JavaScript - Permanently Show An Object
Hello
I've been in a hick-up trying to edit a JS code to perform a certain task, or literally speaking; sit there permanently on the webpage? now this is the code: Code: $("#nav_search a").click(function(){
$("#toggle_background").slideUp();
$("#toggle_search").slideToggle();
$("#main_search").focus();
return false;
and i would like to know if there's a way to permanently display the object instead of having the user to click>show? thanks in advance Similar TutorialsGreetings Programmers. I'm a graphics artist by trade but I also dabble in web design. I registered to this forum because I need your help. I've been handed a web project at work - to build an intranet site. My coding skills in HTML are sufficient to get the job done and I can plug in some JS and trobleshoot where needed but I've hit a wall with regard to one seemingly simple piece of code - I can't find a script anywhere that will generate a radio button that will, once selected, stay that way pretty much forever...or until I delete the listing on the page where these buttons will sit. I realize this isn't the concept behind these buttons but I need it to function this way because I'd like it to serve as a quick visual notification that a given employee review has been completed. These reviews will remain online for up to several months because there will be three reviews per employee over the course of that time. The selected buttons will indicate the reviews that are complete while the unselected ones will indicate which ones are still pending. I'd like the various levels of management viewing this information to know instantly, via the buttons, where we are with these reviews. So, that's my question, can a radio button be scripted to stay selected indefinitely once it's been clicked on? Thank you in advance for any help. It's greatly appreciated. - Sgt. Spanky Hi, I would like to know how to add/remove items from listbox PERMANENTLY. Sad to say, all I have found are adding/removing items temporarily.

Please advise me on the problem. I need educating please. I have a javscript page (fred.js) that contains some variables and some code. I want to be able to change the variables (in particular an array) within fred.js on the server and store the new version of fred.js back on the server. I can write a php routine that stores the array in a MySQL table. Now I want to know how to write some code (and in what language) to read the MySQL table and update fred.js and store it back onto the Server. Can someone please tell me what language I should be using to do this (Ajax??) so that I can do some reading please. I could of course simply write some php code to read the table and pass the parameters to a js page and build the array as each person accesses the web page but this would be slow. Hence I would prefer to have the ability to update the js page and store it back onto the server. Hi, every time I try and alert: [ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ] it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert? Thanks. 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. 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. 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?? 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. 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. 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. How do I show the default icon for pdf, doc, etc... else show the image? Code: Show the default icon for pdf, doc, etc... else show image.

NOM NOM NOM! Hello, below you will find two objects, background and photo1, which I need help cleaning up a bit. This will eventually be imported using Json but for now during development it sits as is in my script. I need help with a couple things: - You will notice the 'val' property is identical in both objects. How can I move this into an outside function that each object can share? I'm having trouble bc I couldn't get 'this' to work outside of its current context. - Second, how can I restructure this so that I can instantiate a new object. So if I wanted to add a new layer I'd like to do something like importLayers.push[new Layer('photo2')] Code: var importLayers = {
background: {
layerType: 'background',
index: 0,
layerContent: {
content: function() {
return $(element).find('#background_Content');
},
width: 850,
height: 530,
xPos: 0,
yPos: -150,
skewX: 0,
skewY: 0,
angle: 0,
originX: function() { return (this.sWidth() / 2); },
originY: function() { return (this.sHeight() / 2); },
scaleX: 1,
scaleY: 1,
sWidth: function() { return this.width * this.scaleX; },
sHeight: function() { return this.height * this.scaleY; },
aspect: 0,
opacity: 100,
val: function(prop, val) {
switch(prop)
{
case 'width':
if(plugin.constrain)
this.scaleX = this.scaleY = val / this.width;
else
this.scaleX = val / this.width;
break;
case 'height':
if(plugin.constrain)
this.scaleY = this.scaleX = val / this.height;
else
this.scaleY = val / this.height;
break;
case 'angle':
this.angle = val;
}
buildTransformation(this, this.content());
}
},
},
photo1: {
layerType: 'photo',
index: 1,
layerContent: {
content: function() {
return $(element).find('#photo1_Content');
},
width: 1920,
height: 1280,
xPos: 0,
yPos: 0,
skewX: 0,
skewY: 0,
angle: 0,
originX: function() { return (this.sWidth() / 2); },

Greetings, I have a floating object that work find within my page. However, I would like to only show after a button is clicked. Any ideas how to do this. Thanks Code: function globals()
{
this.states = "";
}
now I can: Code: globals.states = .... how to extend first code to be able: Code: globals.states.something = .... ? Hey guys, I need to create a constructor for a computer object. This object must have three properties: speed, and mem_live mem_dead. Then I need to create a new object using this constructor and then have its properties displayed on the screen. Look at what I'm up to so far: Quote: function Computer(speed, mem_live, mem_dead) { this.speed = speed; this.mem_live = mem_live; this.mem_dead = mem_dead; } var computer1 = new Computer("4.0ghz", true, false); document.write(computer1.speed + " " + computer1.mem_live + " " + computer1.mem_dead); What am I doing wrong? It always just shows : 4.0ghz, true, false Hello awesome coders! I am here in need of your help. I have a site with a lot of videos, from different sources, in different sizes, only thing they have in common is <div id="player">. Due do different sources, each video player is different. Some have embed code, some have object, some have iframe, some have both/all. Is it possible to create a script that will: Change the height and width of object, embed, iframe within the div. Is there another way to resolve this issue without changing all video code manually. |
