You can use combination of [substring()][1] and [lastIndexOf()][2] to get the last element.

str = "~test content ~thanks ok ~fine";    
strFine =str.substring(str.lastIndexOf('~'));
console.log(strFine );

You can use [split()][4] to convert the string to array and get the element at last index, last index is length of array - 1 as array is zero based index.

str = "~test content ~thanks ok ~fine";    
arr = str.split('~');
strFile = arr[arr.length-1];
console.log(strFile );

OR, simply call pop on array got after split

str = "~test content ~thanks ok ~fine";    
console.log(str.split('~').pop());
