关于Jquery 查询 JSON_course

我是做一个地区的三级联动。。。 <script type="text/javascript" src="/images/js/diregion.js"></script> 是我将地区数据表里面的内容查询出来生成的JSON字串  ``` <script type="text/javascript" src="/images/js/jquery-1.9.1.js"></script> <script type="text/javascript" src="/images/js/jquery.min.js"></script> <script type="text/javascript" src="/images/js/diregion.js"></script> <script type="text/javascript" src="/images/js/linq.js"></script> <script type="text/javascript" src="/images/js/linq.min.js"></script> <script type="text/javascript"> $(document).ready(function () { var queryResult; queryResult = Enumerable.From(dicregion).Where("$.Grade == 1").Select("$.id + ','+ $.description").ToArray(); var str = 'aaa'; for (num in queryResult) { var result = queryResult[num].split(','); var tr = "<tr><td>" + num +"</td> <td>" + result[0] + " </td> <td>" + result[1]+ "</td></tr>"; $(".table").append(tr); } }); </script> ``` 通过以上处理后 <table class="table"> <tr> <td>11</td> <td>测试</td> <td>值</td> </tr> </table> 没有任何变化。请问是哪里错了吗？ JSON字串太长了，只上一条信息 ``` var dicregion = [{ 'Id': '10', 'Grade': '1', 'ParentId': '', 'Description': '北京市', 'DescriptionEng': '北京市', 'OrderNo': '1', 'FullName': '北京市', 'MapBarName': '北京市', 'Lng': '116.38705', 'Lat': '39.90771', 'Abbr': '北京', 'AreaCode': '010', 'IsUsed': 'True', 'IsDel': 'False', 'FirstLetter': 'B' }, ```

Javascript / jquery 通过 POST 和 JSON 数据下载文件_course

<div class="post-text" itemprop="text"> <p>I have a jquery-based single-page webapp. It communicates with a RESTful web service via AJAX calls. </p> <p>I'm trying to accomplish the following:</p> <ol> <li>Submit a POST that contains JSON data to a REST url.</li> <li>If the request specifies a JSON response, then JSON is returned.</li> <li>If the request specifies a PDF/XLS/etc response, then a downloadable binary is returned.</li> </ol> <p>I have 1 &amp; 2 working now, and the client jquery app displays the returned data in the web page by creating DOM elements based on the JSON data. I also have #3 working from the web-service point of view, meaning it will create and return a binary file if given the correct JSON parameters. But I'm unsure the best way to deal with #3 in the client javascript code.</p> <p>Is it possible to get a downloadable file back from an ajax call like this? How do I get the browser to download and save the file?</p> <pre><code>$.ajax({ type: "POST", url: "/services/test", contentType: "application/json", data: JSON.stringify({category: 42, sort: 3, type: "pdf"}), dataType: "json", success: function(json, status){ if (status != "success") { log("Error loading data"); return; } log("Data loaded!"); }, error: function(result, status, err) { log("Error loading data"); return; } }); </code></pre> <p>The server responds with the following headers:</p> <pre><code>Content-Disposition:attachment; filename=export-1282022272283.pdf Content-Length:5120 Content-Type:application/pdf Server:Jetty(6.1.11) </code></pre> <p>Another idea is to generate the PDF and store it on the server and return JSON that includes a URL to the file. Then, issue another call in the ajax success handler to do something like the following:</p> <pre><code>success: function(json,status) { window.location.href = json.url; } </code></pre> <p>But doing that means I would need to make more than one call to the server, and my server would need to build downloadable files, store them somewhere, then periodically clean up that storage area.</p> <p>There must be a simpler way to accomplish this. Ideas?</p> <hr> <p>EDIT: After reviewing the docs for $.ajax, I see that the response dataType can only be one of <code>xml, html, script, json, jsonp, text</code>, so I'm guessing there is no way to directly download a file using an ajax request, unless I embed the binary file in using Data URI scheme as suggested in the @VinayC answer (which is not something I want to do).</p> <p>So I guess my options are:</p> <ol> <li><p>Not use ajax and instead submit a form post and embed my JSON data into the form values. Would probably need to mess with hidden iframes and such.</p></li> <li><p>Not use ajax and instead convert my JSON data into a query string to build a standard GET request and set window.location.href to this URL. May need to use event.preventDefault() in my click handler to keep browser from changing from the application URL.</p></li> <li><p>Use my other idea above, but enhanced with suggestions from the @naikus answer. Submit AJAX request with some parameter that lets web-service know this is being called via an ajax call. If the web service is called from an ajax call, simply return JSON with a URL to the generated resource. If the resource is called directly, then return the actual binary file.</p></li> </ol> <p>The more I think about it, the more I like the last option. This way I can get information back about the request (time to generate, size of file, error messages, etc.) and I can act on that information before starting the download. The downside is extra file management on the server.</p> <p>Any other ways to accomplish this? Any pros/cons to these methods I should be aware of?</p> </div> <p>转载于:https://stackoverflow.com/questions/3499597/javascript-jquery-to-download-file-via-post-with-json-data</p>

I am getting the scores by doing a HTTP GET request. The problem is that the scores output to the Golang console in JSON Format. I want to display the scores onto the actual website. How could I call my golang function in the Frontend in order to do this? The frontend is written in HTML/Javascript/JQuery.</p> <p>This is my Golang Function that does the HTTP Request to SwaggerUI and outputs to the Golang Console:</p> <pre><code>func scoresPage(res http.ResponseWriter, req *http.Request) { //Connecting to SwaggerUI API to get Scores from Azure for UWP Application req, err := http.NewRequest("GET", os.ExpandEnv("https://brainworksappservice.azurewebsites.net/tables/TodoItem?$select=score"), nil) if err != nil { log.Fatal(err) } //You have to specify these headers req.Header.Set("Accept", "application/json") //If you do not specify what version your API is, you cannot receive the JSON req.Header.Set("Zumo-Api-Version", "2.0.0") //Do the request resp, err := http.DefaultClient.Do(req) //Error if the request cannot be done if err != nil { log.Fatal(err) } //You need to close the Body everytime, as if you don't you could leak information defer resp.Body.Close() //Read all of the information from the body body, err := ioutil.ReadAll(resp.Body) //Error if the info cannot be read if err != nil { log.Fatal(err) } //Write the JSON to the standard output (the Console) _, err = os.Stdout.Write(body) //Error if the info cannot be output to the console if err != nil { log.Fatal(err) } http.ServeFile(res, req, "Scores.html") } ` </code></pre> <p>This is the main Function which serves up the website and handles the scores page:</p> <pre><code>func main() { http.HandleFunc("/scores", scoresPage) //serve on the port 8000 forever http.ListenAndServe(":8000", nil) } </code></pre> </div>
