Quick Reference
The Window confirm() method displays a dialog box with a message, an OK button, and Cancel button. The confirm() method returns “true” if the user clicked “OK”, and “false” if the user clicked “Cancel”.
<button onclick="my_function()">Choose</button>// function for button
function my_function() {
confirm('Press a button');
}Output
(an alert will popup with an okay and cancel button)
(when clicked it will return true or false)Syntax
confirm(message)JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
