js根据当前日期并展示为2018-08-13格式

1、js获取当前日期var date = new Date();var seperator1 = "-";

2、js获取当前日期 的年月日 var year = date.getFullYear(); var month = date.getMonth() + 1; var strDate = date.getDate();

3、js将获得的年月日进行字符串拼接if (month >= 1 && month <= 9) { month = "0" + month; } if (strDate >= 0 && strDate <= 9) { strDate = "0" + strDate; } var currentdate = year + seperator1 + month + seperator1 + strDate;

4、完整代码//获取当前日期2018-08-13function getNowFormatDate() { var date = new Date(); var seperator1 = "-"; var year = date.getFullYear(); var month = date.getMonth() + 1; var strDate = date.getDate(); if (month >= 1 && month <= 9) { month = "0" + month; } if (strDate >= 0 && strDate <= 9) { strDate = "0" + strDate; } var currentdate = year + seperator1 + month + seperator1 + strDate; return currentdate;}js中直接引用var today =getNowFormatDate()；此时today ='2018-08-13'
