JavaScript - Primitive To Object Conversion (workaround?)

I can't get any info from Firebug except that one line, uncaught exception [object Object]. The code fully worked, then I needed to make it dynamically create Sortables from the scriptaculous library based on how many X were in a table in my database, which I've done, and I'm thinking it may be a simple slight parse error of some type, I'm not too good with Javascript, because now my script barely works. I've double checked the script's source code, the PHP variables are exactly what they should be.

Code:

print<<<HERE
               Sortable.create('sortlist$box', { tag: 'img', overlap:'horizontal',constraint:false, containment: $list, dropOnEmpty: true, 
                onChange: function(item) {
                    var list = Sortable.options(item).element;
                    
                    if(changeEffect) changeEffect.cancel();
                    changeEffect = new Effect.Highlight('changeNotification', {restoreColor:"transparent" });
                },
            
            
            
            onDrop: function(item) {
            var thing=Sortable.options(item).element.identify();
            
            var anchors = document.getElementById(thing).childNodes.length-2;
            
            if(anchors > 20){
            alert('This box had 20 creatures in it already, your last action has not been saved.');
            window.location.reload();
            }
            else{
            
            new Ajax.Request("saveImageOrder.php", {
                        method: "post",
                        parameters: { data: Sortable.serialize("sortlist$box") }
                    });
               }   
}               
            });
               
HERE;
$box++;

}
?>
          
        });
    </script>

if you solve this I'll send ya $10 via paypal

I created a method for displaying an object's properties:

Code:

renderfunction 	= false;

function showProperty (object, property)
{
	document.write  ('<td class="type">' + (typeof object[property])  + '</td>' 
					+ '<td class="name">' + property + '</td>');
	
	document.writeln('<td class="value">' + 
						(
								(typeof object[property] != 'function')
								? object[property]
								:(
										(property != 'showProperties')
										? (
											renderfunction
											? object[property]()
											: ('<span class="self">NOT RENDERED</span>')
											)
										: ('<span class="self">THIS</span>')
								 )
						) 
					+ '</td>');

	
	document.writeln('<td class="hasOwnProperty" >'  
							+ (
									object.hasOwnProperty(property)
									? "Local"
									: "Inherited"
								)
					 	+ '</td>');

	if (typeof object[property] == 'function')
	{
		document.writeln ('<td class="function">' + object[property] + '</td>');
	}
	else
	{
		document.writeln ('<td class="function"> </td>');
	}

}

As long as renderfunction = false, the object is fine coming out of this function.

However, if I change renderfunction to true, all my properties become undefined.

Why isn't this working as I expect it to?

How should I fix it?

Thanks in advance,

-Brian.

Hello together!

I generate html code with jsp. In that jsp there a several framesets and frames. And yes i know, frames are not really up to date but it's an old program and i have to deal with it now. Anyway, in the top frameset i have an onload attribute like onload="load()".

In the function load i want to access the Element.prototype object. But unfortunately typeof Element gives me "undefined". So i looked a little deeper and found that window.toString() gives me "[object]" and not as expected "[object window]" so somehow my window doesn't know that its construcor is Window. window.construcor is "undefined" as well. And i don't have access to the Element object. I really don't know where the error could be. When the page is loaded and i access the same window over the console, then everything is right. But in my function a can't get access to the objects i need.

I also don't know what part of the code could be useful to post here, but maybe someone had a similar problem before? i should say that this problem only occurs in IE8. In IE9 it works perfectly.

Has anyone any idea??

Hi all,

I'm stumped on finding a way in javascript to create an object factory whose instances are also object factories. In short I want something like that below, but no joy ... any clues?


Code:

function createClass () {
	return new createClass()
	function createClass() {
		return new createInstance ()
		function createInstance () {
			//Default properties, values and methods which might later be extended
		}
	}
}

var createDoor = createClass();
var door1 = createDoor();
var door2 = createDoor();

var createChair = createClass();
var chair1 = createChair ();
var chair2 = createChair ();

I'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...

Problem is I'm not sure how to properly access those properties... see below please.

<script>

//This is an example of a problem im having in my own code...
//I want to access the name of the object within the links array wintin the object...

var objA = {name: "Object A", links: [objB, objC]};
var objB = {name: "Object B", links: [objC, objD, objE]};
var objC = {name: "Object C", links: [objB]};
var objD = {name: "Object D", links: [objE]};
var objE = {name: "Object E", links: [objD]};

//ex: I want to access the name of Object A's first link...
console.log(objA.links[0].name);

</script>

I'm hoping to get "Object B"...
But instead I get: TypeError: Result of expression 'objA.links[0]' [undefined] is not an object.
Is there another way around this? Any thoughts are appreciated.

Hi, am new to Java, Jquery and Java Script and I am finding my way through recently...

