vue+element实现表格搜索

1、直接上代码

html(element)

html"><el-col :span="12">
    <-- 定义model="searchForm"作为form表单名 -->
    <el-form
             ref="searchForm"
             :model="searchForm"
             label-width="130px"
             label-position="right"
             @submit.native.prevent>
        <el-row :gutter="40">
            <el-col :span="10">
                <el-form-item
                      label="审批状态："
                      prop="q">
                    <-- 定义v-model="searchForm.checkstatus"作为select的value -->
                    <el-select
                               v-model="searchForm.checkstatus"
                               filterable
                               clearable
                               placeholder="请选择"
                               style="width:150px">
                        <-- 数据从CHECK_STATUS外部导入加载 -->
                        <el-option
                              v-for="item in CHECK_STATUS"
                              :key="item.value"
                              :label="item.label"
                              :value="item.value"/>
                    </el-select>
                </el-form-item>
            </el-col>
        </el-row>
    </el-form>
</el-col> 
<el-col
    :span="24"
    class="ibrain-search-panel__body__table">
    <el-table
              v-loading="listLoading"
              :stripe="true"
              :data="list"
              :fit="true"
              text-align="center"
              border>
        <el-table-column
              label="#"
              type="index"
              header-align="center"
              align="center"
              width="50"/>
    </el-table>
</el-col>

html" title=javascript>javascript

html" title=javascript>javascript">import { CHECK_STATUS } from '@/common/constants';
export default {
    data() {
        return {
            pageSize: 20,
            currentPage: 1,
            total: 0,
            listLoading: false,
            list: [],
            //接收值
            searchForm: {},
            //外部导入数据源加载select标签
            CHECK_STATUS
        };
    },
    //在html" title=vue>vue中，使用watch来响应数据的变化。
    watch: {
        //检测这个select的value是否有变化，如果有就重新执行getData()方法
        'searchForm.checkstatus'() {
            this.getData();
        }
    },
     created() {
        this.getData();
    },
    methods: {
        //默认加载的表格数据
        getData() {
            this.listLoading = true;
            this.$api.getOverWorkList({
                page: this.currentPage - 1,
                size: this.pageSize,
                sort: '',
                //这里动态拿表单里面select下拉框的值传入，以实现动态搜索
                checkstatus: this.searchForm.checkstatus
            }).then(data => {
                this.list = data.content;
                this.total = data.totalElements;
                this.listLoading = false;
            });
        }
    }
}

@/common/constants (用来作为select标签的数据源)

html" title=javascript>javascript">// 审批状态
const CHECK_STATUS = [{
    value: 'PENDING',
    label: '待审批'
}, {
    value: 'APPROVED',
    label: '已通过'
}, {
    value: 'REJECT',
    label: '已拒绝'
}, {
    value: 'CANCELLING',
    label: '撤销中'
}, {
    value: 'CANCELED',
    label: '已撤销'
}];
export {
    CHECK_STATUS
};
