Dynamic message

Hi,

Hi,

In the code below,

Row1 of the table has a drop down menu
In row2 I need to display an appropriate msg depending on the choice the user made in row1.

Could you please advise me on the best way to go about it.

Any sample code would be very very helpful.

The code below is just a subsection of the actual jsp page, thus I need to be able to do this without going to the servlet.

THE JAVASCRIPT

THE RELEVEANT HTML

The obove doesnt seem to work and gives me an error " 'result' object not found. "...

Thanks in advance for all the help

dynamic msg display

Hi,

In the code below,

Row1 of the table has a drop down menu
In row2 I need to display an appropriate msg depending on the choice the user made in row1.

Could you please advise me on the best way to go about it.

Any sample code would be very very helpful.

Example:

If the user chooses 90 then row2 should have in it 'A+' but if the user chooses 80 then 'A' and so on.

The code below is just a subsection of the actual jsp page, thus I need to be able to do this without going to the servlet.

Any kind of help will be appreciated

THanks a LOT in advance

Dynamic content for drop downs

Thanks for all your suggestions.

I would like to have all the information on the ONE webpage so that the action class doesn't need to called again n again. This seems possible only if all the data is already stored in 'javascript' variables.

I can get the information from the action class and display it onto the webpage, but how can I pass this information (arraylists consists of available options) into a 'javascript' function and initialize the variables?

Any help on this will be very very appreciated.

Thanks a bunch

Dynamic content for drop downs

Hi,

In a struts project I have to create ONE web page with around 5-6 drop downs. The content of one drop down depends on the value selected in the previous one.

e.g

drop down 1 : UK (selected)
FRANCE

drop down 2 : LONDON
LEEDS

BUT if

drop down 1 : UK
FRANCE (selected)

drop down 2 : PARIS
NICE

Can any one tell me I can achieve this.

Thanks for the all the help in advance

Java in General

Hi,

In the following piece of code I am trying to select in the dropdown box the "buId" when equal to the "bu" set in the form and add the other "buchoices" to the drop down list.

"buchoices" has been initialised to {"Abc", "def", "ghi"} in the action class using the set method from the form. And "bu" has been set to "Abc" in the similar manner.

I am failing on 2 counts
1. selecting the value in the drop down when buId == bu
2. showing the rest of the list on the webpage to the user

(timeDetails is the name of the form bean which has has been declared using the usebean tag.)

Any help on how i can do this will be greatly appreciated.

Thanks a bunch

Cookies and Struts

Hi

My application starts of with an index.jsp page where the user inputs his name and email address, this call an action 'createCookie' where the details are stored in a cookie.

I need the details to be read from the cookie and displayed to the user the next time he opens the webpage.

The relevant code int index.jsp

The revelant code in createCookie.java

The code in bold italics in index.jsp in the text input box is where I am getting the error. If any one could point me the right way to do this, it will be great.

The error I get is "attribute nameCookie has no value", even though the line above that prints out the value of the nameCookie.

Thanks a bunch
