How To Determine If Javascript Is Enabled?

Apr 4, 2003

I tried searching in the forums for this, but the search function keeps saying I can't search on less then 3 keywords? (I used the string in the subject!) Anyway... is this possible? I want to determine if JS is enabled, and display a "you must enable javascript to continue" if not.

Statistics On How Many People Have Javascript Enabled?

Mar 15, 2003

I wondered if anyone knew of any statistics about how many people have Javascript enabled/disabled. Also, what sort of policies do IT departments have towards it. I know of at least two large organisations that have Flash disabled for instance.

Using Javascript To Determine The Correct URL

Nov 16, 2005

I want to create a link to an email conference which is on 2 servers. Some users will only be registered on server1 and others will be registered on server2. however I don't know which users are on which server.

Is it possible to create some kind of JavaScript function which attempts to open a link to server1 and then if this fails default to server2. It would be far more user friendly.

Determine If Applet Is Loaded With Javascript

May 31, 2005

I call methods in a Java applet with javascript code like this:

document.myApplet.methodName();
This works great when the applet has loaded (the JVM has started and dowloaded all the jars) but it fails if the applet hasn't loaded yet, at which point it gives an error:
Quote:

Error: Object doesn't support this property or method

Is there a way to determine that the applet is loaded or not so that I can use it in an if statement? For instance, like so:
Code:
if (isAppletLoaded()) {
document.myApplet.methodName();
}
I tried
Code:
document.myApplet == null
but that didn't work.

Using Javascript To Determine If File Exists On Host Site

Jul 20, 2005

I'm new to javascript and PHP and I am wondering if there is a method or function to capture a 404 error in the event a particular html file cannot be found. I want to redirect that error to another page or design the code to send me an email telling me what page was selected and not found. In other languages I can trap such an error and respond to it.

Detect If An Add-on Is Enabled (firefox)

Jan 20, 2010

The code I am working on uses the idea of detecting mime type support, to see if the add-on is there. Then if the mime type is not supported, it assumes, the add-on is not installed. (No other add-ons have this mime type.)However, there is a problem, if someone disables the add-on, the there is no mime type handler in navigator.mimeTypes['the/MimeType'].Is there some way to detect if an add-on is installed, and also if the add-on is enabled?

Checking If Cookies Enabled

Oct 18, 2006

I have seen quite a bit posted about this, but nothing related to the different levels of privacy in Microsoft Explorer 6.0 under the internet options. I am using the script below to determine if cookies are on, but it looks like it only works if the settings are "Accept all cookies" or "Low". The default is "Medium" and the script fails at that setting or above. Do I have to require that the setting be higher than medium to use this code?

document.cookie = "TemporaryTestCookie=yes;";
if(document.cookie.indexOf("TemporaryTestCookie=") == -1) {
alert("Cookies are required to use this web site!
Please click the link at the bottom of the page
and review how to enable cookies! ");
}
else {; }

JQuery :: Tablesorter Is Not Enabled On Page?

May 27, 2009

I am trying out the Tablesorter in Wordpress 2.7.1 to make a membership list sortable. For some reason the sortable features isn't being enabled (or at least visible). Here are the steps I've taken so far: 1) In the header.php file I added the following code between the head
tags:

<head>
<script type="text/javascript" src="library/scripts/jquery-
latest.js"></script>
<script type="text/javascript" src="library/scripts/
jquery.tablesorter.js"></script>

[Code].....

But, while the table shows up on the page, the sortable features are not visible. NOTE: In Wordpress I have the WP-Table Reloaded plugin activated, but to trouble shoot this issue, I am not using the shortcode and using a HTML table directly in the page, for now.

Page Displaying Based On If JS Enabled

Jul 24, 2010

What I want to do is have a page that only displays if javascript is enabled(or similar) in the sense that it tells users that js is not enabled and how to enable, what were doing is creating web forms and would only like them viewable if js is enabled so that we can validate client side and reduce server load. Main reason is validation client side, cause if the initial form works well we will expand it to include forms for every type of job we can. No idea to where to start as js is not a strong point.

Cannot Move Focus To Control - Not Enabled

Jun 4, 2010

The following function() works fine on Chrome and Firefox but Internet F*C*I*G Explorer is showing a warning: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus. This function only load a few data into a SELECT, just that.

Code:
function cargarCanales() {
var ciudad = document.getElementById("ciudad").value;
var startTime = "<?php echo $startTime; ?>";
var endTime = "<?php echo $endTime; ?>";
cantCanales = getCanales(ciudad,startTime,endTime);

Up here works fine. If I check cantCanales with "alert" function I get a normal value.
for (i = 1; i <= cantCanales; i++) {
canal.options[i]=new Option(i, i);
}

Here everything is stopped, so I think that may be the problem is the "FOR" but how I said, on Chrome and Firefox everything works fine.
$("#canal").attr("disabled",false);
}
My SELECT.:
Code:
<select id="canal" name="canal"><option value="0">Select Channels..</option></select>

I call the function cargarCanales() from here:
Code:
$("#ciudad").change(function(){cargarCanales();});
When the select CIUDAD change, the cargarCanales function loads..
The full error message : [URL]

JQuery :: Button In IE Only Becomes Enabled When Move Mouse Over It

Aug 11, 2011

I have a jquery statement that enables or disables a button depending on whether a checkbox has been selected in a grid. This works fine in firefox but in IE the button is still displayed as disabled after checking the box. When you move the mouse pointer over the button is instantly becomes enabled. Showing an alert dialogue also makes the button display as enabled. Is there anyway to force IE to refresh the button display after running the statement?

Prevent Page From Loading If Java Is Not Enabled?

May 27, 2009

Is there any method which blocks the website from loading, if the browser using is not java script enabled? I have a webpage with some details to be entered. This website is designed in such a way that it checks the exceptions in the entry and alerts the user regarding it which is done using javascript. but for some users this feature is not working. I guess its the problem with the browser they use. So how can I alert them to enable Java by adding something to the script? Is there any way which prevents the page from loading if java is not enabled in the browser?

Test Whether A Client Has 3rd Party Cookies Enabled?

Jun 23, 2009

I want to be able to test whether a client has 3rd party cookies enabled.Inside site I have an iframe to another site that I (partially) control. [I dont control some of the javascript functions, and the HTML layout, but I do own most of the content and am the designer involved]. One of the things on this site [that I don't control] is a script that tests whether cookies are enabled or not. Since it is within an iframe, it is a 3rd party cookie and thus generates an error message in the form of an alert stating that cookies are not properly enabled. I want to be able to test to see if 3rd party cookies are enabled so that if they are not then I will not generate the iframe and instead display a phone number to contact else it will display the proper iframe.
