JavaScript - Window Object
In my current javascript code, the window object is being used. But my issue is that if you are slightly zoomed in or out it is not placed correctly. So is there any way to make it take into account the browser zoom level?
Code: windowHeight=$(window).height(),windowWidth=$(window).width(), Code: projectedTop=scrollPos['scrollTop']+((windowHeight/2)-(correctSizes['containerHeight']/2)) Similar TutorialsHello 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?? I have a simple problem, I can't get the status bar to change. I am very new to javascript, and I am trying to practice some simple commands, and the onMouseOver event is suppose to change the status bar in my window. I can get it to change for onMouseOut but not onMouseOver. Here is what I have so far <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE>Exam</TITLE> </HEAD> <BODY> <H3>My Page</H3> <a href="http://www.google.com" onMouseOver="window.status='Visit google.';return true;" onMouseOut="window.status='Come back soon ';return true;">Visit Google</a> </BODY> </HTML> I have some code that creates a DHML window, I'll call that code MyDHTMLWin . Now what happens is I create a new MyDHTMLWin object and what happens inside that is it creates an iFrame. Now in my init method I do this.. this.iFrameObj.dhtmlWinObj = this; What I what to do is from inside the file loaded in the iFrame is be able to get the object that opened the window. I did used to do var newWin = new dhtmlWinObj(....); and then parent.newWin.anything() but this is no longer fit for purpose as I reuse this code and the variable names will change. But no matter what I try I just can't seem to get that object that should be stored in the iFrames dhtmlWinObj attribute. I thought it would be this.dhtmlWinObj but that doesn't work How can I get the object that opened my DHTML window??? TIA, Dale IE is throwing an error stating window.document.forms[...].elements is null or not an object. in the following code Code: var changeHandler = function() { this.form.calculateDependencies(); return true; }; for(var i = 0; i < arguments.length; ++i) { for(var j = 0, e = window.document.forms[arguments[i]].elements; j < e.length; ++j) { addEvents([e[j]], ["change", "keyup", "focus", "click", "keydown"], changeHandler); e[j].hide = hideEl; e[j].show = showEl; } (e = window.document.forms[arguments[i]]).calculateDependencies = calcDeps; e.calculateDependencies(); } } FF and Chrome seem to work ok, but it breaks in IE. What am I doing wrong here? 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 (); Ignore post (if mod, please delete)
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. 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 have this code i need to close the parent.html window when the child window opened, i need the code for that working well in IE and Firefox Parent.html <HTML> <SCRIPT TYPE="text/javascript"> function sendTo() { window.open('child.html','_blank','resizable=yes,width='+(screen.width-500)+',height='+(screen.height-500)+''); } </SCRIPT> <BODY > <form name="form"> <input type="text" value="" name="text1" id="pdetails1"> <input type="text" value="" name="text1" id="pdetails2"> </br> <input type="submit" value="submit" onClick="sendTo()"> </BODY> </HTML> child.html <html> <body> <form> <input type=text name="text5" value=""> <input type=submit name="submit"value="submit"> </form> </body> </html> Hello all, and thank you for your coments, I want to preserve a 16/9 aspect ratio to the window after any resize, making the width a function of the height. As I have a window.resizeTo() inside the window.onresize event function, the infinite loop is served. How may I quit it? Code: <html><head><title>Title</title><script languaje="javascript"> const c_ra=16/9; window.onresize = function WindowReSize() { var myWidth = 0, myHeight = 0; if( typeof( window.innerWidth ) == 'number' ) { //Non-IE // myWidth = window.innerWidth; myHeight = window.innerHeight; } else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) { //IE 6+ in 'standards compliant mode' // myWidth = document.documentElement.clientWidth; myHeight = document.documentElement.clientHeight; } myWidth = Math.floor(myHeight*c_ra); window.resizeTo(myWidth,myHeight); // ** CAUTION resize event in a onresize event handler ! }; </script></head><body><p>Hello World</p></body></html> Here is the program: http://www.1728.com/newwindow.htm Basically, I want to input a number in the input box, which assigns a number to the variable numval located at document.box1.b1. When clicking on the "new window" button, an alert displays the input box value, then another window opens and displays the integers 1 through 12 and the amount squared. I would like the new window to obtain the number from the previous window so that the new window will display integers (and their squares) from 1 to the value of numval. hello everybody i need your help and experience for having code to show ( overlay / modal window ) to the user when closing or navigating away from the page ( i want put in this window facebook share to make the user to share the page in his facebook ) , bytheway i wanna use it in my wordpress in every post could it be happen ? Thanks for helping I have created and opened a child window called "checkwin" and have written some data to it. If the data is valid, I want the user to click on the 'CONFIRM' button on the child window, at which time I want the "submit()" function for the form on the parent window to be executed. If the data is invalid the user clicks on 'MODIFY' and I want focus to return to a field on the parent form. However, when I click on the "CONFIRM" or "MODIFY" buttons on the child window, nothing happens. Here is the code: Code: checkwin.document.write("</td></tr><tr><td align='right'><input type='button' value='CONFIRM' onclick='opener.document.personnel_form.submit()'></td><td></td><td><input type='button' value='MODIFY' onclick='opener.document.personnel_form.first_name.focus()'></td></tr></table>") I have the code below in my popup window which currently brings up a blank page in the background as the main window. Instead I want the popup to come up but the original page I left is in the background as the main window. Does anyone know how I can do that with the code I currently have. Code: <html> <head> <title>JavaScript Popup Example 3</title> </head> <script type="text/javascript"> function poponload() { testwindow = window.open("", "mywindow", "location=0,status=0,scrollbars=0,width=350,height=400"); testwindow.moveTo(0, 0); testwindow.document.write('<h1>Get outta here!</h1><a href="javascript:void(0);" onclick="window.opener.history.go(-1); self.close();">Parent back button</a>'); testwindow.focus(); } </script> <body onload="javascript: poponload()"> </body> </html> Hi Ive found out how to force another browser window to open at a certain size when a link is clicked. Here's the whole line of code including the layer, the javascript and the image, <div id="Layer6" style="position:absolute; width:10px; height:8px; z-index:6; left: 561px; top: 310px"><a href="javascript:;" onClick="MM_openBrWindow('navigation%20instructions.htm','','width=50,height=50')"><img src="images/info.gif" width="15" height="15" border="0"></a></div> How do I adapt this so I can also specify the x&y co-ordinates of the opened window relative to the window that launched it. thanks alot Masten Hi All, I need to show/focus the parent window which is in back when click a link from child window in Chrome.This problem is in Chrome browser only.

You must pay attention to upper/lower case spelling, carefully. By the way, you shouldn't need the blur() call. If you focus on some window (any window) then any other focus should be lost. |
