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

谢谢，我也遇到这个问题了，用你的方法解决了
请问是什么方法要加bind(this)呢？
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)
好的，我周末整理一下
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。
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
