封装一个Element-ui生成一个可行内编辑的表格(vue2项目)-编程知识

这个封装的是一个供整个项目使用的表格,可多次复用.放在一个全局使用的公共组件文件下.

大致功能介绍,封装自定义指令,点击获得焦点,显示输入框,失去焦点显示文本内容,类型是字典决定类型,图片可以显示图片名还是上传图片

子组件

<script>
export default {props: {//生成表头fields: {type: Array,default: () => [],},//数据tableData: {type: Array,default: () => [],},},data() {return {};},created() {},
// 自定义指令directives: {focus: {inserted: function (el) {el.querySelector("input").focus();},},},methods: {// 点击框 获取焦点 column列,row 行cellClick(column, row) {column.iseditor = true;row.isnameSelected = true;},//输入框失去焦点触发,此处用提示框提示修改blurEvent(column, row) {//  console.log(column, row);column.iseditor = false;row.isnameSelected = false;},},
};
</script>
<template><div><el-table :data="tableData" border style="width: 100%"><el-table-column:prop="field.prop":label="field.label":min-width="field.minWidth || 140"v-for="(field, index) in fields":key="index"show-overflow-tooltip><template slot-scope="scope"><div v-if="field.slot"><slot :name="field.slot" :row="scope.row" /></div><div v-else><div><el-inputv-if="field.iseditor && scope.row.isnameSelected"v-model="scope.row[field.prop]"@focus="cellClick(field, scope.row)"@blur="blurEvent(field, scope.row)"v-focus></el-input><p @click="cellClick(field, scope.row)" v-else>{{ scope.row[field.prop] || "--" }}</p></div></div></template></el-table-column></el-table></div>
</template>
<style scoped>
</style>
<style>
.el-tooltip__popper {max-width: 1000px;
}
.disabled .el-upload--picture-card {display: none;
}
.avatar-uploader .el-upload {border: 1px dashed #d9d9d9;border-radius: 6px;cursor: pointer;position: relative;overflow: hidden;
}
.avatar-uploader .el-upload:hover {border-color: #409eff;
}
.avatar-uploader-icon {font-size: 28px;color: #8c939d;width: 178px;height: 178px;line-height: 178px;text-align: center;
}
.avatar {width: 178px;height: 178px;display: block;
}
</style>

父组件

这里还有封装了一个文件上传的组件嵌套在表格中,算是拓展

<script>
import editComponents from "../../components/editComponents";
export default {components: { editComponents },data() {return {fields: [{prop: "industryCode",label: "产品",iseditor: false,},{prop: "id",label: "id",iseditor: false,},{prop: "paragraphType",label: "产品类型",iseditor: false,slot: "paragraphType",
//根据这个slot来决定是否要使用插槽,让父组件可以更好地使用数据,不用传来传去,下面是一样的},{prop: "paragraphImage",label: "产品图片",slot: "paragraphImage",iseditor: false,},{prop: "action",label: "操作",slot: "action",},],tableData: [{industryCode: "苹果",id: "15",paragraphType: "1",paragraphImage: "15.png",},{industryCode: "苹果",id: "16",paragraphType: "2",paragraphImage: "15.png",},{industryCode: "苹果",id: "17",paragraphType: "1",paragraphImage: "15.png",},],fileList: [], //文件总数fileList1: [], //详情文件总数dialogImageUrl: "",dialogVisible: false,disabled: false,};},computed: {//文件上传地址upLoadUrl() {//process.env.VUE_APP_BASE_API 检测当前环境来决定接口路径//测试环境 VUE_APP_BASE_API = '/stage-api'if (process.env.VUE_APP_BASE_API == "/stage-api") {return "接口地址"; //   例如:'/minio/upload'// 生产} else if (process.env.VUE_APP_BASE_API == "生产接口") {return "接口地址";} else {// 本地return "接口地址";}},},created() {this.getlist();},methods: {//获取数据getlist() {// 发请求获取数据写在这里this.tableData = this.tableData.map((item) => {return { ...item, isnameSelected: false };});},// 添加hAdd() {const productObj1 = {industryCode: "",id: "",paragraphType: "",paragraphImage: "",iseditor: false,uuId: Math.random(),};this.tableData.push(productObj1);},// 删除del(row) {this.tableData = this.tableData.filter((item) => item.uuId !== row.uuId || item.id !== row.id);},//图片上传===========================handleRemove(file) {console.log(file);console.log(this.$refs.upload);let uploadFiles = this.$refs.upload.uploadFiles;for (var i = 0; i < uploadFiles.length; i++) {if (uploadFiles[i]["url"] == file.url) {uploadFiles.splice(i, 1);}}},handlePictureCardPreview(file) {this.dialogImageUrl = file.url;this.dialogVisible = true;},handleDownload(file) {console.log(file);},// 文件上传成功-----------------async handleSuccess(response, row) {// 处理上传成功后的逻辑console.log("上传成功", response, row);this.fileName = response.data.fileName;row.paragraphImage = response.data.fileName;},handleError(err, file, fileList) {// 处理上传失败后的逻辑console.error("上传失败", err);},//  selectedLabel(selectedValue) {//   if (selectedValue === "1") {//     return "选择一";//   } else if (selectedValue === "2") {//     return "选择二";//   }// },async onSubmit() {// 删除不需要的属性this.tableData.forEach(function (obj) {if (obj.hasOwnProperty("iseditor")) {delete obj.iseditor;}if (obj.hasOwnProperty("uuId")) {delete obj.uuId;}if (obj.hasOwnProperty("isnameSelected")) {delete obj.isnameSelected;}});// 新增if (!this.industryCode) {//   新增请求写在这里console.log(res);if (res.message == "success") {this.$message({message: res.data,type: "success",duration: 1000,});} else {this.$message.error(res.data);}} else {// 修改请求写在这里console.log(res);if (res.message == "success") {this.$message({message: res.data,type: "success",duration: 1000,});this.goBack();} else {this.$message.error(res.data);}}},},
};
