Vue获取DOM元素样式 && 样式更改
在 vue 中用 document 获取 dom 节点进行节点样式更改的时候有可能会出现 ‘style’ is not definde的错误，这时候可以在 mounted 里用 $refs 来获取样式，并进行更改：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<template> <div style="display: block;" ref="abc"> <!-- ... --> </div> </template> <script> export default { mounted () { console.log(this.$refs.abc.style.cssText) } } </script> <strong><span style="color: #ff0000;">结果是 display: block;</span></strong> |

解决Vue方法中setTimeout改变变量的值无效
JS获取当前时间及时间戳相互转换
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
1.获取当前时间的 时间戳 Date.parse(new Date()) 结果：1486347562000 2.获取当前 时间 new Date() 结果：Mon Feb 06 2017 10:19:42 GMT+0800 (CST) 3.将 时间戳 转换成 时间 new Date(1486347562000) 结果：Mon Feb 06 2017 10:19:22 GMT+0800 (CST) 4.将 时间 转换成 时间戳 Date.parse(new Date("2017-02-06 10:30:50")) 结果：1486348250000 |
