在未使用自定义组件时，可以正常显示，现在加入了一个自定义组件，报下面的错误

好的，我周末整理一下

问题解决了：需要加个bind(this),不知道是不是基础库改了的原因，以前是不需要加xxx.bind(this),

this.handleCheckoutChanged.bind(this)

谢谢，我也遇到这个问题了，用你的方法解决了

你好，我没能根据你提供的代码复现问题。麻烦提供更完整的代码以方便排查。

请问是什么方法要加bind(this)呢？

如何使用wx.navigateTo报错，用wx.redirectTo不报错

Component({

properties: {

model: {

type: Object,

value: {}

},

},

data: {},

methods: {

onChooseBillingAddress(e) {

let url = PageConfig.checkoutBillingAddressPage.url;

// PageUtil.navigateTo(url);

// 报错

wx.navigateTo({

url

});

// 不报错

wx.redirectTo({

url

});

}

}

});

查了一下在子组件使用，

wx.navigateTo({

    url: ‘另一个Page页面’

});

就报这样的错误，不知道为什么
