score:2
the group lines in your json file should look like "group" : "2"
. also, your json contains a single object (resources
); that's why your document.write
is only called once. you'll need to iterate through the value of resources
:
d3.json("test.json", function(error, graph) {
var resources = graph.resources;
for (var i = 0; i < resources.length; i++) {
var obj = resources[i]
for (var key in obj) {
console.log(key+"="+obj[key]);
}
}
});
will get you
subject=node 1
group=1
...
score:0
i'd like to summarize what i've already wrote in several question's comments.
because posted json file was invalid it was not possible to iterate over it. original json file:
{
"resources":
[
{
"subject": "node 1",
"group" = "1"
},
...
{
"object": "node 6",
"group" = "6"
}
]
}
each line which contains property group = "x"
is wrong. it should be group : "x"
.
those kind of errors/typos are easily overlooked. they can be find out checking json file with proper tool like json validator. in this case jsonlint tool reported:
parse error on line 5:
... "group"="1" } ]
----------------------^
expecting '}', ':', ',', ']'
after fixing format of file, iteration could be done easily using any loop: variable graph
contains object resources, which is an array of objects. each of them contains common property group
.
