JavaScript - Accessing And Changing Two Items In An Object
So I'm pretty much new to JS, and I'm trying to write something, and I'm having a problem.
It's a color picker. So I have an object that defines the default color, and then when the color is updated, the different css classes need to be updated as well. So here's what I was trying to do Code:
var colorPicker = {
mainColor: "red",
backgroundColor: this.mainColor + "bkgd",
}
So problem 1 is I keep getting "undefined" returned for "this.mainColor". If I use colorPicker.mainColor, it hasn't been created yet so it throws an error. Problem two is if I update mainColor from another function, say to make mainColor = "green", then backgroundColor doesn't automatically update. Any help is appreciated. Thanks Similar TutorialsI'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, I have a multi-dimensional object, derived from JSON returned by the Foursquare API. The object has the following structure (as printed using a print_r type method from http://www.openjs.com/scripts/others...hp_print_r.php PHP Code: '0' 'id' => "27110xxx" 'created' => "Sun, 11 Apr 10 15:09:45 +0000" 'timezone' => "America/New_York" 'user' ... 'id' => "48xxx" 'firstname' => "Barry" 'lastname' => "xxx" 'photo' => "http://playfoursquare.s3.amazonaws.com/userpix_thumbs/4abb5bxxxxxx.jpg" 'gender' => "male" 'display' => "xxxx. @ [off the grid]" '1' ... 'id' => "2538xxxx" 'created' => "Wed, 07 Apr 10 13:24:41 +0000" 'timezone' => "Europe/London" Could anyone tell me the best way to access its elements? I have this so far which gets the required values, but I want to preserve the order ie. get the data from the first element in the object first, then move to the next - each element represents a user so I want to keep their data separate. PHP Code: /* This is a custom function which has the same function as print_r */ function dump(arr,level) { var firstName, lastname, geolat, geolong, photo; var dumped_text = ""; if(!level) level = 0; //The padding given at the beginning of the line. var level_padding = " "; for(var j = 0; j < level + 1; j++) level_padding += " "; if(typeof(arr) == 'object') { //Array/Hashes/Objects for(var item in arr) { var value = arr[item]; if(typeof(value) == 'object') { //If it is an array, dumped_text += level_padding + "'" + item + "'\n"; dumped_text += dump(value,level + 1); } else { dumped_text += level_padding + "'" + item + "' => \"" + value + "\"\n"; } if (item == 'firstname') { firstname = value; document.write("First name: " + firstname + "<br />"); document.write(item); } if (item == 'lastname') { lastname = value; document.write("Last name: " + lastname + "<br />"); document.write(item); } if (item == 'geolat') { geolat = value; document.write("Latitude: " + geolat + "<br />"); document.write(item); } if (item == 'geolong') { geolong = value; document.write("Longitude: " + geolong + "<br />"); document.write(item); } } } else { //Stings/Chars/Numbers etc. dumped_text = "===>"+arr+"<===("+typeof(arr)+")"; } return dumped_text; } var myObj = <?php echo json_encode($checkin); ?>; alert(dump(myObj)); Sorry for the bloated code, I normally work in Java and PHP so although I understand the theory, I haven't worked with objects much in JavaScript before. Any help would be much appreciated! Hello everyone, I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object. In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element. anyObj has 3 properties and one function increaseWidth() increaseWidth() creates a new button with an onclick event handler and this is where I have a problem. The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj. The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me. So, what I am asking advice on is, is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function. Code: function anyObj(divObj){
this.elem = divObj;
this.width = 50;
this.height = 50;
this.increaseWidth=function(){
width = this.width;
height = this.height;
//create a button for this object to be appended to an element later on
var newButton = document.createElement('button');
newButton.onclick=function(){
width += 10;
//...
//...
}
//...
//...
