Get JSON object from AJAX call

Question

I'm new to AJAX and javascript. In my project, I have to get a json object in my javascript file. I've used spray-json and it shows me the json object in the url. http://localhost:8081/all-modules

{
  "status": "S1000",
  "description": "Success",
  "results": ["module1", "module2", "module3"]
}

My Ajax call

  $.ajax({
        url: 'http://localhost:8081/all-modules',
        dataType: 'application/json',
        complete: function(data){
            alert(data)
        },
        success: function(data){
            alert(data)
        }

It returns an alert [object Object]. What is the issue in here?

Answer 1

just console.log(data) you will see your object.

you can access your value by something like this

data.id //will give you id

it also depend on you json how you are creating check this out for explanation

// if it simply json then access it directly
//Example => {"id":1,"value":"APPLE"}
data.id; // will give you 1 

// if it json array then you need to iterate over array and then get value.
//Example => [{"id":1,"value":"APPLE"},{"id":2,"value":"MANGO"}] then
data[0].id;  // will give you 1 

so your code will be like this

 $.ajax({
    url: 'http://localhost:8081/all-modules',
    dataType: 'application/json',
    complete: function(data){
        alert(data.status);// S1000
        alert(data.description);// Success
        // for results you have to iterate because it is an array
        var len =  data.results.length;
        for(var i=0;i<len;i++ ){
            alert(data.results[i]);
        }
    },
    success: function(data){
        alert(data)
    }
})
