我有一个计算功能,其中的一部分显示了实现目标所需的天数.
而不是仅显示我想要计算的天数和天数几个月或几天,几个月和几年,取决于数量.我有一个if语句的分裂,但似乎无法解决数学从例如132天到x天x个月…任何建议？
- // GOAL
- var timeToGoal = Math.round(goal / costPerDay);
- // if more than a year
- if ( timeToGoal >= 365 ) {
- alert('days + months + years');
- // if more than a month but less than a year
- } else if ( timeToGoal >= 30 && timeToGoal <=365 ) {
- alert('Days + months');
- } else {
- alert('days');
- $('#savings-goal span').text(timeToGoal+' days');
- }
解决方法
尝试这样的东西
- function humanise (diff) {
- // The string we're working with to create the representation
- var str = '';
- // Map lengths of `diff` to different time periods
- var values = [[' year',365],[' month',30],[' day',1]];
- // Iterate over the values...
- for (var i=0;i<values.length;i++) {
- var amount = Math.floor(diff / values[i][1]);
- // ... and find the largest time value that fits into the diff
- if (amount >= 1) {
- // If we match,add to the string ('s' is for pluralization)
- str += amount + values[i][0] + (amount > 1 ? 's' : '') + ' ';
- // and subtract from the diff
- diff -= amount * values[i][1];
- }
- }
- return str;
- }
预计这个论点是你想代表的日子差异.它假设一个30天,一年365.
你应该这样使用它
- $('#savings-goal span').text(humanise(timeToGoal));
