Javascript issue while validating dates

Question

In our application,we are using the javascript method, which validates credit card expiry date and returns true if the expiry date is greater than current date. A user reported that the application is not accepting the expiry date 08/2014 in IE 9 browser. When we launched IE in user machine,it opened in IE 9 Compat view browser mode and IE7 Document Standards.The method is failing only for the expiry dates 08/2014 and 09/2014. When we manually changed the browser mode to IE 9 and standards to IE9 ,it worked.I am not able to understand why IE is opening with IE9 Compat view mode and IE 7 standards.Do we need to enforce the IE to always open in IE9?

fnValidateExpiryDate('08/2014','02/20/2014');`

function fnValidateExpiryDate(expiryDate , currentDate) {

    var regexp = /^((0[1-9])|(1[0-2]))\/(\d{4})$/;

    if (!regexp.test(expiryDate)) {

        return false;
    }

    var userDate = expiryDate.split('/');
    var configDate = currentDate.split('/');
    if (parseInt(userDate[1]) < parseInt(configDate[2])) {
        return false;
    }
    if ((parseInt(userDate[1]) == parseInt(configDate[2])) && (parseInt(userDate[0]) < parseInt(configDate[0]))) {
        return false;
    }
    return true;
}

The use case provided seems to work just fine: http://jsfiddle.net/XRf3T/. How do you generate current date? — scrappedcola, Feb 13 '14 at 16:43
The current date is generated from DateTime.Now.ToString("MM/dd/yyyy") — user3306829, Feb 13 '14 at 16:46
yes DateTime is C# system library. It generates the date in this format '02/20/2014' — user3306829, Feb 13 '14 at 16:51
If `expiryDate` is coming in from user input into a text box you will want to trim off all leading or trailing spaces `expiryDate.replace(/\s/g, '');` — scrappedcola, Feb 13 '14 at 19:15
The trimming off leading and trailing spaces is already handled and it is invoked before invoking this method. — user3306829, Feb 14 '14 at 04:06
You can include MetaTag in your page to enforce IE 9 standards Refer this link http://stackoverflow.com/questions/13949858/why-does-ie9-opens-in-document-mode-as-ie7-standards — kishore, Feb 19 '14 at 19:40
