想写一个富文本编辑器，但是在执行execCommand的时候报错，请帮忙看看
代码如下<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Index</title>
<script type="text/javascript">
var editor;
function InitEditor() {
editor = document.getElementById("editor");
editor = editor.contentWindow;
editor.document.designMode = "on";
setTimeout(function() {
editor.focus();
}, 10);
} function SetBold() {
document.execCommand("Blod",false,null);
} function SetItalic() {
} function SetUnderline() {
}
</script>
</head>
<body onload="InitEditor();">
<div><span><img onclick="SetBold();" src="/Images/EditorIcon/Bold.jpg" /></span>
<span><img src="/Images/EditorIcon/Italic.jpg" onclick="SetItalic();" /></span>
<span><img onclick="SetUnderline();" src="/Images/EditorIcon/Underline.jpg" /></span></div>
<iframe id="editor" src="about:blank" width="200" height="200"></iframe>
</body>
</html>再次感谢。
