Have no idea about how to create a Javascript textbox? This instruction belows can be of many use to you somehow.
Jump right in for more details!
What Is A Javascript Textbox?
The JavaScript TextBox, so-called text field, is a control used to modify, display, or enter plain text on forms in order to get user email addresses, names, phone numbers, and other information.
There are several advances in this control compared to that of the original HTML5 TextBox, including floating labels, icons, grouping, various sizing, validation statuses, and more.
HTML5/CSS and JavaScript versions are currently available for you to work in the CGI interface.
Create A Javascript Textbox
Here is what you should do to create the JavaScript textbox:
- Step 1: To generate an <input> element, you must first employ the createElement(“input”) feature of the document object.
- Step 2: After that, employ the Element.setAttribute() feature to set the <input> element’s type attribute you’ve created before into “text”.
Be careful to work with these utilities. Otherwise, it could lead to serious errors that cost you dozens of times! Let’s check out the code example below!
Running the code:
<!DOCTYPE html>
<html>
<title>Javascript Textbox</title>
<body>
<h2>Create Textbox element using JavaScript</h2>
<script>
const input = document.createElement("input");
input.setAttribute("type", "text");
document.body.appendChild(input);
</script>
</body>
</html>Output:

The HTML document resulted:
<body>
<h2>Create Textbox element using JavaScript</h2>
<input type="text">
</body>
Getting Data From A Textbox Using JavaScript
Little did you know that you can gain at least two distinctive approaches to receiving data in a textbox. Scroll down to learn more!
By ID
ID, one of the essential Javascript functions, must not be any strange for those who are familiar with JavaScript. The good news is: that you can also adopt this straightforward feature to retrieve the textbox’s contents!
However, we’d have to make some adjustments to our form first. In order for us to be able to utilize the method, you must add one more property to the textbox, which is ID. Let’s say we want to refer to myTextBox as an id. This is how the textbox element would appear:
<input type="text" name="inputbox" value="" id="myTextBox">The rest of the HTML file remains unchanged. The Javascript code, on the other hand, would be significantly altered. It would like the following code snippet:
function showData (form) {
var showData= document.getElementById("myTextBox");
alert ("Your Data: " + dataRcv);
}
The difference is that we now implement the getDocumentById() method instead of the dot operator.
By Searching through the elements of the form.
In this approach, you will need to head toward the form that contains the textbox and search through the form’s components for the textbox’s value. The code snippet would be as follows:
var showData = document.getElementById(“myForm”).elements[1].value;
Setting A Value In A Textbox
To access or set the value contained inside the textbox, the value attribute of the input element may be of benefit.
For instance, put any word into the textbox and then retrieve the value:
const usernameText = document.getElementById("username");
const value = usernameText.value;
console.log(value); // your textbox value
// You can also enter the value this way:
const usernameText = document.getElementById("username");
usernameText.value = "Nathan";That’s how you acquire or get a textbox’s value property.
Conclusion
The steps to open a Javascript file are listed above. Hopefully, you’ll be able to wind up some more useful information. Wish you the best of luck!
