I have a level 2 input field component that i am using. I want to reset on button click from the parent component. I am trying to pass the data to base initial input field and then emitting back to the parent.
My question is that when i try to reset the data on button click the value from the parent component its not working.
Data is not set to null and the values remain as 123.
What wrong I am doing in the following code.
Any help would be appreciated.
Base Input
<template>
<input
v-model="myValue"
type="number"
inputmode="numeric"
#input="$emit( 'input', $event.target.value )"
/>
</template>
<script>
export default {
data () {
return {
myValue: undefined
};
}
}
};
</script>
Level 01
<template>
<div class="c-floating-label">
<input-number #input="passValue" />
</div>
</template>
<script>
import InputNumber from '../../atoms/form-controls/BaseInput';
export default {
components: {
InputNumber
}
methods: {
passValue: function (value) {
this.$emit('input', value);
}
}
};
</script>
Main Component
<div>
<level-01
:required="true"
:v-model="datax.cardNumber"
value="datax.cardNumber"
/>
<button #click="reset">click me</button>
</div>
<script>
data () {
return {
datax: {
cardNumber: undefined
}
};
},
created() {
this.datax.cardNumber = 123;
},
methods: {
reset () {
this.datax.cardNumber = null;
},
</script>
You missed binding on MainComponent
<level-01
:required="true"
:v-model="datax.cardNumber"
:value="datax.cardNumber"
/>
Note :value="datax.cardNumber" is correct
Second, in level-01 you do not bind value prop (not defined at all)
<template>
<div class="c-floating-label">
<input-number #input="passValue" :value="$attrs.value"/>
</div>
</template>
<script>
import InputNumber from '../../atoms/form-controls/BaseInput';
export default {
components: {
InputNumber
},
methods: {
passValue: function (value) {
this.$emit('input', value);
}
}
};
</script>
And finally BaseComponent:
<template>
<input
:value="$attrs.value"
type="number"
inputmode="numeric"
#input="$emit( 'input', $event )"
/>
</template>
<script>
export default {
data () {
return {
// myValue: undefined
};
}
}
};
</script>

I have a parent form template and each question of the form is inside a child component, like this
<template>
<question1
#display-answer-1="setAnswer1"
/>
<!-- other child components here... -->
</template>
<script>
import Question1 from '...path...';
export default{
components: { Question1 },
data() {
answer1: ''
},
methods: {
setAnswer1(answer1) {
this.answer1 = answer1;
}
}
};
and my child component is like this
<template>
<input type="text" v-model="answer1"/>
<div>
<button
type="button"
#click="saveQ2"
>Save
</button>
</div>
</template>
<script>
export default {
data() {
return {
answer1: ''
};
},
methods: {
saveQ2() {
const answer1 = this.answer1;
this.$emit('display-answer-1', answer1);
}
}
};
This code works, but in this way I'm forced to put a button whenever there is a question to pass data from the child to the form template parent. Is there a smart alternative not to put a save button under each question?
you can use the blur event whenever an input gets unfocused it'll fire the event .
<template>
<input #blur="saveQ2" type="text" v-model="answer1"/>
</template>
<script>
export default {
data() {
return {
answer1: ''
};
},
methods: {
saveQ2() {
const answer1 = this.answer1;
this.$emit('display-answer-1', answer1);
}
}
};
I have an input component that should call a method getUserSearch when the user types, and update the variable v_on_search with the variable v_model_search value.
I am displaying the content with the variables: v_model_search and v_on_search to test, although only the v-model seems to be working.
<template>
<div>
<input type="text" placeholder="search here" v-model="v_model_search" v-on:oninput="getUserSearch()">
<p>{{v_model_search}}</p>
<p>{{v_on_search}}</p>
</div>
</template>
<script>
export default {
name: 'SearchBox',
data () {
return {
v_model_search: '',
v_on_search: ''
}
},
methods: {
getUserSearch ()
{
this.v_on_search = this.v_model_search
}
}
}
</script>
Try
v-on:input="getUserSearch()"
or shorter
#input="getUserSearch()"
Vue recognizes HTML events but they don't have the "on" prefix
I have two components, is there a way to store value from another component's data?
Here is Create.vue
<template>
<div id="main">
<Editor />
//some codes here
</div>
</template>
<script>
import Editor from './_Create_Editor.vue'
export default {
components: { Editor },
data: () => ({
text: ''
}),
}
</script>
And here is the _Create_Editor.vue.
<template>
//sample input for demonstration purposes
<input type="text" class="form-control" v-model="text"/>
</template>
The code above returns an error:
Property or method "text" is not defined on the instance but referenced during render
I want everytime I type the data: text from Create.vue has the value of it.
How can I possibly make this? Please help.
You can do this by using $emit.
