 9  
10     function initKindEditor() {
11         var kind = KindEditor.create('#content', {
12             width: '100%',       // 文本框宽度(可以百分比或像素)
13             height: '300px',     // 文本框高度(只能像素)
14             minWidth: 200,       // 最小宽度（数字）
15             minHeight: 400      // 最小高度（数字）
16         });
17     }
