js部分代码如下:

Page({

data: {

id: '',

ids: '',

idss: ''

},

onLoad: function (options) {

this.setData({

id: options.id

});

// var idss=this.date.id;

var ids = this.data.id;

var that = this;

wx.request({

url: 'https://www.bbjteam.com/xiaochenxu/bbjteam/index.psdinfo.php',

method: 'POST',

data: {

ids: ids

},

header: {

'content-type': 'application/x-www-form-urlencoded'

},

success: function (res) {

that.setData({

psdinfo: res.data,

});

wx.setNavigationBarTitle({

title: that.data.psdinfo.psd_name

})

}

})

}

})


运行报错:

setNavigationBarTitle:fail parameter error: parameter.title should be String instead of Undefined;


请问大神这个应该如何解决?

    你这个接口返回的是一个数组格式,而不是直接对象吧?试试

    wx.setNavigationBarTitle({
     
    title: that.data.psdinfo[0].psd_name
     
    })

      是数组,试了下你说的方法,控制台报错

      unknown: Unexpected token, expected ,

      这个报错应该和你这个代码片段无关了,查下其它地方代码

      还是粗心大意了。修改的时候不小心在上面一行代码多加了字母。谢谢大神。
