这次给大家带来jscss基础操作总结,jscss基础操作的注意事项有哪些,下面就是实战案例,一起来看一下。

返回上一页:

<button onclick="goBack()">返回上一页</button>
<script>
function goBack(){
window.history.go(-1)     -2即为退后2页
}
</script>

点击回到顶部

document.body.scrollTop = 0
document.documentElement.scrollTop = 0

css中超出变为省略号:

<style>
div{
width:100%;
overflow: hidden;
white-space:nowrap;
text-overflow:ellipsis;
}
</style>

微软雅黑的写法:
1)、“微软雅黑” 转换Unicode编码“\5FAE\8F6F\96C5\9ED1”

div{font-family:”\5FAE\8F6F\96C5\9ED1”}


div内css字体一样是设置为“微软雅黑”
2)、“微软雅黑”使用英文“Microsoft YaHei”

div{font-family:”Microsoft YaHei”}

es6中 数组去重

this.newarr = Array.from(new Set(this.arr))

Object.keys(obj)  ----- 将对象排序输出
obj  要返回其枚举自身属性的对象。--- 要排序的对象
eg:

var anObj = { 100: &#39;a&#39;, 2: &#39;b&#39;, 7: &#39;c&#39; };
console.log(Object.keys(anObj));   // console: [&#39;2&#39;, &#39;7&#39;, &#39;100&#39;]
