Extracting data from JsonArray using JS/jQuery

I have a JsonArray something like this.

var json_array = [{ "text": "id", "size": 4}, { "text": "manifesto", "size": 4}, { "text": "also", "size": 4}, { "text": "leasing", "size": 4}, { "text": "23", "size": 4}];

Is there anyway to get me all the "text" property of this json_array in another array using Javascript/jQuery?

like:

var t_array = ["id","manifesto","also"....]

You can use $.map() to project the relevant information from your existing array into a new one:

var t_array = $.map(json_array, function(item) {
    return item.text;
});

something like:

var t_array = [];
$.each(json_array,function(i,o) {
  t_array.push(o.text);
})

I think you'll need to build t_array by looping through json_array

var t_array = [];

for (var i=0; i< json_array.length; i++)
    t_array.push(json_array[i].text);
