Here i have an #click event
<h2 #click="action(customer.id)">{{ customer.name }}</h2>
When any result is clicked append this result to the input. Any ideas ?
<input class="search" type="text" name="search" v-model="search" placeholder="Search posts..."
#focus="magic_flag = true">
<div v-if="magic_flag">
<div class="post" v-for="customer in filteredCustomer">
<h2 #click="action(customer.id)">{{ customer.name }}</h2>
</div>
</div>
How can i append the clicked result from the search to the input?
js here updated:
methods: {
action(item) {
this.selected = item
this.search = item.name
this.magic_flag=false;
}
},
I display the rest of the content here updated:
<div v-if="selected">
<div class="post" v-for="customer in filteredCustomer">
<div v-if="customer === selected">
<h1>{{ customer.name }}</h1>
<h1>{{ customer.id }}</h1>
<h1>{{ customer.address }}</h1>
</div>
</div>
</div>
Instead of passing customer.id to the action method, you can pass customer object as parameter to action.
You can do something like this.
var vm = new Vue({
el: '#app',
data: {
search: "",
filteredCustomer:[{name:'test1',id:1},{name:'test2',id:2},{name:'test3',id:3}]
},
methods: {
action (customer) {
this.search=customer.name
this.filteredCustomer=this.filteredCustomer.filter(o=> o.id!=customer.id)
}
}
});

I use VeeValidate and Yup for form validation and don't know why my input field with type="number" is converted to string on submit.
When I input 78 and submit the form the output of the console.log in the onSubmit(values) function is the following:
values: {
prioritaet: "78"
}
Am I doing something wrong here or is this the normal behavior of VeeValidate and Yup? I would like to have a number instead of a string after submit.
My code looks like this:
<template>
<div class="container m-3">
<div class="row bg-primary align-items-center py-2">
<div class="col">
<h3 class="text-light mb-0">Format {{ this.action }}</h3>
</div>
<div class="col-auto">
<h5 class="text-light mb-0">{{ this.formatTitle }}</h5>
</div>
</div>
<Form #submit="onSubmit" :validation-schema="formatSchema" v-slot="{ errors }" ref="formatForm">
<div class="row mt-4">
<div class="col">
<h5>Formatdaten</h5>
</div>
</div>
<div class="row mb-2">
<div class="col-4">
<label for="prioritaet-input">Priorität: </label>
</div>
<div class="col">
<Field type="number" name="prioritaet" id="prioritaet-input" class="w-100" />
</div>
</div>
<div class="row justify-content-end">
<div class="col-auto me-auto">
<button class="btn btn-outline-primary">Änderungen übernehmen</button>
</div>
<div class="col-auto">
<button class="btn btn-outline-primary">Abbrechen</button>
</div>
<div class="col-auto">
<button type="sumbit" class="btn btn-outline-primary">Speichern</button>
</div>
</div>
<div class="row mt-4">
<template v-if="Object.keys(errors).length">
<span class="text-danger" v-for="(message, field) in errors" :key="field">{{ message }}</span>
</template>
</div>
</Form>
</div>
</template>
<script>
import { Form, Field } from "vee-validate";
import deLocale from "../assets/yup-localization.js";
import * as Yup from "yup";
import { markRaw } from "vue";
import { mapActions, mapState } from "vuex";
Yup.setLocale(deLocale);
export default {
name: "FormatBearbeitungsSchirm",
props: ["material_id"],
data() {
let action = "neu";
let formatTitle = "Format neu";
let formatSchema = markRaw(Yup.object().shape({
prioritaet: Yup.number().min(1).max(100).integer().label("Priorität"),
}));
return { formatSchema, action, formatTitle };
},
created() {
},
components: {
Form,
Field,
},
methods: {
onSubmit(values) {
console.log("values", values);
},
},
};
</script>
It looks like there is currently no support for specifying the .number modifier on the internal field model value of <Field>, so the emitted form values would always contain a string for number-type fields.
One workaround is to convert the value in the template, updating <Form>'s values slot prop in <Field>'s update:modelValue event:
<Form #submit="onSubmit" v-slot="{ values }">
<Field 👆
type="number"
name="prioritaet" 👇
#update:modelValue="values.prioritaet = Number(values.prioritaet)"
/>
<button>Submit</button>
</Form>
demo
Another simple workaround is to convert the property inside onSubmit before using it:
export default {
onSubmit(values) {
values.prioritaet = Number(values.prioritaet)
// use values here...
