I am making a online movie tickets booking website and in my index page I have 5 drop down boxes movies, timings, theatre name, date and price. All these drop down boxes use 2 sql tables.
What I need is that the drop down boxes get populated from the databse based on each others value. For eg. the movie name to be populated from database and then the show timing and theatre name based on the movie name.

Please help me as I have searched a lot regarding this but all in vein. It is urgent as I need to submit my project in 10 days.

Thanks in advance.

I will send the code for sure in the evening..Right now I am not having the code. But till then at least you can give me the idea of how it can be done?

This "dynamic population", as you call it, would happen on the client side, but JSP, of course, runs on the server side, so you have three options

1. Send all of the data (either in the form of hidden fields or prepopulated JavaScript Arrays) and use JavaScript to replace the contents of one depending on the selection in the other.

2. Use AJAX to request a list of values from the server and update the second list whenever a value is chosen in the first.

3. Submit the form to populate the second list whenever a value is chosen in the first list.

Unfortunately, not in the way he wishes. He wishes to have the user be able to select an option in one list, and from that, populate the options in the second list.

So, he can use those on the third option. I.E. when the user selects a value in the first drop down, the form gets submitted (probably to some alternate url, or the original must check whether the second list has a selected value or not), then he can use the JSTL query tags to populate the second list. But, JSTL does not help on the client-side. JSTL tags are used server-side. I.E. They are evaluated on the server in order to produce HTML.

Actually, he might use them in all of the options, the only question is when and how. In the first option, in order to find all possible values, and the second option in the page that the AJAX call refers to.

aijade thanx for ur comment. I dn't know ajax and ajax is not to be used in my project..I need to use only jsp and javascripts to do teh same. Can you please tell me from where can I get the javascri[t example so that I could apply the same in my project as I dn't have good knwledga of javascripts.

You sure you no supposed to use AJAX? In case you do not know AJAX stands for Asynchronous JavaScript and XML, basically enhanced JavaScript...

By asking on a JavaScript forum, maybe?

People here, however, due to the terms and conditions for this site, are not supossed to just "give it to you", though.

And Peter is correct. AJAX is JavaScript, it just has comes as a buch of "prepackaged" functions and utilities.

As I told earlier I want to populate the value in the second drop down box according to values in first drop down box. The first drop down box is populated from the database. I am posting the code which I tried, but it doesn't work. The second drop down box is not populated with any value. I dn't understand how to do. Please help.

The taglib directive below imports the JSTL library. If you uncomment it,
you must also add the JSTL library to the project. The Add Library... action
on Libraries node in Projects view can be used to add the JSTL 1.1 library.
