JavaScript - Year Is 'null'?
On 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/ Similar TutorialsHi i have done some reading on the net today because i am getting an error on ie. I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory.

Another Update. I am back to the original question. null is null or not an object.. in my search i have found this found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so. object.onchange = function() {} i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines Hi I am having trouble with a script. I cannot figure out why I get the message: error: null is null or not an object (In IE8) The site is: www.rayburns.com I have check the javascript for the navigation bar and for the rotating images and cannot see what is missing. Not sure what is not being called. Can someone please help with this. Thank you in advance! Hi I've implemented Busybox on a website to display FLV files in a popup player. This works fine, except for the following error in IE (FF is fine) when I close the popup: 'null' is null or not an object I think I've narrowed it down to the following block of code, but am stuck as to what to do from here. Code: var cl = new Element('img',{
'styles':{
width:'24px',
height:'24px',
position:'absolute',
top:'-20px',
right:'-20px',
'z-index':'100000'
},
'src':'bumpbox/closed.png',
'id':'closer'
})
cl.addEvent('click',function(e){
e = new Event(e).stop();
bg.dispose();
$(el).getChildren().dispose();
eff2.start({
'width':[maxw,1],
'height':[maxh,1],
'left': [endleft,middleH],
'top': [endtop, middleV+s]
})
})
The IE error is just giving me line number 1 of the php, but the error, I'm sure, lays in the Javascript. Many thanks Hello guys, I really need some help with this. I am using the jQuery cookie file to set and retrieve my cookies, but I don't know how to modify it to set all cookies for more than one day. Here's my code: Code: /**

I was told to put this in the head section before my page, and it sets it for a year, but I want all the cookies set on the page to be set for a year. Code: $(function() {
$.cookie('name', 'value', {expires: 365});
});
any ideas? 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 It should be this one: http://www.codeschool.com/courses/jq...r-first-flight Great class! they run you through the basics and have you do excercises on the site itself at the end of each chapter. when you submit the code it checks the code and gives you hints if somethings wrong. Very through and easy to understand. Seriously folks, if your just starting or even if you think you know everything, you still might want to watch some of this. ok. im done. no this isnt spam I dont work for the company, I jjust really enjoyed it. 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. 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 hi the title pretty much says it but il go into a little more deph, im looking for a piece of script that i can insert into my masterpage which will fetch the year from the server and display it on the footer. just to save our company updating the dates each year. cheers, ant. 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 Hi.. I just want to know how can I display Weeks in a drop down list per year. Thank you Good morning Guru's and Experts, I really need your help with this one. It seems that the function this_week('end') is returning a bad date of 12/33/2014 (mm/dd/yyyy) where it should properly read: 01/02/2015 Code: function this_week(x) {
var today, todayNumber, fridayNumber, sundayNumber, monday, friday;
today = new Date();
todayNumber = today.getDay();
mondayNumber = 1 - todayNumber;
fridayNumber = 5 - todayNumber;
if (x === 'start') {
//var start_dd = today.getDate() + mondayNumber
var start_dd = today.getDate()
var start_mm = today.getMonth() + 1
var start_yyyy = today.getFullYear()
return start_mm + '/' + start_dd + '/' + start_yyyy
}
if (x === 'end') {
var end_dd = today.getDate() + fridayNumber
var end_mm = today.getMonth() + 1
var end_yyyy = today.getFullYear()
return end_mm + '/' + end_dd + '/' + end_yyyy
}
}

Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts I understand that you are trying to get the date next Friday. Try this script:- Code: <span id = "info"></span>
<script type = "text/javascript">
var curr = new Date(); // get current date
var first = curr.getUTCDate() - curr.getUTCDay(); // First day is the day of the month - the day of the week
var last = first + 5; // last day is the first day + 5 = Friday
var lastday = new Date(curr.setDate(last));
var yy = lastday.getUTCFullYear();
var mth = lastday.getUTCMonth()+1;
if (mth<10) {mth = "0" + mth}
var dy = lastday.getUTCDate();
if (dy<10) {dy = "0" + dy}
// now manipulate the display of year,month,date as desired
var result = mth + "/" + dy + "/" + yy;
document.getElementById("info").innerHTML = "Week Ending Friday " + result;
</script>
Lottery: A tax on people who are bad at math. I know that unlike PHP, NULL in JavaScript must be quoted as a string. Does it matter if you use single or double quote?
New problem, taken from another website I posted this on: Error: Code: Error ``user_node[0].firstChild is null'' [x-] in file ``*url removed*'', line 63, character 0. As you can see it says that the value is NULL although it shouldn't be... Here is the JavaScript which the error refers to: Code: function manageMessage() {
if( receiveReq.readyState == 4 ) { // request complete
var chat_div = document.getElementById( 'chat' );
var xmldoc = receiveReq.responseXML;
var msg_nodes = xmldoc.getElementsByTagName( 'message' );
var n_msg = msg_nodes.length;
for( i = 0; i < n_msg; i++ ) {
alert(i + "," + n_msg);
var user_node = msg_nodes[ i ].getElementsByTagName( 'user' );
var time_node = msg_nodes[ i ].getElementsByTagName( 'time' );
var text_node = msg_nodes[ i ].getElementsByTagName( 'text' );
alert(user_node[0].firstChild.nodeValue);
//Display message
chat_div.innerHTML += user_node[ 0 ].firstChild.nodeValue + "<br />";
chat_div.innerHTML += time_node[ 0 ].firstChild.nodeValue + "<br />";
chat_div.innerHTML += text_node[ 0 ].firstChild.nodeValue + "<br /><br />";
}
}
}
And again, the whole script if you want it... Code: <script type="text/javascript">

I'm guessing this question will be one of the easiest questions ever posted but I'm just not getting this fix. I have a simple Javascript program that calculates a users pace for their run. The inputs are done through an HTML Form. The user can input hours, minutes, & seconds of their run. Then the distance number & measurment. Then finally the pace desired. I am having some trouble with null values in this program. If I input a 0 in hours and then fill everything out the program works great. 100%! But, if I leave the field blank and hit calculate I get a NaN. I'm guessing I need some kind of statement like if this value is null set it to zero but I am not having any luck with exactly what kind of syntax I need. So here is the code, again not very complex, any help would be greatly appreciated! function calculateTime(){ var time_hour = parseInt(document.getElementById("time_hour").value); var time_min = parseInt(document.getElementById("time_minute").value); var time_sec = parseFloat(document.getElementById("time_second").value); var dist_num = parseFloat(document.getElementById("dist_num").value); var pace_choice = document.getElementById("pace_choice").selectedIndex; var dist_choice = document.getElementById("dist_choice").selectedIndex; var total_sec = (time_hour * 3600) + (time_min * 60) + (time_sec); // Then I'm guessing my if statement would go here somewhere? For some reason i'm getting the error of "length is null". Which is from this . Code: function display_form(id) {
//Create some variables
var html = "";
var container = "form_container";
var menu = load_menu(id, false);
//Get id
for ( var i = 0; i < menu.length; i++ ) {
alert(i);
}
http = getHTTPObject();
http.onreadystatechange = function() {
if ( http.readyState == 4 && http.status == 200 ) {
document.getElementById(container).innerHTML = http.responseText;
} else {
document.getElemenyById(container).innerHTML = "Loading...";
}
}
http.open( "GET", "includes/forms.php?form=" + id );
http.send();
//Watch input fields
//login_listener();
}/*
Here is the function: Code: function load_menu(menu, return_d) {
//Availible menus
var data = [];
data [ 'login' ] = [ 'Login', 'Register', 'Recovery' ];
data [ 'settings' ] = [ 'Profile', 'Account', 'something' ];
if (return_d == false) {
return data[ menu ];
} else {
//Menu container ID's
var cons = Array('menuitem1','menuitem2','menuitem3');
for ( var i = 0; i < cons.length; i++ ) {
document.getElementById(cons[i]).innerHTML += data[ menu ] [ i ];
}
}
}
Extra info: id = login menu = login I need to check to see if a cookie has been previously created: Code: var startnum = readCookie('a1');
if (document.cookie.indexOf('a1') == -1){
var startnum = "0";
}
Should line 2 be: Code: if (document.cookie.indexOf('a1') == null){
? Does == -1 do the same thing? Bonjour all. I am trying to activate a function once an iframe is closed. so i am trying to use: window.opener.pageUpdate(); which i get an error of Error: window.opener is undefined Source File: https://web111.secure-secure.co.uk/s...js/thickbox.js Line: 270 Which lead me to believe that my parent window has not got a name so i used window.name = "main"; in my parent and window.main.pageUpdate(); in the child and get same kind of error. Could someone please help me out! |
