怎么获取单击事件的坐标

小程序没有问题，在安卓真机上，@tap和@click的event参数都是0，@longpress都有值
{
"type": "click",
"timeStamp": 1617554318664,
"target": {
"id": "",
"dataset": {},
"offsetLeft": 0,
"offsetTop": 0
},
"currentTarget": {
"id": "",
"dataset": {},
"offsetLeft": 0,
"offsetTop": 0
},
"detail": {},
"stopPropagation": "function() { [native code] }"
}
