FAQs on HTML attribute vs dom property Video Lecture - Angular 2 tutorial - Front-End Programming

1. What is the difference between an HTML attribute and a DOM property?
Ans. HTML attributes are defined within the HTML markup and provide initial values for an element's properties. On the other hand, DOM properties are part of the Document Object Model and represent the current state of an element. While attributes are static, properties can be modified dynamically using JavaScript.
2. Can I change an HTML attribute using JavaScript?
Ans. Yes, you can change HTML attributes using JavaScript. By accessing the element's attributes property, you can modify the value of an attribute. However, it's important to note that changing an attribute does not always reflect an immediate change in the DOM property.
3. Are HTML attributes case-sensitive?
Ans. In general, HTML attributes are not case-sensitive. This means that you can use lowercase or uppercase letters interchangeably when specifying an attribute. However, there are exceptions to this rule, such as the "class" attribute, which is case-sensitive.
4. When should I use HTML attributes and when should I use DOM properties?
Ans. HTML attributes should be used when initializing an element's properties with static values that don't need to be modified frequently. On the other hand, DOM properties are more suitable for dynamic changes to an element's state, especially when interacting with JavaScript.
5. Can I access an HTML attribute using JavaScript?
Ans. Yes, you can access HTML attributes using JavaScript. By using the getAttribute() method, you can retrieve the value of a specific attribute for an element. This can be useful when you need to retrieve or manipulate specific attribute values in your JavaScript code.
