What is javascript?
JavaScript can be called a multi-paradigm language. It has support for many ways of programming. For example, object-oriented, functional and imperative.
This type of programming is not directly related to java in any way. The main syntax of this programming language is the C language, as well as C++.
The basis of browser web pages is HTML code, with the help of which programmers add various interactive elements to pages.
If javascript is disabled in the browser, interactive elements will not work.
This type of programming language appeared thanks to the joint work of Sun Microsystems and Netscape.
JavaScript was originally called LiveScript, but after Java language became popular among programmers, the development companies decided to rename it.
Netscape's marketing department thought that such a name would increase the popularity of the new programming language, which, in fact, happened.
Recall that JavaScript is not directly related to Java. They are completely different languages.
JavaScript features
This programming language has an unlimited number of possibilities due to its versatility.
The main aspects of application are mobile applications for smartphones, interactive web pages of sites and services.
Most of the innovation came from joining the project with AJAX, which provided the features used in the language today.
To save traffic and increase ease of use, JavaScript provides the ability to change the pages of sites and services in small parts without the user noticing online.
This does not require the site to be offline while editing or adding new information.
Changes happen immediately without requiring a refresh or page reload.
The JavaScript feature can be disabled for various reasons.

Therefore, for the correct operation of sites, it is often recommended to enable this function in your browser.
Javascript is a universal programming language.
With it, almost all modern websites and services are able to provide GIF animation, as well as clickable links and attachments.
JavaScript also allows you to correctly use flash-games and applications, for example, VKontakte games.
But having an activated function is not enough for this.
The computer system must have latest version programs Adobe Flash player.
In other cases (for example, browser games), the presence of a flash player may be optional.
VIDEO: How to enable JavaScript - detailed instructions
In laptops, the touchpad replaces a regular computer mouse. For each user, the convenience of the touchpad is a relative concept. One is easier to use a mouse, but with a laptop you have to carry a mouse. Moving the cursor using the touchpad is convenient in its own way, but sometimes there are situations when the touchpad stops working. There are several ways to fix this problem.
How to enable the touchpad using reboot
Often in interruptions with the operation of various computer functions, a simple reboot of the device helps. This is the easiest and fastest way to check if your TouchPad is working. After restarting, the touchpad functions in its normal mode.
To restart the laptop, temporarily connect a computer mouse. If this is not possible, you will have to use the keyboard.
Restart can be done in several ways:
- Press the key combination Alt + F4, then use the arrows to select the restart function
- Activate the Windows (Win) button - use the arrows to reach "Start" - select "Shut down" - press "Enter"
- Press Ctrl + Alt + Delete - "Shut down".
If the problem has not been resolved, you should move on to other methods to fix the error.
Enable TouchPad via hotkeys
All laptops are equipped with quick functions for turning on Wi-Fi, changing brightness, volume, including turning on the TouchPad. They are located on the keys from F1 to F12. They work in combination with the Fn button. On the keyboard, the touchpad enable function is depicted as a video icon with a crossed-out touchpad and a hand next to it.
Each laptop manufacturer sets different numbers by default. In the table below, we will show some examples of using keyboard shortcuts on different brands of laptops.
TouchPad setup via BIOS
All laptop components are controlled through the BIOS system. The operation of the TouchPad is no exception, so it can be enabled in this way.
To do this, follow these steps:
- Restart your laptop
- During power on, press the "Delete" or "F2" key
- Find the "Advanced" tab
- Go to the "Internal Pointing Device" section
- Set to "Enabled"
- We save the changed settings with "F10" and "Y".
Important: the names of sections and parameters in the BIOS differ depending on its version, so it is better to read the instruction manual for your laptop model on the official website of the manufacturer.
Enable Synaptics Touchpad
Some laptops come with Synaptics touchpads. It has advanced settings to enable and disable the TouchPad. To check the operation of the sensor, go to the "Control Panel":
- Section "Hardware and sound"
- Subsection "Mouse"
- Device Settings or ELAN tab
- Enable button
- Save the configuration by clicking OK.
