Calendar Selection - Comparing Two Dates For Validity
Sep 14, 2011
I have a pair of dates in a form that are made up of 3 text fields per date. The day and month fields are 2 digit, the year is 4 digit.
startday
startmonth
startyear
endday
endmonth
endyear
I can't easily change this for a number of reasons. I know the values themselves will be valid (they're generated by a calendar selection script) but I want to check the date created by the end variables is not before the start date. Any script to build a date from the 3 fields for each, and return false if the end date is earlier than the start date?

I am currently using a function to validate a form on the client side
(see code below). At the end of the function, I would like it to also
compare a startDate against an endDate to ensure that the endDate is
greater than (comes after) the startDate. The date format I'm using is
MM/DD/YYYY and it's writing to an MS SQL Server 2000 database table
via ASP. Code:

I have the following script
function timeDifference(laterdate,earlierdate) {
var difference = laterdate.getTime() - earlierdate.getTime();
var daysDifference = Math.floor(difference/1000/60/60/24);
difference -= daysDifference*1000*60*60*24
document.write('difference = ' + daysDifference + ' day/s ');
}
var laterdate = ?;
var earlierdate = ?;
timeDifference(laterdate,earlierdate);
//--></script>
And would like to insert my datein and dateout values where the ? marks are above in red. I can call these variables into the form on the page using <%=Request("datein")%> but how do I call a variable into the script above?

I have 2 different pages. one is where i will set the generic settings for golf course. the other is a reservations page which provides an option to add new reservation page. Now in the settings page i can set no of days to 1 thru 5. it will be inserted into config table in database. Based on this, on reservation page, i need to show only 1 or 2 or 5 days on the popup calendar starting from today which allows to select one while making new reservation.based on the setting if i can prepopulate those dates in a drop down list on the addreservation.php

I downloaded a calendar script that allows a user to just click on the date and have it populate the form input field- the problem is it lets you enter dates previous to today. I would like it so it could not enter any dates less than today.
Problem is, I know nothing about javascript. I am less than a noobie.
Would some kind soul have a look and see if it would be possible to do and show me what to do.
The code is below. There is also a css file which I did not include.
Code:
function positionInfo(object) {
var p_elm = object;
this.getElementLeft = getElementLeft;
function getElementLeft() {
[Code].....

I am working on a form where users enter a Start Date and an End Date via a pop up calendar using JavaScript. This works well. From the results of that data, I need to
1) Calculate the number of days + 1;
2) Multiply #1 by $25 to get the amount allocated for meals - and I need it done dynamically.
Now, I can get this to work using onblur in the two input fields for the dates, but that means users would have to put the focus within the input fields after they've done the calendars and tab or click else where in order for the values to take effect and the javascript to calculate the correct values for meal. It was suggested to try to use jquery, which I have been trying to no avail and I'm just wondering if I am doing this wrong. I thought .trigger or .triggerHandle would do it, but nothing seems to happen.
Here's my script I'm trying to use to activate these scripts:
<script type="text/javascript">
$("#en_date").blur(function() {
$("#input25").triggerHandler("blur");});
$("#input25").blur(function() {
$("#en_date").trigger("blur");
}
</script>
My input fields have this:
<br /><b>* Start date - </b>
<input type="text" id="st_date" name="st_date" maxlength="25" size="25" value="<?php echo $st_date; ?>" onblur="cal7();" />
<a href="#" onClick="cal13.select(document.forms[0].st_date,'st_date','yyyy-MM-dd'); return false;" TITLE="cal13.select(document.forms[0].st_date,'st_date','yyyy-MM-dd'); return false;" NAME="st_date" ID="st_date">
<img src="images/cal.gif" border="0" width="16" height="16" alt="Pick a date" />
</a><br />
<b>* End date - </b> .....
The End Date is tied to the Start Date, as you can tell above. For the calendar, I am making it launch with this command:
<SCRIPT LANGUAGE="JavaScript" ID="js13">
var cal13 = new CalendarPopup();
</SCRIPT>
I've tried just using a simple if/then statement within my javascript that calculates the values, but it doesn't launch automatically, which is my problem, and it should launch immediate after the "End Date" variable has been entered. Everything else works.

