二、JS

javascript 复制代码

<script setup>
// -------------------<<模块引入>>-------------------
import { ref, reactive, onMounted, nextTick } from "vue";
import { ElMessage } from "element-plus";
// -------------------<<变量声明>>-------------------
// 生成参数
const generateParams = reactive({
  type: 1, // 类型
  start: 1000000000, // 开始
  end: 2000000000, // 结束
  startTime: "2024-08-05 15:33:55", // 开始时间
  endTime: "2024-08-15 15:33:55", // 结束时间
  studentInfo: [
    // 任务区域
    {
      name: 123.1122331, // 姓名

      sex: 1200.1, // 性别
    },
    {
      name: 114.1122331, // 姓名

      sex: 1200.1, // 性别
    },

// form表单规则
const formRules = reactive({

  age: [{ required: true, message: "请输入年龄", trigger: "blur" }],
  sex: [{ required: true, message: "请输入性别", trigger: "blur" }],
});
// 获取form表单ref
const formRef = ref();
// 行列index
const rowIndex = ref(null);
const columnIndex = ref(null);
// 是否允许编辑
const isEdit = ref(true);

// -------------------<<函数定义>>-------------------
// 生成
const generate = (formEl) => {

    if (valid) {
      console.log(generateParams);
      TaskInfoModelRef.value.openWin();
    } else {
      console.log("error submit!");

      //当验证失败跳转到空白的所在区域
      nextTick(() => {
        let isError = document.getElementsByClassName("is-error");
        isError[0].scrollIntoView({
          // 滚动到指定节点
          // 值有start,center,end，nearest
          block: "center",
          // 值有auto、instant,smooth，缓动动画
          behavior: "smooth",
        });
      });

      return false;
    }
  });
};
// 表格单元格className回调方法
const cellClassName = ({ column, columnIndex }) => {
  column.index = columnIndex;
};
// 表格行className回调方法
const rowClassName = ({ row, rowIndex }) => {
  row.index = rowIndex;
};
// 表格单元格点击事件
const cellClick = (row, column) => {
  if (isEdit.value) {
    rowIndex.value = row.index;
    columnIndex.value = column.index;
  }
};
// input框失去焦点事件
const hideInput = (e) => {
  if (e.target.value) {
    rowIndex.value = null;
    columnIndex.value = null;
    isEdit.value = true;
  } else {
    isEdit.value = false;
  }
};
// 新增数据
const addRowData = () => {
  generateParams.studentInfo.push({
    name: "",
    age: "",
    sex: "",
  });
};
// 删除本行数据
const delRowData = (row) => {
  if (generateParams.studentInfo.length > 1) {
    generateParams.studentInfo.splice(row.index, 1);
  } else {
    ElMessage.warning("最少保留1条数据");
  }
};
// -------------------<<函数执行>>-------------------
onMounted(() => {});
