I have following json object:
{ "id": "109",
"No. of interfaces": "4" }
Following lines work fine:
alert(obj.id);
alert(obj["id"]);
But if keys have spaces then I cannot access their values e.g.
alert(obj."No. of interfaces"); //Syntax error
How can I access values, whose key names have spaces? Is it even possible?
This question is related to
javascript
json
The way to do this is via the bracket notation.
var test = {_x000D_
"id": "109",_x000D_
"No. of interfaces": "4"_x000D_
}_x000D_
alert(test["No. of interfaces"]);For more info read out here:
The answer of Pardeep Jain can be useful for static data, but what if we have an array in JSON?
For example, we have i values and get the value of id field
alert(obj[i].id); //works!
But what if we need key with spaces?
In this case, the following construction can help (without point between [] blocks):
alert(obj[i]["No. of interfaces"]); //works too!
