1.文字渐变:
background: linear-gradient(to bottom, #f0fcff, #a1e1f3);
-webkit-background-clip: text;
color: transparent;
2.上下滚动
3.css文本超出...
white-space:nowrap;overflow:hidden;text-overflow:ellipsis;width:();
//
width: 200px !important; //限制文本宽度
word-wrap: break-word; //自动换行
word-break: break-all; //自动换行(兼容字母)
overflow: hidden; //超出隐藏
text-overflow: ellipsis; //溢出显示省略号
display: -webkit-box;
-webkit-line-clamp: 3; //显示3行
-webkit-box-orient: vertical;
4.首行缩进
p{
text-indent: 2rem;
}
5.vue v-for循环里面点击当前元素点击显示和隐藏
msgShow(index){
this.activeIndex = this.activeIndex === index ? !index : index;
}

6.查当前时间
mounted
var date = new Date();
var seperator1 = "-";
var seperator2 = ":";
var month = date.getMonth() + 1<10? "0"+(date.getMonth() + 1):date.getMonth() + 1;
var strDate = date.getDate()<10? "0" + date.getDate():date.getDate();
var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
+ " " + date.getHours() + seperator2 + date.getMinutes()
+ seperator2 + date.getSeconds();
this.time = currentdate
7.tab切换栏

8.默认选中
$("#q1").trigger("click")
9.存取数据
citys: [],
var time = ['一', '二', '三', '四', '五', '六', '日']
var stime = this.temp.fieldOpenDate
time.forEach((v) => {
stime.forEach((a) => {
if ((a === v)) {
this.citys.push(a)
return
}
})
})
this.temp.fieldOpenDate = this.citys.join(',')

echarts
提示信息:{a}(系列名){b}(类目值){c}(数值)
模板变量有 {a}、{b}、{c}、{d},分别表示系列名,数据名,数据值,百分比。{d}数据会根据value值计算百分比
tooltip: {
show: true,
formatter: '{b}: {c}%'
},
报错:Error in created hook: “Cannot read properties of undefined (reading ‘getAttribute‘)“
将调用echars的方法从created(){},放到mounted(){}里边
