Response to a Javascript query on Parse.com

Question

Response to a Javascript query on Parse.com

I have a JavaScript function for querying data from Parse.com, as shown below.

function fetchData() {
var query = new Parse.Query("english");
query.find({
  success: function(results) {
    alert(results);
  },
  error: function(error) {
    // Handle any errors here.
  }
});
}

Although I can see the length of the query response by using results.length in an alert, I am unable to view the actual content inside the results. The alert displays [object Object],[object Object]...

I'm curious about the format of the response - is it JSON or an array? And how can I access the values within the results?

Any help would be appreciated. Thank you!

To view the response of a query in your code, utilize the console.log method:

function displayResults () {
var search = new Search.Query("english");
search.fetch({
  success: function(data) {
    console.log(data);
  },
  error: function(error) {
    // error will be an instance of Search.Error.
  }
});
}

After implementing this code, open Developer Tools(F12) -> Console to observe the returned data.

When working with JavaScript, you have the ability to inspect objects using the console.log method.
The console.log function is exceedingly versatile, as it can accept any number of parameters and data types.
This means you can intermingle strings and objects by simply separating them with a comma.

let myExampleObject = { exampleString: "Greetings Earthlings!" };
console.log("Behold my example object:", myExampleObject);
//Output: Behold my example object: Object {exampleString: "Greetings Earthlings!"}

While the suggestions to use console.log() for printing out objects are valid, there are alternative methods that may be more effective. In addition to console logging, it's advisable to incorporate alert() functions in your development process, especially in success and error blocks.

This precaution is crucial because there may be instances where your code triggers repeated requests to Parse.com indefinitely. Given that Parse.com enforces charges based on request volume per second, unintended financial consequences could arise if excessive requests are unintentionally sent. Utilizing alert() provides a proactive approach as it notifies you each time a call is made, giving you the chance to address any potential issues before they escalate.

Moreover, relying solely on console.log() isn't mandatory to examine data output. Instead, you can directly access object properties (presented in JSON format) by invoking the following code:

query.find({
   success: function(results) {
      alert(results.get("propertyName"));
   },
   // Additional error handling and logic

Using object.id allowed me to retrieve the object id, while I had to utilize object.get('ephrase') to access other parameters.

function retrieveData () {
var query = new Parse.Query("english");
query.find({
  success: function(results) {

      alert("Successfully retrieved " + results.length + " scores.");
    // Perform operations with the returned Parse.Object values
    for (var i = 0; i < results.length; i++) {
      var object = results[i];
      alert(object.id + ' - ' + object.get('ephrase'));
    }

  },

  error: function(error) {
    // error is an instance of Parse.Error.
  }
});

}
