commit e2d353475109bfa587a685c006818980572974cb Author: Alexandre Allaire <alexandre.allaire@mail.mcgill.ca> Date: Thu Dec 6 19:03:59 2012 -0500 Add wrapper function to attach DOM events. The current code uses the standard addEventListener which is not supported in IE <= 8. Add a small wrapper function which uses the IE attachEvent method if it is available. --- proxy/options.js | 17 +++++++++++++---- 1 files changed, 13 insertions(+), 4 deletions(-) diff --git a/proxy/options.js b/proxy/options.js index 326043e..f39f358 100644 --- a/proxy/options.js +++ b/proxy/options.js @@ -6,7 +6,16 @@ var COOKIE_NAME = "flashproxy"; /* max-age is not supported in IE. */ var COOKIE_LIFETIME = "Thu, 01 Jan 2020 00:00:00 GMT"; -window.addEventListener("load", function () { +/* This wrapper will attach events correctly in older + versions of IE. */ +function add_event(elem, evt, handler) { + if (elem.attachEvent) + elem.attachEvent("on" + evt, handler); + else + elem.addEventListener(evt, handler); +} + +add_event(window, "load", function () { function cookie_present() { var cookies = document.cookie.split(";"); @@ -46,9 +55,9 @@ window.addEventListener("load", function () { if (navigator.cookieEnabled) { var buttons = document.getElementById("buttons"); - buttons.addEventListener("click", update_setting_text); - document.getElementById("yes").addEventListener("click", set_cookie); - document.getElementById("no").addEventListener("click", del_cookie); + add_event(buttons, "click", update_setting_text); + add_event(document.getElementById("yes"), "click", set_cookie); + add_event(document.getElementById("no"), "click", del_cookie); buttons.style.display = "block"; update_setting_text(); } else {
