I thought so and tried:
$(".EncodedDescriptionField").each( function(index, element ){
var hereWeAre = $(this).text();
var decodedString = atob(hereWeAre);
console.error(hereWeAre);
console.error(decodedString);
});
this brings up an exception:
Uncaught DOMException: Failed to execute 'atob' on 'Window': The string to
be decoded is not correctly encoded.
I've also double-checked the values - they are correct. For example, when I
replace with the following:
var decodedString = atob("Q29va2llcyBvbmU=");
it decodes just fine, and the string itself I pick right from there -
that's the value it has when it throws exception.
Have no slightest clue what could possibly go wrong.
