What is the best way to transform text into a string using Javascript?

I am currently developing an AngularJs application.

One of my challenges involves retrieving data from the backend in Base64 encoded format.

Despite successfully decoding the data, I find that it is presented in text format without any quotation marks, which results in undefined content when attempting to display it.

Is there a method available for converting this text into a recognizable string format?

Below is an excerpt of my code:

   //Encoded data
    templateData.content = "U1lOVEFYX1ZFUlNJT04gMTMKCkdFTkVSSUNfU09VUkNFICJTeXNfU3lzbG9nU3RyZWFtaW5nIgpERVNDUklQVElPTiAiVGhpcyBwb2xpY3kgbm9ybWFsaXplcyB0aGUgc3lzbG9nIG1lc3NhZ2VzIGFuZCBjb3ZlcnRzIHRvIEpTT04gZGF0YS4KVGhlIGxpc3Qgb2YgbG9nIGZpbGVzIGFyZSByZWFkIGZyb20gJy9ldGMvcnlyLmNvbmYnIG9yJyAvZXRjL3N5c2xvZy5jb25mJyAoYmFzZWQgb24gdGhlT1MsdmVyc2lvbikuCkZvciBlLmcuIFwiL3...

The issue arises as AngularJs fails to recognize the data type, resulting in an undefined output.

I attempted using the toString method and also tried adding quotation marks around the data, but these approaches were unsuccessful in resolving the problem.

Could someone provide guidance on how to properly convert this data into a string format that can be utilized by AngularJs?

Answer №1

If you want to decode a string in most browsers, you can utilize the built-in method called atob().

Simply execute

atob(templateData.content)

in the browser console or angular component to receive the decoded string.
