switch(index){

case 0: wx.navigateTo({url: '/pages/detail/detail?title=' + title})

break;

case 1: wx.navigateTo({ url: '/pages/detailA/detailA?title=' + title })

break;

default: wx.navigateTo({ url: '/pages/detailB/detailB?title=' + title })

}

if (index == 0) {

wx.navigateTo({

url: '/pages/detail/detail?title=' + title,

})

}else if(index==1){

wx.navigateTo({

url: '/pages/detailA/detailA?title=' + title,

})

} else{

wx.navigateTo({

url: '/pages/detailB/detailB?title=' + title,

})

}

然后在app.json中

"pages":[

"pages/index/index",

"pages/jion/jion",

"pages/detail/detail",

"pages/detailA/detailA",

"pages/detailB/detailB",

"pages/logs/logs"

],

就可以了，我已经试过了！其实用if 太麻烦，可以使用switch case的语句来

可以做if语句判断
