The 500 (internal server error) means something went wrong on the server’s side. It could be several things, but I would start by verifying that the URL and parameters are correct. Also, make sure that whatever handles the request is expecting the request as a GET and not a POST. One useful way to learn … Read more
TLDR; If you’re looking for a way to control the contents of an <iframe> via React in a de-facto canonical way, Portals are the way to go. And as with all things Portal: Once you establish a reference to an existing and mounted DOM node (in this case that would be the contentWindow of a … Read more
Consider the example: Option Explicit Sub Test() Dim strExportURL As String Dim strFormData As Variant Dim strContent As String Dim arrRespBody() As Byte ‘ build exportURL parameter strExportURL = Join(Array( _ “permitIdentifier=”, _ “accountID=”, _ “form=accountAll”, _ “installationIdentifier=”, _ “complianceStatus=”, _ “account.registryCodes=CY”, _ “primaryAuthRep=”, _ “searchType=account”, _ “identifierInReg=”, _ “mainActivityType=”, _ “buttonAction=”, _ “account.registryCode=”, _ … Read more
The innerHTML property has some problems in IE when trying to add or update form elements, the workaround is to create a div and set the innerHtml property on that before appending to the DOM: var newdiv = document.createElement(“div”); newdiv.innerHTML = xmlhttp.responseText; var container = document.getElementById(id); container.appendChild(newdiv);
This range-request works fine for me: http://jsfiddle.net/QFdU4/ var xhr = new XMLHttpRequest; xhr.onreadystatechange = function () { if (xhr.readyState != 4) { return; } alert(xhr.status); }; xhr.open(‘GET’, ‘http://fiddle.jshell.net/img/logo.png’, true); xhr.setRequestHeader(‘Range’, ‘bytes=100-200’); // the bytes (incl.) you request xhr.send(null); You have to make sure that the server allows range requests, though. You can test it with … Read more
Use CreateObject(“MSXML2.ServerXMLHTTP.6.0”) The standard request fired from a local machine forbids access to sites that aren’t trusted by IE. MSXML2.ServerXMLHTTP.6.0 is the server-side object, that doesn’t perform those checks.
Edit: See the second code option below (it is tested and works). The first one has some limitations. Since you can’t modify any of those functions, it appears you have to go after the XMLHttpRequest prototype. Here’s one idea (untested, but you can see the direction): (function() { var open = XMLHttpRequest.prototype.open; XMLHttpRequest.prototype.open = function(method, … Read more
If the url you provide is located externally to your server, and the server has not allowed you to send requests, you have permission problems. You cannot access data from another server with a XMLHttpRequest, without the server explicitly allowing you to do so. Update: Realizing this is now visible as an answer on Google, … Read more
The current state of standardizing the XMLHttpRequest API does only restrict the access to the Set-Cookie and Set-Cookie2 header fields: client.getAllResponseHeaders() Returns all headers from the response, with the exception of those whose field name is Set-Cookie or Set-Cookie2. Any other header field should be returned. But as you’re doing a cross-origin request, the browser … Read more
You have a few different mistakes. First, $.get doesn’t return the return value of the callback function. It returns the XHR object. Second, the get function isn’t synchronous, it’s asynchronous so showGetResult will likely return before get completes. Third, you can’t return something from inside the callback to the outer scope. You can, however, bind … Read more
