All the above methods will fail if *** is not found in the input string.

var delimiter = '***';
var str = 'Ice Creams***Cone***Frosty';
var strParts = str.split('***'); //returns an array
var numParts = strParts.length;
if(numParts > 0) {
   console.log(strParts[strParts.length - 1]);
} else {
   console.log('Delimiter ' + delimiter + ' not found in input string');
}

You can get the index of the last *** by using str.lastIndexOf('***').

For getting the last field you can use str.substring(index)

var seperator = '***'

// shifting index by seperator length
var i = str.lastIndexOf(seperator) + seperator.length;
var lastSubString = str.substring(i);

Just use the substr() and lastIndexOf() method

Sample

function extractEverythingAfter(value, seperator) {
   return value.substr(value.lastIndexOf(seperator) + seperator.length)
}

alert(extractEverythingAfter('Ice Creams***Cone***Frosty', '***'));
alert(extractEverythingAfter('Ice Creams***Cone', '***'));

You can split() your string on *** and then use .pop() to get the last element of the resulting array:

var str = 'Ice Creams***Cone***Frosty';
var last = str.split("***").pop();
