I am not very fond of Javascript as it is not documented properly and it is some sort of pseudo programming language.....

Maybe someone of you has an idea......

I am trying to display the picture description to every user picture inside of a div tag.

If someone clicks through the pictures with the previous and next button, I want to hide all div tags but the one that corresponds to the selected one.

The drop down list displays the number of the images....

This number is also used for naming the div tags.

But how do you reference variable names that are generated dynamically?

The layer is called desc+number = desc0, desc1, desc2....depending on how many user pictures there are.

I am not sure whether you use the window method for that or not....

i know nothing about this, but i think you are AMAZINGLY smart for all what you done

It is maybe a general problem/question.

You have variables that you can use in javascript in order to access the components such as a combobox in order to fire up some events when something happens or in order to find out which selection has been made.

When you click through the pictures on someones profile with the previous and next button, or if you use the combobox to directly jump to a particular picture, a javascript method is called that will replace the image with the selected one.

Now, I want to additionally, not only swap the user picture, but also display some additional text.

In order to do that I print all texts already at the beginning, but I just make them invisible. All those texts are surrounded by <div> tags and have an id - which are called desc0..desc{number of the last picture}.

So all the text is already on the page, but made invisible.

When someone now selects picture 2, the text for picture 2 should be displayed....this means all div elements need to stay invisible and the attribute of the correct div elements needs to be made visible.

If you then select picture 3, all <div> elements apart from desc3 need to be made invisible.

As the number of pictures are dynamic, the javascript needs to dynamically hide and show the div elements.

The name of the div elements can be built inside the javascript method it is just the "desc" string appended with the number of the image.

However, then you only have a string - but I need a reference to the component with that id....so basically it you receive a simple "String" that is the name of the method you want to call.

In real java you would do something like class.forName("com.my.funny.class"), and then you could call a method on it.

I dont know who to do that in Javascript though....it is not even a real class....
