变量是一个可以变的数,可以看作是一个数据的容器。变量有2个操作,一个是读,一个是写。Axure的全局变量是指任何时候都可以对这个变量进行读写操作。

 

点击工具栏Project下的Global Variables,这里可以设置全局变量。

 

可以看到,默认已经有一个全局变量。还可以新建变量,变量是可以有默认值的。

 

现在自定义一个全局变量。

 

向页面中拖入一个Rectangle,设置Rectangle的样式,在Shape Name中设置为rack。

 

再拖入一个Rectangle,设置成圆形并填充上颜色,作为按钮使用。

 

给圆形的Rectangle设置用例如下:

 

预览,点击蓝色按钮出现文字,如下:

 

以上是对全局变量值的读取,如何更改全局变量呢?

 

把刚才的页面内容复制到另外一个页面,重写设置OnClick事件如下:

 

预览,点击蓝色按钮,这次显示的内容是我们设置的内容。

 

以上是重新设置并显示变量的值,是否可以通过函数改变变量的值呢?

 

把刚才的页面内容复制到另外一个页面,重写按钮的OnClick事件如下:

 

以上,设置变量的值是通过函数计算而得。

 

预览,点击蓝色按钮,显示如下:

 

总结:全局变量可以随时读取,并可以通过直接赋值或函数赋值来改变全局变量的值。
