When a JavaScript variable refuses to cooperate and won't populate

Question

When a JavaScript variable refuses to cooperate and won't populate

I am currently working with a simple variable that is accepting a JSON Object.

Here is the code snippet:

To maintain privacy, I have sanitized the code to avoid revealing sensitive information.

var server = "00.00.000.00:8800";
var webServices = "http://" + server + "/somedir/ws/";

var networksURL;
var sitesURL;
var resourcesURL;
var componentsURL;

networksURL = webServices + 'config/networks';
sitesURL =  webServices + 'config/sites';
resourcesURL =  webServices + 'config/resources';
componentsURL =  webServices + 'config/components';

// Rest of the code omitted for brevity...

Please refer to the code above for the complete implementation. Thank you.

The issue lies within this section:

return fetchData(networkInfo, function(response){});

The function fetchData does not have a return value. It initiates an asynchronous AJAX request. As a result, the variable networkData will end up as undefined because of the nature of fetchData.

To resolve this, you should utilize the callback function of fetchData like this:

function processNetworkData(netID, callBackFunction) {
    networkInfo = networkURL + "/" + netID + "/data";
    console.log(networkInfo);
    fetchData(networkInfo, callBackFunction);
}

Then proceed with:

processNetworkData(element.id, function(data){
    console.log("Data received: " + data);
});

This implies that your analyzeData cannot have a return value due to its asynchronous nature. You may need to reconsider your overall approach in this scenario.
