JavaScript - Need A Quick Refresher- Why Doesn't This Work?
I'm having one of those moments right now. Can someone explain why the following alerts "undefined" instead of "George"?
Code: function test(){
this.worker='George'
}
test.sayname=function(){
alert(this.worker)
}
test.sayname() //alerts "undefined"
I know I can get it to alert "George" by instantiating test(), but I thought the above should work even without doing that. Similar TutorialsI have a website at: http://www.zionism101.org/defaultfornow.aspx The page works on Google Chrome, Mozilla Firefox, and IE-9. It sort-of works on IE-8, however, the problem is that on IE-8, there is about 2 seconds where everything is shown on top of everything else in a mess. This is bad. The website is unusual in that it uses a menu to slide screens from right to left. This has implications. For instance, I need the menu to appear on all screens, so I use absolute positioning, and then use javascript to calculate the center position. The same goes for a logo image. And on top of that, some screens (which are really DIVs) have items positioned by absolute and relative positioning within them, and those positions are often calculated via javascript (and then set). On IE-8, the result is not good. I think what is happening is that the browser first shows everything as it appears before javascript is run, and then slowly the javascript is run, which puts everything in the correct position. So initially, not only is everything in the wrong position, but different DIVs appear on top of each other. I could tell every user to get IE-9 or chrome, but thats not a good solution. Thanks, Gid P.S. one solution might be to make the screen go black for an instant, until everything has settled down. If thats the only solution, how would I do that? P.P.S. there are actually 3 pages in the site: the login page, the logout page, and the founders page. Everytime the user switches between them, the jumble for 2 seconds occurs. I need a Javascript refresh script that can refresh a page after a certain amount of milliseconds, but I want the script to stop refreshing when there is a certain tag or id on the page such as <div id="blue"> or something like that. How can I go about doing this? I have a few tabs on my website. They're each set to the corresponding id in the JS file. It's supposed to add #tab-1 to the end of the URL in the users browser when it's clicked. For example, when a user is at mypage.com and they click on the tab, it ads mypage.com/#tab-1 to the end. How come it doesn't do what I want when I click it though? Here's an example of how it's setup. HTML: <a href="#tab-1" id="tab1">Text</a> JavaScript: document.getElementById("tab1").onclick = function(){ this.href += "#tab-1"; } This is a script which has a window slide down on the page and a user can choose yes/no to continue. It works in all browsers other than IE...any help please? If you need more info, please let me know. Thanks. <script language="JavaScript" type="text/javascript"> <!-- var allowpop=1; function popWin(){ var ppl="popLayer";var objppl=findObj(ppl); if (objppl==null){return;}// if the layer does not exist, do nothing. var args=arguments,movetoX=parseInt(args[0]),movetoY=parseInt(args[1]),movespeed=parseInt(args[2]); var cycle=10,pxl=""; if(!document.layers){objppl=objppl.style;} if(objppl.tmofn!=null){clearTimeout(objppl.tmofn);} var pplcoordX=parseInt(objppl.left),pplcoordY=parseInt(objppl.top); var xX=movetoX,yY=movetoY;if((pplcoordX!=movetoX)||(pplcoordY!=movetoY)){ var moveX=((movetoX-pplcoordX)/movespeed),moveY=((movetoY-pplcoordY)/movespeed); moveX=(moveX>0)?Math.ceil(moveX):Math.floor(moveX);movetoX=pplcoordX+moveX; moveY=(moveY>0)?Math.ceil(moveY):Math.floor(moveY);movetoY=pplcoordY+moveY; if((parseInt(navigator.appVersion)>4||navigator.userAgent.indexOf("MSIE")>-1) && (!window.opera)) {pxl="px";} if (moveX!=0){eval("objppl.left='" + movetoX + pxl + "'");} if (moveY != 0) {eval("objppl.top = '" + movetoY + pxl + "'");} var sFunction = "popWin(" + xX + "," + yY + "," + movespeed+ ")"; objppl.tmofn = setTimeout(sFunction,cycle); } } function findObj(theObj, theDoc){ var p, i, foundObj; if(!theDoc) theDoc = document; if((p = theObj.indexOf("?")) > 0 && parent.frames.length) {theDoc = parent.frames[theObj.substring(p+1)].document; theObj = theObj.substring(0,p);} if(!(foundObj = theDoc[theObj]) && theDoc.all) foundObj = theDoc.all[theObj]; for (i=0; !foundObj && i < theDoc.forms.length; i++) foundObj = theDoc.forms[i][theObj]; for(i=0; !foundObj && theDoc.layers && i < theDoc.layers.length; i++) foundObj = findObj(theObj,theDoc.layers[i].document); if(!foundObj && document.getElementById) foundObj = document.getElementById(theObj); return foundObj; } function hideLayer(layername){ layer=findObj(layername); if(layer.style){layer=layer.style;} layer.visibility='hidden'; } // --> </script> Hi!