I have this HTML code

Code:

<html:text styleClass="ui-inputText" size="12" styleId="fromDate" property="fromDate" name="HomePageForm" readonly="readonly" />
<script>
initDatePicker("fromDate");
</script>

I want to perform this action using JS.
This will create a text-box with a calender affixed to it if used in Plain HTML...


This is the initdatepicker function

Code:

function initDatePicker(dateFieldId){
var format = '<%=ctx.getDateFormat()%>';
if (format == "yyyy-MM-dd"){
format= "yy-mm-dd";
}else if (format == "MM/dd/yyyy"){
format= "mm/dd/yy";
}else if (format == "dd-MMM-yyyy"){
format= "dd-M-yy"
}
$("#"+dateFieldId).datepicker({
showOn: 'button',
buttonImage: 'include/images/icons/calendar.png',
buttonImageOnly: true,
changeMonth: false,
changeYear: false,
buttonText: 'Select date' ,
dateFormat: format
});
}

I have done a few things, but, could not get the result I need...

Code:

cellIndex++;
var cellObj=$('#genericRules tr:eq('+index+') td:eq('+cellIndex+')');
cellObj.html('');
var table = document.getElementById("genericRules");
var rowElem = table.rows[index];
var cell = rowElem.insertCell(3);
var txtInp = getTextField(indexName,index,'8');
cell.appendChild(txtInp);
var dateImg = getImage(index);
cell.appendChild(dateImg);
cell.align="center";
initDatePicker(indexName + '['+index+'].'+name+'from');

function getTextField(indexName, index, size) { //, maxlength
  var txtInp = document.createElement('input');
  txtInp.setAttribute('type', 'text');
  txtInp.setAttribute('class', 'ui-inputText');
  txtInp.setAttribute('indexed', 'true');
  txtInp.setAttribute('name', indexName + '['+index+'].'+name+'from');
  txtInp.setAttribute('id', indexName + '['+index+'].'+name+'from');
  txtInp.setAttribute('size',size);
  txtInp.className = "ui-inputText";
  txtInp.name=indexName+'['+index+'].'+name;
  txtInp.indexed ='true';
  return txtInp;
}


function getImage(index){
var image = document.createElement("img");

image.src = "<%=request.getContextPath()%>/include/images/icons/calendar.png";

image.setAttribute('class', 'inputCalendar');
image.className = "inputCalendar";
image.name = "imgDatevalue"+index;
image.id = "imgDatevalue"+index;
return image;
	}

My application is now showing me the image but, am not able to get the calender when i click on it..

I need help on this thing...
Please try to provide me with soem intel...

Quote:
menu: function( a, b ) {
$( b ).observe( 'click', function( event ) {
event.stop();
if( $( a ).visible() ) {
$( a ).hide();
$( b ).removeClassName( 'selected' );
document.stopObserving( 'click' );
} else {
$( a ).show();
$( b ).addClassName( 'selected' );
document.observe( 'click', function( e ) {
if( e.target.id != a && e.target.id != b && !Element.descendantOf( e.target, $( a ) ) ) {
$( a ).hide();
$( b ).removeClassName( 'selected' );
document.stopObserving( 'click' );
}
});
}
});

$$( '#' + b + ' > a' ).each( function( element ) {
element.observe( 'click', function( event ) {
$( a ).hide();
$( b ).removeClassName( 'selected' );
document.stopObserving( 'click' );
});
});
}
This work's perfrect accept when i use it with others on the menu it leaves the other ones open, how do i get it to close the open one when i open a new menu..

Thanks.

Hello.

Is there any way to get the variable name of an object from inside the object?

E.g.

PHP Code:
function Bla(){

    this.write = function(){
    document.write(<objectname>);

    }

}

obj1 = new Bla();
obj1.write(); //Outputs obj1 



Here is my script:

PHP Code:
function myTimer(seconds, obj){
    this.seconds = seconds;
    this.obj = obj;
    this.startTimer = function(){
        if(this.seconds>0){
            this.seconds--;
            this.obj.innerHTML = this.seconds;
            this.timer = setTimeout("Timer.start()",1000);
        }
    }

}
Timer = new Timer(10, obj);
Timer.startTimer(); 



Now the problem is that the variable that contains the object must be named "Timer".

This way I cannot create new timer objects with different variable names

I have tried:
this.timer = setTimeout("this.start()",1000);
but it doesn't work.

That's why it would be good to detect the variable name and instead use something like this:
this.timer = setTimeout(varname+".start()",1000);

I would rather not have to pass the variable name through a parameter like this:
Timer1 = new Timer(10, obj, "Timer1");

Thanks in advance.

