I want to parse dates (string date format to javascript date format), but I have various string date format like YYYY-MM-DD, DD-MM-YYYY and 'DD/MM/YYYY' and so..

Is there any generic procedure or way to convent from these string date format to javascript date format?

Just two? There is also XDate, fecha.js, date-fns, Later.js, Countdown.js, Cubism.js (D3 plugin), js-joda, … ;-)

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));
}

Just go get datejs.

http://www.datejs.com/

...and never bother with writing your own Javascript date functions again.

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
}

Date.parseInvariant() is not a Javascript function.
Actually, Date.parseInvariant in an JScript (Microsoft-only) "Date Type Extensions". "Date extensions are part of the Microsoft Ajax Library and add functionality to the JavaScript Date object." msdn.microsoft.com/en-us/ie/bb310850(v=vs.94)
