JavaScript - Javascript Date Object

Not 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.

I am rather new to javascript programming and not sure if this is the best approach to handle a problem.
In setting up a simple image display that can later be modified to a rotator, I am using the following code

window.document.display1.src = image1.src;

now the question is when modifying that to be more dynamic, where display1,display2,.. can refer to a different image (or set).


var Image = "image";
var Display = "display";
for (i=1; i<n; i++){
window.document.this[Display+i].src = this[Image+i].src;
}
I know the right hand side of the equation is working (alert() displays the right soure), but the problem is the left hand side. I guess because of me not fully understanding the way objects work. why this[] works on the right and not on the left? and how do I resolve it?
All your comments, and a push in right direction are appreciated.

I am doing my homework for my class, and I don't usually ask for this much help because I get most of them done by myself. However, I am having a really hard time to understand this time. I have lots lots of questions...I tried to follow the instructions that I got from my professor, but it seems not clear enough to me...
If anyone can fix or add on my codes, I will be really really appreciated....and here is the instructions and my codes..

If the form validates, instead of returning true, call the GetValues() function followed by the DisplayOutput() function.
so, I changed result true to calling functions like this,
Code:

if (blnError == true){
	return false;
	}  
	else {
	   DisplayOutput();
	   GetValues();
	}

In the .js file, create a PortraitOrder class using the following specifications
Properties: portrait, copies, size, buyer
Method: CalculateCost () -- determines the size (radio buttons) and then mutiplies the related cost by the number of copies
Code:

function PortraitOrder(){
	var cost;
	this.copies = "";
	this.portrait = "";
	this.size = "";
	this.buyer = "";
	var CalculateCost = {
    	   met1 : function () {
		if(size == 0){
		   cost = this.copies * 10
    		}
		else if(size ==1){
		   cost = this.copies * 20
		}
		else if(size ==2){
		   cost = this.copies * 10
		}
		else if(size ==3){
		   cost = this.copies * 30
		}
		else{
		   cost = this.copies * 20
		}
	   }
	}	   	
}

Create a new instance of the class named portraits as a global variable in the ,js file -" I don't see why I need this. So I did not create
Create a GetValues() function that will
retrieve the values from the form fields (document.forms[0].element.value) and assign them the properties of the instance of the PortraitOrder class.
use a for loop to retrieve the value from the radio buttons
use the prototype property to add a new property named email to the instance of the class
retrieve the value from the form field and assign it to the new email property
Code:

function GetValue(){
	this.copies = document.forms[0].Copies.value;
	this.buyer = document.forms[0].Buyer.value;
	var file = document.getElementsByName('Filename');
	for(var i = 0; i < file.length; i++){
    	if(file[i].checked){
       	 this.portrait = file[i].value;
    	}
	}
	
	var sizes = document.getElementsByName('Size');
	for(var i = 0; i < sizes.length; i++){
    	if(sizes[i].checked){
       	  this.size = sizes[i].value;
    	}
	}

	GetValue.prototype.email = document.forms[0].Email.value;
}

Create a DisplayOutput() function that
calls the CalculateCost () method for the current instance of the class.
displays the image using the value from the portrait property which contains the filename. Be sure to include height and width (and that would be why all of the images had to be the same dimension. These values can be hardcoded. The filename, however, may NOT be hard coded.. it must use the object.property format.
displays the buyer, email, copies, size, and cost using the object.property format (document.forms[0].element.value is not permitted)
The cost must be formatted as ##.## where # represents a number (Hint: Use a method of the Number class). It is NOT okay just to concatenate .00 to then end of the cost.
Code:

function DisplayOutput(){
	CalculateCost.met1();
	document.write("buyer: " + this.buyer);
	document.write("Email: " + email);
	document.write("Portrait: " + this.portrait);
	document.write("Copies: " + this.copies);
	document.write("Cost: " + "$"+cost.toFixed(2));
	document.write("Thank you");
}

The order form must include the site's header and footer and coordinate with the rest of the site.
There is no form processing file, everything is done in the .js file.

You may think like, this is horrible codes. And yes, it is. I know probably this is totally odd. This is why I came here for ask help. Also, I spent days to tried, but I could not get any idea...Anyone please help me on this?

I'm writing a script in javascript(actually a chrome extension) and I need an object that I can write to it like this(sorry, don't know how to explain it better) and then I convert it to string with format of json.

Code:

id[129].weekDay[6].hour[23] = 0

Here, id is an array, that each element in it contain another array(weeksDay) and in that array each contain another array(hour).
The id indices are unlimited, for weekDay 7 and hour 24.

I searched in google but i couldn't find what I wanted. Actually don't know the best keyword to search.(objects in arrays?)

