How to create a dialog with “yes” and “no” options

Question

I am going to make a button to take an action and save the data into a database.

Once the user clicks on the button, I want a JavaScript alert to offer “yes” and “cancel” options. If the user selects “yes”, the data will be inserted into the database, otherwise no action will be taken.

How do I display such a dialog?

Answer 1

You’re probably looking for confirm(), which displays a prompt and returns true or false based on what the user decided:

if (confirm('Are you sure you want to save this thing into the database?')) {    // Save it!    console.log('Thing was saved to the database.');  } else {    // Do nothing!    console.log('Thing was not saved to the database.');  }

Answer 2

var answer = window.confirm("Save data?"); if (answer) {     //some code } else {     //some code } 

Use window.confirm instead of alert. This is the easiest way to achieve that functionality.
