Angular Interview Practice

What is an example of an HTML attribute differing from its corresponding DOM property?

1. The class attribute vs the className property

2. The href attribute vs the target property

3. The value attribute vs the current value property in input elements

4. The style attribute vs the cssText property

The correct answer is: The value attribute vs the current value property in input elements

The example of the value attribute versus the current value property in input elements is a suitable illustration of how HTML attributes and their DOM properties can differ. In HTML, the value attribute specifies the initial value of an input field when the page is loaded. However, the current value property represents the actual state of the input field at any point in time. When a user interacts with the input element and modifies its content, the current value property updates to reflect these changes, whereas the initial value attribute does not change unless explicitly set. This distinction highlights the dynamic nature of the DOM, where properties can be modified after the page has loaded to reflect user interactions, while attributes remain static unless updated in the HTML markup. Understanding this difference is crucial for managing and manipulating form elements effectively in Angular and working with DOM elements in general.