I'm working on redesign of a vacation rental company web site, and I'm looking to use a drop down calendar to select the arrival/departure date on the search form. getting the number of nights difference between dates (though I think the code/labels are slightly backward in that example), but I don't know where to start to split off the variables I need. Basically, the search.php file I'm passing the variables to need to be in this format:
Code:
search.php?month=(arrival month digit)&day=(arrival day digit)&year=(arrival year, 4 digits)&days_count=(number of nights)(...plus some other variables...)
how to split things off properly and get a properly formatted URL? I'll experiment a bit, and come back here with sample code

I have been checking out the calendar plugins and I was hoping I would find one in which I could display listed events during certain dates. For example, I have a web site for a divers club and we have events that happen on certain dates. I would like to have a calendar in which the user could click a certain date and something shows the user what is going on that day.

1. I have a javascript with which I am checking the validity of the email provided:
function checkEmail($email)
{
if(eregi("^[a-zA-Z0-9_]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$]", $email)) [code]...
2. Later I have another javascript which check the input field and changes the color if condition not met.
function validateForm (){
var value1 = document.getElementById('field1');
if(value1.value == "Fill in the Name") {value1.style.color = '#ff0000';} red letters IF NOT CHANGED
3. I want to include the above mentioned email function into this function as well.For example to do something like the following
if(value1.value == "" || checkEmail($email) != TRUE) {value1.style.color = '#ff0000';} red letters
Can I use information from another validation script (first script) or I need to include it inside the ValidateForm script (second script) as well?

I am creating a simon says game, the game is based on 4 images (each has an opposite) when the game begins one of the image randomly flashes, the flash is between itself and its opposite (day and night). the user is then to mimic that flash by clicking on that image. If he clicks in that image then i want the move to be correct or 'true' if he clicks on another image i want the move to be incorrect 'false'. if false he will be redirected to an alert box thats says game over, if true then 2 of the images then flash as opposed to only one, again randomly. I am unsure how to test if it is correct or incorrect and then if correct get 2 of the images to flash randomly and so on. Can anyone help? please? here is what i have so far:

I have the following regular expression to test the validity of an input date:
([0-9][0-9]|[0-9])[s/-]([0-9][0-9]|[0-9])[s/-]([0-9][0-9][0-9][0-9]|[0-9][0-9])
It should allow 1 or two digits for the day of the month, then a separating character (" ", "/" or "-"), then 1 or two digits for the month, then 2 or 4 digits for the year.
Unfortunately it will accept anything above 2 digits for the year, which I understand why is happening but don't know how to fix!

I have two strings that I need to compare and modify when there is a
matching value in the two. If strA = ??,' then I need to remove
the value ??,' from strB and the new value would be strB =
??,12935'
strA = ??,'
strB = ??,12937,12935' (these could be any values in any order)
I'm not sure where to begin on this.

I need to check if two hashes are identical.
My thoughts are something like this:
function compareHash(hash1,hash2){
if(hash1.length != hash2.length){return false}
for(var key in hash1){
if(hash1[key] != hash2[key]) return false;
}
return true;
}
Have I missed something, or is there a more direct approach?

I'm having trouble comparing 2 input boxes, using getElementById.
I have 81 hidden inputs (id's b0 through b80) and 81 input boxes (id's a0-a80). (Its just sudoku, so theres no security threat with them being viewable in the source)
I'm using this code (ill worry about the for loop later)
var solved = true;
if(document.getElementById(a0).value != document.getElementById(b0).value) {
solved = false
alert("not solved"); // debug
}
But it doesnt seem to be working. Im getting the error a0 is not defined. I know for sure that I have an input box with id=a0.

I need to test the contents of three fields to validate which contain text, and based on the results, set additional variables. I'm sure this is falling off the log simple, and I got it to work in PHP, but am having problems getting the syntax correct in Javascript.
In a nutshell, if a front AND a rear msg is entered, the price is $115, else the price is $80. I'm sure there's an easier way to code this than what I've done, but I don't know how to correctly perform several && and || in the same comparison.
Here's the PHP...
function notEmpty(){
var FrontMsgTxtTop = document.getElementById('FrontMsgTxtTop').value;
var FrontMsgTxtBottom = document.getElementById('FrontMsgTxtBottom').value;
var RearMsgTxt = document.getElementById('RearMsgTxt').value;
