HTMLInputElement: select() method

The HTMLInputElement.select() method selects all the text in a element or in an element that includes a text field.

Syntax

Parameters

Return value

Examples

Click the button in this example to select all the text in the element.

HTML

input type="text" id="text-box" size="20" value="Hello world!" /> button onclick="selectText()">Select textbutton> 

JavaScript

function selectText()  const input = document.getElementById("text-box"); input.focus(); input.select(); > 

Result

Notes

Calling element.select() will not necessarily focus the input, so it is often used with HTMLElement.focus .

In browsers where it is not supported, it is possible to replace it with a call to HTMLInputElement.setSelectionRange() with parameters 0 and the input’s value length:

input onClick="this.select();" value="Sample Text" /> input onClick="this.setSelectionRange(0, this.value.length);" value="Sample Text" /> 

Specifications

Browser compatibility

BCD tables only load in the browser

How to Select All HTML Textarea Text on Click Using JavaScript?

You can select all text in an HTML element in the following ways:

Select All Textarea Text When It’s Clicked On

To select all text in an HTML element when it’s clicked on, you can use the HTMLTextAreaElement.select() method, for example, in the following way:

Alternatively, you may use the HTMLTextAreaElement.setSelectionRange() method to achieve the same:

If you do not wish to inline JavaScript, you may create an event handler function for the click event, for example, like so:

const textarea = document.getElementById('foo'); textarea.addEventListener('click', function (e) < e.target.select(); >);

Or, alternatively, you can do the same using HTMLTextAreaElement.setSelectionRange() , for example, like so:

const textarea = document.getElementById('foo'); textarea.addEventListener('click', function (e) < const target = e.target; target.setSelectionRange(0, target.value.length); >);

You will have to replace » foo » with the value you assign to the id attribute of the element.

Select All Textarea Text When a Button is Clicked

Consider you have the following and a «select all» element:

You could implement the » selectAllText() » function (which is called when the button is clicked) as follows:

Or, alternatively, you could use HTMLTextAreaElement.setSelectionRange() to achieve the same:

Calling HTMLElement.focus() is important as just using HTMLTextAreaElement.select() (or HTMLTextAreaElement.setSelectionRange() ) will not necessarily focus the textarea.

How to Select All Text in HTML Text Input When Clicked Using JavaScript

It is pretty simple to select whole text on just a single click. You can use the following JavaScript code snippet:

html> html> head> title>Title of the Document title> head> body> div> Input Text: input onClick="this.select();" type="text" value="Sample Text"> div> body> html>

However, it does not work on mobile Safari. In such cases, you can use:

html> html> head> title>Title of the Document title> head> body> div> Input Text: input onClick="this.setSelectionRange(0, this.value.length)" value="Sample Text" /> div> body> html>

The HTMLInputElement.select() method selects the entire text in a element or element that includes a text field.

But it becomes impossible to place the cursor at a desired point after focus. Here is another solution that combines all text selection on focus and as well as allows selecting a specific cursor point after focus:

html> html> head> title>Title of the Document title> script> head> body> div> Input Text: input id="input-tag" value="Sample Text" /> div> script> const inputElement = document.getElementById('input-tag'); inputElement.addEventListener('focus', function(e) < inputElement.select() >) script> body> html>

The HTMLElement.focus() method sets focus on the given element if it can be focused. By default, the focused element will receive keyboard and similar events.

Selecting the all text in HTML text input using JavaScript

In this tutorial, we are going to learn about how to select all text entered in an HTML input (field) when a button is clicked using JavaScript.

Consider, we have the following html input field, button element.

input id="place" value="King towers" /> button id="select">Select Textbutton>

To select all text present inside a text input field when a button is clicked, first we need to access the above two elements inside a JavaScript by using the document.getElementById() method.

const input = document.getElementById("place"); const btn = document.getElementById("select");

Now, we need to attach a click event listener to the btn element, inside that we can select the input text by using the input.select() method.

btn.addEventListener("click",()=> input.select(); // it selects the text >)

We can also select all text in an input field by clicking on the input field itself.

input id="place" value="King towers" onclick="this.select()" />

Similarly, we can use the input.setSelectionRange() method by passing 0, input.value.length as an first and second arguments.

const input = document.getElementById("place"); const btn = document.getElementById("select"); btn.addEventListener("click", ()=> input.focus(); // it focusses the text input.setSelectionRange(0, input.value.length); >)
