运维中心-错误大都是undefined is not a function...
昨天小程序的运维中心刚上线，今天迫不及待的来看看线上版本有哪些错误，打开“运维中心” - “错误查询”，都是和下面类似的错误。
请问是程序写法的问题么？谢谢
undefined is not a function (evaluating ‘wx.showLoading’);App catch error in mShowLoading function
undefined is not a function (evaluating ‘wx.hideLoading()’);App catch error in mHideLoading function
undefined is not a function (evaluating ‘wx.addPhoneContact’);at api showModal success callback function
undefined is not a function (evaluating ‘wx.showLoading’);App catch error in mShowLoading function
源程序：
mShowLoading: function (text) {
var that = this
if(text == ‘’){
text = “正在加载数据”
}
if (!this.showLoading){
wx.showLoading({
title: text,
mask: true,
success:function(res){
that.showLoading = true
}
})
}
},
mHideLoading: function () {
wx.hideLoading();
this.showLoading = false
},
