Makes User Enter Answer Twice Before Prompt

Jun 10, 2009

The application works fine but it makes the user enter the answer twice before it brings up the question "Would you like to continue?". I thought the fix would be to just call "myMH.checkAnswer(studentAnswer);" straight from the method in the "appclass" but that didn't fix it I m so lost on this problem. This problem most likely is right in front of my face but don't see it lol. I have another question as well but I think if I get this one figured out first it might answer my other one.

Creating Form To Allow User To Enter Various Words?

Sep 30, 2009

I am new to JavaScript and was wonder how I would go about creating a form to allow the user to enter various words, one at a time. These words are added to an array and displayed in the page using the textarea form element. Each time a new word is entered, it is added to the array, and then the array is sorted in alphabetical order before the words in the array are displayed in the textarea, one per line. I have tried lots and lots of different methods to accomplish this, and I can get it half working when I use the alert function, but I need this to display on the page in a textarea rather than in an alert box, I tried to get it to write to the page using a document.write function, but like I said I am new to JavaScript and unfortunately cant get any of it working.

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html xmlns="[URL]">
<title>JavaScript Page One</title>
<BODY>
<CENTER>
<FORM name="history">
<INPUT name="command" type="text" value="">
<INPUT type="button" value="Add to List" onclick="f_store(document.history.command.value)">
<INPUT name="history" type="button" value="Show List" onclick="f_print()">
</FORM>
<P>
<SCRIPT language="JavaScript">
function MakeArray( n ) {
if( n <= 0 ) {
this.length = 0;
return this;

Clear Cache When A User Enters Something In Address Bar And Press Enter Key?

Sep 10, 2007

I am working on a online video portal build on flash/actionScript.

If I enter a url of a video when another video is playing, it doesn't playing the new video but it keeps on playing the old video. The reason I think is as it is a RIA, it doesn't refreshes the page and looks for a flash object and its already cached so it doesn't makes any http request in order to play the new video.

So I am planning to claer the cache.

how to clear the cache when a user enters something in address bar and press enter key?

JQuery :: HTTP GET Request When The User Presses "enter" When Inside Of An <input> Element?

Apr 8, 2010

For some reason, IE8 insists on submitting an HTTP GET request when the user presses "enter" when inside of an <input> element.It's a rather curious thing because I have an <input type="submit" /> that has an event for "click" that contains the following code:

event.preventDefault();
event.stopImmediatePropagation();

This works on Firefox - if the user presses "Enter" inside of an input element on the form, the submit button will not execute. But on IE, it does. However, if the IE user "clicks" the submit button, it does the right thing.Do I have to also override keydown events too and stop those? Why does Firefox and IE work differently here?

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
