This slide explains the different methods for accessing and manipulating the content of elements in the DOM. It discusses three main methods: 1) Inner HTML, which allows for both text manipulation and adding HTML tags, but must be used carefully due to security risks. 2) Inner text, which deals only with visible text and is useful when working with readable text, excluding hidden elements or HTML tags. 3) Text content, which includes hidden text and is safer for text manipulation as it doesn't parse HTML tags or get affected by CSS styling. The choice between these methods depends on specific needs, such as manipulating or retrieving text, including HTML structure, or ensuring security with user-generated content. Understanding the differences between these methods is important for effective and secure DOM manipulation. This slide focuses on the different methods of accessing and manipulating the content of elements in the DOM. Understanding these methods is key to interacting with the content of web pages dynamically. 1. Enter HTMLs. This property is used to get or set the HTML content of an element. It allows not only text manipulation, but also adding HTML tags and structure. However, it should be used with caution due to potential security risks like cross-site scripting attacks when using user-generated content. 2. Inner text. Inner text is used to get or set the visible text content of an element. It differs from inner HTML in that it only deals with visible text. This property is useful when you need to work with the readable text of an element, excluding any hidden elements or HTML tags. 3. Text content. The text content property is used to get or set the text content of an element, including text that may be hidden, such as script or style elements. It is a safer alternative to inner HTML for text manipulation as it does not parse HTML tags and is not affected by CSS styling. These methods provide different levels of control over the content of DOM elements. Choosing between them depends on your specific needs, such as whether you need to manipulate or retrieve only text, include HTML structure, or ensure the security of user-generated content. Each method has its use cases and understanding their differences is essential for effective and secure DOM manipulation.
