I am trying to develop guided tour with shepherd: https://www.npmjs.com/package/vue-shepherd but I cannot get the element. So here is my component for guide tour:
<template>
<div></div>
</template>
<script>
import { useShepherd } from 'vue-shepherd';
export default {
props: {
element: {
required: true,
},
id: {
type: Number,
required: true,
},
title: {
type: String,
},
text: {
type: String,
required: true,
},
position: {
type: String,
required: true,
},
},
mounted() {
this.tour.start();
},
data() {
return {
tour: null,
};
},
methods: {
createTour() {
this.tour = useShepherd({
useModalOverlay: true,
});
this.tour.addStep({
title: this.title,
text: this.text,
attachTo: { element: this.element, on: this.position },
buttons: [
{
action() {
return this.back();
},
classes: 'shepherd-button-secondary',
text: 'Back',
},
{
action() {
return this.next();
},
text: 'Next',
},
],
id: this.id,
});
this.tour.start();
},
},
created() {
this.createTour();
},
};
</script>
and here is my parent component:
<button ref="button">
Click
</button>
<guide :element="element" :title="'Tour'" :text="'Example'" :position="'bottom'" :id="1" />
and the mounted of the parent element:
mounted() {
this.element = this.$refs.button;
},
but the tour doesnt attach the the button element. it just appears in the middle of the page. Why do you think it is?
Looks like a usage problem in vue hooks. The child component's hooks fire before the parent component's hooks. Therefore, at the time of the creation of the tour, the element does not exist. Vue-shepherd does not use vue reactivity.
Use
mounted() {
this.$nextTick(() => {
this.createTour();
});
},
Codesanbox
But it's better to change the component structure. If you are using vue3 you can use my package
In this case it will look like this
<template>
<button v-tour-step:1="step1">
Click
</button>
</template>
<script>
import { defineComponent, inject, onMounted } from "vue";
export default defineComponent({
setup() {
const tour = inject("myTour");
onMounted(() => {
tour.start();
});
const step1 = {
/* your step options */
}
return {
step1,
};
}
});
</script>
I try to fetch stocks data from an API. This data should be used to create a chart.js graph.
how do I access in vue.js data to generate a chart.js line chart from the methods http(axios) call?
Is it possible to access the data directly in the mounted component or should I define a const in the section and create the variables there?
<template>
<select v-model="selected">
<option v-for="option in options" :value="option.value">
{{ option.text }}
</option>
</select>
<div>Selected: {{ selected }}</div>
<div>
<canvas id="myChart" height="200" width="650"></canvas>
</div>
<script>
export default {
mounted() {
const ctx = document.getElementById("myChart");
const myChart = new Chart(ctx, {
type: "line",
data: {
labels: [prices[0].date],
datasets: [
{
label: 'Dataset msft',
data: prices[0].price
},
{
label: 'Dataset google',
data: prices[1].price
},
],
},
});
},
data() {
return {
selected: "",
prices: [],
options: [
{ text: "msft", value: "msft" },
{ text: "GOOGL", value: "GOOGL" },
],
};
},
watch: {
selected: function () {
this.getPrice();
},
},
methods: {
getPrice: function () {
var this_ = this;
axios
.get(
"https://site/...."
)
.then((response) => {
// JSON responses are automatically parsed.
this_.prices = response.data;
})
},
},
};
</script>
Yes, you can access variables in data() from mounted().
You need to prepend variables with this. when using the Options API
ex: this.prices[0].price
As you are putting watcher on selected but I did not see any changes in the selected variable in your code. As per my understanding you are making an API call to get the graph data based on the selected option.
If Yes, Instead of generating a chart in mounted you can generate it inside your getPrice() method itself based on the response. It should be :
methods: {
getPrice: function () {
var this_ = this;
axios
.get(
"https://site/...."
)
.then((response) => {
this.generateChart(response.data);
})
},
generateChart(prices) {
const ctx = document.getElementById("myChart");
const myChart = new Chart(ctx, {
type: "line",
data: {
labels: [prices[0].date],
datasets: [
{
label: 'Dataset msft',
data: prices[0].price
},
{
label: 'Dataset google',
data: prices[1].price
}
]
}
});
}
}
Here, a very basic example:
<script>
export default {
async mounted() {
await this.$nextTick();
const ctx = document.getElementById("myChart");
this.chart = new Chart(ctx, {
type: "line",
data: {
labels: [],
datasets: [],
},
});
},
data() {
return {
selected: "",
chart: null,
options: [
{ text: "msft", value: "msft" },
{ text: "GOOGL", value: "GOOGL" },
],
};
},
watch: {
selected: function () {
this.getPrice();
},
},
methods: {
async getPrice() {
let { data } = await axios.get("https://site/....");
this.chart.data.datasets = [{ label: "dummy data" , data: [2, 3, 4]}];
this.chart.data.label = [1, 2, 3];
this.chart.update(); //very important, always update it
},
},
};
</script>
You create a property called chart and save your chart to it.
Then, after you fetch your data, you can access your chart with this.chart and then you set your datasets and labels. Whenever you make an change to the chart, use this.chart.update() to update it on the browser.
If you execute this code, you should see some dummy data in the chart
I made a VueJS 3 project with VueX to store the data.
