localStorage get value using angular

Question

I looked at some examples, but can't seem to figure this out. Basically I have a contact form in an ionic app that allows a user to contact a listing owner.

When they submit the form I want to store the ad id in local storage so they can't repeatability submit it over and over.

I need to be able to store json array and then check the results. If the ad id is in session storage don't show the form else show it.

I am currently doing this, which seems to store the ad ids in an array, but how do I loop through to check if an id exists? I tried angular forEach, but results come as an object.

    // Parse any JSON previously stored in allEntries
  var existingEntries = JSON.parse(localStorage.getItem("store_owner_ad_contacts"));
  if(existingEntries == null) existingEntries = [];

  var adId = {
    "id":$scope.adId
  };
  // Save allEntries back to local storage
  existingEntries.push(adId);
  localStorage.setItem("store_owner_ad_contacts", JSON.stringify(existingEntries));

  var values = JSON.parse(localStorage.getItem("store_owner_ad_contacts"));
  angular.forEach(values, function(value, key) {

  // ^ This is coming as an object how can I get the key value?

   if(value == adId){
   //form has been submitted before
   }else{
   // showformVar = true 

    console.log(key + ': ' + value);
  });

My storage looks like this

      [{"id":"100033"},{"id":"100035"},{"id":"1000336"}]

How do I get id value? (e.g 1000033)

Answer 1

In your loop you have an object, so just access id property like you do with an object: object.yourProperty or object[yourProperty]

var values = JSON.parse(localStorage.getItem("store_owner_ad_contacts"));

values.forEach(values, function(item, i) {

   // you get object like this {id: "100033"}
   // so to access id do like normal object

   if (item.id === '100033') {
     // do something
   }

});

// inside forEach loop
var k = 0;
for(k in value) {
     // u can get the key in this way (k) 
}
