Custom Dialog Box

This script is a replacement for Javascript's native confirm() method.

It lets you add or remove buttons, set the text of the dialog box, and style everything with CSS. Because the CustomDialogBox is chainable, it's quick and clean to use.

Because this is written in native Javascript, it doesn't require any external libraries.

Getting Started

After including the Javascript and basic CSS file in your page, follow these steps.

Set the dialog box like so:

var dialog = new CustomDialogBox();

Then, instantiate it to set up the DOM elements:

dialog.create();

To set the text of the dialog:

dialog.setText('Hello World!');

To show the dialog box, or to hide it:

dialog.show():

dialog.hide();

Adding buttons is simple. Just call the addButton() method for each button you want to add. addButton() takes three arguments - the internal system name for the button (which will also be used as part of the ID, in case you want to individually style it), the label for the button, and a callback function that will be called when the button is clicked.

dialog.addButton('ok', 'OK', function() {
  alert('You clicked OK!');
  dialog.hide();
});

Similarly, you can also remove a button by referring to its internal system name that you set when you created it:

dialog.removeButton('ok');

If you want to center the dialog box in the middle of the viewport, use the following method:

dialog.centerPosition();

Finally, if you want to completely remove the DOM elements but leave the object intact, you can call this method:

dialog.destroy();

Chaining

You can chain any of the above methods if you want. So, the following is perfectly fine:

dialog.create()
    .addButton('ok', 'OK', function() { alert('You hit OK!'); dialog.hide(); })
    .addButton('cancel', 'Cancel', function() { alert('You hit Cancel!'); dialog.hide(); })
    .hide()
;

CSS Styling

The Backdrop

The transparent black backdrop has an ID of customDialogBoxBackgroundContainer. This is the only element that is NOT contained inside of the main container.

The Main Container

The dialog box is contained in a <div> with an ID of customDialogBoxContainer.

Buttons

Buttons contained inside have an ID of customDialogBoxButton-<systemname> where <systemname> is the name you set in the first argument of addButton(). So, for example, you might have a button with an ID of customDialogBoxButton-ok.
