In my vue.js application, I am trying to render the html content dynamically in child component's slot. If I enter the text only then there is no issue, it works with fine.
Here is my code:
ChildComponent.vue
<template>
<div :class="type" class="message" v-if="type">
<slot />
</div>
</template>
<script>
export default {
...
props: ['type'],
...
}
</script>
ParentComponent.vue
<script>
import Alert from '#/Alert';
export default {
components: {
Alert,
},
data() {
return {
...
alert: {
error: '',
message: '',
}
};
},
created () {
this._onLoad()
},
methods: {
_onLoad() {
axios.get(`api.call.here`).then((res) => {
...
}).catch(error => {
this.alert.error = error.type;
this.alert.message = `<p>message here</p>`; // from response
});
},
}
}
</script>
Here is the screenshot of the issue:
What you trying to do can be achieved with v-html. You can use it while calling your ChildComponent.vue. This is a small example for your case:
<Alert>
<span v-html="alert.message"></span>
</Alert>
I have 2 projects/folders (with Lerna on the root).
The first one is uicomponents with some components and the second one is testing a simple app which uses some component from uicomponents.
I created a simple counter component (Counter.vue) :
<template>
<div>
<h3>Total clicks: {{ count }}</h3>
<div class="button-container">
<button class="inc" #click.prevent="increment">Add</button>
<button class="dec" #click.prevent="decrement">Subtract</button>
</div>
</div>
</template>
<script>
import { defineComponent, ref } from 'vue';
export default defineComponent({
name: 'Counter',
props: {
startingNumber: {
type: Number,
required: false,
default: 0,
},
},
setup(props) {
const count = ref(props.startingNumber);
const increment = () => {
count.value += 1;
alert(count.value);
};
const decrement = () => {
count.value -= 1;
};
return {
count,
increment,
decrement,
};
},
});
</script>
And I import it in my app on a simple page :
<template>
<div class="hello">
<h1>{{ msg }}</h1>
<counter :starting-number="5"></counter>
</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import Counter from '#uicomponents/counter';
export default defineComponent({
name: 'HelloWorld',
components: {
Counter,
},
props: {
msg: {
type: String,
required: false,
default: 'Me',
},
},
});
</script>
Lerna correctly replace all my components path and I retrieve my components Counter in my pages with all HTML. Buttons works well and my alert are displays with the correct value BUT my html are not refreshed.
This text <h3>Total clicks: {{ count }}</h3> stay "Total clicks: 0". My "count" ref is well updated because the alert displayed it correct but not in html.
I have a similar problem with lost reactivity. My setup is a bit different, but in the end it's the same result.
I'm trying to build a small plugin system which loads external components
Roughly I try to do this
// pluginSystem.js is accessible through window.myps
// ...
init(app) {
vueApp = app;
},
// ...
loadPlugin(data) {
vueApp.component(data.component.name, data.component);
}
And my external component looks like this
// main.js
import Counter from './components/Counter.vue';
window.myps.loadPlugin({
component: Counter,
});
Button click in counter, etc. works, console logging is fine as well, but component data is not updated.
I also tried defineComponent and defineAsyncComponent, but as you I had no luck with it...
Try it
import { defineAsyncComponent, defineComponent } from "vue"
components: {
