How can i navigate through the json?

Question

I have some JSON which I have in a object but I can seem to return the values a sample of the json is as follows.

{
\"rootLayout\":\"main\",
\"layoutDescriptions         


        

Answer 1

Are you trying to get one of layoutDescriptions with id equals to obj.rootLayout?

var targetLayout = {};
for(var i = 0; i < obj.layoutDescriptions.length; i++) {
    if(obj.layoutDescriptions[i].id == obj.rootLayout) {
        targetLayout = obj.layoutDescriptions[i]; break; 
    }
}

console.log(targetLayout);
