Discuz html转bbcode(html2bbcode),bbcode转html(bbcode2html) (js,php)

在进行Discuz二次开发的时候,有时我们需要将编辑器单独使用,由于Discuz发布内容采用了自己独有的bbcode转换方式,为了兼容我们也需要做相应转换。

自己转换不知道规则,只有通过查找源码找到具体的转换函数。

js版本:

引入static/js/bbcode.js

html2bbcode("html内容")//html转bbcode
bbcode2html("bbcode内容")//bbcode转html

 php版本:

//html转bbcode
require_once libfile('function/editor');
echo html2bbcode($html_str);

//bbcode转html
require_once libfile('function/discuzcode'); 
echo discuzcode($bbcode_str, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0);

如下是网友提供的一个完整使用编辑器的例子

<script type="text/javascript" src="{$_G['setting']['jspath']}forum_post.js?{VERHASH}"></script>
<script src="static/js/bbcode.js?{VERHASH}" type="text/javascript"></script>
<script type="text/JavaScript">
    var fid = {$_G['fid']};//插件所在版块ID
</script>

<!--{subtemplate home/editor_image_menu}-->
<textarea class="userData" name="content" id="uchome-ttHtmlEditor" style="height: 100%; width: 100%; display: none; border: 0px"></textarea>
<iframe src='home.php?mod=editor&charset={CHARSET}&allowhtml=1&isportal=0' name='uchome-ifrHtmlEditor' id='uchome-ifrHtmlEditor'  scrolling='no' style='width:85%;height:400px;border:1px solid #C5C5C5;position:relative;' border=0 frameborder=0 ></iframe>
</br>
<input type="hidden" name="formhash" id="formhash" value="{FORMHASH}" />
<input type="hidden" name="posttime" id="posttime" value="{$posttime}" />
<input type="hidden" name="wysiwyg" id="e_mode" value="1" />
<input type="hidden" name="special" value="127" />
<input type="hidden" name="specialextra" value="plugin_test" />
<input type="hidden" id="message" name="message" value="" />
<input id='submit_editsubmit' class='btn' type='button' value='提交'  name='editsubmit' onClick='validate(this);'>
</form>

<script type="text/javascript" src="static/image/editor/editor_base.js?{VERHASH}"></script>
<script type="text/javascript" src="static/image/editor/editor_function.js?{VERHASH}"></script>

<script type="text/javascript">
var textobj = $('uchome-ttHtmlEditor');
var wysiwyg = (BROWSER.ie || BROWSER.firefox || (BROWSER.opera >= 9)) && parseInt('1') == 1 ? 1 : 0;
var allowswitcheditor = parseInt('1');
var allowhtml = parseInt('0');
var allowsmilies = parseInt('1');
var allowbbcode = parseInt('1');
var allowimgcode = parseInt('1');
var simplodemode = parseInt('0');
var fontoptions = new Array("宋体", "新宋体", "黑体", "微软雅黑", "Arial", "Verdana", "Mingliu", "Helvetica", "Trebuchet MS", "Tahoma", "Impact", "Times New Roman", "仿宋,仿宋_GB2312", "楷体,楷体_GB2312");
var smcols = 8;
var custombbcodes = new Array();
</script>

<script type="text/JavaScript">

function validate(obj) {
var mcpp = window.frames['uchome-ifrHtmlEditor']; var mcpobj = mcpp.window.frames['HtmlEditor']; edit_save(); jQuery("#message").val(html2bbcode(mcpobj.document.body.innerHTML));//将编辑器内容转bbcode window.onbeforeunload = null; obj.form.submit(); return false; }</script>

在编辑时直接读取数据库中内容无法按html展示,且再次保存时会遇到“您的提交带有不合法参数,谢谢合作”,我们需要预先将存到数据库的bbcode转成html加载到编辑器

window.onload = function(){
    var mcpp = window.frames['uchome-ifrHtmlEditor'];
    var mcpobj = mcpp.window.frames['HtmlEditor'];
    mcpobj.document.body.innerHTML = bbcode2html("{$thread['message']}");//加载完成时将bbcode内容转换成正常的html代码并赋值
}