}
}
You must use the .number modifier.
You can read about it here
If you want user input to be automatically typecast as a Number, you can add the number modifier to your v-model managed inputs:
const app = new Vue({
el: "#app",
data: () => ({
mynumber1: undefined,
mynumber2: undefined
}),
methods: {
submit() {
console.log(typeof this.mynumber1, this.mynumber1)
console.log(typeof this.mynumber2, this.mynumber2)
}
}
})
<script src="https://cdn.jsdelivr.net/npm/vue#2.6.14/dist/vue.js"></script>
<div id="app">
<form>
<!-- number modifier -->
<input type="number" v-model.number="mynumber1" placeholder="Type here" />
<!-- no modifier -->
<input type="number" v-model="mynumber2" placeholder="Type here" />
<input type="button" #click="submit" value="submit" />
</form>

The Pagination bar is working fine but I have 50 records on the same page ... Thank you
Use a computed property to slice the post array in the parent component:
computed: {
paginatedposts() {
return this.posts.slice(this.perPage*(this.currentPage-1), (this.perPage*(this.currentPage-1))+this.perPage);
}
}
Now you just need to bind this computed property:
<PostList
id="PostList"
v-for="post in paginatedposts"
:key="post.id"
:post="post"
/>

</div>
<div class="row mt-2">
<div class="col-md-12">

</div>
The problem is here:
v-model="this.newLeague.fullname"
You cannot use this. with v-model. Instead it should be:
v-model="newLeague.fullname"
You should also remove all other references to this within your template. In many cases they are harmless but sometimes, such as with v-model, they will cause problems.
Complete examples below. Note how the first input does not function correctly when editing the text.
new Vue({
el: '#app1',
data () {
return { newLeague: { fullname: 'League 1' } }
}
})
new Vue({
el: '#app2',
data () {
return { newLeague: { fullname: 'League 1' } }
}
})
<script src="https://unpkg.com/vue#2.6.11/dist/vue.js"></script>
<div id="app1">
<input type="text" v-model="this.newLeague.fullname">
{{ newLeague.fullname }}
</div>
<div id="app2">
<input type="text" v-model="newLeague.fullname">
{{ newLeague.fullname }}
</div>
I followed the way #skirtle wrote the data section and it worked.
My original syntax was:
data: function () {
return {
newLeague: {"fullname":"a", "notes":"b", "group_image_path": "c"} }
}
to
data () {
return { newLeague: { fullname: 'League 1' } }
}
I am creating an interactive Timeline in Vue.js and have a base code set up. What currently happens is when you select a year, content shows up but to make it disappear you need to click it again.
What I am trying to do is make the content of the previous year disappear when you click another year.
The Codepen I created is linked below:
Vue JS Timeline
As you can see, my Vue JS code has different set ups for showing the data.
var vue = new Vue({
el:"#app",
data: {
nowShowing: false,
nowShowing2: false,
nowShowing3: false,
nowShowing4: false,
isShowing:false,
message: 'test1',
message2: 'test2',
message3: 'test3',
message4: 'test4',
message5: 'test5',
}});
Then going into the HTML you have a button class
<button class="c-History__year" #click="isShowing ^= true">1880</button>
And the div class:
<div v-show="isShowing">
<p class="c-History__summary">
{{message}}
</p>
</div>
Is this possible to complete in Vue with transitioning or would CSS suffice?
I've bundled all the isShowing variables into just one and the divs are now looking for whether the isShowing var has a specific number and when does, the div will be shown and all others will be hidden.
