1. 在编辑页面引入js
<script type="text/javascript" charset="utf-8" src="${basePath }/js/plugin/kindeditor-4.1.7/kindeditor-min.js"></script> <script type="text/javascript" charset="utf-8" src="${basePath }/js/plugin/kindeditor-4.1.7/lang/zh_CN.js"></script>
2.textarea绑定
<textarea name="content" class="common-textarea" id="content" style="width:100%; height:580px;visibility:hidden;"></textarea>
3.初始化插件
1 var editor = KindEditor.create('textarea[name="content"]', {
2 uploadJson : basePath + '/kindeditor/fileUpload',
3 fileManagerJson : basePath + '/kindeditor/fileManager',
4 allowFileManager : true,
5 items : ['source', '|', 'undo', 'redo', '|', 'preview', 'template', 'cut', 'copy', 'paste',
6 'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright',
7 'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript',
8 'superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/',
9 'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold',
10 'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image','multiimage',
11 'flash', 'media', 'insertfile', 'table', 'hr', 'emoticons', 'baidumap', 'pagebreak',
12 'anchor', 'link', 'unlink']
13 });
