If I have an object like this:
var item = {
id: '1',
description: 'something'
}
then how do I extract one of these values? If I do
alert($(item.id));
then I just get an alert saying 'Object object'. I had a look at this post: Getting the base element from a jQuery object and tried to invoke
alert($(item).get(0));
But with the same result.
Also, from a terminology point of view what are objects like this called so that next time I can be a bit more specific?
Just use:
alert(item.id);
This: $(item.id) wraps item.id into a jQuery object, that's why you get 'Object object'
PS
What you're creating is an object in object literal notation, that is a set of comma-separated name/value pairs inside curly braces.
console.log(item.id)
$() returns a jQuery object.
Try this out:
alert($item .prop('id'));
Using normal procedure:
alert(item.id);
Using jQuery :
alert($(item).get(0).id);
NOTE
$(item) -> return an array
$(item).get(0) -> return object which is equal to (var item)
$(item).get(0).id -> return id value
alert(item.id);?jQueryis not a king of javascript, you shouldn't need thy king everytime..
