    KindEditor的使用(文件上传和文件管理)

    4、基本使用

    <textarea name="content" id="content"></textarea>
     
    <script src="/static/jquery-1.12.4.js"></script>
    <script src="/static/plugins/kind-editor/kindeditor-all.js"></script>
    <script>
        $(function () {
            initKindEditor();
        });
     
        function initKindEditor() {
            var kind = KindEditor.create('#content', {
                 '100%',       // 文本框宽度(可以百分比或像素)
                height: '300px',     // 文本框高度(只能像素)
                minWidth: 200,       // 最小宽度(数字)
                minHeight: 400      // 最小高度(数字)
            });
        }
    </script>

    5、详细参数

         http://kindeditor.net/docs/option.html

    主要的参数(itmes,resizeType,useContextmenu,uploadJson,fileManagerJson,extraFileUploadParams,filePostName)

    6,上传文件示例

    html

    <!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
