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));
