能否用Orbeon表单实现无需Flash的警笛声含义调查功能？

Hey there! Great news—Orbeon Forms absolutely lets you add audio playback to your civil defense survey, and you won't need Flash Player at all, which solves your LimeSurvey headache right away. You can build exactly the workflow you described: click buttons to play different alert sounds, then use dropdown menus for respondents to select their meaning.

How to Implement This in Orbeon #

Orbeon works seamlessly with HTML5's native <audio> element, which is supported by all modern browsers. Here's a step-by-step breakdown:

1. Upload your audio files
   First, upload your civil defense alert sound files (MP3, WAV, etc.) to Orbeon's resource library. This keeps your files hosted securely alongside your form.

2. Add audio elements and playback buttons
   Use Orbeon's "Custom HTML" component to embed hidden <audio> tags for each sound, plus buttons to trigger playback. For example:

   <!-- Hidden audio element for a warning alert -->
   <audio id="warning-alert" src="/orbeon/resources/audio/warning.mp3" preload="auto"></audio>
   <!-- Button to play the sound -->
   <button onclick="document.getElementById('warning-alert').play()">播放预警警报声</button>
   

   Repeat this for each distinct alert sound you need to include.

3. Pair with dropdown menus
   Add standard Orbeon dropdown controls next to each playback button. Configure the dropdown options to match the possible meanings of the corresponding sound (e.g., "危险临近预警", "危险解除信号"). You can even add validation rules to ensure respondents select an option after playing the sound, if needed.

4. Test across browsers
   Since we're using native HTML5 audio, this will work on Chrome, Firefox, Safari, and Edge without any extra plugins—no Flash required.

Why This Works Better Than LimeSurvey for Your Use Case #

Unlike LimeSurvey's reliance on Flash for audio, Orbeon leverages modern web standards. This means better compatibility with current browsers, no security risks associated with outdated plugins, and a smoother experience for your survey respondents.

Quick reminder of your core requirement (from your reference):
民防警报器用于向民众发出危险临近的紧急预警，有时也用于指示危险已解除……通过不同音调或声音开关模式，可传达不同警报状态。

This setup perfectly aligns with that—you can present each distinct alert sound, then capture whether respondents understand its meaning via the dropdown selections.