When I print the variable data.doughnutChart.data in the following code it displays
{ "labels": [ "OK", "WARNING", "ERROR" ], "datasets": [ {
"backgroundColor": [ "#d4efdf", "#fdebd0", "#fadbd8" ], "data": [ 3,
1, 2 ] } ] }
But the graph doesn't use these data [3,1,2], the graph uses the values of the initialization in the index.js of VueX.
Here my code :
<template>
{{data.doughnutChart.data}}
<div style="height:200px;width: 200px; position:center">
<vue3-chart-js
:id="data.doughnutChart.id"
:type="data.doughnutChart.type"
:data="data.doughnutChart.data"
:options="data.doughnutChart.options"
></vue3-chart-js>
</div>
</template>
<script>
import Vue3ChartJs from '#j-t-mcc/vue3-chartjs'
export default {
name: 'App',
components: {
Vue3ChartJs,
},
beforeMount() {
this.$store.dispatch("getData");
},
computed: {
data() {
return {
doughnutChart: {
id: 'doughnut',
type: 'doughnut',
data: {
labels: ['OK', 'WARNING', 'ERROR'],
datasets: [
{
backgroundColor: [
'#d4efdf',
'#fdebd0',
'#fadbd8'
],
data: [this.$store.state.nbOk, this.$store.state.nbWarning, this.$store.state.nbError]
}
]
},
options:
{
plugins: {
legend: {
display: false
},
title: {
display: true,
text: 'Current situation'
}
},
}
}
}
}
}
}
</script>
I read the value in my index.js (VueX) :
import axios from 'axios'
import { createStore } from 'vuex'
export default createStore({
state: {
data: [],
nbError : 0,
nbWarning : 0,
},
actions: {
getData({commit}){
axios.get('http://localhost:8080/data/mock.json')
.then(res => {
commit('SET_DATA', res.data)
})}
},
mutations: {
SET_DATA(state, data){
state.data = data.data;
state.nbWarning = 0;
state.nbError = 0;
for (let i = 0; i < state.data.length; i++) {
if(state.data[i].status == 'WARNING'){
state.nbWarning += 1;
};
if(state.data[i].status == 'ERROR'){
state.nbError += 1;
};
};
}
})
However it works when, in my Vuejs project, I go in an other page and come back but not when I just open the project or refresh the page.
Do you know why ?
data property should be defined as computed in order to receive store changes:
<template>
{{data}}
</template>
<script>
export default {
data() {
return {
}
},
computed:{
data(){
return [this.$store.state.nbWarning, this.$store.state.nbError]
}
},
beforeMount() {
this.$store.dispatch("getData");
}
}
</script>
I am trying to get data from server using vue and apexcharts, but even after I called data with axios, it gives me undefined..
What have I missed?
template
<apexchart
ref="chart1"
width="100%"
:options="chartOptions" :series="series">
</apexchart>
data from url
{
"pageviews": 1313,
"new_users": 1014
}
script
export default {
data: function () {
return {
series: [],
chartOptions: {
chart: {
type: 'donut',
},
colors: ['#01cd49', '#007568'],
labels: ['new', 're'],
}
},
created: function () {
this.getByVisitor()
},
methods: {
getByVisitor() {
const url = 'url';
axios
.get(url)
.then(response => {
this.$refs.chart1.updateSeries([{
name: 'Sales',
data: response.data
}])
})
.catch(error => (this.byVisitor = error.data));
console.log(`---------------this.$refs.chart1`, this.$refs.chart1);
},
}
See Updating Vue Chart Data
There's no need to directly call the updateSeries() method on the chart component since it is able to react to changes in series. All you have to do is update your series data property
export default {
data: () => ({
series: [], // 👈 start with an empty array here
byVisitor: null, // 👈 you seem to have missed this one for your error data
chartOptions: {
chart: {
type: 'donut',
},
colors: ['#01cd49', '#007568'],
labels: ['new', 're'],
}
}),
created: function() {
this.getByVisitor()
},
methods: {
async getByVisitor() {
const url = 'url';
try {
const { data } = await axios.get(url)
// now update "series"
this.series = [{
name: "Sales",
data
}]
} catch (error) {
this.byVisitor = error.data
}
},
}
}
In my AgGrid data, I have a column which has a value of array of objects like this:
...
media:
[
{ title: 'Facebook', site: 'http://www.facebook.com'},
{ title: 'Twitter', site: 'http://www.twitter.com'}
{ title: 'Instagram', site: 'http://www.instagram.com'}
]
...
I managed to show in by cellRenderer like this
'Facebook, Twitter, Instagram'
But my problem is my floating filter , I don't know how to filter all columns which has for example has 'Facebook' media.
Here's my custom floating filter component:
import Vue from 'vue'
export default Vue.extend({
template: `
<input type="text" #change="valueChanged($event)"/>
`,
data: function() {
return {
currentValue: ''
}
},
beforeMount() {},
mounted() {},
methods: {
valueChanged(event) {
this.currentValue = event.target.value
this.params.onFloatingFilterChanged({
model: this.buildModel()
})
},
onParentModelChanged(parentModel) {
this.currentValue = !parentModel ? 0 : parentModel.filter
},
buildModel() {
if (this.currentValue === 0) {
return null
}
return {
filterType: 'text',
type: 'equalsTo',
filter: this.currentValue,
filterTo: null
}
}
}
});
