一、element的el-form和el-table嵌套使用
二、应用实例
一、element的el-form和el-table嵌套使用要点:
:model="addJsonForm"
给表单绑定数据,addJsonForm
是传入表单的数据对象
注意表单数据对象 addJsonForm
的定义:属性 params
(可按需求命名)为表单内嵌套的表格的显示数据,数组类型; 属性 addJsonRules
,为表单绑定的验证规则。
el-table
: 采用自定义列模板,可自定义表头, el-form
: 表单项绑定对应的字段名和校验规则
:prop="'params.' + scope.$index + '.name'"
绑定传入Form 组件的 model 中对应的字段 name
:rules="addJsonForm.addJsonRules.name"
绑定表单验证规则
<template>
<div>
<el-form
:model="addJsonForm"
ref="addJsonForm"
:rules="addJsonForm.addJsonRules"
:inline="true"
label-width="108px"
>
<el-table :data="addJsonForm.params" style="width: 100%" border>
<el-table-column type="selection" width="55" align="center">
</el-table-column>
<el-table-column align="center">
<template slot="header" slot-scope="scope">
<span style="color:#2d65dc;">成员名称</span>
<i style="color:#F56C6C;">*</i>
</template>
<template slot-scope="scope">
<el-form-item
:prop="'params.' + scope.$index + '.name'"
:rules="addJsonForm.addJsonRules.name"
>
<el-input
type="text"
v-model="scope.row.name"
autocomplete="off"
></el-input>
</el-form-item>
</template>
</el-table-column>
<el-table-column align="center">
<template slot="header" slot-scope="scope">
<span style="color:#2d65dc;">成员值</span>
<i style="color:#F56C6C;">*</i>
</template>
<template slot-scope="scope">
<el-form-item
:prop="'params.' + scope.$index + '.value'"
:rules="addJsonForm.addJsonRules.value"
>
<el-input
type="text"
v-model="scope.row.value"
autocomplete="off"
></el-input>
</el-form-item>
</template>
</el-table-column>
</el-table>
</el-form>
</div>
</template>
<script>
export default {
data() {
return {
addJsonForm: {
params: [
{
name: "",
value: ""
}
],
addJsonRules: {
name: [
{ required: true, message: "请输入成员名称", trigger: "blur" }
],
value: [
{ required: true, message: "成员值不能为空", trigger: "blur" }
]
}
}
};
}
};
</script>
二、应用实例
点击添加的时候,动态增加表格的行数,点击删除的时候,删除表格的行数据。

: 因评论区问到后续如何用 Form 表单的 resetFields 方法,这里就新加一个重置功能。
