How to push data to a nested Object

Question

How can I push another element to the variables property from the below object?

  var request = {
    \"name\": \"Name\",
    \"id\": 3,
    \"r         


        

Answer 1

You have to "navigate" properly in your object:

request.rules[0].tags[0].variables.push({
  "variable":"var3",
  "matchType": "Regex",
  "value": ".*"
})

request['variables'] will just try to find the variables key in root of the request object. This key is simply not defined but is nested in your object/array structure.

Answer 2

Try like this:

object = {"variable": "var3", "matchType": "Regex", "value": ".*"};
request.rules[0].tags[0].variables.push(object);

Answer 3

dot operator(.) can be used to get the value of a particular object property.

square brackets ([]) can be used to access an element of an array.

Now the answer to your question:

request.rules[0].tags[0].variables.push({
"variable": "var3", 
"matchType": "Regex", 
"value": ".*"
});

here, [0] specifies the first element of your array.

Answer 4

Try:

request.rules[0].tags[0].variables.push({
  "variable":"var3",
  "matchType": "Regex",
  "value": ".*"
})

variables is into tags, and tags is into rules.

Answer 5

request.rules[0].tags.variables[0].push({
  "variable":"var3",
  "matchType": "Regex",
  "value": ".*"
});

You have to navigate in your array. Replace the 0 inside the [] to select the item from the array. (0 is first entry, 1 is second entry etc).