Thanks! Dr. T. I've got a form textarea on my site, which after being submitted is stripped by my php file. Then my javascript kicks in and does some analysis of the entered text. However everytime the user entered a hard return within the textarea my javascript gives me an error 'tekenreeks niet afgesloten' which means something like 'string is not closed'. Therefore I decided to replace all occurences of chr(10) and chr(13) with ok2 (just some random characters), I did this with php which worked fine, and I didn't get the javascript error. However I need to reshow the entered text (original) to the user, so I need to restore the old values. I tried Code: result.waarde.replace('ok2', 'chr(13)');
but it doesn't work, as it still displays ok2. I'm no expert in javascript, but how can I replace those characters by the hard returns? Oh yeah I'll show some more coding, perhaps the error can be found the Code: result.waarde.replace('mdw', 'chr(13)');container.innerHTML = result.waarde;
and in my html: Code: <div id='waarde' style="width:500px;"></div> Heya, I wrote the following page in a day or two (please don't mind the layout). Everything seems to work excellent, apart from in Firefox (FF) in which it doesn't seem to work at all. None of the other browsers have any trouble with it. I'm pretty new to Javascript (everything you see in the source code is pretty much all I know) and I have absolutely no idea why it doesn't work in Firefox. The page in question could be found [link has been removed]. It's all there is to it. So yeah, how to actually make this work in FF? Thanks a whole bunch in advance!

It should make the first blue, second red, and third yellow yes? Hi! I'm new to JavaScript and I've done some small adjustments to my clients site, but it won't show properly in IE (the shadowbox js at least.). I thought js was accepted in all newer browsers. Do you have a quick fix or idea on why it doesn't work? You can view source on my site, I use mootools, and shadowbox/corners and rightclick blocker. Is it generally a 'bad thing' to use js in webpages I want everyone to view in the same way? I tried the same effects with CSS but it's not supported in the same way corss-browser, unfortunately. The 'no selection' CSS class I have on the site is also not accepted in IE. It's very annoying! http://santinacrolla.ihaarr.com/p thank you in advance! Below is code using the onmouseover event, but it doesn't work. The only thing that appears in the status bar is the URL. What am I doing wrong? Code: <a href="http://codingforums.com" onmouseover="window.status='This is an OnMouseOver event'; return true" onmouseout="window.status=' '; return true">Put your mouse here to see status info change at bottom.</a> Code: var f = [];
for ( var f1 = 1; f1 <= n; ++f1 )
{
var f2 = n / f1;
if ( f2 == Math.floor(f2) )
{
f.push(f1);
f.push(f2);
}
if ( f2 <= f1 ) break;
}
f.sort();
Someone helped me make this factoring code, but if n = 6, it returns [1,2,2,3,3,6,6,6] Any ideas? I am looking for [1,2,3,6] I have the following script in the head; Code: <script type="text/javascript">

Hello, I'm new to javascript and html5. I've been having problems with some simple(?) lines of code. Code: var ctex;
var totalX = 400;
var totalY = 300;
var racpad = new Image();
racpad.src = 'Imgs/paddle.gif';
var brixadow = new Image();
brixadow.src = 'Imgs/brickLight.gif';
function initCnv()
{
canvas = document.getElementById('canvas01');
ctex = canvas.getContext('2d');
AppStep();
}
function clearcv(x)
{
ctex.clearRect(0, 0, totalX, totalY);
ctex.fillStyle = x;
ctex.beginPath();
ctex.rect(0, 0, totalX, totalY);
ctex.closePath();
ctex.fill();
}
function AppStep()
{
clearcv('black');
ctex.drawImage(racpad, totalX/2, totalY-50);
}
What I'm trying to do is to simply turn the canvas black and show a small gif on it. Upon executing initCnv(), the canvas turns black as it should, while the sprite image doesn't show up at all. I can't figure out what's going on, I scoured the code for syntax errors, even tried other image formats but to no avail. Image paths are also correct. Maybe the problem's an extremely noobish one, but I still couldn't get a clue, so I thought I'd ask for help around here.

