How do I loop through or enumerate a JavaScript object? 29 answers

var obj = {"options": {"1": "All locations", "2": "Egypt", "3": "El Alamein", "4": "Marsa matrouh", "5": "Sharm el sheikh "}}

for(var item in obj.options) {
  console.log(obj.options[item]);
}

For iterating over dictionary you can sue this:

var dict = obj.options;
Object.keys(dict).forEach(function(key) {
    console.log(key +': '+ dict[key]);
});

to know only the length you can simply use:

Object.keys(dict).length;

使用for in循环

var obj = {"options": {"1": "All locations", "2": "Egypt", "3": "El Alamein", "4": "Marsa matrouh", "5": "Sharm el sheikh "}};

var ul = document.querySelector('ul');
for (var index in obj.options) {
  var li = document.createElement('li')
  ul.appendChild(li);
  li.innerHTML = index + ": " + obj.options[index];
   
}

<ul ></ul>
