Question

我的html文件中有textarea，我需要将textarea中的数据发送到数据库。但是，textarea在没有enter空格的情况下发送数据。所以像这样的数据：

Shortly after reading a few books on web design, I was hooked. I wanted to know everything and anything about it. I was designing websites any chance I could. 

I spent almost all of my savings buying more books on different programming languages and other nerdy computer gear.

在数据库中会是这样的。

所以我决定将textarea更改为ckeditor以将数据发送为html。但问题是，我jQuery上有textarea方法，现在它无效。

HTML：

<td>
<textarea maxlength="5000" id="blah" cols="100" rows="20" name="essay_content" class="ckeditor" onkeyup="words();">
</textarea></td>

jQuery的：

function words(content)
{
    var f = $("#blah").val()
    $('#othman').load('wordcount.php?content='+ encodeURIComponent(f));


}

现在它不适合我，因为文本区域是CkEditor ...有什么建议吗？

Answer 1

这应该可以获得CkEditor textarea的内容：

function words(content)
{
    var f = CKEDITOR.instances.blah.getData();
    $('#othman').load('wordcount.php?content='+ encodeURIComponent(f));
}

但是，我不认为onkeyup会起作用，因为CkEditor会替换textarea。您需要为CkEditor创建一个插件，以捕获编辑器实例中的键向上触发器。

Answer 2

我使用了nlbr，一切正常。

在CkEditor上应用jQuery函数
