Example 1: javascript loop through object example

var person={
 	first_name:"johnny",
  	last_name: "johnson",

    "p1": "value1",
    "p2": "value2",
    "p3": "value3"
};

    if (p.hasOwnProperty(key)) {
        console.log(key + " -> " + p[key]);
    }

Example 3: loop over json javascript

var arr = [ {"id":"10", "class": "child-of-9"}, {"id":"11", "class": "child-of-10"}];
    
for (var i = 0; i < arr.length; i++){
  document.write("<br><br>array index: " + i);
  var obj = arr[i];
  for (var key in obj){
    var value = obj[key];
    document.write("<br> - " + key + ": " + value);
  }
}

Example 4: iterate over json data javascript

var arr = [ "one", "two", "three", "four", "five" ];
var obj = { one:1, two:2, three:3, four:4, five:5 };

jQuery.each(arr, function() {
  $("#" + this).text("My id is " + this + ".");
  return (this != "four"); // will stop running to skip "five"
});

jQuery.each(obj, function(i, val) {
  $("#" + i).append(document.createTextNode(" - " + val));
});
