Javascript: setting variables with selectable table issue

[matt larkin]

Hello everyone, I have had this problem for over a week and have not found a solution that will work the way I want it to.

using html I have created a selectable table, which I would like to send the index of the row to a servlet once it has been submitted.
example: if row 1 is selected then on submit the user is redirected to "productServlet?rowid="+row;

I want this variable to be set when a <tr onclick> is initiated, and changed accordingly if another row is clicked. the redirect to the servlet
also must be done in javascript as I have 3 different submit buttons that do 3 different things with the selected row. this part is sorted out
I have a function called setTarget(target) which redirects to the proper servlet depending on the value.

The problem is I am unable to get the onclick function variable in the setTarget(target) function. If I was to call a row(rowid) function inside setTarget then I would need the rowId in the first place so it wont work....

Please if anyone could help me or even point me in the right direction I would much appreciate it. I have spent 8+ hours trying to get this to work.

Sounds like you are making things much harder than they need to be. On the other hand, I can't really understand what you are trying to do.

Rather than a stream of consciousness -- please post the steps that you want the code to take on the click event.

Well The way my team has this interface set up you simply click from a selection of products in the selectable table.

Once a product is selected you may click the modify button, the show details button, or the delete button. in each of these cases
I have a redirect to a servlet which deals with the selected row accordingly. But for this to happen I cant simply redirect when someone
clicks a row as there are multiple options to choose from. This could be done easily with a listbox but formatting is not the same and
listboxes simply look like crap.

each row has a number associated to it(0,1,2,3) and when I redirect to the servlet I need to know which row was selected, either by setting the variable in a session which I dont think is possible, or send it in the url, but I dont kno how to get that variable into a url.

hopefully that explains it well enough

How?

Explain "multiple options".

well I set the value of the tr to the index value in my for loop which populates the table. as well I have the same list in my servlet so the referenced selection in my table matches the arraylist in my servlet.

As for multiple options I mean the 3 buttons to choose from, each goes to the same servlet but with different attribute values. If you read through my post you should understand what im trying to accomplish

<tr> elements do not have values. What do you mean by this? Maybe you should start to show some code (Please use code tags).

How does this prevent you from submitting a simple request as you stated earlier?

I'd re-evaluate your approach. Being snarky to people who are trying to help you because you are not explaining yourself well is not a winning strategy.

well mr Bear I solved my own problem finally. and as you have shown me, this site contains only incompetant programmers who cant understand a simple scenario. stackOverflow.com is where I shall go from now on, thank you for confirming my friends opinion on your forum as being amateur

Seeing as how you got help from SO I don't see how you solved your own problem. Obviously, the folks at SO were able to mind read a bit more than we were. Sorry about that. As for the incompetent (not spelled incompetant btw) remark, you couldn't be further from the truth. Especially with regards to Bear. All we wanted was for you to explain yourself better. But if you're happier at SO then I wish you the best of luck.
