vue+element+表格计算

需求描述:

表格有多行;

每一行都有长宽高;

当用户输入长宽高时,自动计算出体积;

长、宽、高、体积都需要存储到后端,都有对应字段;

也有用户不输入长宽高,直接输入体积的情况;

解决方法如下:

给长、宽、高增加@input

<el-table-column sortable label="LENGTH(cm)" width="150px" align="center" prop="length"
            :show-overflow-tooltip="true">
            <template slot-scope="scope">
              <el-input v-model="scope.row.length" @input="onInputChange(scope.row)"></el-input>
            </template>
          </el-table-column>
          <el-table-column sortable label="WIDTH(cm)" width="120px" align="center" prop="width"
            :show-overflow-tooltip="true">
            <template slot-scope="scope">
              <el-input v-model="scope.row.width" @input="onInputChange(scope.row)"></el-input>
            </template>
          </el-table-column>
          <el-table-column sortable label="HEIGHT(cm)" width="150px" align="center" prop="height"
            :show-overflow-tooltip="true">
            <template slot-scope="scope">
              <el-input v-model="scope.row.height" @input="onInputChange(scope.row)"></el-input>
            </template>
          </el-table-column>
          <el-table-column sortable label="VOLUME(M³)" width="150px" align="center" prop="volume"
            :show-overflow-tooltip="true">
            <template slot-scope="scope">
              <el-input v-model="scope.row.volume"></el-input>
            </template>
          </el-table-column>
      //
      onInputChange(row){
        console.log('row = ', row)
        if(row.height && row.length && row.width){
          row.volume = ((row.height * 0.01) * (row.length * 0.01) * (row.width * 0.01)).toFixed(3)
        }
      },
