• 当前 Bug 的表现（可附上截图）

• 预期表现

• 复现路径

• 提供一个最简复现 Demo

//删除明细

deleteDetail(e){

    //e.currentTarget.id

    //e.currentTarget.dataset.index

    var that = this

    var pojos

    console.log(“deleteDetail”)

    console.log(that.data)

    console.log(that.data.pojos0.lenght)

    for (var i = 0; i<that.data.pojos0.lenght;i++){

        if (i != e.currentTarget.dataset.index){

            pojos.push(that.data.pojos0[i])

        }

    }

    that.setData({

        pojos0:pojos

    })

}

模拟与真机上都调试过：页面渲染是正常的，打印出来却是 undefined
