一直想给评论加上简易的编辑器，最近正好有心情折腾一下，研究了一下，现在把实现的方法和大家分享（本文参考了<a class="no-external-link" href="http://imluren.com/2011/01/simple-editor-tools.html" target="_blank">《为评论框添加简单文字编辑器》</a>这篇文章的绝大部分代码，并修改了一些错误，增加了点功能）。

首先在head或者footer加入下面jQuery代码：
```js
/* Comment Editor */
$(function() {
 function addEditor(a, b, c) {
 if (document.selection) {
 a.focus();
 sel = document.selection.createRange();
 c ? sel.text = b + sel.text + c: sel.text = b;
 a.focus()
 } else if (a.selectionStart || a.selectionStart == '0') {
 var d = a.selectionStart;
 var e = a.selectionEnd;
 var f = e;
 c ? a.value = a.value.substring(0, d) + b + a.value.substring(d, e) + c + a.value.substring(e, a.value.length) : a.value = a.value.substring(0, d) + b + a.value.substring(e, a.value.length);
 c ? f += b.length + c.length: f += b.length - e + d;
 if (d == e && c) f -= c.length;
 a.focus();
 a.selectionStart = f;
 a.selectionEnd = f
 } else {
 a.value += b + c;
 a.focus()
 }
 }
 var g = document.getElementById('comment') || 0;
 var h = {
 strong: function() {
 addEditor(g, '', '')
 },
 em: function() {
 addEditor(g, '', '')
 },
 del: function() {
 addEditor(g, '<del>', '</del>')
 },
 underline: function() {
 addEditor(g, '', '')
 },
 quote: function() {
 addEditor(g, '
<blockquote>', '</blockquote>
')
 },
 ahref: function() {
 var a = prompt('请输入链接地址', 'http://');
			var b = prompt('请输入链接描述','');
 if (a) {
 addEditor(g, '<a target="_blank" href="' + a + '"rel="external">' + b + '</a>','')
 }
 },
		img: function() {
		 var a = prompt('请输入图片地址', 'http://');
			if (a) {
 addEditor(g, '<img src="data:image/png;base64,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" data-original="' + a + '" alt="" />','')
 }
 },
 code: function() {
 addEditor(g, '<code>', '</code>')
 }
 };
 window['SIMPALED'] = {};
 window['SIMPALED']['Editor'] = h
});
```

**HTML代码：**
```html
<div id="editor_tools">
 <a href="javascript:SIMPALED.Editor.strong()">粗体</a>
 <a href="javascript:SIMPALED.Editor.em()">斜体</a>
 <a href="javascript:SIMPALED.Editor.del()">删除线</a>
 <a href="javascript:SIMPALED.Editor.underline()">下划线</a>
 <a href="javascript:SIMPALED.Editor.ahref()">链接</a>
 <a href="javascript:SIMPALED.Editor.code()">插代码</a>
 <a href="javascript:SIMPALED.Editor.quote()">引用</a>
 <a href="javascript:SIMPALED.Editor.img()">插图</a>
</div>
```

PS:如果主题使用了wordpress3.0以上提供的数组描述来写的，应根据具体情况适当修改。

最后将下列样式加入样式表：

```css
/* editor_tools */
.editor_tools{margin:0;padding:0;width:360px;height:20px;border-left:1px solid #ddd;}
.editor_tools a{float:left;color:#999;height:20px;line-height:20px;padding:0 5px;font-weight:bold;background:#fafafa;border-top:1px solid .ddd;border-right:1px solid #ddd;}
.editor_tools a:hover{background:#fff;}
```

好了，这样一个简洁但很好用的评论编辑器就加入成功了，赶快试试吧！

不知道该把前面两个方框中的代码加到哪个文件中。head.php或者footer.php？加入后都直接显示在页面上了，HTML那框内的就更不知道该放入哪个文件了。咳，是我自己太差。。。

[...] 　　编辑器去掉了js几十k的QuickTags，换成非插件给wordpress加上评论编辑器，原作者不知是谁（zww？）。 [...]

能加个清除功能就更好了
