Form Entry To Time Part Of Database Date Entry?

Aug 1, 2005

I have a textbox on one of my forms that is used to accept a time from the
user. I need to write this value to a database to trigger an event later on.

What I'd like to know is...

Are there any functions in javascript that can convert different time
formats to a known format (24 hour clock)... 5pm -> 17:00 or 5:00 to 05:00,
etc. ???

Assuming that I get the input into a 24 hour format, how can I create a full
time/date variable with todays date and the users entered time?

Finally, if the entered time is earlier than the current time, how can I
create the above date/time combination using tomorrows date?

If Else - When I Input An Invalid Or A Valid Entry, It Is Continuing To Ask Me To Input Again An Entry?

Jan 17, 2010

There is a missing part on my program, it is when you input less than or equal to 65 and greater than 100, a prompt will appear and say "Invalid Entry" and ask you to Input again an entry until you enter a valid entry. For example on Prelim Grade, I input 50, a prompt must appear to say "Invalid Entry" and ask me to input again another entry. Another is how will I terminate the program? When I input an invalid or a valid entry, it is continuing to ask me to input again an entry.Here is my code

Code:
<html>
<head>[code]......

Index Of An Array Entry

Mar 24, 2006

I'm refering to an entry in an array by it's string key, as in
foo["bar"]. Is there a way to get the numeric index of that array
without iterating through the entire array?

What I need to do is find the "next" or "previous" entry in the array,
but the keys are strings, instead of numerical indeces.

-> Inline Date Entry? How? <-

Apr 4, 2007

I'm looking for a way to have the user enter a date as 03042007
for April 3rd 2007, and have that turned into 03.04.2007 as you type.

Is there an easy way to have "03" automatically turned into "03.",
then the next two digits into "04." to construct the valid date entry
as you go?

I'm trying to get the same effect as what you have, for those of you
who know Delphi or C++Builder, an EditMask field like "##.##.####"

Is this possible?

2 Sites To Have Pop-up On Entry, Then Not Show Again?

Sep 10, 2011

I'm making 2 sites and need a visitor who lands on the home page of either site to first be shown a page that shows a company introduction and 2 links at the bottom so they can choose which division of the site (which website) they want to go to.Does anyone know of any pre-made java or other code that would allow for this? So that a visitor doesn't get stuck in a cycle of being taken from one home page to the other and having the pop-up every time, I'm thinking it will likely need to write a cookie saying they've seen the pop up, then it won't appear again.Each site would then have to check for a cookie from either site.

Keep Users From Messing Up Entry?

Jul 28, 2007

As you can see it adds a linebreak after each text is added. It is meant to creat a list to be output from a form. But a user can click inside the textarea end mess up the list and enter anyway they want.

How can I make sure that there is always a linebreak between each line of text?

<input size="20" id="inputtext">
<input name="add" value="Add"

'" type="button">
<textarea rows="15" id="textarea" name="box" cols="22"></textarea>

Jun 15, 2009

I have a form with firstname in one field and lastname is another field. I need to manipulate the entry so if someone enters Joe for the firstname and Smith for the second name it will be changed to Smith,Joe. Here is my attempt but it just switched the fields and didnt manipulate how I wanted it:

var pattern = /^([a-z-]+)s+([a-z-']+)$/gi;
name = name.replace(pattern, "$2,$1");
name = name.replace(/,/, " ");

Date Entry Validation Gets Stuck?

Jun 23, 2011

I have a CF application that accepts two dates. The first date - Out Date - is required. The second date - Return Date - is optional, but if populated, must be equal to or greater than the Out Date. Here's the screen & code:

9974
<script type="text/javascript">
function compareDate()
{ if(document.editleave.temp_ret_date.value != "01/01/0001")[code]....

Everything works fine....EXCEPT...if the Return Date is invalid, I cannot click on the calendar box to select a date (or open another browser session). Basically, IE is locked up until the user manually types in a valid date.This ain't good.I want to be able to trap the error, just like I have, but I still want the calendar selection box to be usable.Is it possible to "reset" the error condition after the intial warning to only trigger on the onSubmit parameter?

Select A Random Entry From An Array?

Aug 30, 2010

So, I am attempting to select a random entry from an array, and then make it so that particular entry will not be selected again until every entry has been selected. Basically, I don't want to see any of the same entries, until all of the entries in the array have been selected.

So if this were my array....

keywords =
[
"ppc",
"games",

[Code]....

since meta was selected a second time before everything had been selected once.

I would like to see something more like

meta, advertise, gaming,ppc, welcome, home, games, advertise, ppc, since this did not select any entry multiple times before every entry had been randomly selected.( the second loop started at the second "advertise" in case you didn't catch the differences.

But as you can see from the code that I have posted above, I do not know how to do this. I have seen examples where the entries that were randomly selected, were actually deleted from the array entirely but this is not what I want to do. I just want every entry to be selected once, and then for the process to be restarted.

Address Bar Entry And Changing Swf Variables?

Feb 19, 2009

i have no particular knowledge of javascript and web development in general, but I have some grasp of it. My question is not about javascript coding, but about using javascript to change the parameters of a website with a swf file, this one in particular: (get ready for a long url, since I can't post links)

[Code]...

This may be a long post, but I just wanted to make everything clear. And thank you very much for reading my question, and thank you even more for giving me suggestions. If you need to ask anything else from me, I would gladly answer.

And although I don't know squat about javascript, this is relevant to me because I am a freelance artist. I go on that website in my free time. Anyways, thank you very much for taking your time to read this, and I hope you may have answers to my problem.

Popup Entry Window Focus

Jun 28, 2005

I am working on a ASP.NET application and have some forms that require to be popped up and let the user edit information on them. These windows must stay in focus until closed, but I have having some issues implementing this.

We are targeting IE explorers and have tried the showModal() which is exactly what we require (as it forces the user to the window till complete) but the page cannot refresh/postback which is what we need.

I also tried the on blur = self.focus() but that doesnt work either as when I user clicks the textbox on that popup to update a datagrid the focus is taken off the textbox and to the window again.

What I'm trying to achieve it a popup window that has focus until complete and allows the window to refresh as it requires use to update & delete a datagrid. Any ideas?

I have considered the readonly option but I need users to be able to delete entries.
