Getting value from object in javascript

问题:

After console.log(item) I got following object.

Object {_value: "106", _id: "opt_zXtP8TOfW2zteOgDIJQDI6Bxx3xSTkl5", _class: "selected", _selected: "selected"}

I want _value from this object. How can I do this?

I tried alert(item.value) but gets undefined

回答1:

You're ignoring the underscore. value and _value are not the same. You need to use:

item["_value"];

Or:

item._value;
