你要的是所见即所得HTML编辑器，简单来说需要几个基本步骤：
1，需要一个可以编辑同时又可显效果的编辑框。textarea不行，它只能用来输入纯文本，不能显示颜色、斜体之类的文字样式，就像记事本。
你可以使用iframe来实现，修改iframe的designMode属性使其可以被编辑。
这样你就可以在这个iframe区域里写字了。
2，选中要添加样式的文字。通常我们用WORD编辑一段文字的样式时，一般是先打字，再编辑样式。所以你需要一个选中要处理文本的方法。JS的selection.createRange()可以选中文本，返回一个对象，你可以通过访问该对象的text属性得到被选中的文本。
3，改变被选中文本的样式。selection.createRange()选中文本，返回一个对象，该对象有一个方法execCommand()，可以用来改变被选中文本的样式。
execCommand()的常用用法：
字体--宋体、黑体、楷体等
execCommand("fontname","",字体)
字号--字号大小
execCommand("fontsize","",字号)
加重
execCommand("Bold")
斜体
execCommand("Italic")
下划线
execCommand("Underline")
删除线
execCommand("StrikeThrough")
居左
execCommand("JustifyLeft")
居右
execCommand("JustifyRight")
居中
execCommand("JustifyCenter")
剪切
execCommand("Cut")
拷贝
execCommand("Copy")
粘贴
execCommand("Paste")
取消操作--IE5.0以后可以无限取消
execCommand("Undo")
重复操作
execCommand("Redo")
把上面的每个用法用按钮来实现，你就已经完成了一个简单的可视文本编辑器。
