vue + js 代码不生效？

Question

el-table 里的输入框实现递增输入，正常输入没有问题，当删掉其中一个值后，再输入符合条件的也不生效了，不知道是什么原因

Answer 1

也没搞懂你想要表达的需求，看你代码没有涉及到递增倍数只是纯提示。看是不是这样的，我按最简单办法搞。

        <template>
      <el-table :data="tableData" border style="width: 100%">
        <el-table-column prop="id" label="ID" width="180"> </el-table-column>
        <el-table-column prop="name" label="姓名"> </el-table-column>
        <el-table-column prop="amount1" sortable label="数值 1">
          <template slot-scope="scope">
            <el-input type="text" v-model="scope.row.price" />
          </template>
        </el-table-column>
        <el-table-column prop="amount2" sortable label="数值 2"> </el-table-column>
        <el-table-column prop="amount3" sortable label="数值 3"> </el-table-column>
        <el-table-column label="保存">
          <template slot-scope="scope">
            <el-button type="primary" size="mini" @click="handleSave(scope)"
              >保存</el-button
            >
          </template>
        </el-table-column>
      </el-table>
    </template>

    <script>
    export default {
      data() {
        return {
          tableData: [
            {
              id: "12987122",
              name: "王小虎",
              price: "1",
              amount2: "3.2",
              amount3: 10,
            },
            {
              id: "12987123",
              name: "王小虎",
              price: "2",
              amount2: "4.43",
              amount3: 12,
            },
            {
              id: "12987124",
              name: "王小虎",
              price: "3",
              amount2: "1.9",
              amount3: 9,
            },
            {
              id: "12987125",
              name: "王小虎",
              price: "4",
              amount2: "2.2",
              amount3: 17,
            },
            {
              id: "12987126",
              name: "王小虎",
              price: "5",
              amount2: "4.1",
              amount3: 15,
            },
          ],
        };
      },

      methods: {
        handleSave(e) {
          if (e.$index != 0) {
            let inputPrice = e.row.price;
            let row = e.$index - 1;
            if (inputPrice <= this.tableData[row].price) {
              this.$message.info("输入价格必须递增");
            } else {
              this.$message.info("保存成功！");
            }
          } else {
            this.$message.info("保存成功！");
          }
        },
      },
    };
    </script>
