Vue 解决通过this.$refs来获取DOM或者组件报错问题

this.$nextTick(() => { this.$refs.name... // DOM渲染完毕后能正常获取 }) - **使用setTimeout(fn, 0)**：虽然这不是最佳实践，但也可以达到类似的效果，通过将代码放入延时函数中，使其在当前事件...

详解Vue + Vuex 如何使用 vm.$nextTick

this.chartVisiable1 = !this.chartVisiable1; this.$nextTick(()=>{ var zongjineChart1 = echarts.init(document.getElementById("zongjineChart1"),'macarons');

这是一段 JavaScript 代码，它的作用是切换图表的可见性，并使用 ECharts 库初始化一个名为 zongjineChart1 的图表。其中，this.chartVisiable1 是一个变量，用于记录图表的可见性状态，!this.chartVisiable1 则...

data() { return { flag: false, flag1: false, flag2: false, flag3: false, flag4: false, flag5: false, }; }, components: { hot, seller, trend, Map, rank, stock, }, methods: { changetheme() { this.$store.commit("tabtheme"); }, full() { this.flag = true; this.$nextTick(() => { this.$refs.seller2.changesize(); }); }, full1() { this.flag1 = true; this.$nextTick(() => { this.$refs.trend2.screenAdapter(); }); }, full2() { this.flag2 = true; this.$nextTick(() => { this.$refs.rank2.screenAdapter(); }); }, full3() { this.flag3 = true; this.$nextTick(() => { this.$refs.hot2.screenAdapter(); }); }, full4() { this.flag4 = true; this.$nextTick(() => { this.$refs.stock2.screenAdapter(); }); }, full5() { this.flag5 = true; this.$nextTick(() => { this.$refs.map2.screenAdapter(); }); },优化后代码

this.$nextTick(() => { switch (index) { case 0: this.$refs.seller2.changesize(); break; case 1: this.$refs.trend2.screenAdapter(); break; case 2: this.$refs.rank2.screenAdapter(); ...

selectSysUserByDeptId(this.queryParams).then(jtem => { this.tableData = jtem.data; if(this.form.priBelongDocter != null){ let array = this.form.priBelongDocter.split(','); this.$nextTick(() => { this.tableData.forEach(row => { array.forEach(ztem => { if(row.userId.toString() == ztem){this.$refs.multipleTable.toggleRowSelection(row,true);} }); }); }); } });

这是一段 JavaScript 代码，它使用了 Promise 和箭头函数等语法，主要是用来查询系统用户并将结果展示在表格中。同时，它还会根据表单中的 priBelongDocter 字段来选中表格中对应的行。

<div class="fullseller" :... this.$nextTick(() => { this.$refs.seller2.changesize(); }); }, full5() { this.flag5 = !this.flag5; this.$nextTick(() => { this.$refs.map2.screenAdapter(); }); }, }

this.$nextTick(() => { this.$refs.uploadFile.$children[0].$refs.input.webkitdirectory = true; })

This code uses the Vue.js framework to access a component called "uploadFile" and set a property on its child element's "input" object. Specifically, it sets the "webkitdirectory" property to true, ...

<trend class="trend" ref="trend2"> </trend> <seller class="seller" ref="seller2"></seller> data() { return { flag1: false, flag2: false, flag3: false, flag4: false, flag5: false, flag6:false, } }, computed:{ ...mapState(["theme"]) }, methods:{ changeTheme(){ this.$store.commit("tabTheme") }, full1(){ this.flag1= true; this.$nextTick(() => { this.$refs.rank2.screenAdapter(); }); }, full2() { this.flag2 = true; this.$nextTick(() => { this.$refs.rank2.screenAdapter(); }); }, full3() { this.flag3 = true; this.$nextTick(() => { this.$refs.hot2.screenAdapter(); }); }, full4() { this.flag4 = true; this.$nextTick(() => { this.$refs.stock2.screenAdapter(); }); }, full5() { this.flag5 = true; this.$nextTick(() => { this.$refs.map2.screenAdapter(); }); }, full6() { this.flag6 = true; this.$nextTick(() => { this.$refs.map2.screenAdapter(); }); },的优化

this.$nextTick(() => { this.$refs.stock2.screenAdapter(); }); }, smallscreen4() { this.flag4 = false; this.$nextTick(() => { this.$refs.stock2.screenAdapter(); }); }, }, }; </script>

优化这段代码if (this.mode === 'create') { this.uuid = uuid.generate() this.uploadId = this.uuid } else { this.uuid = this.id this.uploadId = this.uuid value.time = value.time ? moment(value.time) : null if (!this.resubmitMode) { this.$nextTick(() => { this.$refs.upFile.loadFiles() }) } else { this.uploadId = uuid.generate() } }

this.$nextTick(() => { this.$refs.upFile.loadFiles(); }); } else { this.uploadId = uuid.generate(); } } 可以看到，我将 this.uuid 和 this.uploadId 的赋值放到了一起，并且使用了统一的赋值...

getDetailById(id){ postDetail(id).then(res => { this.formData = res.data this.getFlowGroupInfoById(this.formData.flowGroupId) this.setCommissionData() this.setOutputData() this.setReleaseData() console.log(this.$refs.tree,this.formData.userIdListDeliver) console.log(this.$refs.tree.filter) this.$nextTick(()=>{ this.$refs.tree.filter(1) }) }) },

1. 确保$refs.tree已正确地引用了您期望的组件或元素，可以通过在mounted或updated生命周期钩子中使用console.log(this.$refs.tree)来验证。 2. 确保您的组件或元素上具有名为filter的方法。您可以通过在...

