I am trying to find a format for a string that could be used to instantiate a Date object which would include only a month and a year.I can't find documentation on what formats of dates are accepted.
View 6 RepliesIs there any way at all to create a new template object that inherits from the built in Date object so as to be able to add new methods to that child object without adding them to the built in Date object? I've tried everything I can think of and as far as I can tell it keeps referencing the Date function instead of the Date object and so doesn't work.
View 3 Replies View RelatedI'm working on a project that requires me to send stuff through an AJAX $_GET request to a PHP page which then echoes a string which then is fed back to the form on the first page.
So the GET url looks something like this:
Code:
dataminer.php?question=kassasumma&q=500&kale=10%&nro=6
I have tried to escape that URL with various escaping methods including
Code:
escape()
[Code]....
but, with no luck. The server keeps giving me a 406 Not Acceptable and it's because of the percentage sign (which is essential) in the url.
placement of the return in the following code:
var abc;
try{
//there can possibly be 1 or more answers;
abc = getAnAnswerFromPossibleAnswers("type","key");
[Code].....
One person says the return should go inside the try because otherwise during runtime a null pointer exception (NPE) can be thrown. The other says they tested and never got an NPE - even if the value didn't exist, abc[0] returned an empty object (the test showed it returning empty curly braces).
Must the return go inside the try or is it ok to be outside as in the above snippet?
question: if you want a link which simply runs a js function is it acceptable to have no href? the problem with this is the cursor doesnt change when you hover over, but if you put # as the href it jumps to the top of the screen which is sometimes unacceptable. what it the best solution to this? granted you could do event handling behind the scenes and just intercept the clicks and prevent the href from going anywhere, but sometimes you just want to stick an onclick on the anchor tag!
View 5 Replies View RelatedI'm working on a very Javascript heavy application, and we've set up a number of different Objects to handle the data on the page. Very often, we'll need to send all of the data from these objects to PHP. Right now, we're using JSON.stringify. Are there any issues with this? It seem's like it does exactly what we need, but are there any downsides?

According to the Safari browser the world began on "Fri Dec 13 1901 15:45:52 GMT-0500", but I need to be able to get around this limitation.
I am interested in dates from 1500 to 1901, as far as I can determine, there are 14 possible calendar variations.
Year starts on Sun, Mon..... Leap year starts on Sun, Mon..
I can label these early year "types" as a number between 0 and 13.
Let's say 2005 is type 5, and that 1655 is too. (In both years Jan 1 falls on a Saturday)
I'm trying to create a function that will identify the "type" of year.
function getYearType(year){
return Number // number between 0 and 13
}
Am i breaking any rules when I loop dates like
// Determine Memorial Day
intFlag = 0;
memDayHol = new Date (currentYear, 4, 31);
while (intFlag == 0) {
if (memDayHol.getDay() == 1) {intFlag =1;}
else {memDayHol = memDayHol - 1;}
}
I can find no docs that one can use the '+' operator directly on a date
object, and it assumes adding/subtracting a day(s). Is this deprecated
code?
How to extend the constructor for the date object of the javasccript so that whenever a call is made to the constructor, I want to perform a particular action? Basically how to define wrappers for default javascript methods or objects like Date() so that I can perform some action and then invoke the original method? So basically if I have something like var a = new Date(); I want it to (say) alert the value of the date everything Date() is called and then execute the default date constructor.

I was wondering how you would create a javascript Date object from an ISO8601 string? We have done this successfully in FF4, but not IE.
If we try the following in FF4 it works:
alert(new Date("20091107T12:15:00))
In IE it returns:
'NaN'
What would be the Date standard used in JavaScript and AJAX from the server to the client? We were thinking about using UTC
Is it possible to convert a String of date like 12/25/2005 01:00PM to a Date object?
View 14 Replies View RelatedI have a question about what the most certain method to obtain the correct UTC time in javascript is.On my forum, there is a countdown clock, that should show the same amount, wherever the user is located. I use UTC in javascript to get the current time, but I have trouble getting consistent results.I have tried two methods:Method 1:
Code:

var localTime = d.getTime();

I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.
What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....
In the below, I would expect this to return the number of milliseconds since the epoch. Instead, it's generating a massive negative number. I presume I've gone wrong with the set[Blah] methods.
javascript Code:
var date_text = '2009-03-06 12:00:00';
var d_tried = new Date();
d_tried.setYear(parseInt(date_text.substr(0,3)));
d_tried.setMonth(parseInt(date_text.substr(5,6)));
d_tried.setDate(parseInt(date_text.substr(8,9)));
[Code]....
I was wondering if it is true that the Date object gets its date from the user's local time, if so, could the user "hack" the time by adjusting his local time?

