使用javascript获取ckeditor textarea的textarea值 [英] Getting the textarea value of a ckeditor textarea with javascript

问题描述

对于JS，我是一个学习者，虽然我花了好几个小时阅读通过教程，这已经帮助了很多，但我仍然有问题，弄清楚我究竟是如何找到一个用户键入a ckeditor textarea。

I'm a learner as far as JS goes and although I've spent a good few hours reading through tutorials which has helped lots but I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

我想要做的是，当有人输入textarea时，无论它们的类型出现在不同部分的div页面。

What I'm trying to do is have it so that when someone types into the textarea, whatever they type appears in a div in a different part of the page.

我有一个简单的文本输入，但是因为文本区域是一个ckEditor类似的代码不工作。

I've got a simple text input doing that just fine but because the text area is a ckEditor the similar code doesn't work.

我知道答案在这里：ckEditor API textarea值<但是我不知道我想要做什么。

I know the answer is here: ckEditor API textarea value but I don't know enough to figure out what I'm meant to do. I don't suppose anyone fancies helping me out?

我工作的代码是：

$('#CampaignTitle').bind("propertychange input", function() {
  $('#titleBar').text(this.value);
});

和

<label for="CampaignTitle">Title</label>
<input name="data[Campaign][title]" type="text" id="CampaignTitle" />

和

<div id="titleBar" style="max-width:960px; max-height:76px;"></div>

推荐答案

有问题确切地说明我如何找到一个
用户正在输入ckeditor文本区。

I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

相当容易。假设你的编辑器被命名为editor1，这将给你一个警告与它的内容：

Ok, this is fairly easy. Assuming your editor is named "editor1", this will give you an alert with your its contents:

alert(CKEDITOR.instances.editor1.getData());

更难的部分是检测用户键入的时间。从我可以告诉，实际上没有支持这样做（和我不是太深刻的文档btw）。请参阅这篇文章：

The harder part is detecting when the user types. From what I can tell, there isn't actually support to do that (and I'm not too impressed with the documentation btw). See this article: http://alfonsoml.blogspot.com/2011/03/onchange-event-for-ckeditor.html

相反，我建议设置一个定时器，将持续更新您的第二个div of textarea：

Instead, I would suggest setting a timer that is going to continuously update your second div with the value of the textarea:

timer = setInterval(updateDiv,100);
function updateDiv(){
    var editorText = CKEDITOR.instances.editor1.getData();
    $('#trackingDiv').html(editorText);
}

这似乎工作很好。这里是整个事情为了清楚：

This seems to work just fine. Here's the entire thing for clarity:

<textarea id="editor1" name="editor1">This is sample text</textarea>

<div id="trackingDiv" ></div>

<script type="text/javascript">
    CKEDITOR.replace( 'editor1' );

    timer = setInterval(updateDiv,100);
    function updateDiv(){
        var editorText = CKEDITOR.instances.editor1.getData();
        $('#trackingDiv').html(editorText);
    }
</script>
