Question

i have the below response from server:

{"result":{"js":"memo","text":"some value","tag":"some tag"}}

in the client side (using jquery), i am parsing this as below:

var obj = JSON.parse(resp);

i have a variable defined as below:

var prop = $(this).attr('pId'); -> returns “text”

i am looking for something like using this variable prop with the json object as follow:

obj.result.prop : obj.result.text = i am expecting “some value” to be obtained

is there a specific way to get a value like above?

Answer 1

Use bracket notation.

var prop = 'text';
console.log(obj.result[prop]); // prints "some value"
// equivalent to
console.log(obj.result.text);
