CKEditor setData使编辑器BLANK Firefox 9

Question

我想在CKEditor中编辑格式化的HTML，但问题是如果我动态设置值，那么它只能在“SOURCE”模式下查看，它显示为空白！

我用过

<textarea name="text2" id="text2"><?php echo $text; ?></textarea>
var str=document.getElementById('text2').value;
CKEDITOR.instances.text.setData(str);

和

CKEDITOR.instances.text.setData('<?php echo htmlentities($HTMLcode, ENT_QUOTES); ?>');

我尝试过的示例数据

<h3 style="color:blue;">

但是如何在CKEditor中设置包含上述任何字符串的数据？
