前幾天,覺得blog的插入代碼不夠好用。於是,將sina的html編輯器更換為了tinyMCE。並且開發了一個簡單的插入代碼的功能。 。 。下面就是我開發的過程。
首先,我的tinyMCE版本是Version: 3.2.7 (2009-09-22) 。
tinyMCE插入代碼,需要調用tinyMCE的tinyMCE.execCommand('mceInsertContent',false,value); 方法。其中參數無需改變,value 就是你要插入的內容,
比如我寫了一個函數,
複製代碼代碼如下:
function InsertHTML(value)
{
tinyMCE.execCommand('mceInsertContent',false,value);
}
後面,針對該例子,提供下載。在例子中。一共涉及到三個文件。
tinyMCE.html insertcode.php save.php 這三個文件。
tinyMCE.html 是tinyMCE文本框頁面。
主要代碼如下:
複製代碼代碼如下:
<script type=text/javascript src=http://www.vevb.com/tinymce/tiny_mce.js></script>
<script type=text/javascript>
tinyMCE.init({
// General options
convert_urls : false,
mode : exact,
elements : Article_Content,
//mode : textareas,
theme : advanced,
plugins : safari,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template,wordcount,
// Theme options
theme_advanced_buttons1 : save,newdocument,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,styleselect,formatselect,fontselect,fontsizeselect,
theme_advanced_buttons2 : cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,preview,|,forecolor,backcolor,
theme_advanced_buttons3 : tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,emotions,iespell,media,advhr,|,print,|,ltr,rtl,|,fullscreen,
theme_advanced_buttons4 : insertlayer,moveforward,movebackward,absolute,|,styleprops,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,template,pagebreak,
theme_advanced_toolbar_location : top,
theme_advanced_toolbar_align : left,
theme_advanced_statusbar_location : bottom,
theme_advanced_resizing : true,
// Example content CSS (should be your site CSS)
content_css : css/content.css,
// Drop lists for link/image/media/template dialogs
template_external_list_url : lists/template_list.js,
external_link_list_url : lists/link_list.js,
external_image_list_url : lists/image_list.js,
media_external_list_url : lists/media_list.js,
// Replace values for the template plugin
template_replace_values : {
username : Some User,
staffid : 991234
}
});
</script>
<script type=text/javascript>
function InsertHTML(value)
{
tinyMCE.execCommand('mceInsertContent',false,value);
}
</script>
其中js代碼是初始化tinyMCE。下載的例子中,並未包含tinyMCE,你需要自己下載。然後更改js代碼的src 即可。
複製代碼代碼如下:
<input name=button type=button onclick=window.open('insertcode.php','插入代碼','height=500, width=600, top=300, left=300, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=no, status=no') value=點擊這裡插入代碼/>
上面這段代碼,是用來打開insertcode.php文件的。
接下來,我們來看下insertcode。 php 這個文件的代碼。
首先是js 代碼
複製代碼代碼如下:
<script language=javascript src=http://www.gosoa.com.cn/js/jquery.js></script>
<script language=javascript>
function insertcode()
{
var value = $('#postcontent').html();
var codetype = $('#codetype').val();
// window.opener.InsertHTML('<textarea rows=3 cols=50 name=code class='+codetype+'>'+value+'</textarea>');
window.opener.InsertHTML('<pre name=code class='+codetype+'>'+value+'</pre>');
window.close();
}
</script>
其次是PHP 和html 代碼
複製代碼代碼如下:
<?php
error_reporting(0);
$content = $_POST['content'];
if(!empty($content))
{
$codetype = $_POST['codetype'];
echo '<div id=postcontent>';
$content = htmlspecialchars($content);
echo $content;
echo '</div>
<input type=hidden name=codetype id=codetype value='.$codetype.' />
<input type=button name=Submit value=提交onclick=insertcode() style=border:1px solid #000; line-height:18px; width:60px;/>';
}else
{
?>
<div style=margin:0 auto>
<form id=form1 name=form1 method=post action=insertcode.php>
<label>選擇要插入的代碼類型
<select name=codetype id=codetype>
<option value='php'>php</option>
<option value='js'>js</option>
<option value='html'>html</option>
<option value='c'>c</option>
<option value='asp'>asp</option>
<option value='xml'>xml</option>
<option value='java'>java</option>
<option value='java'>java</option>
<option value='CSharp'>C#</option>
<option value='sql'>SQL</option>
</select>
</label>
<label>
<textarea name=content id=content cols=30 rows=20 style=width:600px; height:200px; border:1px dashed #333></textarea>
</label>
<p>
<label style=padding-left:50px;>
<input type=Submit name=Submit value=提交style=border:1px solid #000; line-height:18px; width:60px;/>
</label>
</p>
<p> </p>
</form>
</div>
<?php
}
?>
在insertcode.php中,insertcode() 函數用來調用tinyMCE.html頁面的insertHTMl()函數,並將代碼插入到tinyMCE.html 頁面中。
代碼中,我們為什麼要'+value+' 呢?
因為我們在顯示頁面,將會採用SyntaxHighlighter 插件來高亮顯示代碼。
還有一點要說明,在這裡,$content = htmlspecialchars($content); 我們對於代碼本身,進行了htmlspecialchars 轉義操作。這樣,插入數據庫的代碼則會是安全的。
OK,我們再來看save.php,該頁面用來顯示提交的內容。
主要代碼如下:
複製代碼代碼如下:
<?
$Article_Content = $_POST['Article_Content'];
function transcode($str)
{
if(empty($str))
{
return false;
}
$str = str_replace('','',$str);
$str = str_replace('','',$str);
$str = str_ireplace('<BR>',n,$str);
$str = str_ireplace('<pre','<pre name=code ',$str);
return $str;
}
echo transcode($Article_Content);
?>
<script class=javascript src=/tinymce/lightcode/Scripts/shCore.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushCSharp.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushPhp.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushJScript.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushJava.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushVb.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushSql.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushXml.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushDelphi.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushPython.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushRuby.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushCss.js></script>
<script class=javascript src=/tinymce/lightcode/Scripts/shBrushCpp.js></script>
<script class=javascript>
dp.SyntaxHighlighter.HighlightAll('code');
</script>
OK,完了。
