项目中常用的js方法(持续更新)
<script> var utils = { //时间戳转日期(timestamp:时间戳 默认当前时间) dateFormat: function(timestamp = new Date().getTime()){ let date = (new Date(timestamp + 8 * 3600 * 1000)); return date.toJSON().replace("T", " ").substr(0, 19); }, //数组排序去重(arr:数组,sequence:正序/倒序 默认正序) arrFromat: function(arr, sequence = "z"){ if(sequence == "z"){ return [...(new Set(arr.sort(function(a, b){ return a - b})))]; }else{ return [...(new Set(arr.sort(function(a, b){ return b-a})))]; } } } </script>
