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) {
(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(){

}
}
if (find) break;
}
alert(find)
