JavaScript - Javascript Error, Leap Year Issue.
I have the following, but not sure why it isn't picking up this year as a leap year. Any idea?
Code: CalendarMonth.prototype.correctForLeapYear = function()
{
if(this.year%4 != 0)
{
daysInMonth[1] = 28;
this.isLeapYear = 0;
}
else if(this.year%400 == 0)
{
daysInMonth[1] = 29;
this.isLeapYear = 1;
}
else if(this.year%100 == 0)
{
daysInMonth[1] = 28;
this.isLeapYear = 0;
}
else
{
daysInMonth[1] = 29;
this.isLeapYear = 1;
}
}
Thanks Martin Similar TutorialsOn my site I have a Javascript error in my FireBug console: Year is 'null' Code: document.getElementById('year').options[i] = new Option(curr_year-i,curr_year-i);
here is my site: http://harveys.blueplanetdns.com/harveys-shop/ uncaught exception: Syntax error, unrecognized expression:
Code: :([rel*=qnt_Rc]) I have this code: Code: grpDiv = $$('div:([rel*=' + txt_val + '])');
Which when operaterated on, we have: Code: grpDiv = $$('div:([rel*=qnt_Rc])
This error: uncaught exception: Syntax error, unrecognized expression: Code: :([rel*=qnt_Rc]) Is new. The code in question has been around for about a year and no issues with prototype 1.6.1. Yet we upgraded to 1.7, and this error started showing. any ideas what this could be and how to fix it? thanks Hi guys , How it is possible to get current & next year months and put them into array ..i.e Jan-11 --- M1[0] . . . . Dec-11 M1[11] Jan-12 M2[0] . . . Dec-13 M2[11] thanks Hello guys, I really need some help with this.

any ideas? Hello all I have this code to write the year which works fine in ie ff but apparantly is not working in google chrome. I don't have chrome and so can't check can anybody tell me why chrome has an issue with it? What should I change to make it chrome compliant:-) In ie ff it displays 2012 correctly but in chrome i'm told it is showing 112 ro something like that. Code: Code: any help very much appreciated LT I want to create an array for a religious website that will display a different Bible verse for each day of the year. This is how I incremented each day of the year. Code: var myDate=new Date(); myDate.setFullYear(2011,2,4); myDate.setDate(myDate.getDate()+1); How do I make the connection between the array and the new date as it changes? This is a snippet from the array. Code: var dailyVerseRef=new Array(); dailyVerseRef[0]="Genesis 1:1"; dailyVerseRef[2]="Genesis 1:2"; dailyVerseRef[3]="Genesis 1:3"; dailyVerseRef[4]="Genesis 1:4"; dailyVerseRef[5]="Genesis 1:5"; dailyVerseRef[6]="Genesis 1:6"; dailyVerseRef[7]="Genesis 1:7"; dailyVerseRef[8]="Genesis 1:8"; I used a switch to go through the days of the week, but to go through the days of the year seems more difficult.

