你要的是所見即所得HTML編輯器，簡單來說需要幾個基本步驟：
1，需要一個可以編輯同時又可顯效果的編輯框。textarea不行，它只能用來輸入純文本，不能顯示顏色、斜體之類的文字樣式，就像記事本。
你可以使用iframe來實現，修改iframe的designMode屬性使其可以被編輯。
復制代碼 代碼如下:
<iframe id="myEditer" width="100%" height="150px"></iframe>
<script>myEditer.document.designMode = 'on';</script>
這樣你就可以在這個iframe區域裡寫字了。
2，選中要添加樣式的文字。通常我們用WORD編輯一段文字的樣式時，一般是先打字，再編輯樣式。所以你需要一個選中要處理文本的方法。JS的selection.createRange()可以選中文本，返回一個對象，你可以通過訪問該對象的text屬性得到被選中的文本。
復制代碼 代碼如下:
<iframe id="myEditer" width="100%" height="150px"></iframe>
<input type="button" value="加粗" onclick="Bold()">
<script>
myEditer.document.designMode = 'on';
function Bold(){
var sel = myEditer.document.selection.createRange();
alert(sel.text);
}
</script>
3，改變被選中文本的樣式。selection.createRange()選中文本，返回一個對象，該對象有一個方法execCommand()，可以用來改變被選中文本的樣式。
復制代碼 代碼如下:
<iframe id="myEditer" width="100%" height="150px"></iframe>
<input type="button" value="加粗" onclick="Bold()">
<script>
myEditer.document.designMode = 'on';
function Bold(){
var sel = myEditer.document.selection.createRange();
//alert(sel.text);
sel.execCommand("Bold")
}
</script>
execCommand()的常用用法：
字體--宋體、黑體、楷體等
execCommand("fontname","",字體)
字號--字號大小
execCommand("fontsize","",字號)
加重
execCommand("Bold")
斜體
execCommand("Italic")
下劃線
execCommand("Underline")
刪除線
execCommand("StrikeThrough")
居左
execCommand("JustifyLeft")
居右
execCommand("JustifyRight")
居中
execCommand("JustifyCenter")
剪切
execCommand("Cut")
拷貝
execCommand("Copy")
粘貼
execCommand("Paste")
取消操作--IE5.0以後可以無限取消
execCommand("Undo")
重復操作
execCommand("Redo")
把上面的每個用法用按鈕來實現，你就已經完成了一個簡單的可視文本編輯器。
