xmlhttprequest

问题 I'm running GM_xmlhttpRequest (in a Greasemonkey script) and storing the responseText into a newly created HTML element: var responseHTML = document.createElement('HTML'); ... onload: function() { responseHTML.innerHTML = response.responseText; } And then I am trying to find an element in responseHTML : console.log(responseHTML.getElementsByTagName('div')); console.log(responseHTML.getElementById('result_0')); The first works fine, but not the second. Any ideas? 回答1: getElementById is not a

问题 I am trying to build a Chrome Extension that uses the BOX api. I am able to authentificate and enable access for the app, and then I extract and store the access token from the URL. The next step would be to upload a file to box, and I am trying to use the code they provided on the website with small modifications: //file - a csv file I created before var uploadUrl = 'https://upload.box.com/api/2.0/files/General'; // The Box OAuth 2 Header. Add your access token. var headers = { Authorization

问题 I would like to send a POST asynchronously from client side (JavaScript) to server side (ASP.Net) with 2 parameters: numeric and long formated string. I understand the long formated string must have encodeURIComponent() on it befor passing it. My trouble is I want to embed the long encoded string in body request and later open it from C# on server side. Please, can you help me? I'm messing too much with ajax, xhr, Request.QueryString[], Request.Form[], .... 回答1: First, create an HTTPHandler:

问题 I made a 'voting' API for a topsite for the sites registered to use. <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script type="text/javascript"> var id = 1; $(document).ready(function(){ $.getJSON("http://mysite.com/index.php?page=vote", { id: id, hasVoted: 'unknown' }, function(data) { if(data == 2) { window.location.replace("http://mysite.com/index.php?page=vote&id=" + id); } }); }); </script> Basically, I give the user's their ID and then they

问题 I have a xmlhttprequest which uploads the file and I am trying to receive it in my node-express server. but for some reason I am not able to retrieve the file content in the server. Not sure where I am missing it. app.post('/api/uploadfiles', function(req, res) { console.log("apicalled"); console.log(req); console.log(req.body); console.log(req.files); console.log(JSON.stringify(req.files)); }); 回答1: In order for you to see the files, you will need to add another middleware that parses multi

问题 I've done a lot of times before, so I'm honestly confused why this is failing to pass anything. I've tried printing results (script gets a response and prints the file). function submit_form_inpage(path, data, watchForChange){ alert(data); watchForChange = watchForChange || false; var request = new XMLHttpRequest(); request.open('POST', path, true); request.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8'); if (watchForChange == true) { request

问题 I'm trying to learn to use $http.get requests in AngularJS for a web app that I am writing. I have a locally hosted server that has some API that I have written. When I try to run my Angular page I can see in my server's console that the GET request has been made however nothing loads in the browser.

问题 as the synchronous XMLHttpRequest is being deprecated, I'm wondering if there is some kind of alternative to simulate similar behaviour as non-blocking asynchronous XMLHttpRequests are not suitable for some cases. I'm talking in particular about a case where I need to send a Post Request to the server, when an user clicks a hyperlink. Using PreventDefault is not an option here. With Synchronous XMLHttpRequest I can use an OnClick event, send the Request, and once it's done the browser
