var inAmount = e.detail.value.inputamount;
if(inDetail.toString().length <= 0 || inAmount.toString().length <= 0){
console.log("can not empty");

});
},1000);
},
//删除行
deleteRow: function(e){
var that = this;
var index = e.target.dataset.indexKey;
var tempAccountData = wx.getStorageSync("accountData") || [];
tempAccountData.splice(index,1);
