业务模块「新增」时导入审批模板（固定 moduleKey，仅展示该类型下模板）
|
|
用法：
|
<ApprovalTemplateBindDialog
|
v-model:visible="visible"
|
module-key="regular"
|
@confirm="onTemplateBound"
|
/>
|
-->
|
<template>
|
<el-dialog
|
v-model="dialogVisible"
|
:title="dialogTitle"
|
:width="step === formStep ? 720 : 640"
|
append-to-body
|
destroy-on-close
|
class="approval-template-bind-dialog"
|
@closed="onClosed"

|
<template v-if="step === 1">
|
<ApprovalTemplatePicker
