JavaScript - How To Find Day From Any Date.
Hi All,
I have the date in 2009-10-24 format.can anyone tell how can I get the day of any particular date entered by user. Thanks in advance... Similar TutorialsNot sure if this is possible in javascript: I'm looking for two different dates (bill date and due date) on an invoice that are captured by OCR. If one of them exists, but the other does not, I want the empty field to be 14 days before (or after) the other. For example: if the bill date is 7/27/2010 and the due date was not captured, I want to set the due date as 8/10/2010 (14 days after the bill date). If the due date was captured as 8/10/2010, but the due date is blank, I want to assign the bill date as 7/27/2010 (14 days before the due date). if both dates have values, do nothing. Thanks. Using Adobe Form Javascript validation, how would I do this code for Visual Basic in Javascript (non web) Code: If PurchaseDate.Value > Date Then
MsgBox ("PurchaseDate cannot be greater than Today's Date!")
Cancel = True
End If
Something along these lines but this isnt working: Code: If (PurchaseDate.Value > Date) Then
{
app.alert ("Purchase Date cannot be greater than Today's Date!");
}
Thanks I have a drop down menu where people can select a month, day and year. Based on their selection, I want to show them an image. If their selection is >= July 26, 2010 but <= July 25, 2011, show the red image; If their selection is >= July 26, 2011 but <= July 25, 2012, show the white image; If their selection is >= July 26, 2012 but <= July 25, 2013, show the blue image; If their selection is >= July 26, 2013 but <= July 25, 2014, show the yellow image; I don't know how to compare a selected date to a range of dates like this. Hi, I've inherited a Form which calculates a future date based on a calculation and then inserts today's date and the future date into a database. The day part of the date is formatted as a number. This is fine, but up to 9 the numbers display in single figures with no leading zeros. I want them to display leading zeros (e.g. 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11... 30, 31) So; 1/12/2010 is NOT wanted 01/12/2010 IS wanted The inherited code originally set the Month names as "Jan", "Feb" etc, and it was easy to kludge these to 01, 02... 12, but I suspect there's a more elgant solution to this as well, this bit of the code works so it's not as vital to neaten this but my database needs dd/mm/yyyy format (it's a third party email program). Code: </script>
<script type="text/javascript">
var todaysDate = new Date();
function updateExpiryDate(){
var weeklyMileage = document.getElementById('AvWeeklyMileage').value;
var expiryDate;
var weeks = 0;
var expiryDateString = '';
if (!isNaN(parseInt(weeklyMileage))){
weeks = 700/weeklyMileage;
expiryDate = new Date(todaysDate.getTime() + (1000 * 3600 * 24 * 7 * weeks));
var expiryDateString = expiryDate.getDate() + '/' + getMonthString(expiryDate.getMonth()+1) + '/' + expiryDate.getFullYear();
document.getElementById('expiryDate').innerHTML = expiryDateString;
document.getElementById('ShoeExpiryDate').value = expiryDateString;
} else {
document.getElementById('ShoeExpiryDate').value = '';
document.getElementById('expiryDate').innerHTML = 'Please enter a valid weekly average mileage'
}
}
function getMonthString(monthNumber){
var monthString = "";
switch(monthNumber){
case 1:
monthString = "01";
break;
case 2:
monthString = "02";
break;
case 3:
monthString = "03";
break;
case 4:
monthString = "04";
break;
case 5:
monthString = "05";
break;
case 6:
monthString = "06";
break;
case 7:
monthString = "07";
break;
case 8:
monthString = "08";
break;
case 9:
monthString = "09";
break;
case 10:
monthString = "10";
break;
case 11:
monthString = "11";
break;
case 12:
monthString = "12";
break;
default:
// do nothing;
}
return monthString;
}
function setTodaysDate(){
var todaysDateString = todaysDate.getDate() + '/' + getMonthString(todaysDate.getMonth()+1) + '/' + todaysDate.getFullYear();
document.getElementById('todaysDate').innerHTML =todaysDateString;
document.getElementById('DateOfPurchase').value = todaysDateString;
}

How can I use the following code below to save the date from my popup window datepicker back into a var and relay it back onto its parent page? I can't seem to figure this out: Code: <html>