Create.vue
<template>
<div id="main">
<Editor
#edit={onChangeText}
/>
//some codes here
</div>
</template>
<script>
import Editor from './_Create_Editor.vue'
export default {
components: { Editor },
data: () => ({
text: ''
}),
methods: {
onChangeText: function (value) {
this.text = value
}
}
}
</script>
_Create_Editor.vue
<template>
//sample input for demonstration purposes
<input
type="text"
class="form-control"
#change="onChange"
/>
</template>
<script>
export default {
methods: {
onChange: function (event) {
this.$emit('edit', event.target.value)
}
}
}
</script>
I want to search for elements using an input field within a form. I am passing a value from a component to another and the content changes but only after pressing enter. Is there a way to automatically update the list, after every new letter is typed?
Here is my code:
Parent(App):
<template>
<div id="app">
<Header v-on:phrase-search="passPhrase" />
</div>
</template>
<script>
import Header from ...
export default {
name: "App",
components: {
Header,
},
data() {
return {
posts: [],
searchedPhrase: ""
};
}
computed: {
filteredPosts() {
let temp_text = this.searchedPhrase;
temp_text.trim().toLowerCase();
return this.posts.filter(post => {
return post.name.toLowerCase().match(temp_text);
});
}
},
methods: {
passPhrase(phrase) {
this.searchedPhrase = phrase;
}
}
};
</script>
Child(Header):
<template>
<div class="child">
<p>Search:</p>
<form #submit.prevent="phrasePassed">
<input type="text" v-model="phrase" />
</form>
</div>
</template>
<script>
export default {
name: "search",
data() {
return {
phrase: ""
};
},
methods: {
phrasePassed() {
this.$emit("phrase-search", this.phrase);
}
}
};
</script>
passPhrase() brings the value from the child to the parent and then filteredPosts() find appropriate elements. I suspect that the form might be guilty of this issue but I do not know precisely how to get rid of it and still be able to pass the value to the parent.
Thanks
in the child you use submit event which called on enter. you should use #input on the input itself. and btw you didnt need even to declare pharse in the data because you didnt use it in the child. you just pass it up
you it like so
<template>
<div class="child">
<p>Search:</p>
<form>
<input type="text" #input="phrasePassed">
</form>
</div>
</template>
<script>
export default {
name: "search",
methods: {
phrasePassed(e) {
this.$emit("phrase-search", e.target.value);
}
}
};
</script>
I'm making a basic To Do app, where I have an input field and upon entering a task and pressing the "Enter" key the task appears in the list. Along with the task the TodoCard.vue component also generates a button, which I would like to use to delete the task.
I've added a #click="removeTodo" method to the button, but don't know where to place it, in the TodoCard component or in the App.vue file?
TodoCard component:
<template>
<div id="todo">
<h3>{{ todo.text }}</h3>
<button #click="removeTodo(todo)">Delete</button>
</div>
</template>
<script>
export default {
props: ['todo'],
methods: {
removeTodo: function (todo) {
this.todos.splice(this.todos.indexOf(todo), 1)
}
}
}
</script>
App.vue:
<template>
<div id="app">
<input class="new-todo"
placeholder="Enter a task and press enter."
v-model="newTodo"
#keyup.enter="addTodo">
<TodoCard v-for="(todo, key) in todos" :todo="todo" :key="key" />
</div>
</template>
<script>
import TodoCard from './components/TodoCard'
export default {
data () {
return {
todos: [],
newTodo: ''
}
},
components: {
TodoCard
},
methods: {
addTodo: function () {
// Store the input value in a variable
let inputValue = this.newTodo && this.newTodo.trim()
// Check to see if inputed value was entered
if (!inputValue) {
return
}
// Add the new task to the todos array
this.todos.push(
{
text: inputValue,
done: false
}
)
// Set input field to empty
this.newTodo = ''
}
}
}
</script>
Also is the code for deleting a task even correct?
You can send an event to your parent notifying the parent that the delete button is clicked in your child component.
You can check more of this in Vue's documentation.
And here's how your components should look like:
TodoCard.vue:
<template>
<div id="todo">
<h3>{{ todo.text }}</h3>
<button #click="removeTodo">Delete</button>
</div>
</template>
<script>
export default {
props: ['todo'],
methods: {
removeTodo: function (todo) {
this.$emit('remove')
}
}
}
</script>
App.vue:
<template>
<div id="app">
<input class="new-todo"
placeholder="Enter a task and press enter."
v-model="newTodo"
#keyup.enter="addTodo">
<TodoCard v-for="(todo, key) in todos" :todo="todo" :key="key" #remove="removeTodo(key)" />
</div>
</template>
<script>
import TodoCard from './components/TodoCard'
export default {
data () {
return {
todos: [],
newTodo: ''
}
},
components: {
TodoCard
},
methods: {
addTodo: function () {
// Store the input value in a variable
let inputValue = this.newTodo && this.newTodo.trim()
// Check to see if inputed value was entered
if (!inputValue) {
return
}
// Add the new task to the todos array
this.todos.push(
{
text: inputValue,
done: false
}
)
// Set input field to empty
this.newTodo = ''
}
},
removeTodo: function(key) {
this.todos.splice(key, 1);
}
}
</script>
