Question

我想解析日期（字符串日期格式为javascript日期格式），但我有各种字符串日期格式，如YYYY-MM-DD，DD-MM-YYYY和'DD/MM/YYYY'等等。

是否有任何通用程序或方法将这些字符串日期格式修改为javascript日期格式？

Answer 1

有两个库可以执行此操作：

Answer 2

此处userFormat字符串可采用以下格式'DD-MM-YYYY'，'YYYY-MM-DD'，'DD/MM/YYYY'等。

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));
}

Answer 3

去get datejs。

...再也不用再写自己的Javascript日期函数了。

Answer 4

function dateParsing(toDate, dateFormat) {
    var dt = Date.parseInvariant(todate, dateFormat); // pass date and your desired format e.g yyyy/M/dd            
    alert(dt); // to check date
}

字符串日期到javascript日期：解析日期
