Dynamically generating input grid

Question

I am trying to figure out a way to let users dynamically generate rows of input text boxes using a button in an HTML page e.g. user will enter text in say 10 columns and then hit enter, which will create another row of text boxes with same number of columns. Also all the text boxes should automatically generate their names e.g. if the column name is "Address" then the name of the first address text box in the first row should be e.g. "address_1" and then name of the second address text box should be e.g. "address_2".
I want to do this on the client side, so that I can gather all the information and then only pass it on to the server.
Any help would be greatly appreciated.
Thx

Answer 1

Depends on how you have build your JSP page. Assuming:
1. You have built your .JSP with one or more .java files. Then the previous example that our friend answered you is write but converted into java code and not in javascript. In case you dont understand how you can build a JSP file with .java file i explain:
you write Java code in a .java file but it has HTML tags. When your code is executed the tags are "created" because your code says so. And this is the way your .JSP is being built. In there you can create a sequence with for or anything else you figure out to build more and more lines. For the names figure out a generator method.
2. You have built your code with another tool (Dreamweaver) and you dont want or know to use java code to create more lines. Then i suggest you a middle way:
Figure out how many lines will be created from your users more or less. Let's say that more or less users create from 4-6 lines. Create your lines already, put names on them with a generator but have them disabled (type="textfield" ....... disabled>). Then use javascript so when the user wants to have more lines or rows allow with javascript the second row to be enabled and so on. When you reach your final line or row but the user still wants more lines, have a button saying "More" or sth like that and reload the page but be sure to store the previous entered values. I hope i helped.
P.S. Maybe also try to change that by putting a textarea unless it doesnt help. Let me know what you think.
