I'm using Vue in my application and I would like to know how to submit a form but avoid redirection. According to the official Vue doc it can be achieved in the following way:
<!-- the submit event will no longer reload the page -->
<form v-on:submit.prevent="onSubmit"></form>
Here is my part of my form:
<form class="myForm" action="/page" method="post" @submit.prevent="onSubmit">
<input name="email" type="email" placeholder="e-mail" v-model="email">
<button @click="myFunction()">
It sorta works in the sense that the page is no longer redirected but I get an error saying that onSubmit
method is not defined. So What I don't understand is how I should define it. On the other hand I could just write @submit@prevent
but as far as I understand it completely prevents submission and that's not what I'm looking for.
Is there a proper way to do this without ajax, axios and that sort of technologies?
What I want is myFunction to execute and form to submit but I would want to avoid redirection.
prevent is shorthand for "on submit, do event. preventDefault() to stop the form from submitting".
The other way we can achieve preventing the default form submission behaviour is by attaching a submit event with the prevent modifier to the starting form tag in the template. This will prevent the page from reloading when the submit button is pressed as well.
To add an event listener to a component using the v-on directive with Vue. js, we should add the native modifier. to set the add the native modifier to @click and set it to buttonClickHandler . Then buttonClickHandler will run when we click on the router-link component.
$v is an object that calls vuelidate (at the time of writing the comment, supported in version Vue. js 2.0), which is intended to check every input, which is made in a non-html form.
onSubmit
should be a function within your methods
property on the vue instance. I.e
methods: {
onSubmit () {
// DO Something
}
}
Then as the docs say, using <form v-on:submit.prevent="onSubmit"></form>
is correct. I use this in my app.
See the example below. The message will change once the button is clicked without a page refresh.
var vm = new Vue({
el: '#app',
data () {
return {
test: 'BEFORE SUBMIT'
}
},
methods: {
onSubmit () {
this.test = 'AFTER SUBMIT'
}
}
});
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<div id="app">
{{test}}
<form v-on:submit.prevent="onSubmit">
<button>Submit!</button>
</form>
</div>
Just use @submit.prevent
(without any equal signs).
Then, define @click="doAction()"
on the button.
