When copying and pasted web content, one would often encounter some hidden code that might affect reading and operation. Here are some ways to remove this hidden code for better reading and operation: 1 Use the "Review Elements" function of the browser: Open the browser and select "Tools">"Review Elements". In the pop-up window, select the "content" tab, enter "*" in the "auto-complete" text box, and then click "OK". This way, the browser will show you all the elements that contain hidden code. You can look at their source code one by one to find the hidden code and remove it. 2. Use the browser's "Clear Form" function: Open the browser and choose "Tools">"Internet options">"General">"Remove Form Data". The browser will clear all the content filled in the form, including hidden code. 3 Use the browser's "edit element" function: Open the browser and choose "Tools">"edit element">"Clear code". This way, the browser will show all the source code of the element. You can look at them one by one to find the hidden code and remove it. 4. Use programming tools: If you are familiar with programming languages, you can use programming tools (such as VS Code, ChromeDevTools, etc.) to view and modify the source code of the webpage to find hidden code and remove it. It should be noted that different browser and programming tools may have different methods and functions. You can choose the appropriate method to solve the hidden code problem according to the actual situation.
