问如何在.JSON文件中加载本地.js文件

EN

node main.js

$.getJSON("test.json", function(json) {
    console.log(json); // this will show the info it in firebug console
});

$.getJSON is not a function even though I am requiring jQuery.

 function loadJSON(callback) {   

    var xobj = new XMLHttpRequest();
        xobj.overrideMimeType("application/json");
    xobj.open('GET', 'my_data.json', true); // Replace 'my_data' with the path to your file
    xobj.onreadystatechange = function () {
          if (xobj.readyState == 4 && xobj.status == "200") {
            // Required use of an anonymous callback as .open will NOT return a value but simply returns undefined in asynchronous mode
            callback(xobj.responseText);
          }
    };
    xobj.send(null);  
 }

xobj.overrideMimeType is not a function

node main.js
