vue中数组检测重复性的两个方法

Posted 2022-06-12 front-endgraph

检查数组重复（一）
let inputValue = this.positionGroupInput[groupId].inputValue;
if (inputValue)
for (let positionGroup of this.lists)
if (positionGroup.id === groupId)
// 检查重复性
let isExist = false;
for (let position of positionGroup.positions)
if (position.name === inputValue)
this.$message.error("职位名称不能重复");
isExist = true;


if (!isExist)
const newPosition = groupId: groupId, id: this.generateId(), name: inputValue;
positionGroup.positions.splice(positionGroup.positions.length, 0, newPosition);
this.$message.success("添加职位成功")

检查数组重复（二）
function displayDate()
var arr = [ d: ‘2015-10-12‘,C:‘Apple‘, d: ‘2015-10-12‘,C:‘Apple‘, d: ‘2015-10-13‘,C :‘Apple‘ ];
var find = false;
for (var i = 0; i < arr.length; i++)
for (var j = i + 1; j < arr.length; j++)
if (arr[i].d == arr[j].d && arr[i].C==arr[j].C) find = true; break;

if (find) break;

alert(find)
