Editor to share with you what the meaning of the web page undefined means, I hope you will gain something after reading this article, let's discuss it together!

Web page undefined means that there is an unknown error on the page. It is suggested that undefined is not defined correctly or converted incorrectly when developing a website, or that undefined does not define this error until it cannot find the definition.

Undefined refers to an unknown error on the page, which indicates that undefined is not defined correctly or converted incorrectly when developing a website, or that undefined does not define this error until it cannot find the definition.

Undefined is a special value that is usually used to indicate that a variable has not been assigned a value. A reference to an undefined value returns a special value. In fact, most computer languages have only one value for "none", for example, C language NULL,Java language null,Python language None,Ruby language nil.

Generally speaking, there are only two aspects of undefined problems, namely, the website server and the browser local problem. It is recommended to take a look at the page source code, if the source code is also undefined, it means that the page is like this, this belongs to the website server problem.

The correct solution to the appearance of undefined on a web page:

1. Press "F5" on the keyboard to refresh and open the page. If there is still a "undefined" error, then the browser faked death, or the program crashed. Let's copy the Baidu URL of this post bar.

2. Close the current browser, reopen the browser, paste the Baidu URL that just copied the post bar and visit it. The problem is that Baidu has received the check-in command, but the feedback to the web page has been interrupted, so our page has a "undefined" error, which is the responsibility of the browser.
