    You need to use getMonth() and getFullYear() on returned date object to format date as per requirement. Also, you need to add 1 to returned month as getMonth method is 0 index based:
(d.getMonth()+1).toString() + d.getFullYear().toString()
 
    
    Try this
function formatDate(date) {
    var d = new Date(date),
        month = '' + (d.getMonth() + 1),    
        year = d.getFullYear();
    if (month.length < 2) month = '0' + month;   
    return [month,year].join('');
}
Call this function : formatDate('March 2018') // output : 032018
 
    
    Try converting the date object you end up with to a string:
Try the following snippet, just change var  d = new Date() to var  d = new Date($('.selected_month').find("td:first").text()).
var  d = new Date();
var twoDigitMonth = (d.getUTCMonth() + 1).toString().padStart(2, "0");
var year = d.getUTCFullYear();
var result = twoDigitMonth + year;
console.log(result);<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
    
    ...or try this...
console.log(
    new Date("March 2018")
    .toLocaleDateString('en-EN', {month: '2-digit',year: 'numeric'})
    .replace('/','')
)
