我有一个很好的可编辑文本区域与wysihat和contentEditable.我真的需要一种拦截粘贴事件的方法来阻止它们,或者在允许插入之前处理它们的DOM.人们可以将整个网页粘贴到可编辑区域,这有点疯狂.
这可能吗？
来吧,来到我家门口.HTML5大师,火!
我正在使用以下gem作为编辑器.
gem "wysihat-engine", "~> 0.1.13"
当我运行'rails generate wysihat'时,它会生成所有图像文件,但无法生成迁移并产生以下错误

谢谢你的帮助!
我在我的jsp上使用了wysihat引擎.它运作良好,但是当我试图添加是假设从上动态创建的iFrame阅读并把它隐藏预览DIV中值的预览功能,它无法读取iframe的HTML包含.为此做任何解决方法？谢谢!在这个例子中,我想使用jquery返回正文中的值
以下iFrame不是写在我的jsp中,而是通过WYSihat.js文件附加到div:
<iframe id="iframeId" class="abc">
<html>
<head></head>
<body>
<br>
some text here
</br>
</body>
</html>
</iframe>
如何"这里的一些文字"返回并把它传递给下面的函数:提示,此iframe已经飞由WYSiHat.js文件创建的,因为它不是硬在我的jsp页面写
function preview() {
alert("hi"+$('iframe.editor').contents().find('body').text());
}
