how would I go about accessing a deep value using a single variable in bracket notation?

Question

I am wondering how to do the following- I have the following data:

dta = {
       \"fielddata\": {
           \"text1\": \"4B030C2E-3D53-4DF8-A3535EF377B45DE5\",         


        

Answer 1

var val = "fielddata.text1",
    acc = dta,               // reference the base object
    parts = val.split('.'),  // split the val into an Array of individual parts
    i;

  // Iterate the parts, updating acc each time
for( i = 0; i < parts.length; i++ )
    acc = acc[parts[i]];