There may be a ClickPad function in the mouse properties. It activates the touchpad, which automatically turns off when a mouse is connected. If you notice such a relationship, enable this function in the mouse options. In the case when the power button is not active, the error should be corrected in another way.
Reinstalling drivers
From time to time drivers need to be updated or reinstalled. There can be many reasons for the “rally” of drivers. If none of the methods helps to solve the problem with the inclusion of the touchpad, refer to the help of the drivers. All drivers are available on the manufacturer's official websites.
Tip: when downloading drivers, be sure to pay attention to the laptop model, Windows version and bit depth (x86 (x32) or x64).
The best outcome is when all parameters match. But there are non-essential options, such as how Windows version which do not significantly affect. In any case, there should be a match.
Automatic installation may not work. In this case, try installing the drivers manually:
- Control Panel
- Device Manager
- In the "Mouse" section, find the touchpad
- Open "Properties" via RMB
- The device status should indicate: "The device is working properly"
- Go to Driver tab
- First, click "Rollback", then "Update", if it did not help
- In the window that opens, select manual search and installation of drivers
- Specify the path to the drivers and click Next.
Important: do not forget to restart your computer immediately after installing the drivers, and then check the operation of the TouchPad.
After the reboot, the touchpad should work. If this does not happen, most likely the reason is mechanical damage. This may be damage to the cable, or the panel itself. There may be many options, so contact the service center for help.
Conclusion
Touchpad malfunction is a common problem for laptop users. Fortunately, there are several ways that can solve this issue. Try to perform all the methods in turn, starting from the simplest. In most cases, it does not come to installing drivers.
Nowadays, almost all web pages use JavaScript, a scripting programming language that runs on the visitor's web browser.
JavaScript is a scripting language that can be used to embed small programs into an HTML document (website page) that make it easier to work with an HTML page and make it more beautiful.
Therefore, in order to see the pages of sites colorful, with the full range of functionality, you must enable JavaScript in your browser.
Accordingly, if avaScript is disabled for some reason, the content or functionality of the web page may be limited or not possible at all.

Brief information about the use of JavaScript, in various versions of web browsers.
JavaScript is not supported by: text-based browsers like Lynx, w3m, Links, old versions of desktop browsers Netscape Navigator, Internet Explorer; browsers in most models mobile phones: Opera Mini, NetFront, Bold, Minimo, Doris, as well as some graphical browsers: Amaya, DittoB. JavaScript is partially supported by the text browser eLinks(at the level of simple scripts). In some browsers, on the contrary, the ability to disable JavaScript execution through the user interface is missing, for example, in Google Chrome up to version 10.
The JavaScript option is enabled in all modern web browsers: Internet Explorer, Opera, Firefox, Safari, Chrome, by default, i.e. when installing the browser in the operating system. JavaScript is disabled for the following reasons: when the browser is used by several users with different views on web surfing, during software updates, when blocked by security programs: antiviruses, antitrojans, anti-advertising.
It should be noted that Java Script blocking can be caused by the use of firewalls (firewalls, firewalls), proxy servers, anonymizers. In these cases, changing the JavaScript option policy needs to be done, not in the browser, but in those programs. Often, messages about disabling JavaScript arise due to incorrect settings of web servers or the use of rare versions of JavaScript and frameworks on pages, it is worth informing the administrator of a similar site about this. It is extremely rare that a script execution failure occurs when the JavaScript interpreter program code in the operating system is damaged; a solution to such a problem is possible only by involving a highly qualified specialist.
Note that some users disable Java and JavaScript in their browsers on purpose. This is due to the fact that, firstly, the execution of scripts and applets written in these languages slows down the unloading of web pages, and secondly, scripts and applets can be used by intruders to inject malicious code of viruses, trojans, worms into the operating system. system. Disabling JavaScript "s, for such users, is the acceleration of the browser, protection from hacker hacking.
Note A: Java and JavaScript are two different programming languages, the permission to use them is separated in the settings of web browsers. JavaScript code interpreter, installed in all modern operating systems Oh. But the Java platform, for some operating systems, if Java programs are required, you will have to download and install from the official site.
