修改新闻
数据
您正试图通过文本区域的名称来选择文本区域，但是CKEDITOR.replace（'modificatesto'）正在查找ID
试一试

CKEDITOR.replace（'modificatesto'）；
对于有相同问题的人：
我通过以下方式解决了问题：在javascript上添加新行：
document.getElementById("newsdamodificare").action=CKEDITOR.replace('modificatesto');

在这两行之间：
document.getElementById("newsdamodificare").innerHTML=xmlhttp.responseText;
NEW LINE TO INSERT HERE
}

并从php中删除以下行：
<script>
    CKEDITOR.replace('modificatesto');
</script>


CKEDITOR.replace（'modificatesto'）；

希望这有帮助 不幸的是，这不是问题所在。。。我试过了，但没用。。。另外，另一个javascript不工作。。。我的页面中有其他CKEDITOR，它们使用名称而不使用ID。
document.getElementById("newsdamodificare").innerHTML=xmlhttp.responseText;
NEW LINE TO INSERT HERE
}

<script>
    CKEDITOR.replace('modificatesto');
</script>
