 # 创建控件的Json文件格式说明
-Bricks在服务器端使用Json文件格式存储控件描述文件，前端获得json文件后转化为json对象，并用词json对象调用widgetBuild函数创建Bricks控件。
+Bricks在服务器端使用Json文件格式存储控件描述文件，前端获得json文件后转化为json对象，并用此json对象调用widgetBuild函数创建Bricks控件。
 
 控件描述json文件必须含有“widgettype” 和”options“两个属性。“subwidgets”属性用来定义此控件包含的子控件。“binds”用于定义此控件或其子控件的事件处理
 
 
 ## widgettype说明
 widgettype是一个字符串属性。其值为Bricks中的所有控件类型或"urlwidget"
-可用的控件类型可以在[控件类型清单](widgettypes.md)中查找
+可用的控件类型可以在[控件类型清单](widgets.md)中查找
 
 ## options
 对象类型，每个控件有特定的options属性，清参看每个控件的说明