}
}
I want to have button2 populate form fields in a separate form with certain data I choose. The challenge is that the name of each text box is the same ("inputbox") and the id is dynamic, the first part only staying the same. So, the form element id would be "idb_4555557805340560...". There would only be one form element that begins with "idb." The following code works, but doesn't address the dynamic id. How can I do this? Code: <HTML>
<BODY>
<SCRIPT LANGUAGE="JavaScript">
function writeText (form) {
document.getElementById('ida').value = "Have a nice day!";
document.getElementById('idb').value = "Have a nice day!!";
document.getElementById('idc').value = "Have a nice day!!!";
}
</SCRIPT>
<form name="one"><INPUT TYPE="button" NAME="button2" Value="Write" onClick="writeText(document.myform)"></form>
<FORM NAME="myform" ACTION="" METHOD="GET">
<INPUT TYPE="text" NAME="inputbox" id="ida" VALUE="">
<INPUT TYPE="text" NAME="inputbox" id="idb" VALUE="">
<INPUT TYPE="text" NAME="inputbox" id="idc" VALUE="">
</FORM>
</BODY>
</HTML>
Hello there! I am completely new to these forums and to programming in general (however, I used to program some games, albeit not very good ones, on a version of BASIC that came with my Playstation 2 about 10 years ago hehe). I have a basic understanding of functions, loops, if/else/switch and an extremely basic understanding of objects/methods. I wanted to consolidate my knowledge by putting it to practical use so I have made a little text adventure game. At the moment it is horrendously non-user-friendly as it has just been me experimenting with functions, if/else statements etc. Anyway, below is my code and I have two specific questions regarding it (but general answers telling me how I could do things more efficiently OR telling me what I should consider studying would be very appreciate also :)). Firstly, I have a little inventory object up top and when the player picks up something in the game I change the inv item to "true" so they can use it later (it seemed logical!). I would really love to know how the user could type in "inv" and for their inventory to be shown back to them. i.e. How could I show only the "true" items of an object? I have tried coding this myself but I really am stumped for an answer. Secondly, you can see in the "north21" function within the "north2" function that I used a series of if/else statements instead of a switch. I would have much prefered to use a switch and then for the case of "go north" have an if/else statement to check if vineclear is true or not (so that they can pass through to the non-existent north3 room). Is this possible? You can use if/else statements within an if/else statement but it seemed when I tried doing that in a switch it didn't like it. I am running this script through an interpreter to play the "game". I understand that JS probably isn't the best for what I am trying to do, it was more just a "see what I can do" exercise more than anything. Thanks in advance for your help and please be nice to me, forums scare me generally :D testgame.txt I have to attach the code in a txt file as for some reason it wasn't displaying properly when I copied and pasted it here.

My code is designed for display in an HTML page, not for use in clumsy console.log( ) coding. prompt() and alert() and confirm() and document.write() and console.log() should be used ONLY when debugging, not for any real work. But if you must use console.log, then try this, to replace the code in italics: Code: return "You have these items in your inventory: " + list.join(",");
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 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. 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 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 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?? Ignore post (if mod, please delete)
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. hy all, I am creating an accordion menu that when i press the " UNIT " tab, it opens up a list of " Chapters " tab, and when i press on any one of those chapters, a list of lessons opens up.

Please HELP! Hello, I have a simple form with simple validation. I am just playing around a bit with forms and don't really have concrete knowledge. What I have done is created a form. Asking for first name, last name, age and email. When the user clicks the submit button I want 2 functions to run, the first checking the input is correct and also making sure all fields have a value. Once everything is checked and is O.K I want to go into another function which sends all this information to an array one by one. I am having difficulty accessing each individual input tag. I could achieve what I want to do, but it will take double the lines of code because each input has a different 'name'. So, what I am trying to do is access the input tags the same as you would do an array. Here is my code: HTML: Code: <form name="regForm" id="form"> <fieldset> <legend>Real Heroes - Registration Form</legend> <p>First Name:<input type="text" size="30" maxlength="20" name="txtFirstName" /></p> <p>Last Name:<input type="text" size="30" maxlength="20" name="txtLastName" /></p> <p>Age:<input type="text" size="30" maxlength="3" name="txtAge" /></p> <p>Email Address:<input type="text" size="30" maxlength="50" name="email" /></p> <p><input type="button" value="Submit Registration" name="butChkForm" onclick="callFuncs_onclick()" /> <input type="reset" value="Reset" name="resetForm" /></p> </fieldset> </form> JavaScript: Code: //CALLING THE FORM SCRIPTS//
