On slow network previous Ajax request gets cancelled by the subsequent
javascript,ajax,xmlhttprequest
You should use a local variable to hold the XMLHttpRequest. Since you're using a global variable, the callback function always refers to the second AJAX request that was sent. So change: xhr = new XMLHttpRequest(); to: var xhr = new XMLHttpRequest(); Then each callback funtion will be a closure that...

XHR OnLoad Promise blocking other OnLoad callbacks
javascript,asynchronous,xmlhttprequest,es6-promise
I think what you're asking here (with this horrible busy-waiting sleep() function that no-one should ever use in real code) is how come all the .then() functions take precedence over the onload events in the JS event loop? They do, and it's because promises run on a micro-task queue, which...

CORS issue with asynchronously loaded JavaScript through dynamically created script tags
javascript,html,ajax,xmlhttprequest,cors

Not able to get Request-scoped attribute in Action through XMLHttpRequest
jquery,ajax,struts2,http-headers,xmlhttprequest
I guess the problem is that the AJAX call is ignoring your request-scoped attributes, since it creates a brand new XMLHttpRequest instead of a classic HttpRequest.

Why does the jquery ajax documentation mean when it says “For backward compatibility with XMLHttpRequest”

Why is this "backwards compatibility"? Because a long time ago, jQuery's ajax method returned the XMLHttpRequest object directly.

when will callback for synchronous xmlHttpRequest calls get executed?
If the XHR is synchronous then the callbacks are executed before .send() returns. In other words before blablabla(). Browser DOM updates are asynchronous. Or rather, the redraws are asynchronous (DOM update/reflow can at times be synchronous but it won't draw to screen, just update data structures). So, even if...

So before submitting jQueryAJAX post method, dataParam needs to be converted as URLString by using $.param method. var fomrValues = $("form[name="...
HTTP Post Rails 4 Issue
rest,ruby-on-rails-4,xmlhttprequest,http-post,net-http
My guess is that you have configured your email parsing service to POST the data to a URL which is only accessible from your local system, for instance a pow.cx style ".dev" URL. The reason this works using your test utility is I'm assuming the test client is also on...

When Promisifying a XMLHttpRequest, how to catch a throw Error
javascript,xmlhttprequest,promise

JavaScript: XMLHttpRequest() from Firefox addon to get zip
javascript,firefox,xmlhttprequest,firefox-addon,zip
I'm almost dont, I'm just stuck on figuring out how to use the asynchronus zip.js module. You can use nsIZipWriter and nsIZipReader like the linked addon does from my comment. But I think async is just better so I'm working on that: https://github.com/Noitidart/AysncZip/blob/master/bootstrap.js Install the addon, click on the toolbar...
Scrapy crawler not processing XHR Request
python,web-scraping,xmlhttprequest,scrapy,scrape
If you inspect the "Load More" button, you would not find any indication of how the link to load more reviews is constructed. The idea behind is rather easy - the numbers after http://www.t3.com/more/reviews/latest/ suspiciously look like a timestamp of the last loaded article. Here is how you can get...

HTTP Post Request to web service . ERROR : Index was outside the bounds of the array
c#,multithreading,.net-4.0,xmlhttprequest
It happens because the expression () => function(files[x],p) is evaluated after the first inner loop is complete, and x is incremented in this loop. So you always get the out-of-range value of x=len. To solve this, you need to declare another local variable and assign value of x to it,...
Will a cross site XMLHTTPRequest ever re-use credentials?
javascript,xmlhttprequest,csrf,http-basic-authentication
As long as you don't have the Access-Control-Allow-Credentials response header set, it will not allow authorisation for API requests that read data (the request will still be made, although the response cannot be read by the other domain due to the Same Origin Policy). You still should implement CSRF protection...
