javascript中日期轉換成時間戳記的小例子_javascript技巧

複製程式碼 程式碼如下:

/**
* 日期轉換成時間戳
* 日期格式2011-02-02 21:12:13
* time_str:日期段2011-02-02
* fix_time:時間段21:12: 13
*/

/***/

*/var time = (new Date()).getTime();

if(time_str) {//有日期段
var str = time_str.split('-');
if (3 === str.length) {

var year = parseInt( str[0]) - 0;

var month = parseInt(str[1]) - 0 - 1;//月份是從0開始的
var day = parseInt(str[2]) - 0;

if(fix_time) {//有時間段
var fix = fix_time.split(':');
if (3 === fix.length) {
var hour = parseInt( fix[0]) - 0;
var minute = parseInt(fix[1]) - 0;
var second = parseInt(fix[2]) - 0;
time = (new Date(yearInt(fix[2]) - 0;
time = (new Date(yearInt(fix[2]) - 0;
time = (new Date(year , month, day, hour, minute, second)).getTime();
}
} else {
time = (new Date(year, month, day)).getTime();
}
}

}

//getTime()獲取的時間戳到了毫秒數
time = time / 1000;//轉到到秒數

return time; }
