1,正则去掉v-html里面的样式和标签
snippet (value) {
// console.log(value.replace(/<[^>]+>/g, '')) // 去掉html标签
return value.replace(/<[^>]+>/g, '').slice(0, 50) + "..." // 截取多少字符
}
2,包含大小写,字符数字四种的至少8位的密码
// 带空格,不包含下划线
let reg1 = /^(?![A-Za-z0-9]+$)(?![a-z0-9\W]+$)(?![A-Za-z\W]+$)(?![A-Z0-9\W]+$)[a-zA-Z0-9\W]{8,}/
// 不带空格
let reg2 = /^(?=.*?[A-Z])(?=(.*[a-z]){1,})(?=(.*[\d]){1,})(?=(.*[\W]){1,})(?!.*\s).{8,16}$/
// 包含下划线
let reg = /(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[\d])(?=.*?[^\sa-zA-Z0-9]).{8,}/
3, 判断是否为空对象
function isEmpty(obj) {
for (key in obj) {
if (obj, hasOwnPropety(key)) {
return false
}
}
return true
}
console.log(isEmpty(obj));
4, 判断是对象还是数组
function getDataType(ao) {
if (ao instanceof Array) {
return 'Array'
} else if (ao instanceof Object) {
return 'Object'
} else {
return 'Data not is Array or Object'
}
console.log(getDataType(arr))
}
3,获取上一周下一周的时间
需求,点击上一周下一周,获取对应的日期
<a style="padding: 0 12px"
@click="shang">上一周</a>
<label>开始时间：</label>
<DatePicker type="date"
format="yyyy-MM-dd"
@on-change="startTime = $event"
:value="startTime">
</DatePicker>
<label class="ml-10">结束时间：</label>
<DatePicker type="date"
format="yyyy-MM-dd"
@on-change="endTime = $event"
:value="endTime">
</DatePicker>
<a style="padding: 0 12px"
@click="xia">下一周</a>
mounted () {
let Nowdate = new Date();
let WeekFirstDay = new Date(Nowdate - (Nowdate.getDay() - 1) * 86400000); // 本周第一天
let WeekLastDay = new Date((WeekFirstDay / 1000 + 6 * 86400) * 1000);// 本周第最后一天
this.startTime = WeekFirstDay
this.endTime = WeekLastDay
},
methods: {
shang () {
this.getLastWeekData(this.startTime, this.endTime)
},
xia () {
this.getNextWeekData(this.startTime, this.endTime)
},
getLastWeekData (start, end) {
let startVal = new Date((start / 1000 - 7 * 86400) * 1000)
let endVal = new Date((end / 1000 - 7 * 86400) * 1000)
this.startTime = startVal
this.endTime = endVal
},
getNextWeekData (start, end) {
let startVal = new Date((start / 1000 + 7 * 86400) * 1000)
let endVal = new Date((end / 1000 + 7 * 86400) * 1000)
this.startTime = startVal
this.endTime = endVal
},
4, 拿到所有数据,前端自己分页
// initListDatas所有 的数据
// userLists写在page组件上的data数据
this.userLists = this.initListDatas.slice((this.currentPage - 1) * this.pageSize, this.currentPage * this.pageSize)