function callFuncs_onclick()
{
chkForm_onclick();
creatingDatabase_onclick();
}
//**************FORM VALIDATION***************//
function chkForm_onclick()
{
var theForm = document.regForm;
if (theForm.txtFirstName.value == "" || theForm.txtLastName.value == "" || theForm.txtAge.value == ""
|| theForm.email.value == "")
{
alert("Please complete all of the form.");
if (theForm.txtFirstName.value == "")
{
theForm.txtFirstName.focus();
}
if (theForm.txtLastName.value == "")
{
theForm.txtLastName.focus();
}
if (theForm.txtAge.value == "")
{
theForm.txtAge.focus();
}
if (theForm.email.value == "")
{
theForm.email.focus();
}
}
else if (isNaN(theForm.txtAge.value))
{
alert("That is not valid input for this field. Please re-enter your age.");
theForm.txtAge.focus();
}
else
{
alert("Thank you for completing the form, " + theForm.txtFirstName.value);
}
}
function creatingDatabase_onclick()
{
var form = document.regForm;
var index = form.input[0].value;
alert(index);
}
I'm not quite sure where I am going wrong. Please note that these functions really labour the point, I know I have way too many lines of code but I am still very amateur with JS. Thank you for any help/information. Kind Regards, LC. Hello, I am working on a project using HTML and javascript to allow the user to choose a vehicle from a drop down menu, then load a new page showing some information about this vehicle. The information is stored in an Excel file. I posted regarding this issue a while back and got an excellent response from Old Pedant (thanks again!) about using ActiveX - which has thus far worked perfectly. My initial condition was that I would only be using IE7+. However, my next idea was to be able to use it on an IPad (which I unfortunately do not own yet, making any kind of testing difficult) which I am fairly certain ActiveX won't work on. So, I was looking for any other method which would be similar. Important note: this will not use the internet at all, all of these files will be available locally. There is a lot of material on running queries to servers, but I didn't think that would really apply here. It seems pretty clear that JS has difficulty accessing files client side (which I understand why completely), but I was hoping to find something that worked for the gray zone I'm currently working in since I'm not using servers at all. I know that this is not really the intended use of HTML/JS, but I was hoping that by writing it as an HTML file, it'd be accessible to anyone with a browser. Some of my target computers have odd limitations (such as not being to download .exe files). The code I based my original off of is shown below: Code: <script type="text/javascript">
var conn = new ActiveXObject("ADODB.Connection")
conn.Open ( 'Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\full\path\to\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";)';
var sql = "SELECT * FROM [nameOfSheet$]";
var rs = conn.execute( sql )
while ( ! rs.eof )
{
// just an example of dumping everything from the sheet out to the browser:
for ( var f = 0; f < rs.fields.count; ++f )
{
document.write( rs.fields(f).value + "," );
}
document.write("<br>\n");
rs.moveNext();
}
rs.close();
conn.close();
</script><script type="text/javascript">

Is the line below correct for this task? Code: document.Purchase.(Tax+i).selectedIndex; i have this code: PHP Code: <?php foreach ($freechat_list as $r) { $uniqueCode = substr($r,0,12); $id = substr($r,13); $blocked_record = RcBlockListTablePeer::isBlocked($id,$requestor_id); ?> <a href="#" id="profilelink" name="profilelink" onClick="return viewornot(<?php echo $id."/".$blocked_record; ?>)"><?php echo $uniqueCode; ?></a> } then i have my JS: [CODE] thank you all but i am totally confused now...here is my full code: <?php foreach ($freechat_list as $r) { $uniqueCode = substr($r,0,12); $id = substr($r,13); $blocked_record = RcBlockListTablePeer::isBlocked($id,$requestor_id); ?> <a href="#" id="profilelink" name="profilelink" onClick="return viewornot(<?php echo $id."/".$blocked_record; ?>)"><?php echo $uniqueCode; ?></a> } my JS: Code: function viewornot(id)
{
alert(id);
}
alert(id) only gives me the id but in my href i concatenated it with blocked_record: viewornot(<?php echo $id."/".$blocked_record; ?>) please help? |
