I imagine this is really basic and I'm missing something obvious.
I want to access the values in a variable called graph_data which is holding the following JSON object:
graph_data= {"data":[0,0,0,0,0,0,0.1,0.4,0,0,8.2,7,5.1,0,0,0,0,0,0,0,0,0,0,0,0]}
When I try to get graph_data.data.length I get an error that graph_data.data is "undefined".
I can't seem to get graph_data.data[0] to return anything either.
What am I missing here?
Your code works fine:
graph_data = {"data":[0,0,0,0,0,0,0.1,0.4,0,0,8.2,7,5.1,0,0,0,0,0,0,0,0,0,0,0,0]};
console.log(graph_data.data.length); // Outputs 25
Are you sure you have an object literal and not a string?
If you have the latter you need to parse it with JSON.parse :
graph_data = JSON.parse('{"data":[0,0,0,0,0,0,0.1,0.4,0,0,8.2,7,5.1,0,0,0,0,0,0,0,0,0,0,0,0]}');
You'll need a parser for older browsers without native JSON support like json2.js
Works for me...
graph_data= {"data":[0,0,0,0,0,0,0.1,0.4,0,0,8.2,7,5.1,0,0,0,0,0,0,0,0,0,0,0,0]};
for (var i = 0; i < graph_data.data.length; i++){
$("body").append(graph_data.data[i]+"<br/>");
}
