el-dropdown的command方法添加自定义参数

代码

<div v-for="(item, index) in queryParams.changeParams" :key="index">
        <el-form-item prop="dataConditionSearch">
          <el-dropdown @command="handleCommand" style="margin-right: 3px;">
            <span class="el-dropdown-link" style="cursor: pointer;">
              {{queryParams.changeParams[index].dataCondition}}<i class="el-icon-arrow-down el-icon--right"></i>
            </span>
            <el-dropdown-menu slot="dropdown">
              <el-dropdown-item :command="beforeHandleCommand('大于', index)">大于</el-dropdown-item>
              <el-dropdown-item :command="beforeHandleCommand('小于', index)">小于</el-dropdown-item>
              <el-dropdown-item :command="beforeHandleCommand('等于', index)">等于</el-dropdown-item>
            </el-dropdown-menu>
          </el-dropdown>
          <el-input v-model="queryParams.changeParams[index].dataConditionSearch" placeholder="请输入" clearable style="width: 130px;" />
        </el-form-item>
        <el-form-item label-width="10px">
          <i class="el-icon-remove-outline" style="cursor: pointer;" @click.prevent="deleteChangeParams(item)" />
        </el-form-item>
      </div>

使用:command

    beforeHandleCommand(command, index) {
      return {
        'command': command,
        'index': index
      }
    },
    handleCommand(command) {
      let condition = command.command;
      let index = command.index;
      this.queryParams.changeParams[index].dataCondition = condition;
    },