Counter:defineAsyncComponent(() => import("#uicomponents/counter"))
}
I am creating my design portfolio using Vue CLI 3. The architecture of my website is very simple. I have a home page, about page, work page, and several individual project pages:
Home
About
Work
Project
Project
Project
The work page consists of several links that would click through to the individual project pages. The work component is set up like so:
<template>
<div>
<projectLink v-for="data in projectLinkJson" />
</div>
</template>
<script>
import projectLink from '#/components/projectLink.vue'
import json from '#/json/projectLink.json'
export default {
name: 'work',
data(){
return{
projectLinkJson: json
}
},
components: {
projectLink
}
}
</script>
As you can see, I'm importing JSON to dynamically render the content. Next, the projectLink component can be seen in the code block below. Within this component I am passing a param into <router-link> called projectName
<template>
<router-link :to="{ name: 'projectDetails', params: { name: projectName }}">
<h1>{{ title }}</h1>
</router-link>
</template>
<script>
export default {
name: 'projectLink',
props: {
title: String,
projectName: String
}
}
</script>
My routes.js file is setup like so:
const routes = [
{ path: '/', component: home },
{ path: '/about', component: about },
{ path: '/work', component: work },
{
path: "/work/:name",
name: "projectDetails",
props: true,
component: projectDetails
},
];
and my JSON is like so:
{
"0": {
"title": "test",
"projectName": "test"
}
}
Lastly, my projectDetails component is the component that is where I am having this issue:
<template>
<div>
<div
v-for="(data,index) in projectDetailsJson" v-if="index <= 1">
<h1>{{ data.title }}</h1>
<p>{{ data.description }}</p>
</div>
</div>
</template>
<script>
import json from '#/json/projectDetails.json'
export default {
name: 'projectDetails',
data(){
return{
projectDetailsJson: json
}
},
props: {
description: String,
title: String
}
}
</script>
I am successfully routing to the URL I want, which is /project/'name'. I want to use the projectDetails component as the framework for each of my individual project pages. But how do I do this dynamically? I want to retrieve data from a JSON file and display the correct object from the array based on the name that was passed to the URL. I do not want to iterate and have all of the array display on the page. I just want one project to display.
Quick solution:
projectDetails.vue
<template>
<div>
<div>
<h1>{{ projectDetails.title }}</h1>
<p>{{ projectDetails.description }}</p>
</div>
</div>
</template>
<script>
import json from '#/json/projectDetails.json';
export default {
name: 'projectDetails',
props: {
name: String,
},
data() {
return {
projectDetails: Object.values(json).find(project => project.title === this.name),
};
},
};
</script>
In my opinion, a better solution:
I don't get the idea that you keep project data in 2 separate JSON files. During compilation, both files are saved to the resulting JavaScript file. Isn't it better to keep this data in 1 file? You don't have to use all of your data in one place. The second thing, if you have a project listing then you can do routing with an optional segment, and depending on whether the segment has a value or not, display the listing or data of a particular project. Then you load project data only in one place, and when one project is selected, pass its data to the data rendering component of this project. Nowhere else do you need to load this JSON file.
routes.js

