I am creating a chat script that uses PHP and Javascript. For part of it I need to empty one of the text boxes. The scripts I use work fine in IE and Firefox, however the the text box will not clear in Opera and Konqueror. I have tried the follwoing:
document.getElementById('commentbox').innerHTML = ''
and
document.chatform.comment.value = "";
Like I said they are both fine in IE and Firefox, but not in Konqueror or Opera. I have searched for hours looking for code that will work.
I discover a strange bug in Konqueror 3.1.1. I design a javascript application which acts in one file called example.html. At the beggining of this js i write:
if (document.images) { folderopen= new Image(16,16); folderopen.src="http://www.sergioamo.8m.com/buttons/folder_open.png"; folderclose= new Image(16,16); folderclose.src="http://www.sergioamo.8m.com/buttons/folder_close.png"; } functions.... .... ... .. and my javascript works perfect. If i write:
if (document.images) { folderopen= new Image(16,16); folderopen.src="./buttons/folder_open.png"; folderclose= new Image(16,16); folderclose.src="./buttons/folder_close.png"; } functions... .... ... .. my javascript does not work properly. Does anyone knows if is imposible to use relative references with konqueror 3.1.1 or which is the problem?
Is there an equivalent in Konqueror's KJS engine to Gecko's __defineGetter__() and __defineSetter__() methods? Our web application uses a ton of Javascript, written based on Internet Explorer's object model as that's the primary platform that we're supporting. For Netscape support we uses __defineGetter__() and __defineSetter__() to emulate the many IE-only properties. I've tested our site using Safari, and to my surprise, it renders perfectly. Alas, it's completely non-functional. If it's somehow possible, I'd love to write a similar emulation library for KJS so that our non-Windows users would have an alternative to crummy Netscape/Mozilla.
I am trying to capture the image coordinates when a user clicks on an image. My code is working in Firefox, Mozilla, Netscape, IE, and Opera, but fails under Konqueror (and I suspect Safari). The code below fails in Konqueror when the page is scrolled down; the coordinates are off by the scroll amount.
My code in the html img tag: onClick="MLDot(event)"
The left frame has a DHTML-generated tree of links (to images). The right frame displays the image link you click in the tree of links.
It works great on all browsers except Konqueror/Safari, where it displays the first image link you click on in the tree of links. But then subsequent clicks on other links do nothing.
That is, the first time you click on a DHTML-generated link, Konqueror/Safari loads the corresponding image in the other frame. However, after that, when you click on links, the other frame is not updated.
<script language="JavaScript1.2" style="text/javascript"> <!-- function checkLocation() { if (navigator.userAgent.indexOf("Opera")!=-1) type="OP" else if (document.all) type="IE" // ie 4 & up else type="XX" if (type=="IE") moveNav.style.pixelTop=document.documentElement.sc rollTop setTimeout("checkLocation()",5); } //--> </script>
This is suppose to keep the Nav bar at the top of an IE browser. (Yes, it wobbles a little bit, but what can I do?)
With most other browsers, the Nav Bar stays nice and stationary at the top, thanks to a nice CSS solution. However, with Opera (at least Opera 7.54 that I have) the nav bar wobbles a bit like I would expect it to in IE, but still it gets hidden under most scrolling situations. What's the cure for Opera?
I have strange situation, in my webb apps i use a lot of AJAX. in my developer computer i use opera and naked apllication (it's using Python Application Server cherrypy www.cherrypy.org), in production I covered my application be Apache server which serves static files. The problem is that AJAX working in Opera but only on production server (cherrypy behind Apache), on developer machine it's not working. Others browser (IE, FF 1.5.0.1) working without any problem. Does anyone know solution for this? Or is is a way to lookup what is happen under Opera engine? any plugin or something what shows AJAX status call?
I really want to make my scripts work in Opera. I really, really do. But it seems like an uphill struggle. First of all, I can't get ANY kind of debug output. No error messages in the "javascript console" - but then, I have never seen ANYTHING in Opera's javascript console. Is there some kind of voodoo I need to perform in order to make that work?
Then, when Opera doesn't like something about a script (even if it works fine in Spidermonkey), it will sometimes refuse to load it entirely, which means I can't even do alert() based debugging. What the hell?
Can anyone give me some insight as to how they go about making their scripts run properly in Opera? I make a point of sticking to ECMAScript standards (and then making per-browser exceptions where needed *COUGH IE*), but Opera just doesn't want to cooperate.
This is in Opera 8, by the way. I haven't upgraded yet, since I don't use it, and I think more people still use 8 than 9 so that's what I want to target.
