应用(父)
嗨,我有这些组件(儿童) TextComponent InfoErrorForm
当我按从父组件App提交时,不验证此表单。因此,我尝试在子组件(TextComponent)中注入$ validator进行验证,并提供但不显示message error。 如果可以帮助我验证inisde父组件的子代,则可以。 这是我的代码
AppComponent
<template>
<div>
<!-- Form validar numero max input -->
<form :class="{'was-validated': error_in_form_save_progress}" >
<card-shadow v-for="(texto,key) in sections_template.texts" :key="key" >
<texto-component
:orden="key+2"
v-model="sections_template.texts[key].content"
:tituloComponente="texto.title"
:inputName="texto.title" >
<template slot="section_show_error_validate_input">
<info-error-form
:listErrors='errors'
:name_field = "texto.title"
v-show = "error_in_form_save_progress" >
</info-error-form>
</template>
</texto-component>
</card-shadow>
</form>
<div class="row foot_button" >
<div class="offset-md-3 col-md-3">
<button class="btn" @click.prevent="save_progrees"> Guardar Cambios</button>
</div>
</div>
</div>
</template>
<script>
export default {
provide() {
return {
$validator: this.$validator,
};
},
data: function(){
return {
sections_template: {
texts:[
{
section_template_id: 1,
type: "texto",
title: "fundamentacion",
content: ""
},
{
section_template_id: 2,
type: "texto",
title: "sumilla",
content: ""
}
] },
error_in_form_save_progress: true
}
},
methods:{
save_progrees(){
this.$validator.validateAll().then((result) => {
if (result) {
this.error_in_form_save_progress = false;
alert("se guardaran cambios");
return
}
this.error_in_form_save_progress = true;
});
}
}
}
</script>

我用这段代码解决 在我的父组件中,我提供了,然后发送了$ validator
export default {
components:{
...
},
provide() {
return {
$validator: this.$validator,
}
},
在我的子组件中,我收到了
inject: ['$validator'],
在父组件中,我将此方法添加到发票验证中
methods:{
save_progrees(){
var validationArray = this.$children.map(function(child){
return child.$validator.validateAll();
});
window.Promise.all(validationArray).then((v) => {
v.some( element => { if ( element == false ) { throw "exists error in child component";} });
this.error_in_form_save_progress = false;
alert("datos guardados");
return
}).catch(() => {
this.show_message_error_validation();
});
},
show_message_error_validation(){
this.error_in_form_save_progress = true;
}
}
最后要显示组件信息错误中的错误,我使用此代码
<template>
<div class="row" v-if="errors.items">
<div class="col-md-12">
<template v-for="(e,key) in errors.items" >
<div class="text-danger" v-if="e.field ==name_field" :key="key"> {{e.msg}} </div>
</template>
</div>
</div>
</template>

请在您的子组件中注意this.errors,然后在手表中放入this。$ emit 如下所示:
watch: {
errors: function (value) {
this.$emit('TextComponent', value)
}
}
然后将其捕获到您的父组件上,在这里https://vuejs.org/v2/api/#vm-emit