const routes = [
{path: '/', name: 'home', component: home},
{path: '/about', name: 'about', component: about},
{path: '/work/:name?', name: 'work', component: work, props: true},
];
export default routes;

};
},

components: {
Projects,

},
computed: {
currentProject() {
if (this.slug) {
return this.projects.find(project => project.slug === this.slug);
}
}
}
};
const router = new VueRouter({

Great work thus far, Austin! You're very close having this working. There are a few different ways you could parse out the correct data from your JSON file into the projectDetails component, but I'll just demo my preferred way.
First, you're going to need a bit of vanilla JS to search through your JSON file and return only the row that you want. I would do this as a method since the data isn't going to be changing or requiring the component to re-render. So, after your props, I would add something like this:
methods: {
findProject(projectName) {
return Object.values(json).find(project => project.title === projectName)
}
}
Note that this is going to return the first project that matches the project name. If you have projects with the exact same project name, this won't work.
Next, you'll just need to update the default value of projectDetailsJson to call this method and pass the route's project name. Update data with something like this:
data() {
return {
projectDetailsJson: this.findProject(this.$route.params.name)
}
}
If that doesn't work, we may need to set the projectDetailsJson in the created lifecycle hook, but try the above code first.
If I understood correctly, you want to keep a parent component as a layout for all of your page?
If I always understood correctly, you must use the children property of vuerouter
https://router.vuejs.org/guide/essentials/nested-routes.html
import layout from 'layout';
const projectRoute = {
path: '/project',
component: Layout, // Load your layout
redirect: '/project/list',
name: 'Project',
children: [
{
path: "list", // here the path become /project/list
component: () => import('#/views/project/List'), // load your components
name: "List of project",
},
{
path: "detail/:id",
component: () => import('#/views/project/Detail'),
name: "Detail of project",
}
],
};
So you can create your layout and add everything you want, this will be available on all child components, and you can use $emit, $refs $props ect...
+
You can create an file routes/index.js and create folder routes/modules . Inside this, you can add your routes/modules/project.js and load the modules in routes/index.js
import Vue from 'vue';
import VueRouter from 'vue-router';
Vue.use(VueRouter);
import projectRoutes from "./modules/project";
const routes = [
projectRoutes,
{
// other routes....
},
]
export default new VueRouter({
routes,
mode: 'history',
history: true,
});
#see the same doc : https://router.vuejs.org/guide/essentials/nested-routes.html
Finally, you just have to do the processing on the layout, and use the props to distribute the values both in detail and in the project list; and use the filter methods described just above
I hope I have understood your request, if this is not the case, let me know,
see you
Edit: Here is a very nice architecture with vue, vuex and vuerouter. maybe inspire you
https://github.com/tuandm/laravue/tree/master/resources/js
For everyone, to take this one step further. How would you show only the projectLinks that match the current URL? So if I have three different JSON projectTypes: design, code, motion. If the URL contains motion in it, how do I filter my projectLink components to show only those that have a matching JSON value of either design, code or motion. Essentially I'm just trying to filter.
Here is a basic setup for what I would like to do:
HTML Side
test.html
<div id="app">
<my-comp temp="1" cat="{ name:'Geoff', age:3 }"></my-comp>
</div>
Vue Side
app.js:
import myComp from './components/myComp.vue'
app = new Vue({
el: "#app",
components: {
myComp
}
});
myComp.vue
<template>
<div v-html='template'>
</div>
</template>
<script>
export default {
props: [
'temp',
'cat'
],
data () {
temp1: `<input name="name" value="cat.name">
<input name="age" value="cat.age">`,
// other template
// ...
},
computed: {
template() {
return this.temp == 1 ? this.temp1 : this.temp2;
}
}
}
</script>
My problem is when I open the html file in the browser, I get:
cat.name
cat.age
appearing in the input. Technically, my form isn't responsive to existing data. How can I solve this?
In your test.html you have to change this:
<my-comp :temp="1" :cat="{ name:'Geoff', age:3 }"></my-comp>
The double dots have to added otherwise it will be interpreted as an string and not as an object.
With value you are on the right track. The only you have to change is this because you want to insert a variable into your 'string'
data() {
return {
temp1: `<input name="name" value="${this.cat.name}">
<input name="age" value="${this.cat.age}">`
}
}
Don't forget to add 'input type' as well.
I am new to vuejs I want re-build my v-for loop after update vuex object. see following example code.
<div class="row search-result-row" v-for="report in reports" :key="report">
<p>{{ report.description }}</p>
</div>
here is my vuex object called globalReports. when I equal globalReports to reports it doesn't work.
computed: {
updateReports: function() {
return this.reports = this.$store.state.globalReports;
}
},
How can I do this without page reload?
Try with {{updateReports}}. Computed will not be executed util it is monitored or called, just called {{updateReports}}
<div class="row search-result-row" v-for="report in reports" :key="report">
<p>{{ report.description }}</p>
</div>
{{updateReports}}
And don't return anything just update/Assign value of this.reports
computed: {
updateReports: function() {
this.reports = this.$store.state.globalReports;
}
},
by using mapState, you can map the value of globalReports to reports automatically.
Everytime globalReports change, reports gets updated automatically, and the rebuild will happen automatically when it gets updated.
<script>
import { mapState } from "vuex";
export default {
computed: mapState({
reports: "globalReports"
})
};
</script>
Vuex is reactive so when you update the state,this change will affect all components where you use the state properties.To be more specific:
I will show you an example:
//VUEX STORE
state: {
property1
},
getters: {
getProperty1(state) {
return state.property1
}
},
mutations: {
setProperty1(state, payload) {
state.property1 = payload
}
},
actions: {
changeProperty1({commit}, payload) {
commit('setProperty1', payload)
}
}
And below is the component in which you interact with state
<template>
<p>this is from state of store {{ getProperty1 }</p>
<input type="text" v-model="value">
<button #click="changeState">Sumbit</button>
</template>
<script>
export default {
data() {
return {
value: ''
}
},
computed: {
getProperty1() {
return this.$store.getters.getProperty1
}
},
methods: {
changeState() {
this.$store.dispatch('changeProperty1', this.value)
}
}
}
</script>
Getters are to get the state properties
Mutations to change the state properties
Actions to perform async code and then to call mutations to change the state