I am very new to coding, I am currently working on this design as my very first: http://img822.imageshack.us/img822/6533/unled1pd.jpg. I am currently working on the Image slider which is on the left side next to the login bar and headlines. I don't know where to start with this. If someone could walk me through or help me in anyway i would greatly appreciate it. Here is my current project LIVE: http://visionarycreativegrp.com/Demos/ForSale%20RED/# Hi All, I am using a script that hides / shows a cell row depending on whether a form checkbox has been ticked. The HTML, CSS and JS code is below: CSS & HTML (simplified and normally in head / body tags etc.): Code: #lastRow { display: none;}
<table>
<tr>
<td>Events Xtra:</td>
<td><input class="text" type="Checkbox" name="upcoming" id="upcoming" value="checked"></em></td>
</tr>
<tr id="lastRow">
<td>Xtra Description:</td>
<td><textarea name="event_description" cols="60" rows="5" id="event_description"></textarea></td>
</tr>
</table>
JS: Code: function showHideRow(obj){
oLastRow.style.display = (obj.checked)? 'block' : 'none';
}
window.onload=function(){
var oChkBox = document.getElementById('upcoming');
oLastRow = document.getElementById('lastRow');
oChkBox.onclick=function(){showHideRow(this);}
showHideRow(oChkBox);
}
Now, the above works absolutely perfectly in Internet Explorer - when the checkbox is ticked, it displays the bottom row exactly as I want it to - i.e. as the next row in the table. However, in Chrome, Safari and Firefox it seems to display the whole row as a cell on it's own so distorting the entire table structure. I suspect it is something to do with the use of the id="lastRow", but I am not sure. The strange thing is that the HTML source is of course the same for both. Can anyone shed any light here? For convenience I have uploaded two images: IE (working fine): Firefox (distorting across page) Regards, Neil Happy Star Wars Day! Hopefully someone is strong in the force and can help. I have a HTML form and I need to get the user to select one of 350 options. I have broken down the options into "Major Group", "Sub-Major Group", "Minor Group" and "Unit" I'm looking to create 4 dynamically changing drop down lists to point the user to their final choice. All 350 options are in one database table with the following headings: [Major Group][Major Group Title][SubMajor Group][SubMajor Group Title][Minor Group][Minor Group Title][Unit][Unit Title] The 'groups' are numeric, and the title's alphanumeric. I have used the MySQL database to achieve this as it makes it easier to update the 350 options in the future should I need to. As far as the tutorial over at W3Schools.com has advised I need to use the following process: HTML Form - <Select> onclick run Javascript function Javascript function connects to server via PHP PHP runs query on the MySQL database and returns results Javascript then populates the 2nd drop down. and so on through to the final drop down. There are never more than 9 options in each drop down. Please can someone help me set this up. I have been using the code examples from W3Schools.com to put the following together. I use the alerts to check it's progress. It seems to be getting stuck when checking that the "if (xmlhttp.readystate==4)" line. Using Safari's built in Debug console the error I get back is that the php file cannot be found and there is a "500 Internal Server Error" - although I think (read as: assume) this is because the "if (xmlhttp.readystate==4)" isn't working. Any help would be much appreciated. Code: function selectMajor(str)
{
// an alert box to show that both a value has passed and it is the right type
alert(SOC_Major.value);
// enable the next drop down - SOC_SubMajor
document.getElementById('SOC_SubMajor').disabled=false;
// clear the next select box?
document.Add_Vacancy.SOC_SubMajor.options.length=0
// POST to the php script
// AJAX goes here
if (str=="")
{
document.getElementById('SOC_SubMajor').innerHTML=" ";
alert("str is empty");
return;
}
if (window.XMLHttpRequest)
{ // code for IE7+, Firefox, Chrome, opera, Safari
xmlhttp=new XMLHttpRequest();
alert("new XMLHttpRequest created");
}
else
{ // code for IE6, IE5
xmlhttp=new ActiveXObject('Microsoft.XMLHTTP');
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readystate==4)
{
alert("xmlhttp.readystate = 4");
if(xmlhttp.status==200)
{
alert("xmlhttp.status = 200")
document.getElementById('SOC_SubMajor').innerHTML=xmlhttp.responseText;
}
else
{
alert("There was a problem while using XMLHTTP:\n");
}
}
}
xmlhttp.open("POST","scripts/SOCSubMajorSelect.php?q="+str,true);
xmlhttp.send();

Hi I am trying to build an application which has 6 small input fields and one numeric key pad. Initially the focus should be on the first inputfield and after entering the number from the numeric key pad, it should shift the focus to third input field and the user should be able to enter the number from the numeric key pad and then shift the focus to fifth input field and user should be able to enter the number in fifth through the key pad. I have achieved till gaining the focus on the first input field and i could enter the number through the key pad and i was able to shift the focus to third input field but however whatever i enter the number is getting changed in first and third input field. the code i wrote is below Code:
<html>
<head>
<script type="text/javascript">
function displaymessage(val)
{
document.getElementById('first').value = val;
alert(document.getElementById('first').value);
if(document.getElementById('first').value!=null)
{
alert("yes");
document.getElementById('third').focus();
document.getElementById('third').value = val;
}
}
</script>
</head>
<body onload="document.getElementById('first').focus();">
Enter your pin:
<input type="text" id="first" size="1" maxlength="1"></>

I'm trying to use SmoothGallery 2.1 on my website as a featured box. I tried opening the demos provided with the code in all browsers to make sure it was compatible and it showed fine in them all. I copied the javascript onto my site and I'm able to show the gallery. However in Chrome and Internet Explorer it shows fine, but Firefox the images are spread vertically down my site and the javascript gallery box doesn't show. I don't understand why this is an issue because it shows fine opening the demo pages and the javascript code and css is a straight copy from the folder :S Can anyone help me out?

I believe the issue is in here somewhere but I'm not sure where. Ironically I'm learning from a book and this is from the Error handling/Debugging chapter. I'm going well on this book so far and really don't want to have to move forward without fully understanding whats going on. Any help/comments would be greatly received. Sara |