JS:
const vue = new Vue({
el:"#app",
data: {
showing: -1,
message: 'test1',
message2: 'test2',
message3: 'test3',
message4: 'test4',
message5: 'test5',
},})
HTML:
<div id="app">
<div class="o-Container o-Container--padded">
<div class="c-History">
<div class="c-History__timeline">
<div class="c-History__years">
<span class="c-History__line"></span>
<button class="c-History__year" #click="showing = 0">1880</button>
<button class="c-History__year" #click="showing = 1">1938</button>
<button class="c-History__year" #click="showing = 2">1971</button>
<button class="c-History__year" #click="showing = 3">1982</button>
<button class="c-History__year" #click="showing = 4">2007</button>
</div>
</div>
</div>
<transition name="bounce">
<div v-show="showing == 0">
<p class="c-History__summary">
{{message}}
</p>
</div>
</transition>
<transition name="bounce">
<div v-show="showing == 1">
<p class="c-History__summary">
{{message2}}
</p>
</div>
</transition>
<transition name="bounce">
<div v-show="showing == 2">
<p class="c-History__summary">
{{message3}}
</p>
</div>
</transition>
<transition name="bounce">
<div v-show="showing == 3">
<p class="c-History__summary">
{{message4}}
</p>
</div>
</transition>
<transition name="bounce">
<div v-show="showing == 4">
<p class="c-History__summary">
{{message5}}
</p>
</div>
</transition>
</div>
</div>
</div>
You can do it with a different a simpler approach, first you can change your data structure like this:
var vue = new Vue({
el:"#app",
data: {
message: 'test1',
message2: 'test2',
message3: 'test3',
message4: 'test4',
message5: 'test5',
contentToShow: ''
},
methods: {
showContent(messageIndex) {
this.contentToShow = this[messageIndex]
}
}
})
the idea is to have a method where you are going to pass the index of message property, and set only one visible contentToShow
So your component updated will be
<div id="app">
<div class="o-Container o-Container--padded">
<div class="c-History">
<div class="c-History__timeline">
<div class="c-History__years">
<span class="c-History__line"></span>
<button class="c-History__year" #click="showContent('message')">1880</button>
<button class="c-History__year" #click="showContent('message2')">1938</button>
<button class="c-History__year" #click="showContent('message3')">1971</button>
<button class="c-History__year" #click="showContent('message4')">1982</button>
<button class="c-History__year" #click="showContent('message5')">2007</button>
</div>
</div>
</div>
<transition name="bounce">
<div v-show="contentToShow">
<p :key="contentToShow" class="c-History__summary">
{{contentToShow}}
</p>
</div>
</transition>
</div>
</div>
</div>
I have a problem on reactivating the button even if the conditional statement works.
it looked like the v-model wasn't communicating with the data but with a simple interpolation the value was updated.
I don't really know where I'm doing wrong on the code.
<template>
<div class="col-sm-6 col-md-4">
<div class="panel panel-success">
<div class="panel-heading">
<h3 class="panel-title">{{stock.name}}
<small>(Price: {{stock.price}})</small>
</h3>
</div>
<div class="panel-body">
<div class="pull-left">
<input v-model="quantity" type="number" class="form-control" placeholder="Quantity">
</div>
<div class="pull-right">
<button class="btn btn-success" #click="buyStock" :disabled="isDisabled">Buy</button>
</div>
<p>{{quantity}}</p>
</div>
</div>
</div>
</template>
<script>
export default {
props: [
"stock",
],
data() {
return {
quantity: 0,
}
},
methods: {
buyStock() {
const order = {
stockId: this.stock.id,
stockPrice: this.stock.price,
quantity: this.quantity
};
console.log(order);
this.$store.dispatch("buyStock", order);
this.quantity = 0;
}
},
computed: {
isDisabled() {
if (this.quantity <= 0 || !Number.isInteger(this.quantity)) {
return true;
} else {
return false;
}
}
}
}
</script>
By default, the v-model directive binds the value as a String. So both checks in your isDisabled computed will always fail.
If you want to bind quantity as a number, you can add the .number modifier like so:
<input v-model.number="quantity" type="number" ... >
Here's a working example:
new Vue({
el: '#app',
data() {
return { quantity: 0 }
},
computed: {
isDisabled() {
return (this.quantity <= 0 || !Number.isInteger(this.quantity))
}
}
})
<template>
<div class="col-sm-6 col-md-4">
<div class="panel panel-success">
<div class="panel-heading">
<h3 class="panel-title">{{stock.name}}
<small>(Price: {{stock.price}})</small>
</h3>
</div>
<div class="panel-body">
<div class="pull-left">
<input v-model="quantity" type="number" class="form-control" placeholder="Quantity">
</div>
<div class="pull-right">
<button class="btn btn-success" #click="buyStock" :disabled="isDisabled">Buy</button>
</div>
<p>{{quantity}}</p>
</div>
</div>
</div>
