javascript onclick alert are you sure

Javascript onclick Alert "Are you sure?"

If you are a web developer, you must have come across situations where you need to ask the user for confirmation before proceeding with an action. One of the most common ways to do this is by using JavaScript's "onclick" event and an "alert" message that asks the user if they are sure they want to proceed.

The Code

Here is an example code snippet that demonstrates how to use JavaScript's "onclick" event with an "alert" message:

<button onclick="myFunction()">Click me</button>

function myFunction() {
  if (confirm("Are you sure you want to proceed?")) {
    // User clicked "OK"
  } else {
    // User clicked "Cancel"

The above code creates a button element that triggers the "myFunction()" JavaScript function when clicked. The function checks if the user wants to proceed by displaying an "Are you sure?" message using the "confirm" function. If the user clicks "OK", the code inside the "if" block is executed. If the user clicks "Cancel", the code inside the "else" block is executed.

Alternative Approaches

There are multiple ways to achieve the same result. Here are a few alternative approaches:

  • Using a separate confirmation function: Instead of using a "confirm" message inside the "onclick" event, you can create a separate function that displays the message and returns a boolean value indicating whether the user wants to proceed or not. You can then call this function inside the "onclick" event. This approach can make your code more modular and reusable.
  • Using a custom modal dialog: Instead of using the browser's built-in "confirm" message, you can create a custom modal dialog using HTML, CSS, and JavaScript. This approach gives you more control over the look and feel of the message and can provide a better user experience.
  • Using a third-party library: There are many third-party libraries available that provide pre-built dialog boxes with customizable options. These libraries can save you time and effort and provide a consistent user experience across your website.


Asking the user for confirmation before proceeding with an action is a common requirement in web development. By using JavaScript's "onclick" event and an "alert" message, you can easily implement this functionality in your web pages. Additionally, there are alternative approaches available that can provide more flexibility and customization depending on your requirements.
