WangleEditor3提交数据(servlet-jsp)

用servlet提交 WangEditor3编辑的内容,找了很多资料没发现,大多用的框架,今天终于解决了,记录一下。

WangEditor3不支持放在textarea中,servlet是无法直接获取到编辑器中的内容的,有一下两种方法:

方法一:如果想用form表单提交需要加个textarea,此时的textarea应该隐藏起来,用js获取WangEditor3编辑的内容,再赋值给textarea,再form提交,隐藏textarea如下:

<textarea name="newscontent" id="content" style="width:100%; height:200px;display:none" ></textarea>

方法二:可以用ajax通过用js取出表单和富文本中的内容,通过json格式传输,在后台获取就可以了。

注明:以下演示以方法二为例,方法一在代码中注释掉了。

效果如下:
