My name is Taniguchi am im new at jquery. im developing a jquery code to get latitude and longitude from bing map rest service, i already have the code but i have trouble to understand part of it.

function getcordinate(executionContext){

var attribute = executionContext.getEventSource();

var Rua = atribute.getvalue;

var proxy = ' https://cors-anywhere.herokuapp.com/';

var bingURL = " http://dev.virtualearth.net/REST/v1/Locations/BR/query='" + Rua + "'&key=AlBxRwA5l41uHKOuC8_cNHwnAe8trlfDFqr5h-O7iz_jCPGaIuW4RhZZhMjOCj8C";

var finalURL = proxy + bingURL;

$.ajax({

type: 'GET',

url: finalURL,

success: function (data) {

debugger;

if (data.resourceSets[0].estimatedTotal > 0) {

var loc = data.resourceSets[0].resources[0].point.coordinates;

//$("#results").html('latitude:' + loc[0] + ', longitude:' + loc[1]);

Xrm.Page.getAttribute("crd4c_latitude").setValue( loc[0].toString() );

Xrm.Page.getAttribute("crd4c_longitude").setValue(loc[1].toString());

Xrm.Page.getControl("crd4c_latitude").setDisabled(true);

Xrm.Page.getControl("crd4c_longitude").setDisabled(true);

}

else {

alert("sorry that address cannot be found");

}

},

error: function (jqXHR, textStatus, errorThrown) {

debugger;

}

});

}

what the function(data) is doing ?
