## Allow User To Input A Number Say 1-200 And That Variable Would Make Up The Last Part Of An IP Address

## Creating A Form That Will Change The Number Of Fields Based On User Input

Jan 4, 2006

I have a form that collects information about up to 5 items. I would
like the user to be able to select from a drop down menu how many items
for which they want to compare information, and then have the form
change the number of input fields accordingly.

In other words, if the user selects enter info for 3 items, then input
fields for only 3 items are shown, if they change it to 4 items, then a
fourth column shows up in the table with the appropriate input fields.

## Limit To Number Of Loop Iterations?

Mar 24, 2011

I wrote a short javascript code to try to solve a math puzzle. It involves iterating 50,000 times through a for loop. Nested in each of those iterations is another for loop with 50,000 iterations of its own. I think that's 2.5 billion altogether. Each times it compares two numbers that are being incremented.

I'm doing this in JS because I can't any of the Java I learned a few years ago...

I tested the code with much smaller numbers and it worked. With the big numbers my browsers are not responding, not surprisingly (I'm using the latest firefox on the latest mac os).

Will the code finish running tonight? Next week? In 10 years?

## Limit Number Of Checkboxes Selected?

Feb 25, 2010

## Limit On Number Or Size Of Javascript Variables

Jul 20, 2005

There will be a number of list boxes and other controls, with pop-up windows
to edit certain properties. It's the kind of thing I would normally have
done in VB but I want it to be browser-based. I've only used javascript for
trivial things before so this would be my first serious javascript
development. I would like it to run on all reasonably recent browsers.

The form starts with all the initial values being received from the server
(presumably just by pre-initialised data structures). The user tinkers with
it and when he is happy he presses 'submit' and the whole lot is submitted
to the server (presumably as a form post). This would be a few kb of data,
possibly 100 individual values but obviously in various data structures. I
guess there would be a few hundred lines of javascript code to manipulate
it.

My question is, is there likely to be a problem with manipulating and
sending this amount of data in Javascript. Sorry if this is a dumb question,
but like I said, I only used javascript for tiny programs before, so I'm a

## Limit Number Of Selections In Multiple Select List Box

Netscape6+.

## Resolved Adding / Removing And Incorporate A Way For A Limit On The Number Of Fields

Mar 8, 2011

I'm trying to get my script below working. I've managed to get it to add fields dynamically but the remove function isn't right... and I can't think of a way round it. how can i incorporate a way for a limit on the number of fields that can be added?

<script type="text/javascript">
{
var x = document.getElementById("inputs");
x.innerHTML += "<input type="text" />";
}
function removeInput()
