When browsing the web, it is often encountered that the IE browser cannot recognize JavaScript. This situation may cause a lot of inconvenience to users and also affect the functionality and user experience of the website. So, why does IE fail to recognize JavaScript, and how to solve it? Next, let’s discuss it together.
1. Why can’t IE recognize JavaScript?
1. The browser version is too low: The old version of IE browser does not have complete support for JavaScript, so it cannot recognize modern JavaScript syntax and features.
2. The security level is set too high: In order to protect computer security, some people will set the security level very high in the IE browser, which will cause the JavaScript in some web pages to fail to run.
3. Plug-in conflicts: Some plug-ins may conflict with JavaScript, causing IE to be unable to recognize and run JavaScript code.
4. Code errors: If there are errors in the JavaScript code itself, the IE browser may not be able to recognize and run it.
5. Cache problem: If there is a problem with the cache in the browser, it may also cause IE to be unable to recognize JavaScript.
2. How to solve the problem that IE cannot recognize JavaScript?
1. Update IE browser version: If you are using an old version of IE browser, you can try to update to the latest version. The new version has more complete support for JavaScript.
2. Lower the security level settings: You can lower the security level settings in the IE browser to allow JavaScript code to run.
3. Disable conflicting plug-ins: You can disable plug-ins that may conflict with JavaScript code in the IE browser to see if that solves the problem.
4. Check for code errors: Check the JavaScript code for errors. If there are errors, you can try to fix them.
5. Clear the browser cache: You can clear the cache in the IE browser and try to reload the web page to see if the problem can be solved.
As a developer, when writing web applications, avoid using JavaScript code that is not supported by IE, so as to ensure that it can run well in IE browser. In addition, when developing a website, you can also use some tools to test the compatibility of the website in the IE browser so that problems can be discovered and solved in a timely manner.
In short, IE not recognizing JavaScript is a relatively common problem, but there are many solutions you can try. I hope this article can help you solve the problem of IE browser not recognizing JavaScript.