I don't know what exactly it is called, I can write it's declaration in VB.NET if that helps you.

Hi,

I am trying to create an array to pass to JQuery, but after several hours of trying, am falling over. I am trying to use Ajax to populate the javascript FullCalendar.

I am trying to pass an arry to the following property:

This works:

$('#calendar').fullCalendar({
events: [{"id":1112,"title":"Event1","start":"2009-10-10"},{"id":222,"title":"Event2","start":"2009-10-20","end":"2009-10-22"}]
};

something like:

$('#calendar').fullCalendar({
events: MyJSArray()
};

I will be using AJAX to populate MyJSArray().

I have tried the likes of: MyJSArray = new array("id"=>112,"title"=>"Event1", etc);
But no joy

I don't know how to get a javascript array into that format. I have my database values, but I need to put them into a format that the "Event" will accept.


I have used PHP and arrays fine, but coming to grips with JS arrays,etc are a bit finiky at the moment.

I am a little stuck, any help or points in the right direction will be much appreciated.

Thanks Blueevo.

I have several list items in an html document. Each list item has an anchor tag and each anchor has an 'onmouseover' event.

Is it possible to get the containing object for the event upon the mouseover?

Hi i am confused in one topic and need help,

I have a javascript array containing objects like;
Object values are ordered as Type, Amount and count.

Object 1 => ("A" , 100 ,10)
Object 2 => ("C" , 50 ,10)
Object 3 => ("A" , 100 ,20)
Object 4 => ("B" , 200 ,10)
Object 5 => ("A" , 10 ,10)
Object 6 => ("B" , 100 ,10)
Object 7 => ("C" , 100 ,5)
Object 8 => ("C" , 50 ,5)

In the end i want to group these objects like ;

("A" , 100,30) (Note : 30 = 20 +10)
("A" , 10,10)


("B" , 200,10)
("B" , 100,10)


("C" , 100,5)
("C" , 50,15) 15 = 10 + 5


How can i do this in javascript, note that the new types will be added to this array ?

Hi,

I'm looking for some help, or perhaps an explaination in regards to "click & rotate" an image using your cursor with Javascript. I've seen this a couple of times on various websites and I'm wondering how difficult/expensive it is to develop such an image.

I own a clothing company and what I'm looking to do is to create images on my website of a product in which the customer can click on and "rotate" to see a 360 degree view of the product. Think autocad to a degree...

Is Javascript the best language to pursue for this function? I'm quite new to this department, so any help/advice is greatly appreciated.

Hi all,

Have problem from getting data of JavaScript Object ie. Associative Array.

Code:

var a, table1
a = new ActiveXObject("MyProgID");  a.GetDataFromExcel("C:\\Users\\myFolder\\Desktop\\test.xls","Sheet1")
a.Generate()  
table1 = a.writeInTable();

Here writeInTable function returns a 2D Object array from DLL written in VB.Net. So I got the Object to table1.
But from table1, I can't access the values but its there. table1 shows values as in this image(Image Attached.)



Actually, I tried many ways like
tab(0)(0)
tab[0][0]
tab["0"]
tab.(0).(0)
tab.[0].[0]
Also with toArray(), (new VBArray(tab)).toArray()....


I don't know what I am wrong..Can anyone help me on this?

Thanks...

I was going through an article on JavaScript objects on "http://www.howtocreate.co.uk/tutorials/javascript/javascriptobject" and there I read

Quote:
Intrinsic objects - variable types with constructors.

* Array
* Boolean
* Date
* Function
* Image
* Number
* Object
* Option
* Regular Expression
* String
does it mean that, whenever I want to use any of these objects, I have to create it using new and only then I can use its properties or methods ?

1) There are other objects like document, history, location, navigator, parent and screen. If objects which need to be created using constructor are called intrinsic objects , then what are other objects which can be used without constructor are called as ?

Array, Boolean, Image, Date etc all start with capital letter. While document, history, navigator etc start with lower case letter. Why is that ? Is there any difference between objects that start with upper case and those start with lower case ? Are they known by different names ?

Thanks

Hi,

Hi All,
I am using javascript to get the number of rows in my HTML Table by using below code:
Code:

var oRows = document.getElementById("HTMLTable").getElementsByTagName('tr');
var iRowCount = oRows.length;

Later I am using iRowcount in the FOR loop further in my code as below:

Code:

for(k=1; k<=iRowCount; k++)  {
............................
rest of code ...........
............................
}

This piece of code is working fine (i.e. it handles the functionalities which is needed) but it also opens a new browser window with the error message "Object Required".I have really no idead why this is happening.Can anyone suggest me the reason for this?

Thanks in advance.
