使用JS代码定制交互行为

功能概述

文中以一个这样的示例展示具体操作方法:

在仪表板中单击图片,3D场景的中的部分房子消失,再次点击图片,房子出现。这就是使用JS代码定制的一种交互行为。

3D-JS脚本

操作介绍

具体操作步骤如下:

1. 3D场景中添加JS脚本

单击场景设定,在属性设置中找到数据交互,打开以后可以看到自定义代码,单击右侧加号。

image

填写脚本名称,然后选择一个执行脚本的时机。这里支持场景加载完成数据图层数据改变手动触发三种执行时机。

例如我们选择了手动触发,然后在右侧编写脚本,控制四个小房子的隐藏和出现。

最后单击确定

选择不同的执行时机,支持的参数不同。

手动触发场景加载完成支持的参数如下。

参数类型:

type=info

提示

通过 sceneData 对象的以下两个方法可以显示或隐藏数据图层。

  • enableDataLayer

  • disableDataLayer


用法示例:

sceneData.disableDataLayer("模型数据标注")

数据图层数据改变支持的参数如下。

参数类型:

2. 在仪表板中使用

示例中是一个手动触发的JS脚本,所以这里我们添加一个图片,并为其设置左键选项为命令

添加一条命令,并设置命令。
