How to Write Double Quotes in Javascript

By Krishnaa JavaScript Questions 0 Comments

In this tutorial, you will learn how to write double quotes in javascript. For direct citations within a sentence, use double quotation marks. Any time someone else’s work or verbatim spoken words appear in a book or speech, it is known as a direct quotation. For a newbie developer, it can be a bit tricky to write double quotes in a string.

There are numerous ways to write double quotes 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 write double quotes 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, and h1). The div element is just a wrapper for the rest of the elements.
The innerText for the button element is “Add” and for the h1 element, it is “Result”.

We have done some basic styling using CSS and added the link to our style.css stylesheet inside the head element.
We have also included our javascript file script.js with a script 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 and h1 element using the document.querySelector() method and stored them in btnAdd and output variables respectively.
We have a global variable myString which holds a string as its value. We are using backslash escape character to escape double quotes in the string.
We are displaying myString in the h1 element using innerText property.

We have attached a click event listener to the button element.
In the event handler function, we are calling addQuotes() method and passing myString as a parameter. In this method, we are adding double 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 the h1 element using the innerText property.

let btnAdd = document.querySelector("button");
let output = document.querySelector("h1");

let myString = `He said \"Move on!\"`;
output.innerText =  myString;
 
btnAdd.addEventListener("click", () => {  
  let result = addQuotes(myString)
  output.innerText = result;
});

function addQuotes(str){
 return `"${str}"`;
}
