How to detect if JavaScript is disabled

Detect if JavaScript is Disabled in a Browser & Show Message

Some users may have JavaScript disabled for various reasons, such as security concerns or personal preferences. As a website owner, it’s important to ensure that your website is accessible to all users, including those with JavaScript disabled.

In this post, we will explore how to detect if JavaScript is disabled in a web browser and how to show fallback content or message on the web page if it is disabled. It will help them to understand why some functionalities are not working on your website.

How to Detect If JavaScript is Disabled

The HTML tag is used to detect if JavaScript is disabled in a browser. This tag functions as a means to manage situations where the browser is able to recognize the tag but does not support JavaScript. It can provide an alternative message to users.

You can wrap some content in the tag to display them in front of the users who have disabled JavaScript in their browsers. In this way, you can tell them to enable it.

In this example, I am using the tag with a message. If JavaScript is disabled, browsers will not be able to download and execute the main.js file. In this situation, users will see that message.

You can add any HTML contents you want in between this tag. Browsers will only display the contents when they don’t support the tag. That’s how you can ask your users to enable JavaScript in their browsers.

Conclusion

Modern websites are highly dependent on JavaScript. Many times users may not know that JavaScript is disabled in their web browsers. If they visit your website and find that it is not working properly, they will think it is your website’s problem.

When you detect whether JavaScript is disabled or not and provide an alternative message or content to users who do not have JavaScript enabled in their browsers, it will give them a better user experience.

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.

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.

Show message if javascript disabled on client side using noscript tag

I want to flag a message if javascript is disabled at client side. I searched here and found tag to use for handling this stuff.

I did this at w3schools editor to check but its not working let me know if this is not meant for this or something else I am missing in this part ?

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 

is meant for this kind of thing, just as is meant for JS. Be aware that using the meta tag refresh:

means that this is easily disabled in IE (IE10 at least) by increasing the Internet Options Security (which was probably used to disable the JS in the first place). The «allow META REFRESH» option is disabled when the security setting is increased.

How to Display a Message if 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:

Message that the user has JS disabled

I want to prepare a message for my users in case he/she has JS disabled. First of all I want to clarify that I will not make the site work without JS(it requires considerable coding work.)

The question is OK. I detect that the user has not enabled JS. What are the next steps from there?What warning should I give him/her? Should I do anything else besides warning them? Redirecting them for example somewhere else or taking any other action for that matter. I really do not know how to handle this besides showing the message of course.

Explain why

People with JavaScript disabled are certainly aware of their settings, a warning message will not come as a suprise. Bear in mind that some users do so for privacy concerns . If you want people to enable it back, you need to earn their trust first . Explain why your website requires Javascript and what kind of people are behind it, what are their motives. Mention that the website does not run any tracker, if it is the case.

Provide an overview

Some users will come by chance, their initial quest is to check if the website can offer something of value for them. You need to provide a non-js usable home page to help them get their answers. If they are interested, they will come back later with Javascript activated.

A last advice: don’t explain how to activate it

Because most of the time disabling javascript was done on purpose and it rushes users to do something when they have not built any trust yet.

For websites that are fully dependant on JS I recommend to create two DIVs.

1. Background — make background content (content with lower z-index) unreadable.
2. Message — a message clearly stating that this website is not going to work without JS.

Take a look at quora when trying to read other articles without signing in.

This is what the effect looks like:

This is easily achievable with plain CSS, so should have no problems. Remember however that being so struck about this might drive your users away.

In the same line as @asiegfried, I think that the relevant part is not that JS is disabled, but that the site won’t work.
«JS disabled», out of the blue, is not normal-people-friendly.
My idea is a message like

«Your current browser configuration is not compatible with this site (JavaScript disabled)»

For most people this will be enough.
For the others, provide a [?] help link to an HTML page explaining the issue in detail, and providing instructions for those who want to change the configuration.
In the instructions, don’t make the user tell which browser are they using. Ideally, you tell them (make and model), because some people might not be sure, and because you already know it.
In that page you can communicate them that you don’t intend to do any harm, neither collect information about them.

How to Display a Message if JavaScript is Turned Off

HTML tag

When JavaScript is disabled, you can use the tag to display a warning message and hide the entire content with CSS. It looks like this:

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:

The meta refresh method consists of HTML tag with the http-equiv parameter set to «refresh» and a content parameter giving the time interval in seconds, so this will redirect the user to another page in the interval specified in that header. By setting the refresh time interval to zero (or little value), meta refresh can be used as a method of URL redirection.

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.