Also i want to add a datepicke to this textbox..how it is posible / other option is to use Jquery datepicker but could not know how to impement it thanks again Hi, I've been trying to code a javascript fonction that uses Window.find and I'm having problems doing exactly what I want. I don't know much of java and I understand that it's not everyone who's willing to do all the work for me so I'm looking for a very kind person here I want it to find a specific string that won't change (so no use to prompt for it) in another existing page that would be loaded in a frame. When the string is found, a sound is played like an alarm. The entire thing should reload every like 5 minutes. That's the easy part. I'm having trouble with the "If found in the frame, play a sound part". I don't think it's pretty hard to do, but hey, I can't do it. As I said earlier, I understand I ask for someone to do the whole thing for me but I'm willing to pay by paypal for the service. Let's say... I don't know, ten bucks should do it. I think I've been clear with what I need but if not, please feel free to ask for more specifications. Thanks for your time. This is a function designed to return an array of all elements in "body" with a particular tag name and class name. It works fine up until the if (needles.length == 0); { line, according to my debugging. It seems to fail there though and I can't figure out why. It's probably just some noob error that I've missed but I can't for the life of me find it Thanks in advance for any help, it's greatly appreciated! Code: function getElementsByClassName(tagname, classname) {
var haystack = document.getElementById('body').getElementsByTagName(tagname);
var needles = [];
var i;
for (i in haystack) {
if (haystack[i].hasClassName(classname)) {
needles.push(haystack[i]);
continue;
}
}
if (needles.length == 0); {
needles = 0;
}
return needles;
}
Hello. Please excuse my ignorance but I am not too clued up on javascript. Im hoping someone may be able to help me out here. I have managed to locate a script which will find text on a page, but I have a couple of requests. Firstly the script will only search up. I would like the search box to be at the top of a page but the only way to get it to work correctly is placing it at the bottom of the page. Secondly would some kind soul advise me how to place the script in an external file and then link to it. Thanks in advance. function textSize(updown) { var size = Number(readCookie('user-font-size')); if (size == 0) { size = 12; // No Cookie, Set A Default Size Of 12px } size = size + Number(updown); // Adjust The Current Size if (size > 20) { size = 20; } // Stop At 13 if (size < 12) { size = 12; } // Stop At 10 writeCookie('user-font-size', size, 12); // Update The Cookie document.body.style.fontSize = size + 'px'; // Set The Users Text Size } function writeCookie(name, value, days) { if (days) { var date = new Date(); date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000)); var expires = '; expires=' + date.toGMTString(); } else { expires = ''; } document.cookie = name + '=' + value + expires; } function readCookie(name) { name += '='; var cs = document.cookie.split(';'); for (var i = 0; i < cs.length; i++) { var c = cs[i]; while (c.charAt(0) == ' ') { c = c.substring(1, c.length); } if (c.indexOf(name) == 0) { //-----------// return c.substring(name.length, c.length); // Gotcha // } //-----------// } //------------// return null; // Failed // } //------------ <img id="plustext" class="zoom-in" alt="Increase text size" src="Zoom-In-icon.png" onclick="textSize (2);" style="cursorointer" /> <img id="minustext" class="zoom-out" alt="Decrease text size" src="Zoom-Out-icon.png" onclick="textSize (-2);" style="cursorointer" /> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Hello, Below is the javascript I'm debugging (or trying to) but just can't see where the error is: The code should send a message "GOOODDD!!!" when the input box is empty (nothing typed in) and should send a message (BAAADD!!!) when a string of theee a's are typed in ("aaa"). The problem is that no matter what I type in the script ALWAYS sends me a "GOOODD!!" message. I guess it is a simple glitch but I just can't figure it out. I'd appreciate any help Thank You. Code: <script language="javascript" type="text/javascript">
<!--
function textCheck(that)
{
var mytext=document.getElementById("BLABLA")
if (mytext == "aaa")
alert("BAAAAADDDDD!!!!" + mytext.value);
else
alert(" GOOOODDDD!!!!" + mytext.value);
}
-->
</script>
</head>
<body>
<form id="form1" method="get" onsubmit="textCheck(this)" />
<input name="BLABLA"

(Taken from external website so I can understand how it works). I need some help finding a "find on page" script that will display the results in the middle of the page for IE. I have tried several different ones to no avail. The ones that work in all the browsers display the result in IE at the very bottom of the page. I am not very familiar with programing in Java and I am unable to modify any for my needs. The one I found that did work in IE didn't work in any other browsers. Please help, Thx
Hi all. Is it possible to command a find in page search from another html? I have a 'main page' and 'directory page' The directory page has find in page command on it, so if users can open the directory link from the main page and then search that page using the find in page search box. To speed this up, is there any way I can have a text box on my main page that when I enter text and submit that it carries across the text entry to the find in page box on the directory page and starts this search for me? I need to complete this using javascript so if this is possible I would great appreciate any help. Thanks Hi All, Just a quick question! Is it possible to have a text box input searching for the entered text on another webpage in the same way Find In Page would do? I have a webpage that I want users to input an item, and that this will open the targeted webpage and bring you to (and highlight) the matched item(s) like find in page does. Is this possible or is the easiest way to just make users open the link to the target page and just complete the find in page search there? Thanks Glen |