Dear All,
On my HTML page, I am trying to use as a snippet the script for automatic currency conversion. It is well known that exchange rates between currency are being changed very often (most of times even daily) and I don't want to republish either page with script or entire website every time the exchange rate changes. For website design I am using xsitepro software because I don't know programming.
So what I would like to have on specific page of website is something similar to table (if anyone has any better recommendation than using a table, please share). In this table I would like to state prices of my services. Primary currency is only one. So in this column, the numbers shouldn't be changed unless I want to change the prices (and of course therefore republish the website, no need to republish sitemap). In the rest of the columns the numbers should be changed immediately, without needing to republish anything (thats the point of the script) and also rounded to each 5. What I mean with ''each 5'' is shown on few of the following random chosen examples (1500):

1500.03 is rounded to 1500
1500.30 is rounded to 1500
1500.50 is rounded to 1500
1502.49 is rounded to 1500
1502.50 is rounded to 1505 (!)
1504.99 is rounded to 1505
1505.01 is rounded to 1505
1507.49 is rounded to 1505
1507.50 is rounded to 1510

and so on. Idea is to prevent from getting coins. So the break point is on 2.50, 7.50, 12.50, 17.50, 22.50, 27.50 and so on. Not sure how to mathematically describe this. Hopefully I was understandable.

I want to have in the columns only the currencies that I am willing to accept if potential client cannot change the currency to my primary one (given in second most left column) in his local exchange office. But I repeat that what Im trying to do is having automatically and immediately updated numerical values on particular HTML page based on most recent exchange rates (of course trustful source is needed).
Since I don't know programming, I did some research on google and discovered this:

http://coinmill.com/webmaster_options.html

The downer script on the right side looks ok but its not even close to what I need due to five reasons:
- it is being converted outside the table
- with such way i cannot clearly show which currency is primary (prefered) one
- conversion is being done to only one other currency at the same time
- no rounding to ''each 5''
- unknown source (and therefore untrustful one) of updating most recent exchange rates

Table such as this one:

http://www.x-rates.com/

looks great but still not meeting my requirements. I would like to replace flags in the left column with ''service 1'', ''service 2'', ''product 1'' etc. Also I have no idea how rounding could be done.
So at the end I would end up with something like (here Im showing only two ''still willing to accept'' currencies just to show an example):


Currency:Euro Currency:American Dollar Currency:Japanese Yen
Service1 500 670 51535
Service2 400 535 41228
Service3 200 265 20614

Top left corner as it is on x-rates.com would be even better.

note: when I previewed my post before submitting, I noticed that the forum doesn't let me make so much spaces but I think those numbers are still understandable where do they belong.

Any help would be muuuuuch appricated

Hi all,

First of all thanks for everyone who responds to me. I appreciate it.

Here is my problem.


I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable.

The problem is as follows:

When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have. Thanks in advance for your help.


<html>
<script type = "text/javascript">

function square(form)
{


var test = form.value1.value;
window.alert(+test);

var point = document.test.value1.value;
pointcon = point.toString();

window.alert("nice");
window.alert(+pointcon);

var point2 = eval(document.test.value2.value);

var point3 = point + point2;
alert(point3);

}

</script>



<head>
<body>
<form name = "test">
First name: <input type="text" name = "value1" value1 = ""/><br />
Last name: <input type="text" name = "value2" value2 = ""/>
<input type = "button" value = "Submit" onClick="square(this.form)"/>
</form>
</body>

</html>

I would like to compare dates in the format used in twitter, which is this:
Wed Apr 08 14:30:10 +0000 2009

How do I do this? Do I need to convert to a timestamp first, and if so, how do I do this?

Hi,

Please bear with me as I have zero knowledge of programming, or even if this is the right way to do this.

I use a website that has (i believe) Javascript on that uses some maths, and I am looking to convert this webpage into excel...

I wonder if someone could give me a pointer to convert the attached code into the excel format, or even just to highlight where the maths is so i can continue myself!

Code:

script is too long, so ive attached as a zip

Hey everyone, I have a slight problem with my program and am in need of some help. I am writing a program that will take user input and convert the 8 digits the user enters (the 0's and 1's) and converts them into an integer between 0 and 255. It is a very simple program but I am still having some errors :/ If anyone could take a look at the program and get back to me, it would be very helpful!


Code:

	static int binaryValue = Integer.parseInt(userInput);		//Parses the user's input into an integer
	
	
	public static void convert()		//Method to convert the user's input into a number
	{
		
		char firstNumber = userInput.charAt(0);		//Reads the eight numbers the user enters
		char secondNumber = userInput.charAt(1);
		char thirdNumber = userInput.charAt(2);
		char fourthNumber = userInput.charAt(3);
		char fifthNumber = userInput.charAt(4);
		char sixthNumber = userInput.charAt(5);
		char seventhNumber = userInput.charAt(6);
		char eigthNumber = userInput.charAt(7);
		
		System.out.print(firstNumber);		//Just to check to see if the correct numbers are being read from the JOptionPane

I am trying to fix a problem that I have with my JavaScript assignment for class. The code I have so far is beneath. I ran FireBug on it, and came back with "missing ) after argument list on Line 24"

Code:

// declare a variable
var c
var f

// get variable's value
f = parseFloat(document.getElementById('c').1.8 * c + 32)
}
</SCRIPT>

Code:
