JavaScript - Remove A Class And Edit An Object

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'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.

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 ();

Hello,
I am new with Javascript and running into this problem that I don't understand.

I define a base class that only contains an array "elements", and a derived class that contains nothing more (for simplicity):

Code:

  function baseClass() {
     this.elements = new Array;
  }

  function derivedClass() {
  }
  derivedClass.prototype = new baseClass;

Then I create two instances of the derived class, and add two elements in each:

Code:

   a = new derivedClass();
   a.elements.push("A");
   a.elements.push("B");

   b = new derivedClass();
   b.elements.push("C");
   b.elements.push("D");

When I examine the contents of these arrays, I see that both a.elements and b.elements contain {"A","B","C","D"} ! I.e. as if the two arrays are in fact the same array! But these are two separate instances of the class, I expect two separate arrays.

Note that if instead I use the base class:

Code:

   a = new baseClass();
   a.elements.push("A");
   a.elements.push("B");

   b = new baseClass();
   b.elements.push("C");
   b.elements.push("D");

then I get a.elements = {"A","B"} and b.elements = {"C","D"}, as I would expect.

Could someone explain to me the problem with using the derived class?

Thank you,
Stephanos

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.

I am trying to troubleshoot my javascript function below.

Code:

<script type="text/javascript">
function txtboxfill(fillobj) {
    var rChar=String.fromCharCode(13);	
    var myVal = "To: " + this.form.to.value + rChar;
    myVal = myVal + "From: " + this.form.from.value + rChar;
    myVal = myVal + "Subj: " + this.form.subj.value + rChar + rChar;
    myVal = myVal + "Message: ";
    fillobj.value = myVal;
}
</script>

Then I have a text box input field with an Code:

<input type="text" id="tp" name="to" size="34" class="totext" onkeyup="txtboxfill(this.form.msg_area);">

and when I enter text in this field it gives me a 'this.form.to' is null or not an object and does not populate the textarea. BTW, msg_area is the id of my textarea.

Thank you.

Hello,

I am having some issues. I have a loading bar, created with CSS. Although, I want to fill the loading bar (Increasing the width) with javascript (onload)

Is this possible? Thanks.

This website details how to make a gallery with javascript. http://monc.se/kitchen/80/lightweigh...ith-thumbnails My problem here is that instead of a cropped image in the thumbnails, I would like a re sized image. This is the CSS and javascript code. Code:

/* begin gallery styling */
#jgal { list-style: none; width: 200px; }

#jgal li.active img { display: block; }
#jgal li.active, #jgal li:hover { outline-color: #bbb; opacity: .99 /* safari bug */ }

            obj.attachEvent("on"+type, obj[type+fn]);
        }
    }
}

gal.addEvent(window,'load', function() {
    gal.init();
});
    </script>

Hi there, I have a listbox and an Edit button. The user will need to click on the email address in the listbox before clicking on the button to edit. But then, the email address will be displayed on the prompt box's textbox, and even without editing it, the user can get scot-free.

I would want to remove the email address on the prompt box's textbox, and also to check for null entries. If it is null, it will display an alert message. Else, it will check if it is a valid email address.

My code is as follow:



Code:

function editItem()
{
    var listbox = document.getElementById('listBox'); // listbox control id
    var newValue = lst.value;
    if(newValue != "")
    {
        var newItem = prompt("Enter the new email address",newValue);
        if(newItem == "")
        {   
            alert("Please key in an email address into the textbox.");
            return false;
        }
        
        else
        {
            listbox.options[listbox.selectedIndex] = new Option(newItem,newItem,false,false);
            return false;
            arrTexts = new Array();
            
            validRegExp =/^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/

            // search email text for regular exp matches
            if (arrTexts.value.search(validRegExp) ==-1 )
            {
              alert('A valid e-mail address is required.\nPlease try again.');
              return false;
            }
            
            else
            {
                for(i=0; i<listbox.length; i++) 
                {
                    arrTexts[i] = lst.options[i].text;
                }

                arrTexts.sort();

                for(i=0; i<listbox.length; i++) 
                {
                    listbox.options[i].text = arrTexts[i];
                    listbox.options[i].value = arrTexts[i];
                }                    
            }
        }
    }
    else
    {
        alert('Select Item From The List To Edit ');
    }
}