The <b>scrollHeight</b> dimension may be useful for a variety of reasons; for example, the height of the <b>div</b> could be set to the <b>scrollHeight</b> to conserve horizontal space while respecting the set width as a maximum. </div> <p><button id="btnCheck" onclick="fnCheckScroll()">Check scrollHeight </button></p> <p><button id="btnSetIt" onclick="return(fnSetHeight());">Set DIV height to scrollHeight </button></p> <!-- START_PAGE_FOOTER --><br> <br> <br> </div> </form> </body> </html> dears, am trying to redirect user from onchange event to another location in the page. its work fine in IE but not in firefox :-( why window.location doesn't work in FF ? Html: Code: <form name="forder"> <select name="bycat" onchange="gocat()"> <option value=1>one</option> <option value=2>two</option> <option value=3>three</option> </select> </form> javascript: Code: function gocat()
{
window.location ="index.php?show&cat=" + forder.bycat.options(forder.bycat.selectedIndex).value;
}
any idea???? I have a page with a Geo IP redirect that's supposed to redirect users from London to URL#1 and the rest to URL#2. It's an external geo ip lookup service. First comes the IP lookup: Code: <script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"> /* GeoIP Deny Access by City and Redirect Javascript 1.0 http://wiki.category5.tv/MaxMind_GeoIP_API API (c) MaxMind - www.maxmind.com - used with permission "GeoIP Deny Access by City" script by Robbie Ferguson, www.Category5.TV You are free to use and share this script, however this notice must remain intact. */ </script> And then, and here's the problem I think, is the redirects inside an if/else: Code: <script type="text/javascript">
var city=new Array("London, H9")
var redirect="http://www.URL1.com"
var redirect2="http://www.URL2.com"
/* do not edit past this line */
Array.prototype.inArray = function(q) {
for(i in this) { if(this[i].toUpperCase() === q) return true; }
}
var myCity=geoip_city().toUpperCase()
var myRegion=geoip_region().toUpperCase()
if(city.inArray(myCity+", "+myRegion))
{
window.location = redirect;
}
else
{
window.location = redirect2;
}
The redirect works if you are indeed from London. So if the if-statement is true, "window.location = redirect" works, but if the statement is not true, "window.location = redirect2" doesn't seem to be called. Help would be extremely appreciated Hello, I'm trying to combine two different jQuery scripts on my webpage. The one is showing flashvideos in a lightbox and the other one is displaying thumbnails in a slideshow. The problem is that only one script is working. I have searched the web and forums and found that several people have had this problem before and I have truly tried to fix it with noConflict(). The problem is that I have very little experience in Javascript so I haven't got it working. So, here are the lines in the code: <!-- Video lightbox --> <script type="text/javascript" src="/js/videolightbox/mootools.js"></script> <script type="text/javascript" src="/js/videolightbox/swfobject.js"></script> <script type="text/javascript" src="/js/videolightbox/videobox.js"></script> <!-- Thumbnail slider --> <script type="text/javascript" src="/js/jquery-1.2.6.js"></script> <script type="text/javascript" src="/js/carousel.js"></script> I haven't coded any of these myself (of course), so I am not familiar with the variables in the files. So my target is to find a way to to use these scripts simultaneously. I am very thankful for your help but I am also kindly asking for a simple and easy to understand instruction. The webpage can be found he http://wearethemusicmakers.se/index2.php Best Regards Johannes I'm trying to resolve a UPS zone from a zip code, here is my code: Code: <script type="text/javascript">

Can someone see my error? I'm a bit rusty at my javascript. |
