javascript - Set a cookie in Angular if one does not exist

I want to see if a cookie has been set in Angular, and if it doesn't find a cookie, it will create a new one.

Right now I'm using this:

    if ($cookies.get('storedLCookie').length != 0) {
       $cookies.put('storedLCookie','Oatmeal');
    }

It doesn't seem to be working, though. Is there another way to test if a cookie is set in Angular?

Sorted by: Reset to default 6

you can simply do this to check it:

var favoriteCookie = $cookies.get('cookieval');

  if ( favoriteCookie ) {
    //exists
  } else {
    //not exists
  }

The data store in cookie is string or number. When it's a number, you should't judge it by length. Test the following:

var a = 3
console.log(a.length) // will return undefined

I think you can just write the following instead:

if ($cookies.get('storedLCookie')) {
   $cookies.put('storedLCookie','Oatmeal');
}
