Accessing elements in a JSON object was straightforward with the

I need help with accessing values from a JSON object based on a key name stored in a variable. My colleague has written a function to extract keys from the JSON object and compare them with the ones we are interested in. However, I am struggling with figuring out how to use the variable containing the key name to retrieve the corresponding values. Although idx holds the member name, it is not a direct member of the object. How can I utilize idx to access obj?

$.each(JSON.parse(data[0][i]), function(idx, obj){
            for(var j = 0; j < searchKeys.length; j++){
                if (idx == searchKeys[j]) {
                    //I am unsure how to accurately achieve this
                    injectLoc.innerHTML += panelMaker(obj.idx, idx, "green", "gears");
                }
            }
});

Answer №1

Accessing an element in JavaScript works similarly to how you would access an element in an array.

For example, you can use the syntax var item = arr[index];

In JavaScript, you can access object properties using obj.prop, obj["prop"], or obj[index] where index === "prop".

When working with JSON data,

To access elements by index, you can use obj[idx]
To access values by keys, you can use obj.key or obj["key"]
Keep in mind that if the key contains spaces, you should use obj["key"]

To loop through the keys of an object, you can utilize the Object.keys() method. The function could be structured in this manner:

Object.keys(data).forEach((key, value) => {
  if(value === key){
    container.innerHTML += createPanel(data[key], value, "blue", "wrenches");
  }
})
