如何讓 Moodle 1.9.5 在 IE11、Chrome 等兩個瀏覽器中仍能看到 HTML Editor 的解決方法

IE Version 11:

主選單 --> 工具 --> 相容性檢視設定 --> "將 Moodle 1.9.5 所在的網域加入 [相容性檢視] 的網站"。

Chrome:

此方法引用自：http://lewiscarr.co.uk/2010/08/enable-the-moodle-wysiwyg-editor-on-chrome-and-safari/

1. 修改 lib/moodlelib.php，將

function can_use_html_editor() {
     global $USER, $CFG;
 
     if (!empty($USER->htmleditor) and !empty($CFG->htmleditor)) {
         if (check_browser_version('MSIE', 5.5)) {
             return 'MSIE';
         } else if (check_browser_version('Gecko', 20030516)) {
             return 'Gecko';
         }
     }
     return false;
 }

修改為：

function can_use_html_editor() {
     global $USER, $CFG;
 
     if (!empty($USER->htmleditor) and !empty($CFG->htmleditor)) {
         if (check_browser_version('MSIE', 5.5)) {
             return 'MSIE';
         } else if (check_browser_version('Gecko', 20030516)) {
             return 'Gecko';
         } else { 
            return 1; //Pall's Safari/Chrome editor hack
         } 
     }
     return false;
 }

2. 修改 lib/editor/htmlarea/htmlarea.php，將
   

   HTMLArea.checkSupportedBrowser = function() {
        if (HTMLArea.is_gecko) {
            if (navigator.productSub < 20021201) {
                alert("You need at least Mozilla-1.3 Alpha.\n" +
                      "Sorry, your Gecko is not supported.");
                return false;
            }
            if (navigator.productSub < 20030210) {
                alert("Mozilla < 1.3 Beta is not supported!\n" +
                      "I'll try, though, but it might not work.");
            }
        }
        if(HTMLArea.is_safari) {
            return false;
        }
        return HTMLArea.is_gecko || HTMLArea.is_ie;
    };

   修改為：
   

   HTMLArea.checkSupportedBrowser = function() { 
       if (HTMLArea.is_gecko) {
           if (navigator.productSub < 20021201) {
               alert("You need at least Mozilla-1.3 Alpha.\n" +
                     "Sorry, your Gecko is not supported.");
               return false;
           }
           if (navigator.productSub < 20030210) {
               //alert("Mozilla < 1.3 Beta is not supported!\n" +
               //      "I'll try, though, but it might not work.");
               return 'HTMLArea.is_gecko';
           }
       }
       if(HTMLArea.is_safari) {
           //return false;
           return 'HTMLArea.is_gecko';
       }
       return HTMLArea.is_gecko || HTMLArea.is_ie;
   };
