JavaScript function, which reads connections between objects
- by Nikita Sumeiko
I have a JavaScript literal:
var members = {
"mother": {
"name" : "Mary",
"age" : "48",
"connection": {
"brother" : "sun"
}
},
"father": {
"name" : "Bill",
"age" : "50"
},
"brother": {
"name" : "Alex",
"age" : "28"
}
}
Than I have a function, which should read connections from the literal above. It looks like this:
function findRelations(members){
var wires = new Array();
var count = 0;
for (n = 0; n < members.length; n++){
alert(members.length); // this alert is undefined
if (members[n].connection){
for (i = 0; i < members[n].connection[0].length; i++){
var mw = new Array();
var destination = 0;
for (m = 0; m < members.length; m ++){
if (members[m] == members[n].connection[0]){
destination = m;
mw = [n, destination];
wires [count] = mw;
count++;
}
}
}
}
}
return wires;
}
However, when I run this function, I get nothing. And the first alert, which is placed inside the function shows 'undefined' at all.
findRelations(members);
alert("Found " + wires.length + " connections");
I guess that's because of JavaScript literal. Could you suggest how to change a function or perhaps to change litteral to JSON array to get it work?! And at the end to get 'm' and 'n' values as numbers.
