2.父组件使用子组件
2-1 引入封装好的子组件 及注册
import importCommon from "./importCommon.vue";
components: { importCommon }
2-2 使用
<importCommon
:titileDialog="dialogTitle"
:importDrawer="dialogImport"
:importDirection="dialogDirection"
:size="dialogSize"
:importDrawerWarapper="dialogWrapper"
:destroyImport="dialogDestory"
:isShowCloseImport="dialogIsShow"
@download="downloadHandle"
:importLoading="dialogLoading"
@sumbitHandle="sumbitHandle"
@importHandleClose="importHandleClose"
/>
data中写 // 封装导入模板
dialogTitle:'导入',
dialogLoading: false, // 提交的loading
dialogIsShow: true, // 导入弹框 是否显示关闭按钮
dialogWrapper: false, // 导入弹框 点击遮罩层是否可以关闭 Drawer
dialogSize: "50%", // 导入弹框大小
dialogDirection: "rtl", // 导入弹框 Drawer 打开的方向
dialogImport: false, // 导入弹框开关
dialogDestory: false, // 导入弹框控制是否在关闭Drawer 之后将子元素全部销毁
methods // 下载模板
downloadHandle() {
window.location.href = "/static/导入模板.xlsx";
},
// 弹出关闭
importHandleClose() {
this.dialogImport = false;
},
//提交方法
sumbitHandle(fd, dialogform, fileArray) {
console.log(fd, dialogform, fileArray, "fd, dialogform, fileArray");
//这里写请求接口
//再请求接口成功后 需要把上一次的文件清掉
fileArray.splice(0);
dialogform.maninFile.splice(0);
},
