<h2>js中怎么把时间时间字符串类型转换成时间类型</h2><p>1、如果变量是字符串则js的加号便会把两个及多个字符串拼接成一个。</p><p>2、为了让js能够对变量的数据进行加或者其他运算则可用parseInt来把字符串变为整数。</p><p>3、如果是包含有小点的字符串在用parseInt转换时会直接把小点后面的数字忽略掉滴。也就是直接取整数而不是四舍五入计算。</p><p>4、所以对于有小点的字符串便可以用parseFloat来转换。</p><p>5、所以便可以用toFixed()来保留小数的位数。</p><p>6、这样JS便可以得到两数运算比较精确的数字结果了。</p><p>vars="2005-12-1509:41:30";</p><p>vard=newDate(Date.parse(s.replace(/-/g,"/")));</p><p>d.getMonth(); 月</p><p>d.getDate();日</p><p>d.getYear();年测试可以 谢谢方法一：<br>var temper=2009-6-28 15:23 <br>var dt = new Date(temper.replace(/-/,/)) <br>alert(dt) <br><br>方法二：<br>function ConvertDateFromString(dateString) { <br>if (dateString) { <br>var arr1 = dateString.split( ); <br>var sdate = arr1.split('-'); <br>var date = new Date(sdate, sdate, sdate); <br>return date; <br>} <br>}<br>获得一个月中的总天数：<br>function GetDayInMonth(day) { <br>var today = day; <br>var year = today.getFullYear(); <br>if (year < 2000) year += 1900; // Y2K fix <br>var month = today.getMonth(); <br>var monarr = new Array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31); <br>if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) <br>monarr = 29; <br>return monarr; <br>}在js里面怎么把时间类型转换成字符串<br>方法一：<br>var temper="2009-6-28 15:23" <br>var dt = new date(temper.replace(/-/,"/")) <br>alert(dt) <br><br>方法二：<br>function convertdatefromstring(datestring) { <br>if (datestring) { <br>var arr1 = datestring.split(" "); <br>var sdate = arr1.split('-'); <br>var date = new date(sdate, sdate, sdate); <br>return date; <br>} <br>}<br>获得一个月中的总天数：<br>function getdayinmonth(day) { <br>var today = day; <br>var year = today.getfullyear(); <br>if (year < 2000) year += 1900; // y2k fix <br>var month = today.getmonth(); <br>var monarr = new array(31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31); <br>if (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) <br>monarr = 29; <br>return monarr; <br>}var str = 2010-03-22;<br> var val = Date.parse(str);<br>var newDate = new Date(val);<br> alert(newDate);function transDateFormat(d) {<br>var d_elements = new Array();<br>var monthE2N = {Jan:1,Feb:2,Mar:3,Apr:4,May:5,Jun:6,Jul:7,Aug:8,Sep:9,Oct:10,Nov:11,Dec:12};<br>d_elements = d.split( );<br>return d_elements+-+monthE2N]+-+d_elements;<br>}<br>alert(transDateFormat(2004 May 26));</p><p><img src='https://www.dfrlyy.com/zb_users/upload/2022/02/20220204212643_52875.png' alt='js日期转换为时间戳'></p><h2>vue.js怎样将时间戳转化为日期格式</h2><p>通过vue.js filter实现将时间戳转换为自定义标准时间格式方法如下：</p><p><!-- js代码 --></p><p>$().ready(function() {</p><p><!-- 自定义filter名称为'time' --></p><p>Vue.filter('time',</p><p><!-- value 格式为13位unix时间戳 --></p><p><!-- 10位unix时间戳可通过value*1000转换为13位格式 --></p><p>function(value) {</p><p>var date = new Date(value);</p><p>Y = date.getFullYear(),</p><p>m = date.getMonth() + 1,</p><p>d = date.getDate(),</p><p>H = date.getHours(),</p><p>i = date.getMinutes(),</p><p>s = date.getSeconds();</p><p>if (m < 10) {</p><p>m = '0' + m;</p><p>if (d < 10) {</p><p>d = '0' + d;</p><p>if (H < 10) {</p><p>H = '0' + H;</p><p>if (i < 10) {</p><p>i = '0' + i;</p><p>if (s < 10) {</p><p>s = '0' + s;</p><p><!-- 获取时间格式 2017-01-03 10:13:48 --></p><p>// var t = Y+'-'+m+'-'+d+' '+H+':'+i+':'+s;</p><p><!-- 获取时间格式 2017-01-03 --></p><p>var t = Y + '-' + m + '-' + d;</p><p>return t;</p><p><!-- html代码 --></p><p><!-- 在需要转换格式的位置使用名为time的vue.js filter --></p><p><td>{{tab2.fb1 | time}}</td></p>
