Customizing

windog.js

// custom dialog interface
let SELF = {
    prompt,
    // ...
};

// default option, template ID, and resolve handler/callback
let dialogOptions = {
    prompt: {
        defaultValue: null,
        templateId: 'tmp-dialog-prompt',
        onResolve: (resolve, dialogEl) => {
          // provide custom callback. always resolve to show the next dialog in queue if you await the function.
          // resolve();
          handlePromptDialog(resolve, dialogEl)
        },
    },
    // ...
};

// custom dialog function
// showDialogAsync(defaultOption, userOption)
async function prompt(message='', defaultValue='') {
    return await showDialogAsync(dialogOptions.prompt, {
        message,
        defaultValue,
