# 事件监听
通过配置项on,emit可监听组件内抛出的事件, 例如监听input组件的change事件,事件名称参考Input
# 通过配置项on监听事件
<template>
<form-create :rule="rule" v-model="fApi" :option="options"/>
</template>
<script>
export default {
data(){
return {
fApi:{},
options:{
onSubmit:(formData)=>{
alert(JSON.stringify(formData));
}
},
rule:[
{
type:'input',
field:'event',
title:'change 事件',
on:{
change:()=>{
alert(`change!![${this.fApi.getValue('event')}]`);
}
}
}
]
}
}
}
</script>
# 通过配置项emit监听事件
只支持在组件模式下使用
事件名称为${field}-${eventName}
<template>
<form-create :rule="rule" v-model="fApi" :option="options" @input-field-change="change" @input-field2-blur="blur"/>
</template>
<script>
export default {
data(){
return {
fApi:{},
options:{
onSubmit:(formData)=>{
alert(JSON.stringify(formData));
}
},
rule:[
{
type:'input',
field:'inputField',
title:'change 事件',
emit:['change']
},
{
type:'input',
field:'inputField2',
title:'blur 事件',
emit:['blur']
}
]
}
},
methods:{
change(){
alert(`change!![${this.fApi.getValue('inputField')}]`);
},
blur(){
alert('blur!');
}
}
}
</script>
# 通过配置项emitPrefix自定义事件前缀
事件名称为${emitPrefix}-${eventName}
<template>
<form-create :rule="rule" v-model="fApi" :option="options" @prefix1-change="change" @prefix2-blur="blur"/>
</template>
<script>
export default {
data(){
return {
fApi:{},
options:{
onSubmit:(formData)=>{
alert(JSON.stringify(formData));
}
},
rule:[
{
type:'input',
field:'inputField',
title:'change 事件',
emit:['change', 'blur'],
emitPrefix:'prefix1'
},
{
type:'input',
field:'inputField2',
title:'blur 事件',
emit:['blur'],
emitPrefix:'prefix2'
}
]
}
},
methods:{
change(){
alert(`change!![${this.fApi.getValue('inputField')}]`);
},
blur(){
alert('blur!');
}
}
}
</script>
# 通过on方法监听事件
<template>
<form-create :rule="rule" v-model="fApi" :option="options"/>
</template>
<script>
export default {
data(){
return {
fApi:{},
options:{
onSubmit:(formData)=>{
alert(JSON.stringify(formData));
}
},
rule:[
{
type:'input',
field:'inputField',
title:'change 事件',
emit:['change', 'blur'],
emitPrefix:'prefix1'
},
{
type:'input',
field:'inputField2',
title:'blur 事件',
emit:['blur'],
}
]
}
},
methods:{
change(){
alert(`change!![${this.fApi.getValue('inputField')}]`);
},
blur(){
alert('blur!');
}
},
mounted(){
this.$nextTick(()=>{
this.fApi.on('prefix1-change',this.change);
this.fApi.on('input-field2-blur',this.blur);
})
}
}
</script>
# 向事件中注入$f和自定义参数
支持多种方式开启事件注入
<template>
<form-create :rule="rule" v-model="fApi" :option="options" @prefix1-change="change"/>
</template>
<script>
export default {
data(){
return {
fApi:{},
options:{
onSubmit:(formData)=>{
alert(JSON.stringify(formData));
}
},
rule:[
{
type:'input',
field:'inputField',
title:'change 事件',
emit: [{
name: 'change',
inject: ['自定义参数,数据类型不限']
}],
emitPrefix:'prefix1',
},
{
type:'input',
field:'inputField2',
title:'blur 事件',
inject:true,
on:{
blur: this.blur
}
}
]
}
},
methods:{
change(inject){
alert(`change: ${inject.inject}[${inject.$f.getValue('inputField')}]`);
},
blur(inject){
alert(`blur: ${inject.self.title}`);
}
}
}
</script>
inject 参数的数据结构
{
$f:Object,//api
rule:Array,//生成规则
self:Object,//当前生成规则
option:Object,//全局配置
inject:Any,//自定义注入的参数
}
参数注入也可以通过全局配置项injectEvent:true开启
