IE11 cannot start JavaScript

With the continuous development of network technology, JS (JavaScript) has become one of the most important languages ​​​​in WEB front-end development. In WEB front-end development, JS is used very frequently, so it is very important for WEB developers to master the JS language. However, when using the IE11 browser, sometimes JS cannot be started, which affects the developer's work efficiency. This article will introduce in detail the problem of JavaScript not being enabled in IE11 browser and provide solutions.

Why can't IE11 start JavaScript?

There are many reasons why the IE11 browser cannot activate JavaScript, as follows:

1. The browser version is low.

In the IE11 browser, JavaScript version support is closely related to the browser version. If the browser version is too low, it is likely that a higher version of Javascript will not be supported. Therefore, when developers cannot activate JavaScript in the IE11 browser, the first thing they need to consider is whether the version of the IE11 browser is too low.

2. Security settings are too high

The IE11 browser is a highly secure browser released by Microsoft, and this is a common reason why JavaScript cannot be started. The IE11 browser has strong security enabled by default, such as disabling "ActiveX control" and other functions, causing some JavaScript programs to fail to run.

3. Plug-in conflict

The installation of some plug-ins in the IE11 browser will also cause JavaScript to fail to start. Many plug-ins will modify the registry information of IE11 when installed, thus affecting the operation of JavaScript. If there is a plug-in conflict in the IE11 browser, JavaScript cannot be started.
