xmlhttprequest

问题 I am stuck in the middle of a bug. I began to use BrowserStack to validate my current project against Windows IE and EDGE and I got a particular issue with IE 11. I first got an issue that I solved which was that FormData did not have any .get() methods, and I used the NPM formdata-polyfill for that. I am working on a native JS login form, using FormData and XMLHTTPRequest, and it seems that the AJAX call is not firing at all. When clicking on the submit button, instead of sending to my

问题 I want to set a timeout value so that if the server does not respond in that particular time frame then UI should move ahead and not wait for response. I have used the below syntax so far but the UI gets hanged waiting for response. How can I specify a callback to reset the values and inform UI that no longer needed to wait. q.promise(function(resolve, reject) { d3.xhr(my_url) .header('Content-Type', 'text/xml') .timeout(2000) .send(this.my_method, my_xmlData, function(error, data) { }) }); I

问题 I'm trying to do a form post from another site that is not mine, but I am not able ta give error. There on the site the post is mounted like this: <a href="javascript:document.result.submit()" class="lnk-more">Veja o resultado da enquete anterior »</a> <br /><br /> <form name="result" action="http://enquete.terra.com.br/enquete.cgi" method="post"> <input type="hidden" name="id_enquete" value="144143"> <input type="hidden" name="opcao" value="0"> </form> And I'm riding in the asp script to

问题 I'm doing a web where I heavily use AJAX requests to a XML service. In fact, my web is a front-end with almost no server whatsoever and uses AJAX to communicate with the back-end. Everything was going fine (I developed and tested in Ubuntu 9.04 and Firefox 3.0 as a browser). One day I decided to see how my web did in IE8... horror! Nothing was working as it marvelously did in Firefox. To be more specific, the Request.HTML's were not working. As I said, my web relied heavily on that, so

问题 So I've been trying to access the twitch.tv api but every time i go to make a request i keep on getting the error: "XMLHttpRequest cannot load https://api.twitch.tv/kraken/streams/normalice. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8080' is therefore not allowed access." I'm currently using the live-server package during the development process other wise I'm just using html, css, javascript. Here is my javascript: var req = new

问题 I'm having problems with catching 403 from $.ajax promise in jQuery v1.x. The same code $.ajax({ dataType: 'jsonp', url: 'http://www.checkupdown.com/accounts/grpb/B1394343/', type: 'GET' }).then(function () { console.log('success', arguments) }, function () { console.log('error', arguments) }); rejects the promise as expected in jQuery v2.x but logs nothing in jQuery v1.x (the promise has readyState == 1 ). The examples use 2.1.3 and 1.11.3 jQuery versions respectively. Why exactly does this

问题 I tried to do a simple AJAX request on http://localhost:8080/ and I get an error right away when using IE 11. I don't think IE is even trying to send anything. Did somebody meet this issue? Here is a fiddle showing this behavior, html: <button id='btn1'>launch</button> onLoad: var xhr,btn=document.getElementById('btn1'); btn.onclick=onButton; var onReadyState=function(){ console.log('ready state:'+_xhr.readyState); if(xhr.readyState===4){ console.log('status:'+_xhr.status); } } function

问题 I have a Jquery web site that needed to be upgraded to provide Local Storage caching capability, Target was making every Ajax request checks first if there is a cached response HTML, then it will NOT call the server side, but gets data from cache instead. Everything going OK with caching and displaying data from cache and so on.. My problem appeared when applying my caching core to sites that heavily depending on XML HTTP Response Headers; It Appeared that when I try to cache the

My code is var xhr = new XMLHttpRequest(); xhr.upload.onprogress = function(e){ if (e.lengthComputable){ self._loaded[id] = e.loaded; self._options.onProgress(id, name, e.loaded, e.total); } }; xhr.onreadystatechange = function(){ if (xhr.readyState == 4){ self._onComplete(id, xhr); } }; // build query string params = params || {}; params['qqfile'] = name; var queryString = qq.obj2url(params, this._options
