variable's attribute

Data binding is performed using braces ( for example, the TextArea element's text attribute is bound to the ActionScript message instance variable).

数据绑定通过大括号执行（例如，将TextArea元素的text属性绑定到ActionScript message实例变量）。

The variable's name is obtained from the JSP context because it is passed to the tag file as a JSP attribute.

变量名称可以通过JSP上下文获取，因为它作为JSP属性传递到标记文件。

The other way is to read it from the value binding that corresponds to the temporary loop variable, which is defined in the component tag's var attribute.

另一种方法是从对应于临时循环变量的值绑定中读取该数据，该变量定义在组件标记的var属性中。
