需求:Vue项目用到了el-table做的表格,需要前端根据指定条件去排序表格,后端没有进行排序。
最终效果图如下:
这个表格的数据tableData是前端用混入的写法发请求,后端返回的,但后端返回的数据不是按照“已选择到选择”这样的排列顺序返给前端,前端在处理排序是根据表格当前行与指定的id是否匹配来确定是不是"已选择"。这里在watch里监听后端返给的表单tableData,然后进行了深拷贝JSON.parse(JSON.stringify(newTable)),如果不深拷贝直接将排序后的表单数据赋值给tableData可能造成死循环。然后回显表单数据用到了新的变量tableDataShow。完整代码如下:
<template>
<div>
<el-input
v-model="queryParams.placeName"
style="margin:1rem 0"
placeholder="请输入场所名称"
@keyup.enter.native="getTableData(pager, queryParams)"
></el-input>
<el-table
:data="tableDataShow"
:header-cell-style="{
background: ' #eff3fb',
color: '#3c4353',
'font-weight': 600
}"
border
style="width: 100%;"
>
<el-table-column prop="placeName" label="场所名称" align="center">
</el-table-column>
<el-table-column prop="placeAddress" label="场所地址" align="center">
</el-table-column>
<el-table-column prop="placeTypeName" label="场所类型" align="center">
</el-table-column>
<el-table-column prop="placeTagName" label="标签" align="center">
</el-table-column>
<el-table-column fixed="right" label="操作" width="80" align="center">
<template slot-scope="scope">
<span
v-if="rowFormGet.docId && rowFormGet.docId == scope.row.id"
style="color:#aaaaaa"
>已选择</span

<span

@click="handleClick(scope.row)"
v-else

</el-table-column>
</el-table>
