Vue multiple questions, with each question having multiple options - javascript

I have a list of properties in my database. I want the user to select the type of houses in the property.
Property
Selected property types
Property 1
['studio_apartment', 'one_bedroom', 'two_bedroom']
Property 2
['studio_apartment', 'one_bedroom']
To achieve this I am using the Vue v-for loop as follows:
<template>
<div v-for="(name, index) in propertyNames" :key="index">
NAME: {{ name }}<br />
<input
type="checkbox"
value="studio_apartment"
v-model="form.property_type"
/>Studio apartment<br />
<input
type="checkbox"
value="one_bedroom"
v-model="form.property_type"
/>One bedroom<br />
<input
type="checkbox"
value="two_bedroom"
v-model="form.property_type"
/>Two bedroom<br />
SELECTED: {{}}
</div>
</template>
<script>
import { mapGetters, mapActions } from "vuex";
export default {
data() {
return {
form: {
property_type: [],
},
};
},
</script>
The problem is when I select for example studio_apartment in property 1, then all the properties studio_apartment is checked. How do I only get the selected checkboxes for each property individually. Thanks.

This happens because there's only one form instance being shared in each loop iteration.
You could change form into an object array based on propertyNames, so that they have the same array length; then index into form with the iteration index of v-for:
<template>
<div>
<div v-for="(name, index) in propertyNames" :key="index">
NAME: {{ name }}<br>
<input type="checkbox" value="studio_apartment" v-model="form[index].property_type">Studio apartment<br>
<input type="checkbox" value="one_bedroom" v-model="form[index].property_type">One bedroom<br>
<input type="checkbox" value="two_bedroom" v-model="form[index].property_type">Two bedroom<br>
</div>
</div>
</template>
<script>
export default {
data() {
const propertyNames = ['Property 1', 'Property 2']
return {
propertyNames,
form: propertyNames.map(name => ({ property_type: [] }))
}
}
}
</script>

Delete updated v-model checkbox property in vuejs

I have a input checkbox tag which I'm trying to delete after it has been updated in my v-model please how can I go about this.
This is my input tag:
<input
v-model="checked"
type="checkbox"
id=""
value="jackets"
>
I get the v-model value property by doing this
{{checked}}
Please how can I add a delete function to my v-model property in which if I click on the delete function the checkbox would be unchecked.
If I understood you correctly try like following snippet (just set your checked property to false):
new Vue({
el: '#demo',
data() {
return {
checked: true,
filters: [{name: 'XXL', state: false}, {name: 'Grey', state: false}]
}
},
methods: {
del() {
this.filters.forEach(f => f.state = false)
},
rem(i) {
this.filters[i].state = false
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<div v-for="(filter, i) in filters" :key="i">
{{ filter.name }}
<input
v-model="filter.state"
type="checkbox"
id=""
:value="filter.name"
/>
<button #click="rem(i)">X</button>
</div>
Remove All
<input
type="checkbox"
id=""
#input="del"
/>
</div>

(Vuejs) Property or method is not defined on the instance but referenced during render

I have a simple button suppose to add an item in a list:
<label for="numit">item number:</label>
<input type="text" id="numit" :value="idxItemBuy">
<button id="buyitem" #click="buy($event.target.value)">Buy</button>
buy() {
console.log("buy fonction")
this.currentPlayer.buy(this.idxItemBuy)
}
but it's acctualy not calling the method buy
( and i don't know when i'm suppose to use $event.target.value)
You can read more about v-model => bind input with a data (https://v2.vuejs.org/v2/guide/forms.html or https://v3.vuejs.org/guide/forms.html#text)
I write you a code that works
<template>
<div>
<label>item number:</label>
<input type="text" v-model="idxItemBuy" />
<button #click="buy">Buy</button>
<ul>
<li v-for="item in items" :key="item">
{{ item }}
</li>
</ul>
</div>
</template>
<script>
export default {
data() {
return {
idxItemBuy: "",
items: [],
};
},
methods: {
buy() {
console.log("buy fonction", this.idxItemBuy);
this.items.push(this.idxItemBuy);
},
},
};
</script>

