1.Dialog中套用distpicker.js(elementui dialog提前渲染小技巧),若要初始化值的话,不可使用data-toggle="distpicker"固定写法
<el-dialog @open="handleCompanyInfoFormOpen" ref="CompanyInfoForm" :visible.sync="showCompanyInfoForm" ></el-dialog>
mounted(){
this.$refs.CompanyInfoForm.rendered = true;
},
handleCompanyInfoFormOpen(){
$('#distpicker').distpicker({
province: remoteGlobal.userInfo.Company.AddrProvince,
city: remoteGlobal.userInfo.Company.AddrCity,
district: remoteGlobal.userInfo.Company.AddrDistrict,
});
}(20220526补充)
使用v-model绑定会导致distpicker因初始化值失败,导致市和区的数据变为undefined
所以正确的初始化方法是给每个distpickerd的select组件增加id,使用原生方法来初始化
这distpicker是真坑啊,以上的动态初始化所选值不正确(或者说能在某种情况下成功但是没有下面的例子完善),下面给出一版正确的例子
<div id="consigner_change_distpicker">
<select class="form_distpicker_select" v-model='ChangeConsignerForm.AddrProvince' id="consignerChangeAddrProvince" data-province="选择省"></select>
<select class="form_distpicker_select" v-model='ChangeConsignerForm.AddrCity' id="consignerChangeAddrCity" data-city="选择市"></select>
<select class="form_distpicker_select" v-model='ChangeConsignerForm.AddrDistrict' id="consignerChangeAddrDistrict" data-district="选择区"></select>
<el-input v-model="ChangeConsignerForm.Address" placeholder="地址补充" style="width: 142px"></el-input>
</div>
//初始化change表单的控件,并初始化distpicker控件,后续点开dialog不会出现无法点击的bug了
handleChangeConsignerFormOpen(){
let tmpConsignerData = JSON.parse(JSON.stringify(vue_consignerinfo.ChangeConsignerForm));
$('#consigner_change_distpicker').distpicker();
$("#consignerChangeAddrProvince").val(tmpConsignerData.AddrProvince);
$("#consignerChangeAddrProvince").trigger("change");
$("#consignerChangeAddrCity").val(tmpConsignerData.AddrCity);
$("#consignerChangeAddrCity").trigger("change");
$("#consignerChangeAddrDistrict").val( tmpConsignerData.AddrDistrict);
},2.表格中通过slot-scope来对某一列数据做合并(自定义数据展示效果)
<el-table-column prop="AddrProvince+AddrCity+AddrDistrict" label="所属区域" align="center">
<template slot-scope="scope">
<div>{{ (scope.row.AddrProvince+scope.row.AddrCity+scope.row.AddrDistrict) }}</div>
</template>
</el-table-column>3.vue中this.$set的用法
当你发现你给对象加了一个属性，在控制台能打印出来，但是却没有更新到视图上时，也许这个时候就需要用到this.$set（）这个方法了，简单来说this.$set的功能就是解决这个问题的啦。
https://www.jianshu.com/p/6f28f5abee08
handleMouseEnter(data){
this.$set(data, 'show', true);
},
handleMouseLeave(data){
this.$set(data, 'show', false);
},4. elementUI tree中增加功能性按钮+label过长时显示...(css处理)
.addrTree .custom-tree-node {
flex: 1;
display: flex;
align-items: center;
justify-content: space-between;
font-size: 12px;
padding-right: 4px;
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
width: 100%;
}
.addrTree .em-tree-text{
display: inline-block;
overflow: hidden;
white-space: nowrap;
width:90%;
text-overflow: ellipsis;
}
<div class="addrTree">
<el-tree ref="addrTree" :data="addrData" node-key="id" default-expand-all highlight-current>
<span class="custom-tree-node" slot-scope="{ node, data }">
<i class="el-icon-circle-close delIcon"></i>
<el-tooltip effect="light" :content="node.label" placement="top" open-delay="500" node-key="id">
<span class="em-tree-text" style="color: #e44646;">{{ getAddrName(node.label)[0] }}
<span style="color: #6f7374;">{{ getAddrName(node.label)[1] }} </span>
</span>
</el-tooltip>
<el-popconfirm v-if="node.level==1" title="确定删除发货地址吗？" @confirm="delSendAddrNode(node, data)">
<i slot="reference" class="el-icon-circle-close delIcon"></i>
</el-popconfirm>
<el-popconfirm v-if="node.level==2" title="确定删除收货地址吗？" @confirm="delSaveAddrNode(node, data)">
<i slot="reference" class="el-icon-circle-close delIcon"></i>
</el-popconfirm>
</span>
</el-tree>
</div>5. js object对象,元素值相同合并
参考链接https://www.csdn.net/tags/OtTaQg3sNzY2OTEtYmxvZwO0O0OO0O0O.html
for(const key in localdata){
if(vue_history.localDataObj.hasOwnProperty(key)){
vue_history.localDataObj[key] += recv['localdata'][key];
}
else{
vue_history.localDataObj[key] = recv['localdata'][key];
}
}6. 为什么elementui中 v-loading失效
检查下ajax中 async 是否为false
当使用false时,页面直接卡住等待,直到完成(非异步方式)loading自然也就不生效了!!!!!!
