问题 I am trying to make my app app connect to pusher on a private channel. But I am getting the following error: pusher.js?b3eb:593 POST http://localhost:8000/broadcasting/auth 404 (Not Found) What maybe the cause of the error and how to resolve it. 回答1: Look in config/app.php if you have uncommented App\Providers\BroadcastServiceProvider::class, 回答2: There are two Service Providers with Same name but different namespace in config/app.php Illuminate\Broadcasting\BroadcastServiceProvider::class,

问题 I am fairly new to Vue and have started with a project with vue-cli. I am looking into conditional rendering based on a prop sent from parent. Home.vue (parent) <template> <Header have-banner="true" page-title="Home"> </Header> </template> <script> import Header from "./Header"; export default { components: { Header, }, name: "Home", data() { return { header: "Hello Vue!", }; }, }; </script> Header.vue (child) <template> <header> <div v-if="haveBanner == 'true'"> ... </div> ... </header> <

问题 In vue.js what is the right way to edit prop without changing parent data? What I mean by that is whenever we pass any property from parent to child in vue.js then if we make any change to that property in child component then the change is also reflected in parent's component. Is there any way in vue.js to make a local copy of passed property in a child? I googled this but everywhere it is written that we can achieve this by doing this. props:["user"], data(){ return { localUser: Object

问题 Here is my current template: <a-droppable v-for="n in curSize" :key="n - 1" :style="{width: `${99.99 / rowLenMap[orderList[n - 1]]}%`, order: orderList[n - 1]}"> <a-draggable :class="{thin: rowLenMap[orderList[n - 1]] > 10}"> <some-inner-element>{{rowLenMap[orderList[n - 1]]}}</some-inner-element> </a-draggable> </a-droppable> The problem is that i have to write rowLenMap[orderList[n - 1]] multiple times, and i'm afraid vue.js engine will also calculate it multiple times. What i want is

问题 I'm learning TDD whilst building my Vue app, and trying to abide by the strict laws of only writing enough production code to satisfy a failing unit test. I am really enjoying this approach, but I have run into a roadblock in regards to adding methods to a Vue instance, and testing that they have been called when the event fires from the element in the template. I cannot find any suggestions as to how I can mock a Vue method given that if I mock the proxied method, it ends up not being called
