The provided HTML code utilizes the input, form, and output elements to create a simple form that takes user input and displays the result dynamically.
Here's a breakdown of the code:
Explanation:
1. Input Elements (input):
• Two input elements are present with the ids "a" and "b." These are used to take user input as numbers. The type="number" attribute ensures that users can input only numeric values.
2. Form Element (form):
• The form element has an oninput attribute, which specifies a JavaScript expression to be executed when the user input changes. In this case, the expression is x.value=parseInt(a.value)+parseInt(b.value). This expression is triggered whenever the user inputs change within the form.
3. JavaScript Expression:
• The JavaScript expression takes the values of "a" and "b," converts them to integers using parseInt(), adds them together, and then assigns the result to the value attribute of the output element with the name "x." This means that the sum of "a" and "b" will be dynamically displayed in the output element as the user inputs change.
4. Output Element (output):
• The output element is used to display the result. It has the name attribute set to "x," and the for attribute specifies that it is associated with the "a" and "b" input elements. The initial value of the output element is set to "0."
This setup allows users to enter numeric values in the "a" and "b" input fields, and as they do so, the sum of these values is dynamically updated and displayed in the associated output element.
