and so..
是否有任何通用程序或方法从这些字符串日期格式修改为javascript日期格式?

推荐答案
此处 userFormat
字符串可以采用以下格式'DD-MM-YYYY'
,'YYYY-MM- DD'
,'DD / MM / YYYY'
等..
Here userFormat
string could be in these format 'DD-MM-YYYY'
, 'YYYY-MM-DD'
, 'DD/MM/YYYY'
etc..
function parseDate(dateString, userFormat) {
var delimiter, theFormat, theDate, month, date, year;
// Set default format if userFormat is not provided
userFormat = userFormat || 'yyyy-mm-dd';
// Find custom delimiter by excluding
// month, day and year characters
delimiter = /[^dmy]/.exec(userFormat)[0];
// Create an array with month, day and year
// so we know the format order by index
theFormat = userFormat.split(delimiter);
//Create an array of dateString.
theDate = dateString.split(delimiter);
for (var i = 0, len = theDate.length; i < len; i++){
//assigning values for date, month and year based on theFormat array.
if (/d/.test(theFormat[i])){
date = theDate[i];
}
else if (/m/.test(theFormat[i])){
month = parseInt(theDate[i], 10) - 1;
}
else if (/y/.test(theFormat[i])){
year = theDate[i];
}
}
return (new Date(year, month, date));
}
