Vue JS 道具未定义

Question

我正在为 VUE JS 使用 Gridsome 框架

我正在使用 this.$router.push(PATH, PARAMS)

导航到新页面

this.$router.push({path: `/${value.sectionLink}/`, params: {pageOBJ: value}})

页面路由工作正常 - 但是 PROP pageOBJ 在页面中未定义，如在 VUE 检查器中所见：

它应该是一个 object（这是 VALUE 设置的值）即

我已经尝试了多种不同的技术来解决这个问题，但都没有弄明白，所以我想我在这里遗漏了什么？

gridsome 在您将新的 PAGE.VUE 文件添加到 /pages 文件夹时自动生成页面路由 -

是这个问题吗？

Gridsome 也引用了 graphQI，你应该使用图形而不是通过推送 Props 来获取数据吗？

任何帮助都会很棒 - 如果您需要任何进一步的信息，请告诉我。

谢谢 - W

根据当前答案更新：

我已经将 props:true 添加到组件中，如下所示，但问题仍然存在。

代码片段 - 摘要：

用户点击 SectionTitle 组件，然后发出页面 link （每个 SectionTitle 都是来自 : sections array of Object 的一个对象）

Answer 1

在 this.$router.push()

中传递 name 而不是 path

this.$router.push({name: ${value.sectionLink}, params: {pageOBJ: value}})

Answer 2

您应该将 props:true 添加到路由定义中：

{
 path:'/thepath/:theParam',
 component:SomeComponent,
 props:true
}
