xmlhttprequest

问题 I'm building a web app with Django. I have a bunch of API calls in Javascript via Ajax (jQuery v1.8.3).

问题 Once in a while, my Ajax calls (via JQuery 1.8) in my application are stuck with status "pending" for a long time (sometimes up to 17 minutes). I've googled it and all possible solutions didn't work: I have no ad blocker installed. I've disabled the "predict network actions to improve page load performance" flag in Chrome. I've also added a query string to the Ajax call to make it unique (to disable any Chrome cache locking). Do you have a any idea how to solve this? Thanks. In the example

问题 i'm issuing a request using MSXML's XmlHttpRequest object: IXMLHttpRequest http = new XmlHttpRequest(); http.open("GET", "http://www.bankofcanada.ca/stat/fx-xml.xml", False, "", ""); http.send(); And the send succeeds, and i get my xml data.

问题 I'm relatively new to Ajax and was just tasked with this cross-domain call. We have a text box on our web page that a user will use to preform a search of company names. By clicking a button next to the text box, the Ajax call will be requested. Unfortunately the web service is located in a separate domain, so this is naturally causing issues. Below is my best attempt at making this work. I should also note, the purpose of this call is to return the results in an XML format, which will be

问题 I am supporting a Classic ASP application that connects to a payment gateway via HTTPS. Up until recently there have been no issues.
