    javascript - Type Error: XMLHttp is not a constructor - Stack Overflow

    programmeradmin4浏览0评论

    I have tried with this code in JavaScript as follows:

    var XMLHttpRequest = require("xmlhttprequest");

var xhr = new XMLHttpRequest();
xhr.open("GET", "/",true);
xhr.send();

console.log(xhr.status);
console.log(xhr.statusText);

    When I run this code using node.js at Command Prompt "node ***.js", an error message es out saying that 'TypeError: XMLHttpRequest is not a constructor'. I appreciate for any help for why this error. Thanks.

    • It's got to be because the first line is failing. – Scott Marcus Commented Mar 9, 2018 at 19:52
    • node.js hasn't direct Ajax- API's. You must use Third-Party modules or the net ponent from node.js – Adrian Preuss Commented Mar 9, 2018 at 19:56

    Reset to default 11

    The first line should be:

    var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;

    See the documentation.

    I think you need to load the module as smlhttprequest and demo

    var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
var xhr = new XMLHttpRequest();
