMIT" VALUE="Logout">
Now in your servlet you will want something akin to the following.
public void performTask(
HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
String action = request.getParameter("SUBMIT") ;
if( "Retrieve".equals(action) ){
// Perform whatever operation needs to be done on Retrieve
else if( "Logout".equals(action) ){
// Perform whatever operation needs to be done on Logout
else {
// Perform whatever operation needs to be done if all else fails
}By giving your buttons different names, which seems like a really good idea at the outset, you give them different parameter names in the request which A) takes up more space in the request and B) means you have to check both parameters. These are essentially the same action (Submitting) so you use the Value to retrieve the action indicated by the button.

What's the best way to determine which row a user clicked on via a link?
Hello. Probably simple question, but my googleing is failing me. I have a table, with a column that is a command link. How can I determine which row the user clicked on? I need to take that value, and pass it to a different page to bind it for a different query. I was thinking of setting the result in a session bean? Or is there a better way?
Thanks!Hi,
You have two options:
1. (Complex) Have your ActionListener evaluate the event to get the source, then climb the component tree up to the table and get the current row data;
2. (Simple) Add a setPropertyActionListener to the link with value="#{var}" target="#{destination}" where var is the table's var attribute value and destination is your managed bean that required the clicked row.
