DocuSign API-JavaScript

Question

Afternoon! 下午！ I am very new to JavaScript and the DocuSign API. 我是JavaScript和DocuSign API的新手。 I tried following the sample, but I am getting a ReferenceError. 我尝试按照示例进行操作，但是遇到了ReferenceError。

For testing purposes, I have async.js, fs.js, request.js, and require.js at the root of the folder on my PC along with the test HTML doc 为了进行测试，我在PC上文件夹的根目录中有async.js，fs.js，request.js和require.js以及测试HTML文档

HTML: HTML：

<html>
<head>
        <script src="require.js"></script>
        <script src="example.js"></script>

</head>

<body>
<div id="message"></div>
</body>

</html>

I am getting the following error: ReferenceError: async is not defined async.waterfall( 我收到以下错误：ReferenceError：未定义async async.waterfall（

Below is the example.js code I got from the DocuSign website, slighlt adjusted based on another error around the require function: 以下是我从DocuSign网站获得的example.js代码，根据require函数周围的另一个错误对它进行了调整：

// Request Signature on a Document (JavaScript)

// To run this sample
//  1. Copy the file to your local machine and give .js extension (i.e. example.js)
//  2. Change "***" to appropriate values
//  3. Install async and request packages
//     npm install async
//     npm install request
//     npm install fs
//  4. execute
//     node example.js 
//

//var     async = require("async"),     // async module
//        request = require("request"),     // request module
//      fs = require("fs");         // fs module

require(["request"], function (request){});
require(["async"], function (async){});
require(["fs"], function (fs){});

Again, I am very new to this, so any help would be very appreciated, thanks in advance! 再次，我对此很陌生，因此，非常感谢您的帮助，在此先感谢您！

UPDATE - after realizing I could not takw pieces of node.js to use on QuickBase code pages, I attempted the below two coding options, neither worked...any ideas what I am doing wrong? 更新-在意识到我无法在QuickBase代码页上使用的node.js片段之后，我尝试了以下两个编码选项，但都没有起作用……任何想法我做错了什么？

var xhr = createCORSRequest('GET', urlLoginCall);
xhr.withCredentials = true;
xhr.setRequestHeader('X-DocuSign-Authentication', jsonLoginCall);
xhr.send(); 
xhr.onload = function() {
    var responseText = xhr.responseText;
    alert(responseText);
};
xhr.onerror = function() {
    alert('There was an error!');
};

and 和

$.ajax({
    type: 'GET',
    url: urlLoginCall,
    headers: {
        'X-DocuSign-Authentication': jsonLoginCall
    },
    xhrFields: {
        withCredentials: true
    },
    success: function() {
        alert("success");
    },
    error: function() {
        alert("failure");
    }
});

Via Fidler, I always get this as the request header: 通过Fidler，我总是将其作为请求标头：

OPTIONS /restapi/v2/login_information HTTP/1.1
Host: demo.docusign.net
Connection: keep-alive
Access-Control-Request-Method: POST
Origin: https://twmts.quickbase.com
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.146 Safari/537.36

Referer: https://twmts.quickbase.com/db/bhkhmzax6?a=dbpage&pageID=145
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8

an this as the response header: 这作为响应头：

Cache-Control: no-cache
Date: Mon, 10 Mar 2014 12:15:48 GMT
Content-Length: 0

No XML or JSON returned. 没有返回XML或JSON。 I know it has to besomething simple I am just not getting, but I have spent a lot of time tryig to determine what I am missing and other than not using the node.js, I can't figure it out. 我知道这一定很简单，我只是不明白，但是我花了很多时间tryig来确定我所缺少的东西，除了不使用node.js之外，我无法弄清楚。

Answer 1

The DocuSign sample code you've referenced uses Node.js modules, more specifically it uses request , async , and the fs module. 您引用的DocuSign示例代码使用Node.js模块，更具体地说，它使用request ， async和fs模块。 It looks like you've commented out the three lines where it imports the Node.js libraries that it needs: 您似乎已经注释了导入所需的Node.js库的三行：

//var     async = require("async"),     // async module
//        request = require("request"),     // request module
//      fs = require("fs");         // fs module

The require statement loads different modules, and when you comment out the above the code it has no idea what the async.waterfall function is since it's not declared anywhere. require语句加载不同的模块，并且当您注释掉上面的代码时，它不知道async.waterfall函数是什么，因为它没有在任何地方声明。 To resolve try un-commenting the above code so that's it's: 要解决该问题，请尝试取消注释上面的代码，结果如下：

var     async = require("async"),     // async module
        request = require("request"),     // request module
      fs = require("fs");         // fs module
