This introduces Djblets.parseQueryString(), which will take a query

string or a URL containing one and parse it. It understands key/value

pairs, standalone keys (which will be assigned the value null), and

optionally supports storing multiple values for a key as an array.


Unit tests were added that test all the standard query string cases.

 








  


 
 

  
Unit tests pass.


Used this in an upcoming change in Review Board.

    Given the default value for options, I think you don't need this check and can just use options.allowMultiValue. If someone passes in something that's falsy and not an object they're using the API wrong.

      We need to call it in both cases. Might as well only do it once.

      It's not like it will ever be called more than once--this is a conditional.
      

      This is fewer LOC, avoids the multiple-assignment of "key", and is nicer to read IMO:
      

      

      if (j === -1) {
    key = decodeURIComponent(queryParam);
    value = null;
} else {
    key = decodeURIComponent(queryParam.substr(0, j));
    value = decodeURIComponent(queryParam.substr(j + 1));
}
