每當頁面加載時，如何使插件運行函數

Question

我正在開發Firefox插件，我希望它在每個表單字段上添加一個事件偵聽器。 我將如何實施呢？

Answer 1

// 'extension is loaded', you probably have this
window.addEventListener("load", function() {
    // run your_function() when page is loaded and DOM is ready
    gBrowser.addEventListener("DOMContentLoaded", your_function, true);
}, false);
