需要複製這樣的格式換行是重點 
copyText: function (e) {
arr= [
{name: "賬戶", value: "1888888888"},
{name: "創建時間", value: "2019-11-20 13:51:59"},
{name: "交易狀態", value: "失敗(交易超時)"},
{name: "交易克重", value: "99克"}]
// console.log(`${arr.map(item =>`${item.name}: ${item.value}`).join("\n")}`)
wx.setClipboardData({
data:`${arr.map(item =>`${item.name}: ${item.value}`).join("\n")}`,
success: function (res) {
wx.getClipboardData({
success: function (res) {
wx.showToast({
title: '複製成功'
})
}
})
}
})
},
