Navigator.javaEnabled Always Returns False In Mozilla/Opera
Jul 23, 2005
I am trying to test changes to my site (made only on my local machine so
far) in IE v6, Mozilla 1.6, and Opera 7.5.
When I test "navigator.javaEnabled in IE it corretly reports true/false
depending on whether javascript is enabled.
However, both Mozilla and Opera *always* return false. How can I properly
test to see if javascript is enabled/disabled in these two browsers? (If you
have a reference on the web, please point me to it as I've spent several
hours trying to find what I need.) Code:
Either I'm having a really dim Friday, or something strange is going on. I'm trying to add a method to the Validator plugin, using the following regex:
When I create a new div and insert it with .append(ndiv) to an existing div ndiv.width() returns the width of the parent div instead of the actual value. This is the same in FF4 and IE9 so I suppose this is a regular behavior and I just don't realize how to deal with it.
I am currently using the simplemodal confirm dialog from Eric Martin. What do I need to modify to have the confirm dialog return true if the user clicks Yes, and false otherwise. for example something like this:
I have a simple form here with a function to validate it, but I have no idea where I'm going wrong. I'm very familiar with ActionScript and C++, so I get the coding aspect of it, but one thing I'm not familiar with is how exactly JavaScript and HTML communicate. The problem is that this form always submits, even if my function returns false...but I can't even see if it returns false anyway, because alert() doesn't seem to be working either.
We've got a server-side page (status.php) that dynamically generates a GIF image. The displayed image depends on the value of a boolean field in a database. Just calling the page displays the current value of the boolean, calling it with a parameter switch (status.php?switch) flips the database value and generates a new image. We've included headers to prevent caching of the image by the browser.
Whenever our HTML page is displayed in the browser, we just include an image that shows the current status: img src='status.php'/
We want to allow the user to click the image, which then inverts the boolean status in the database: img src='status.php' onclick='this.src=status.php?switch;'/
This works great in Internet Explorer, but both Mozilla and Opera only allow to switch once. My idea of the problem is that those browsers think like this; after one click, the src is already 'status.php?switch', so changing the src again would be redundent in their eyes, so they won't do it.
We found a temporary solution by generating the current time as a parameter in the image URL: img src='status.php' onclick='this.src=status.php?switch+(new Date());'/ However, this is not a very elegant solution.
Does anyone know a proper solution to this? This means, forcing Mozilla and Opera to load an image using JavaScript, even though the URL of the image didn't change?
Have an issue with using $.ajax for requests. If I set async: false it works fine, but sometimes gets cached content. If I add in cache: false then async doesn't work anymore, the next ajax request gets called before the first one finishes.
navigator.userAgent returns information about the user operting system, Browser etc.
Usually you get somthing like:
Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) or Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) or Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax)
imho there is too many information, most of it confusing for the user. What I would like to do is, evaluate the information and reduce it to the opereting system and browser version.
e.g.
MSIE 6.0, Windows XP
or
Netscape 7.1, Windows 98
obstacles: - As far as I know, the structure of the data returned by navigator.userAgent depends on the browser. So a specification for each browser would be a good starting point, any ideas where to find?
- Why do I get "Windows NT 5.1" instead of "Windows XP"? Any other synonyms?
I need to know that navigator (IE or FF) was restarted or just know that cache was deleted.When I change sth in JS script, my old script is still in user navigator cache. I need user to use my new script, so he/she must clear cache or restart navigator (or maybe sth else). I show allert() that he/she mast do it, but how can I ckeck he/she did it?
had this in browsers areas but people told me I should put it here in Javascript because more people here would probably have seen it before and know why it happens. I have basic Javascript that rotates images. I've noticed any kind of Javascript code that rotates images has this same problem only in Mozilla. When the images rotate in Mozilla in between the rotations, Mozilla browser adds a little colored square that represents a blank image that are able to be seen does anyone know why Mozilla Browser adds that? For example when looking at this page in Mozilla can see it. if you know if this is some Mozilla problem with Javascript and images. Doesn't happen with IE and other browsers shows the images only and nothing else.
I am trying to read all the navigator object elements
1. Using the navigator.length returns undefined, cant use for loop;
2.Using and array of known elements like var a = Array("appCodeName","appName","appVersion"); I seem to miss something to get it combined like navigator.a[i]
I dedicated some time creating my own carousel with images, and got a little problem:
It works perfectly when I´m on the website, but when I change between the tabs on firefox/chrome, it seems that the function make some kind of queue, and when I come back to the website, it execute the function a lot of times at the same times, passing between the images in less than half second (I configured to change every 5 seconds).
function circCar (car) {
Here is the code, and if anybody wants to see the problem, open this url, open another tab (blank or another website) and stay on it about 15 seconds, when you come back to my site, you will see the queued function. [url]
I've a BIG Problem With a HUGE JS application , i'm modifying its javaScript code to work on both IE/Mozilla , currently it works fine on IE but not on Mozilla.
My main Point now is events.
Lets try with a little module, consider this function :
And it is attached in this place like :
This works fine in IE , i want to modify it to work on Mozilla.
I'm picking apart the Yahoo! UI event.js library and stripping it down to just what I need. I'm also trying to make the parts I use better. I'm stumped on how to fix the code for the getPageX() method. This method is supposed to give the same value in IE as other browsers for the event position relative to the left of the page. This value will be greater than the position relative to the left of the browser if the browser is scrolled to the right. What would be the appropriate feature detection to use for the conditional in the following line?
I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.
Do you have to use the onClick attrib to have return false work?
i.e. is it possible to do <a href="javascript:somefunct();return false;"> and have the page not reload with 'false' or the browser not complain about illegal use?
I have a page built with asp.net that includes some "imagebutton"s within a form. These render as input tags with the type set to image. I ahve the onclick attribute set to run a custom javascript function and return false.This has worked fine for the few months the code has been in place and then just recently (within the last few days) it has stopped working for a single network user. They click on the link and instead of the function executing (and the AJAX loading details into the page) the form submits. This makes me think that the "return false" simply isn't executing. The user says that they haven't changed any settings or anything that may cause this issue...
The browser being used throughout the company is IE8 under Windows XP. I have checked the version being used on their comptuer and it is 8.0.6001.18702, which is the same version as the one installed on my local machine which is working fine. Another user has logged into the computer being used by the user with the issues and it works fine for the second user.
This has stumped me for the last couple of hours and I was wondering if anyone else could shed some light... I have a page which loads some cookies, when taking the value from the cookie it defines whether a checkbox should be ticked or not. This works if the value of the cookie is true but not if the value is false and it ticks the box anyway. The code is....
var widgetVal = loadCookie(widgetName); switch(i){ case 1: document.getElementById('calender_widget').checked = widgetVal; break; [Code]...
i is incremented each time in a for loop and a different cookie is loaded each time. As I said the code works if it set to true but not false however if I remove the variable and specify it as false it works.
i am learning JS at school and it is going pretty well. One concept I seem to be having trouble with is Return False; I understand that it is used when working with boolean types, but I seem to see it in other places as well, apparently to stop a function from doing something. I was wondering if someone had a good reference that explains the difference uses of return false.
I have look through the forum and couldn't find the answer I was looking for, I am working my way through the simply javascript book and wanted to validate a form, if the form doesn't validate then keep the user on the same page and guide it with info, if it is OK then allow it to go onto another page, the javascrpt is on an external page and is called correctly, I have removed all the link info just so that it passes the spam filter. The return false does not seem to work, it will give me the alert box and then still move onto the jowebpage.
