最近遇到一个需要超级写超级多字段的表单，初略计算大概四十来个吧字段吧，/(ㄒoㄒ)/~~，这也太麻烦了，想了想能不能简单封装一下，找到了个巨人，嗯哼，就踩一下吧
参考文章： Vue3.0 根据JSON对象生成指定form表单 上面文章是vue3的，逻辑都一样。以下是vue2 我的写法
1.定义 formTemplate.vue
<template>
<el-col v-if="isCol" :span="colSpan">
<div v-if="isForm">
<el-form-item :prop="prop" :label="label">
<component
:is="isCom"
:config="config"
v-model="templateValue"
@change="change"
/>
</el-form-item>
</div>
<div v-else>
<component
:is="isCom"
:config="config"
v-model="templateValue"
@change="change"
/>
</div>
</el-col>
<div v-else>
<div v-if="isForm">
<el-form-item :prop="prop" :label="label">
<component
:is="isCom"
:config="config"
v-model="templateValue"
@change="change"
/>
</el-form-item>
</div>
<div v-else>
<component
:is="isCom"
:config="config"
v-model="templateValue"
@change="change"
/>
</div>
</div>
</template>
<script>
import formInput from "./formInput";
import formSelect from "./formSelect"
/**
* @author BlackKey
* @params value 双向绑定值
* @params colSpan 布局占位
* @params isCol 是否启用布局
* @params isForm 是否用form包裹
* @params label 标题
* @params prop model的键名
* @params isCom 需要的生成的组件
* @params config 组件对应的配置文件
* @desc form表单默认格式
*/
export default {
components: {
formInput,
formSelect
},
model: {
prop: "value",
event: "change",
},
props: {
colSpan: {
type: Number,
default: 6,
},
isCol: {
type: Boolean,
default: true,
},
isForm: {
type: Boolean,
default: true,
},
label: {
type: String,
default: "",
},
prop: {
type: String,
default: "",
},
isCom: {
type: String,
default: "formInput",
},
value: {
type: [String, Number, Object, Array],
default: "",
},
config: {
type: Object,
default: () => ({}),
},
},
methods: {
change(data) {
this.$emit("change", data);
}
},
computed: {
templateValue: {
get() {
return this.value;
},
set(val) {
this.$emit("change", val);
},
}
},
};
</script>
<style lang="less" scoped></style>2. 输入框组件 formInput.vue
<template>
<el-input
v-model="inputValue"
:placeholder="defaultConfig.placeholder"
:clearable="defaultConfig.clearable"
:disabled="defaultConfig.disabled"
:type="defaultConfig.type"
:maxlength="defaultConfig.maxlength"
:autosize="defaultConfig.autosize"
/>
</template>
<script>
/**
* @author BlackKey
* @params value 双向绑定值
* @params placeholder 输入框占位符文本
* @params type 输入框类型
* @params maxlength 最大长度
* @params disabled 是否禁用
* @params size 输入框尺寸
* @params autosize textarea 高度是否自适应，仅 type 为 'textarea' 时生效。
* @params clearable 是否展示清空按钮
* @desc 输入框
*/
export default {
props: {
config: {
type: Object,
default: () => ({ }),
},
value: {
type: [String, Number, Object, Array],
default: "",
},
},
data(){
return {
inputValue: '',
defaultConfig: {
placeholder: "",
type: "text",
maxlength: "",
disabled: false,
size: "",
autosize: false,
clearable: true,
}
}
},
mounted(){
this.inputValue = this.value
this.defaultConfig = {...this.defaultConfig, ...this.config}
},
watch: {
inputValue: {
immediate: true,
handler(newVal, oldVal) {
this.$emit("change", newVal);
},
},
},
}
</script>3. 下拉选择框 formSelect.vue
<template>
<el-select
v-model="selectValue"
:clearable="defaultConfig.clearable"
:placeholder="defaultConfig.placeholder"
:disabled="defaultConfig.disabled"
:size="defaultConfig.size"
>
<el-option
v-for="item in defaultConfig.options"
:key="item[defaultConfig.labelKey]"
:label="item[defaultConfig.labelKey]"
:value="item[defaultConfig.valueKey]"
></el-option>
</el-select>
</template>
<script>
/**
* @author BlackKey
* @params modelValue 双向绑定值
* @params placeholder 输入框占位符文本
* @params disabled 是否禁用
* @params size 输入框尺寸
* @params clearable 是否展示清空按钮
* @params options 下拉框的值
* @params dataType 预先设定好的枚举
* @params labelKey 下拉框labelKey
* @params valueKey 下拉框valueKey
* @desc 下拉框
*/
export default {
props: {
config: {
type: Object,
default: () => ({}),
},
value: {
type: [String, Number, Object, Array],
default: "",
},
},
data() {
return {
selectValue: "",
source: [
{
label: "男",
value: "man",
},
{
label: "女",
value: "woman",
},
],
defaultConfig: {
placeholder: "",
disabled: false,
size: "",
clearable: true,
options: [],
dataType: "",
labelKey: "label",
valueKey: "value",
}
};
},
mounted() {
this.selectValue = this.value
this.defaultConfig = {...this.defaultConfig, ...this.config}
// Object.keys(this.config).forEach(key=>{this.defaultConfig[key]=this.config[key]})
},
watch: {
selectValue: function (newVal, oldVal) {
this.$emit("change", newVal);
}
}
};
