renderjs 不同平台运行效果不一致

使用renderjs向外传递了一个名为“index”的参数，在h5端就是自己想获取的内容，但是在app端就是一个包含了很多信息的内容，并不是我自己传递的值，请问这是什么系统保留变量吗

{"target":{"dataset":{"v-813b6529":"","v813b6529":""},  
"id":"",  
"offsetLeft":286,"offsetTop":76},  
"type":"click",  
"timeStamp":8628.300000011921,"detail":{"y":73,"x":296},  
"currentTarget":{"dataset":{"v-813b6529":"","v813b6529":""},  
"id":"","offsetLeft":286,"offsetTop":76},  
"changedTouches":[{"clientX":296,  
"pageY":73,  
"pageX":296,"force":1,  
"clientY":73,"identifier":0}],  
"touches":[{"clientX":296,"pageY":73,"pageX":296,"force":1,"clientY":73,"identifier":0}]}
