There are also clever ways of styling the label to look like a checkbox and hiding the actual checkbox so you can use your own graphic, font icon or CSS creation: , but actually toggling the checkbox in the background.

We know the checkbox is changing because that's what drives the CSS effect: The HTML for this example is the same as above. I'm not much of a developer, but stubble on your website searching for exactly what you posted here.

Did you find any of these examples useful or have any questions? However, I noticed that your script is throwing errors and thought maybe i'd check with you to see if you might know why. I'm getting : Uncaught Syntax Error: Unexpected token ...

and then about 4 of these: Uncaught Type Error: Cannot read property 'add Event Listener' of null(…) Anyways, just thought I'd see if you knew why.

The advantage for the user is that it's obvious whick element is causing the problem and there's no alert window that needs to be clicked away.Using vanilla Java Script we can prevent form submission as follows: All this does is confirm before submitting the form that the checkbox is checked.If not, an alert is displayed and focus is moved to the checkbox.We know that the checkbox is unchecked by default so we need to tell the browser what message to display.The event handler on the checkbox then toggles the error message.