I am facing issue in below code for Brisilia time zone.(GMT-3). Issue comes in October month only. It is going tobig loop. I am not getting how Date object is behaving here.
[Code]...
I was working on Date() object of javascript. When I write:
today=new Date();
year=today.getYear();
month=today.getMonth();
day=today.getDay();
Here everything was correct but when I print month then I got currentmonth-1 that if the currentmonth is 5 then t get 4. If the current month is 07 then I get 06. At last I worked by adding 1 with month like month+1.
I am trying to use my date Object function to get the date from the comp but my variables in my function are coming up undefined.
Here is my function:
function displayTime() {
var currentTime, hour, minute, second, range, m, s
currentTime = new Date()
var hourInt = currentTime.getHours()
var minuteInt = currentTime.getMinutes()
var secondInt = currentTime.getSeconds()
if (hourInt > 12) {
range = "PM"
hourInt -= 12
} else {
range = "AM"
}
hour = String(hourInt)
if (minuteInt < 10) {
m = String(0) + String(minuteInt)
} minute = m
if (secondInt < 10) {
s = String(0) + String(secondInt)
} second = s
document.timeForm.timeBox.value = hour + ":" + minute + ":" + second + " " + range
alert(hour + ":" + minute + ":" + second + " " + range)
Well, this is acutally a couple different scripts. First is the custom date object myDate which retrieves pretty much every value that you'd need from a date and sets it as a property. If no argument is supplied, the current time and date is used. If you do supply an argument, you can send an existing javascript Date object, or a string that is compatible with declaring a normal javascript Date object.
The 2nd part of this script is the method getDate (and some accompanying String methods) that allow you to retrieve the date as a string by passing it a format string just like the PHP date() (http://www.php.net/manual/en/function.date.php) function accepts. The code posted below includes sufficient (I think) examples to help you understand what is going on. You will notice that I didn't duplicate EVERY code over from PHP, and a few are slightly different. Those that I left out I felt weren't very necessary, or I didn't feel like doing the algorithm for them :D.
Both myDateObj.getDate() and PHP's date() allow you to include text into the string that you don't want parsed, but each handles it differently. In PHP, you need to escape characters normally with a backslash. For getDate you need to proceed each character with a pipe "|". So, instead of$dateStr = date("Day z");as it would be in PHP, you would usevar d = new myDate();
var dateStr = d.getDate("D|a|y| z");There are more examples of how this works below.
Note: There is also a nice arrayReplace() method for strings that is handy for doing multiple replace() operations all at once, so I guess this is really like 3 handy scripts ;)

I have a start date and end date text boxs. What I would like to achieve is when a submit button is clicked all the available dates between start and end dates should be displayed together with 3 check boxes next to each date (please see below).

I have added a booking form to a website with belongs to fastbooking.You can see a temporary website here. http:[url]....It works perfectly fine in Mozilla Firefox, Google Chrome, Opera and Safari but it does not load on Internet Explorer.On the other browsers the form loads todays date and the year is generated but on IE the date stays on 01-01 and no year is generated.I'm using wordpress as a cms.I think the code that is not loading is <body onLoad='start();'>But I'm not sure. The code of the year is
<select name='fromyear' class="input" onChange='update_departure();'>
<option value="0"></option>
</select> But since it's no just the year I assume its the onload code.
I tried to add the onload to the header function like this
<body onLoad='start();' <?php if(function_exists('body_class')) body_class(); ?>>
So now wordpress generates the following code when it loads the page
<body onLoad='start();' class="home page page-id-6 page-template page-template-default logged-in">
But sadly the date still does no load on Internet Explorer.