Has any user of Opera 7.11 noticed that it does not reload all files when the reload button is clicked? I can click on my html file to cause Opera to load and start and it's OK. But if I then correct an error in a *.js file and click reload I often get a javascript console with the same error that I just corrected and line numbers that refer to the old file. This has got to be something that I am doing wrong, but I can't see it.
I have included a file below that tests onKeyPress in Opera 7.11. I am getting peculiar behavior. When the file is first loaded, pressing the keypad + causes the textarea to get physically larger on the screen, and pressing the keypad - causes the textarea to get physically smaller. I click on the scrollbar then this behaviour stops and subsequent keystrokes are displayed appropriately. Is this some kind of bug in Opera 7.11? Code:
I'm in the process of migrating a script to use DOM core methods but I've hit a roadblock in the aforementioned browser. The following code snippet illustrates what I'm basically trying to do, it really is incredibly basic!
var newimg = document.createElement('img'); newimg.setAttribute('id', 'placeholder'); newimg.setAttribute('src', 'images/large/courtyard.jpg');
I'm then positioning the element on the page using appendChild(). Everything works perfectly on Firefox 1, IE5+, Opera 8, Konqueror 3.3.1 (Linux) but not in Opera 7.54. I suspect the element is being created as associated styling on #placeholder is being applied (just some padding and borders) but the image itself is not being displayed. I assume therefore that the problems lies with setAttribute()?
This seems like the sort of problem that others would have encountered, but I haven't been able to find mention of it anywhere.
document.getElementById("p").setAttribute("disabled","true"); to disable a button after user clicks it (this is to make sure user clicks it only once). It is needed to prevent multiple clicks on a button since each click calls a servlet.
This code works in IE but does not in FF and Opera.
google.maps.event.addListener(markerName, 'click', function mojafunkcia() { document.getElementById("neco").getElementsByTagName("a")[0].click(); })
I assume that html element cannot access that javascript function because it ist nested within other function (please see source code on turie.eu), but I'm not very skilled with javascript, so I'm not sure.
the code above gets called every time a new page is loaded inside the iframe (ifrmDisplay) what its doing is resizing the iframe so it can have the same size as the page inside it, so i can eliminate the need for vertical scroller for the iframe, i assumed that it works on opera and IE at the same time, when i tried it out, it worked on IE but not on opera. after lot of time in researching how i can get workaround this issue with opera, that is the best possible solution i have and yet it doesnt work. so i gave up and asking you if you can help me out here , coz this is jst driving me crazy!
the problem is im not a javascript expert, to be honest i jst started doing javascripts about two days ago, that is why im in need for help
by the way, here is inner html for the iframe if its any use
I've noticed that screen.availHeight/availWidth don't return correct results in Opera 8, meaning that what Opera returns are the pure screen dimensions, no the actual dimensions due to taskbars or similar. On the other hand other browsers (MSIE, Netscape, Mozilla) get this correct.
In Opera 8.01 (Linux; Build 1204) and in Opera 7.54 (Windows XP; Build 3865), my form disappears from the HTML markup (below). To summarize:
1) In a <script> block in the <head> I create a form element (part of object/feature/bug detection). 2) There's a <form> element defined in the <body>, with the id 'theForm'. 3) The onload function tries to access that form, and also counts the total number of forms in the document. It fails to get a reference to the form; the count is 0. Code:
After my web page has been loaded I'm doing some tests with a JavaScript. If I figure out that something is wrong I'd like to reload the whole frameset.
With Internet Explorer and Mozilla Firefox I can reload the whole frameset with parent.location.href = "index.html";
However, this doesn't work with Opera. Does someone know how to do that with Opera?
The « navigator » object contains strings which specify the browser and version; however, this is in general not very genuine. Mozilla (and therefore Netscape 6+) allows this to be freely set, and Opera and IE allow it to be modified. There are also at least 25 other javascript capable browsers with their own strings here.
Generally though, you don't need to identify which browser is being used. There are alternative techniques, but which one you choose depends on why you want to redirect browsers. If it's to offer different CSS stylesheets, then....
Opera 7 doesn't appear to support the <script> element in XHTML. Does this mean that it impossible to use Javascript with XHTML? Or is there a workaround, such as the legacy method, in HTML, of commenting out the Javascript code.
I've been trying to make this simple script compatible across various browsers. It works for IE 6.0 and NS 7 but doesnt work with Opera (I have version 7.11). This is what is supposed to happen: when the user clicks a button in the main window, a dialog window pops up. In the dialog the user enters a university to search for. When the string is submitted, the dialog then shows all the matches found in the database. The user picks one and clicks the Submit button. The Submit button's code is as follows:
