How to Give Single Quote in Javascript
In this tutorial, you will learn how to give single quote in javascript. When there are quotations inside other quotations, we mark the phrase with a single quote. For a newbie developer, it can be a bit tricky to give single quote in a string.
There are numerous ways to give single quote in a string. But for the sake of simplicity, we will make use of template string which helps in creating a dynamic string by using variables in it. You can also use backslash (\
) escape character to escape quotes in a string.
In the following example, we have one global variable that holds a string. Upon click of a button, we will give single quote in the string and display the result on the screen. Please have a look over the code example and the steps given below.
HTML & CSS
- We have 3 elements in the HTML file (
div
,button
, andh1
). Thediv
element is just a wrapper for the rest of the elements. - The
innerText
for thebutton
element is“Add”
and for theh1
element, it is“Result”
. - We have done some basic styling using CSS and added the link to our
style.css
stylesheet inside thehead
element. - We have also included our javascript file
script.js
with ascript
tag at the bottom.
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <link rel="stylesheet" href="style.css"> <title>Document</title> </head> <body> <div class="container"> <button>Add</button> <h1>Result</h1> </div> <script src="script.js"></script> </body> </html>
.container { text-align: center; } button { margin-top: 10px; padding: 10px 20px; }
Javascript
- We have selected the
button
element andh1
element using thedocument.querySelector()
method and stored them inbtnAdd
andoutput
variables respectively. - We have a global variable
myString
which holds a string as its value. We are using backslash escape character to escape single quote in the string. - We are displaying
myString
in theh1
element usinginnerText
property. - We have attached a
click
event listener to thebutton
element. - In the event handler function, we are calling
addQuotes()
method and passingmyString
as a parameter. In this method, we are adding single quotes to the string dynamically using template literal and returning it. - We are storing the final string in the
result
variable. - We are displaying the
result
in theh1
element using theinnerText
property.
let btnAdd = document.querySelector("button"); let output = document.querySelector("h1"); let myString = `One day earth\'s atmosphere will be inhabitable.`; output.innerText = myString; btnAdd.addEventListener("click", () => { let result = addQuotes(myString) output.innerText = result; }); function addQuotes(str){ return `'${str}'`; }