capture html within a component

capture the content of a component child, this component and this in turn calls another, in this second component there is an html, in this second component in the code javascripot capture this component to use it
first component, has as component child -- field --
<template>
<div id="login">
<field type="select" name="lang">
<option>one</option>
<option>zero</option>
</field>
</div>
</template>
second component, is field
<template>
<div class="field input">
<label>{{label}}</label>
<div v-html="htmlfield"> </div>
</div>
</template>
<script>
export default {
props: ['type'],
computed : {
htmlfield : function(){
switch (this.type) {
case 'select':
return `<select ${attr}>**__here__**</select>`; break;
}
},
},
}
</script>
__here__ I want to put the options indicated in the first component
I would like to be able to capture with javascript the html of a component
It looks like you're trying to create a universal <field> that you can pass the type of input you want.
Can I suggest a different approach?
First component
<template>
<div id="login">
<field type="select" :options="options" name="lang"></field>
</div>
</template>
<script>
export default {
data () {
return {
options: [
{ label: 'one', value: 'value1' },
{ label: 'zero', value: 'value2' }
]
}
}
}
</script>
Second component:
<template>
<div class="field input">
<label>{{ label }}</label>
<select v-if="type === 'select'">
<option v-for="option in options" :value="option.value" :key="option.value">{{ option.label }}</option>
</select>
<input v-if="type === 'text'" type="text">
<input v-if="type === 'number'" type="number">
</div>
</template>
<script>
export default {
props: ['label', 'type', 'options']
}
</script>
Here, instead of writing the <option> elements in the parent template, we create option objects in an array called options and pass it to <field> as a prop, then we can render the <option> elements in the child IF the 'type' === 'select'.

Make diffrent V-MODEL on every index that i generate

How can I have different V-MODEL on every object that i generate
I am trying to make an sample cupcake website that can generate multiple forms in one submit.
But when I generate 2 field, the inputs of the 2 generated field bound by each other inputs.
This is the code I am trying to generate:
<template>
<div>
<button #click="cupcakes.push(def)">Add Cup Cake</button>
<div v-for="(cupcake, index) in cupcakes" :key="index">
<input type="text" v-model="cupcakes[index].name">
<input type="text" v-model="cupcakes[index].description">
<input type="text" v-model="cupcakes[index].type">
<input type="text" v-model="cupcakes[index].prize">
<input type="text" v-model="cupcakes[index].color">
</div>
<button #click="onSubmit">Create Cupcate</button>
</div>
</template>
<script>
export default {
data() {
return {
cupcakes: [],
def: {
name: '',
description: 'Originals',
type: 'small',
prize: 500,
color: 'color'
}
}
},
methods: {
onSubmit() {
console.log(this.cupcakes);
}
}
}
</script>
I tried to do other things but it doesn't work.
How can I dis bind the 2 field and when I submit it will take the inputs that I type or input.
You are pushing n times the same objet (def) into your cupcakes Array. def is a reference to an object. So when you update cupcakes[n], you are just updating the def values.
What you need to do is send a copy of that object into the cupcakes object:
<button #click="cupcakes.push(JSON.parse(JSON.stringify(def)))">Add Cup Cake</button>
I think a better pattern would be to make a method that returns you a new cupcake:
<template>
<div>
<button #click="cupcakes.push(getNewCupcake())">Add Cup Cake</button>
<div v-for="(cupcake, index) in cupcakes" :key="index">
<input type="text" v-model="cupcakes[index].name">
<input type="text" v-model="cupcakes[index].description">
<input type="text" v-model="cupcakes[index].type">
<input type="text" v-model="cupcakes[index].prize">
<input type="text" v-model="cupcakes[index].color">
</div>
<button #click="onSubmit">Create Cupcate</button>
</div>
</template>
<script>
export default {
data() {
return {
cupcakes: []
};
},
methods: {
onSubmit() {
console.log(this.cupcakes);
},
getNewCupcake() {
return {
name: "",
description: "Originals",
type: "small",
prize: 500,
color: "color"
}
}
}
};
</script>

How to use v-model with multiple in a custom select component?

i have the following vue component
<template>
<div id="input-div">
<label v-if="label">{{ label }}</label>
<select :multiple="multiple" :value="value" #change="change($event.target.value)">
<slot></slot>
</select>
<div class="error"><slot name="error"></slot></div>
</div>
</template>
<script>
export default {
name: 'ha-select',
props: ['label', 'value', 'multiple'],
methods: {
change(value) {
this.$emit('input', value);
}
}
}
</script>
and since it is a select component i want it to be usable with v-model which works when the multiple attribute is not set but when i set multiple pass v-model an Array instead of appending the selected value to the Array, the array just gets replaced by the value of the current selected option. maybe it has something to do with the way i am emitting the input event. So how do i create a custom select component with multiple support?
I've modified the code slightly to use a local variable bound to the select with v-model and emit the bound value. This results in emitting the array of selected values when multiple is true.
console.clear()
const CustomSelect = {
template: `
<div id="input-div">
<label v-if="label">{{ label }}</label>
<select :multiple="multiple" v-model="selected" #change="$emit('input', selected)">
<slot></slot>
</select>
<div class="error"><slot name="error"></slot></div>
</div>
`,
name: 'ha-select',
props: ['label', 'value', 'multiple'],
data(){
return {
selected:this.value
}
},
}
new Vue({
el:"#app",
data:{
albums: []
},
components: {
CustomSelect
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.js"></script>
<div id="app">
<custom-select label="Pink Floyd Albums" v-model="albums" :multiple="true">
<option value="1">Dark Side of the Moon</option>
<option value="2">Animals</option>
<option value="3">The Wall</option>
</custom-select>
<div>
Selected Albums {{albums}}
</div>
</div>