这次没有代码哦!被自己蠢死了!7. elementui使用树形结构时自定义内部显示内容
使用slot-scope即可,有机会要学一下slot-scope的详细用法,自己想办法写一次
<el-tree ref="cargoDataTree" :data="allCargoDataTree" show-checkbox node-key="id" >
<span class="custom-tree-node" slot-scope="{ node, data }" style="width:100%;" >
<span>{{ node.label }}</span>
</span>
</el-tree>8. elementui-Pagination 分页组件修改位置固定
不知道为啥,外部套上一个width会导致定位偏移
<div style="position:absolute;height:50px;top:545px;right:0px;">
<el-pagination layout="prev, pager, next" :current-page="currentPage" :page-size="pageSize" @current-change="handleCurrentChange" :page-count="pageCount" >
</el-pagination>
</div>9. elementui form 动态增加表单
注意,若需要用rule校验,:key="item.port" 必须设置成item的一个存在的键!!!!并保证prop参数唯一
:key="item.key"
:prop="'listPorts.' + index + '.value'"
:rules="{ required: true, message: 'Please input server port', trigger: 'blur'}">
<div class="cargo-label-form">
<el-form :model="CargoForm" ref="CargoForm" label-width="80px" inline="true" v-for="(item, index) in CargoForm.ConsignerPrice" >
<el-form-item
:prop="'ConsignerPrice.' + index + '.ConsignerID'"
label="客户"
:key="item.index"
:rules="{
required: true, message: '客户不能为空', trigger: 'blur'
}"
>
<el-select filterable v-model="item.ConsignerID" placeholder="请选择客户" style="width: 120px;" size="mini">
<el-option
v-for="id in ConsignerList"
:key="id.ConsignerID"
:label="id.ConsignerNameA"
:value="id.ConsignerID">
</el-option>
</el-select>
</el-form-item>
<el-form-item
:prop="'ConsignerPrice.' + index + '.Price'"
label="计费件数"
:key="item.index"
:rules="{
required: true, message: '折算计费件数不能为空', trigger: 'blur'
}"
>
<el-input v-model="item.Price" style="width: 50px;" size="mini"></el-input>
<el-button size="mini" @click.prevent="removeLine(index)" >删除</el-button>
<el-button size="mini" @click="addLine" v-if="CargoForm.ConsignerPrice[index+1] == undefined">新增</el-button>
</el-form-item>
</el-form>
</div>
removeLine(index){
if(vue_cargoadd.CargoForm.ConsignerPrice.length ==1){
return;
}
vue_cargoadd.CargoForm.ConsignerPrice.splice(index,1);
},
addLine(){
vue_cargoadd.CargoForm.ConsignerPrice.push(
{
ConsignerID:'',
Price:'',
});
},10. elementui table 动态可编辑表格
<el-table ref="tmpCargoTable" v-loading="tableloading" style="border: #a6a6a6 1px solid;"
:row-style="rowstyle"
:data="cargoTableData"
height="100%" border
size="mini"
empty-text="暂无数据"
highlight-current-row
@row-click="handleRowClick"
:cell-style="cellstyle"
:header-row-style="headerrowstyle"
:header-cell-style="headercellstyle"
@cell-click="carogTableCellClick">
<el-table-column prop="CargoName" label="货物名称" align="center">
</el-table-column>
<el-table-column prop="CargoModel" label="规格型号" align="center">
</el-table-column>
<el-table-column prop="CargoUnit" label="单位" align="center">
</el-table-column>
<el-table-column prop="CargoVolume" label="单位体积(M³)" width="120" align="center">
</el-table-column>
<el-table-column prop="CargoWeight" label="单位重量(KG)" width="120" align="center">
</el-table-column>
<el-table-column prop="CargoCount" label="数量" width="120" align="center">
<template slot-scope="scope">
<el-input
v-if="scope.row.editable"
v-model="scope.row.CargoCount"
style="width: 100%;height:100%"
size="mini"
ref="CargoCountInput"
@blur="handleEditCargoNum(scope)"
/>
<span v-else>{{ scope.row.CargoCount }}</span>
</template>
</el-table-column>
</el-table>
carogTableCellClick(row, column, cell, event){
if(column.label == "数量"){
this.$set(row, 'editable', true);
this.$nextTick(() => {
this.$refs.CargoCountInput.focus()//显示文本框并获取焦点
})
}
},
//失去焦点后固化数据
handleEditCargoNum(scope){
// console.log(scope.row);
this.$set(scope.row, 'editable', false);
},11. elementui 修改绑定内置方法，加入新的参数
// 例如修改checkbox触发的事件，调整入参
@change="setLimitPublic"
@change="(val)=>{setLimitPublic(val, 2)}"
···
##12. elementui select框 代码选择并自动触发change事件vue_tranroad.$refs.DeliverTypeChoose.value = "0";//也可以vue设置绑定值吧
vue_tranroad.$refs.DeliverTypeChoose.$emit('change');
##11. vue3 elementui menu 使用route.push 后 页面跳转但是menu 高亮没变<el-menu :default-active="router.currentRoute.value.path" :router="true" mode="horizontal"
background-color="var(--bg-head-bar)"
text-color="#fff"
active-text-color="#ff862d">import { useRouter } from 'vue-router'
const router = useRouter()