<el-button class="buttonInfo" size="small" @click="updataMethod(scope.$index,scope.row)">编辑</el-button>updataMethod(index, rowData) { this.dialogEdittVisible = true this.$nextTick(() => { this.dialogType = 'editProjectOne' this.formEditTitle = '编辑' this.formEdit = Object.assign({}, rowData) this.getMbsj() }) }, getTarget() { if (this.formList.indexName == null || this.formList.indexName == '') { this.$message('请选择分项') return false } if (this.itemize == null || this.itemize == '') { this.$message('请选择总量') return false } this.$ajax({ url: '/lims/projectLib/project_item', method: 'post', data: { name: this.formList.indexName, tableData: this.selectedData, }, }).then(res => { if (res.data.code === 200) { this.$message({ message: '添加成功', center: true, type: 'success', }) this.dialogEdittVisible = false this.getList() } else { this.$message({ message: res.data.msg, center: true, type: 'error', }) this.dialogEdittVisible = false } }) },点击编辑按钮时如何显示编辑之前的数据

根据你提供的代码，可以看出编辑按钮点击后会触发 ... <el-input v-model="formEdit.name"></el-input> </el-form-item> 这里假设当前行数据对象中有一个名为 name 的属性。你可以根据实际情况调整代码。

watch: { dataList(val) { let arr = JSON.parse(JSON.stringify(val)) arr.map((ele, index) => { this.saveRows.map((item) => { if (item.containerId && ele.containerId) { let arr1 = ele.containerId, arr2 = item.containerId let ifHas = arr1.every((a) => { return arr2.some((b) => a === b) }) //如果是在这个里面，那么就是true console.log(ifHas) //true if (ifHas) { this.$nextTick(() => { this.$refs.table.toggleRowSelection(this.dataList[index], true) }) } } }) }) if (this.cancelRows.length > 0) { arr.map((ele, index) => { this.cancelRows.map((item) => { if (item.containerId && ele.containerId) { let arr1 = ele.containerId, arr2 = item.containerId let ifHas = arr1.every((a) => { return arr2.some((b) => a === b) }) if (ifHas) { this.$nextTick(() => { this.$refs.table.toggleRowSelection( this.dataList[index], false, ) }) } } }) }) } },

如果当前元素和this.saveRows数组中的元素都有containerId属性，那么它会比较两个数组的containerId属性是否完全相同。如果完全相同，它会将当前元素添加到Vue组件中的一个表格组件的选中行中。接着，它检查...

this.$nextTick(_=>{ this.$refs.saveTagInput.$refs.input.focus() })帮我解析一下这行代码

具体来说，this.$nextTick会将回调函数推入到一个异步队列中，待DOM更新循环结束后再执行这个回调函数。回调函数中的代码是通过this.$refs.saveTagInput获取到保存标签输入框的Vue组件实例，并通过$refs....

handleEdit(row) { this.form = JSON.parse(JSON.stringify(row)) this.dialogFormVisible = true this.$nextTick(() => { if(this.$refs.img) { this.$refs.img.clearFiles(); } if(this.$refs.file) { this.$refs.file.clearFiles(); } }) 添加注释

第二部分：this.$nextTick(() => { ... }) 在下一次 DOM 更新后执行回调函数。这里使用了箭头函数，箭头函数没有自己的 this，所以可以访问到外层的 this 对象。回调函数的作用是清空表单中的图片和文件上传组件，...

ceshiyongliCrossAddOrUpdateHandler(row,type,crossOptAudit,statusColumnName,tips,statusColumnValue){ this.showFlag = false; this.addOrUpdateFlag = false; this.ceshiyongliCrossAddOrUpdateFlag = true; this.$storage.set('crossObj',row); this.$storage.set('crossTable','gongnengxuqiu'); this.$storage.set('statusColumnName',statusColumnName); this.$storage.set('statusColumnValue',statusColumnValue); this.$storage.set('tips',tips); if(statusColumnName!=''&&!statusColumnName.startsWith("[")) { var obj = this.$storage.getObj('crossObj'); for (var o in obj){ if(o==statusColumnName && obj[o]==statusColumnValue){ this.$message({ message: tips, type: "success", duration: 1500, onClose: () => { this.getDataList(); } }); this.showFlag = true; this.ceshiyongliCrossAddOrUpdateFlag = false; return; } } } this.$nextTick(() => { this.$refs.ceshiyongliCrossaddOrUpdate.init(row.id,type); }); },

如果状态列名为空或为数组，或者行数据中状态列名对应的属性值不等于状态列值，则会通过$nextTick方法调用子组件的init方法进行添加或更新操作。该函数的具体实现还需要结合其他代码和组件进行分析。

解释一下//获取数据列表 getDataList() { this.dataListLoading = true; let params = { page: this.pageIndex, limit: this.pageSize, sort: 'id', order: 'desc', } this.$http({ url: "jiaocaixinxi/page", method: "get", params: params }).then(({ data }) => { if (data && data.code === 0) { this.dataList = data.data.list; this.totalPage = data.data.total; } else { this.dataList = []; this.totalPage = 0; } this.dataListLoading = false; }); } // 添加/修改 addOrUpdateHandler(id,type) { this.showFlag = false; this.addOrUpdateFlag = true; this.crossAddOrUpdateFlag = false; if(type!='info'){ type = 'else'; } this.$nextTick(() => { this.$refs.addOrUpdate.init(id,type); }); }是什么意思

这是一个Vue组件中的两个函数。 getDataList() 函数用于获取数据列表。在该函数中，首先设置 ...使用 $nextTick 方法等待界面渲染完成后，调用子组件 addOrUpdate 的 init 方法，初始化添加或修改数据的操作。
