JSON - Access field named '*' asterisk
I am trying to access a JSON field that has the key '*'
:
{
"parse": {
"text": {
"*": "text i want to access"
}
}
}
Neither myObject.parse.text.*
nor myObject.parse.text[0]
works.
I have searched for an hour but haven't found any hint that an asterisk has special 开发者_StackOverflow中文版meaning. If I just traverse the complete tree and make String comparison with if (key == "*")
I can retrieve the text, but I would like to access this field directly. How can I do that?
json.parse.text["*"]
Yucky name for an object member.
Asterisks have no special meaning; it's a string like any other.
myObject.parse.text.*
doesn't work because *
isn't a legal JS identifier. Dot notation requires legal identifiers for each segment.
myObject.parse.text[0]
doesn't work because [n]
accesses the element keyed by n
or an array element at index n
. There is no array in the JSON, and there is nothing with a 0
key.
There is an element at the key '*'
, so json.parse.text['*']
works.
Try use the index operator on parse.text
:
var value = object.parse.text["*"];
try to use
var text = myObject.parse.text['*']
You could do:
var json = {"parse":
{"text":
{"*":"text i want to access"}
}
}
alert(json.parse.text['*']);
