JavaScript — A Script To Check If Javascript Enabled With A Disabling Div

A Script To Check If Javascript Enabled With A Disabling Div

I am writing an administration panel for a web site. I want to check if the client’s browser javascript enabled and if it is not enabled, a warning DIV comes telling the client to enable javascript and disable the actual page (make the actual page non-usable). Is there a way to do that?

Thanks in advance

Hey guys, i’m trying to set up a favorite system for my website and I’m using ajax to do an async request to the server to run a php script.

The problem is that i’m running joomla with sef enabled. So whenever i’m on a page the URL looks like:

This obviously doesn’t work.

I followed this tutorial:

My question is how do i fix this.. can i get the base URL or something? I am a TOTAL noob to javascript. i somewhat understand it, but i have no clue what i’m doing. I just have basic programing knowledge through MATLAB and PHP.

BTW, the key here is not to leave the site

Thanks for the help in advance

Disabling Grab Scroll Script On Forms?

I’ve got this script working for grabbing and scrolling a website, and it’s perfect; the only problem is I’d like to disable it when clicking a form (basically, not being able to drag scroll when clicking inside a form or input tag). This could be either by specifying a class or ID, whatever works best.

This is the script, in case the website goes down or something:

 document.onmousedown = function() < var e=arguments[0]||event; var x=zxcWWHS()[2]+e.clientX; var y=zxcWWHS()[3]+e.clientY; document.onmousemove=function()< var e=arguments[0]||event; window.scroll(x-e.clientX, y-e.clientY); return false; >document.onmouseup=function() < document.onmousemove=null; >return false; > function zxcWWHS()

Also, would there be a way to enable grab scrolling just on the background? I mean, disabling it on images, text and any other element, and just leaving the empty spaces of the website with the ability to scroll.

Disabling Javascript

Ok I just gota ask. I read this originally and nearly killed my self laughing. then my brain got the best of me and my curiosity took over.

is it possible to write a javascript code that makes your web browser disable javascript?

is it even possible for Javascript to access a web browser in that sort of fashion? Like can a script have that much control? . or rather lack of control and self suicidal. but anyways

«error: Please Enable Javascript» — But It Is Enabled!!

a friend of mine has a problem on several (German) Legend of the Green Dragon (lotgd) servers.

Sometimes, mostly after she has loged in and out for a few times during a day, she suddenly gets the message that Javascript must be enabled to log in. But it definetely IS enabled — otherwise she’d never be loged in!

The error occurs
— on 2 different PCs
— with 2 different internet providers
— with IE, FF and Opera
— only on lotgd servers — any other page using Javescript are working fine

We
— updated and downgraded Javascript
— disabled and/or uninstalled all antivirus and firewall programms
— cleaned cache with CCleaner
— disabled browser add ons
— reinstalled Windows
— disabled auto-insert passwords

Even a reboot doesn’t change anything. Sometimes, when she waits a few hours, she can log in again. Sometimes the error doesn’t occur for days, sometimes it’s there every day.
That’s why it is so strange. Although she doesn’t change anything, the error comes and goes completely irregular.

The games’ admins can’t or don’t want to help, they say that she’s the only one with that problem and that it’s not a mistake in the script.

What might occur that error? And what can we do to stop it??

That’s what the Opera error console says:

Html test if javascript is enabled code example

When JavaScript runs, you just add a class to the body which will show the elements with additional CSS Selectors. How to handle disabled JavaScript in browser? When JavaScript is disabled, Just tried to redirect to some page where we can display the message that Javascript is disabled.

How to display content if js is enabled [duplicate]

A simple way to achieve that would be to hide by default your divs and display them with js.

document.querySelectorAll('.js-only').forEach(x => x.classList.add("show"))

There is nothing you can do in just pure HTML/CSS. You will need to set the elements to be hidden by default with CSS. When JavaScript runs, you just add a class to the body which will show the elements with additional CSS Selectors.

document.body.classList.add("js-enabled");

.js-block, .js-inline < display: none; >.js-enabled .js-block < display: block; >.js-enabled .js-inline

I would assume you are trying to see if you can display specific javascript elements or not. I would recommend just using the noscript tag but if you want to check it you can use a .no-js class on the body and create non javascript styles based on .no-js parent class to seperate them.

If javascript is disabled you will get all the non javascript styles you added, if there is JS support the .no-js class will be replaced giving you all the styles as usual.

 document.body.randomClassName = document.body.randomClassName.replace("no-js","js"); 

But I would recommend just a redirect or alert that says that they should enable javascript if they ever want to browse a website to the fullest 🙂

How to detect JavaScript is disabled in browser? 

As we know, tag is used for JavaScript. Same way there is tag which gets in action when the JavaScripts disabled in browser.

How to handle disabled JavaScript in browser?

When JavaScript is disabled, Just tried to redirect to some page where we can display the message that Javascript is disabled. There is meta tag in HTML named “meta refresh” which will redirect the user to another page in the interval specified in that header.

As, we can see above code inside noscript, there is “meta refresh” tag with interval of “0″ second. As, the JavaScript is disabled in that page, the browser gets redirected to “ShowErrorPage.html” to show some warning message.

I hope this will help you.

You are right . The tag is used to show only if JavaScript is disabled. In order to test this , do the following:

• Save this snippet in a file «test.html».
• Open it with your brower.
• Enable/Disable JavaScript (In FireFox this is here: Tools/Options/Content/Enable JS).

As you can see, you can put any HTML inside the tag that you would put inside the body of a page.

  
Simple Example Page
     

is not a good solution as IE11 (and previous) have a security option that when set to ‘high’ disables both Javascript and Meta Refresh Tags!

The best solution I have found to handle this case is :

  body < position:relative; >.noscript < width:100%; height:100%; /* will cover the text displayed when javascript is enabled*/ z-index:100000; /* higher than other z-index */ position:absolute; >.noscript #div100

How to Display a Message if JavaScript is Turned Off

Many websites depend on JavaScript to function well. Your site may not be accessible if it is turned off. However, many users disable the JavaScript on their browsers for security concern. That’s why you need to make sure that your website will still work well even with JavaScript disabled. Besides, all validation must be duplicated on both client and server-side so you can catch things in case the JavaScript is turned off.

If you have content that will not function without JavaScript, you need to display a message with an explanation of the problem. In this snippet, we are going to have a look at 2 simple methods to display the content when JavaScript is turned off.

HTML tag

Here’s the above code piece in action:

html> html> head> title>Title of the document title> head> body> script> document.write("Welcome to W3Docs") script> noscript> Your browser doesn't support JavaScript noscript> body> html>

HTML tag has an alternative content, which is displayed in the browsers, that don’t support scripts, or the browsers, where the script support is disabled by the user. In other cases, the browser ignores this tag and its content.

The meta refresh Method

Many developers suggest another method to display the content when JavaScript is turned off. You need to redirect to a page, where you can show the message that JavaScript is turned off. In order to do that, you can use the method. Here is how it looks like:

As you see in the code above, the JavaScript is disabled in that page, the browser gets redirected to “ShowErrorPage.html”, where it will show a warning message.
