How to Set Default Values for Input Fields Using JavaScript?

Determining Input Field Default Value in JavaScript

In web development, setting the default value of an input field can greatly enhance user experience. One way to accomplish this in JavaScript is to utilize the value property of the HTMLInputElement interface.

The syntax for setting the default value is:

document.getElementById("fieldID").value = "Default Value";

For example, consider the following input field with the HTML ID "name":

<input type="text">

Using JavaScript, you can set the default value of this input field to "John Doe" like so:

document.getElementById("name").value = "John Doe";

When the user opens the page, the input field will display "John Doe" as its default value. They can then edit or replace this value as needed.

This method is a straightforward and effective way to set default values for input fields using JavaScript. It's particularly useful when you want to prefill certain form fields with specific information to guide or assist the user.
