dialog methods

var dialog = HtmlDialog.Dialog({...});

dialog.create(dialogOptions);
dialog.open();
dialog.close();
dialog.destroy();
dialog.getDialog();
dialog.getForm();

.create()

You can pass an optional parameter to the create() method to specify the parent element.

var dialog = HtmlDialog.Dialog({...});
dialog.create({
    appendTo: document.getElementById('my-dialog-container')
});

dialog options parameter

HtmlDialog.Dialog({
    title: 'Dialog Title',
    content: 'Dialog Content',
    buttons: [
        // ...
    ],
    classNames: {
        // ...
    }
})

buttons parameter

{
    title: 'Dialog Title',
    content: 'Dialog Content',
    ...
    buttons: [
        {
            text: 'OK',
            type: 'button',
            focus: true,
            classNames: 'btn btn-primary',
            onclick: function (mouseevent) {
                console.log(mouseevent);
                this.close();
            }
        }
    ]
}

All valid mouse events are supported. See: https://www.w3schools.com/jsref/obj_mouseevent.asp

The callback function will be called with the dialog instance as this and the mouseevent as the first argument.

onclick: function (mouseevent) {
    console.log(mouseevent);
    this.close();
}

It's possible to add multiple callbacks to a button:

{
    text: 'OK',
    onclick: function () {
        console.log('onclick');
    },
    oncontextmenu: function () {
        console.log('contextmenu');
    }
}

classNames parameter

This option allows you to add custom css classnames to the dialog.

HtmlDialog.Dialog({
    title: 'Example',
    content: 'Hello World!',
    buttons: [
        // ...
    ],
    classNames: {
        dialog: 'dialog-class',
        title: 'title-class',
        content: 'content-class',
        buttons: 'buttons-class',
    }
});

The above code will result in the following html:

<dialog class="dialog-class">
    <form>
        <div class="title-class">Example</div>
        <div class="content-class">Hello World!</div>
        <div class="buttons-class">
            <button>OK</button>
            <button>Cancel</button>
        </div>
    </form>
</dialog>

example styles with backdrop:

.dialog-class {
    border: 1px solid red;
    padding: 0;
}

.dialog-class::backdrop {
    background-color: aqua;
}

                    console.log(value);
                    this.close();
