Create Random Number Between 1 - 50 With Decimals?

May 24, 2011

How would I go about creating a random number between 1-50 that COULD include whole numbers, decimals to the tenth, hundredth and the thousandth place?
Ex) 2.145, 3, 5.8, 41.002, 10.12, 7, 18.023, 33.2

Also, if the only way to do it is to put trailing zeros to the thousandth place that's fine as well
Ex) 2.145, 3.00, 5.800, 41.002, 10.120, 7.00, 18.023, 33.200

This outputs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Create A Virtual Library - Make A Random Number Of Books Pop Out On Mouse Over?

Jun 7, 2011

I have a background that is a shelf full of books, I wanted to figure out what I would need to do in order to make a random number of books pop out on mouse over (individually), and upon click have the book pulled out and be flipped through and read like a book. Would I have to recreate the library picture completely to make the random books moveable? And would I have to create the books that I want to move from the bookshelf?

how to pull the book out from the book shelf so that it looks like it's coming towards me and then to make it look like it has been pulled out. Would I need to use animation for this? What would be the parts to the animation required?

A little background on my knowledge of javascript: I understand the concepts of it and can understand it when I read it or its explained to me. I am looking to create something as simple as I can, I thought having a background and something basic like a few books be able to pop out. When I realized css couldn't do this and css3 wasn't supported by most browsers I turned to javascript and have been trying to figure out the steps I would need to do to do this specifically.

Create A Small DHTML Code That Created A Unordered List Of Input Forms Dependent On The Number Selected From The Select Dropdown Menu

Oct 21, 2011

I wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:

Can I Increment Elements Each Loop?

Apr 15, 2011

I have written the follow code. It is meant to (when finished) output a table showing each member of the array PEOPLE. There Income ,there Tax bracket and there finally there total tax paid.The calulations in the if-else statements are correct.I have to create a loop that will go through the if else statements equal to the amount of the people in the array (This is no problem I have done this earlier)

My problem is when I try to add each element (PEOPLE) to the table or there indivual tax outcomes.Can I create a loop and increment in the elements each iteration to put on the table?(for there names) As I am not meant to store each iteration,it is to write to the table each time.This is the code I'm working on with out the loop.

HTML Tags Break - Won't Increment The Name?

Feb 5, 2010

The following is my javascript code to extend a form:

[Code]...

Everything works fine except for the counter/adding on to theName ( newField[i].name = theName + counter). I know exactly what the problem is... I just don't know how to fix it. If I remove the li tags, the counter will work fine and increment each "name". As soon as I put the li (see code above) tags back (or any html tag - I have tested others as well) - it breaks again and won't increment the name - it just submits the names without numbers and alas I have no usable post data. how to keep the html formatting there and still get the counter to increment the name?
