项目经验：js生成当前时间的月初00:00:00到月末23:59:59

中间加了12个月大小月以及2月份28天的特殊情况分析

function morenDate(){var date=new Date();var month=date.getMonth()+1;if(month<10){month = "0"+month;}var starttime = date.getFullYear()+'-'+(month)+'-01 00:00:00';var endtime = null;if(month==02){endtime = date.getFullYear()+'-'+(month)+'-28 23:59:59'; }if(month==01||month==03||month==05||month==07||month==08||month==10||month==12){endtime = date.getFullYear()+'-'+(month)+'-31 23:59:59'; }if(month==04||month==06||month==09||month==11){endtime = date.getFullYear()+'-'+(month)+'-30 23:59:59'; }document.getElementById("hsjl.startTime").value = starttime;document.getElementById("hsjl.endTime").value = endtime;}
