xmlhttprequest

问题 For one of our ajax request (with a .json response) some of our clients have complained that they are seeing a "File Download" prompt asking the user to download the .json response. I am baffled because considering that this is an xhr response, this should never happen. Has anyone seen this? Thanks 回答1: For people who are using ASP MVC and have the same problem with IE, use this when returning your response: return Json(result, "text/plain"); Edit: the standard type is: "application/json",

问题 Upon reading stuffs about POST and get methods here there is a statement like " when used post method it uses HTTP request Body . What Does it mean " HTTP request body".? 回答1: HTTP Body Data is the data bytes transmitted in an HTTP transaction message immediately following the headers if there is any (in the case of HTTP/0.9 no headers are transmitted). Most HTTP requests are GET requests without bodies. However, simulating requests with bodies is important to properly stress the proxy code

问题 I was reading about CORS and I think the implementation is both simple and effective. However, unless I'm missing something, I think there's a big part missing from the spec. As I understand, it's the foreign site that decides, based on the origin of the request (and optionally including credentials), whether to allow access to its resources. This is fine. But what if malicious code on the page wants to POST a user's sensitive information to a foreign site? The foreign site is obviously going

问题 First I have my data encoded in the json_encode function. Looks like this for example: {"test":"test value"} What I want to do is make test into a javascript variable where it can hold the data of "test value". 回答1: index.php (use json_encode here): <?php $foo = array('test' => 'test value'); echo json_encode($foo); ?> example.html <script type="text/javascript"> $.get('index.php', function(response) { alert(response['test']); // this will alert "test value" }, 'json'); </script> EDIT1 :

问题 I am using the following code to read an external xml file : if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","myxmlfile.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; But the above code seems to work only on Firefox and not on Chrome/IE/Opera. In Chrome I am getting an error in Console as cross domain access not allowed, but my

问题 Could please anybody who has experiences with processing post xmlHttpRequests with Spring DispatcherPortlet, tell me what is the best way to do it ? I'm using YUI io module and Jackson Object Mapper as an example : @ResourceMapping(value="stuff") public void method(ResourceResponse response){ Person person = new Person(); person.setWeight(150); ObjectMapper mapper = new ObjectMapper(); try{ mapper.writeValue(response.getWriter(), person); } ... } Ajax: function() { var A = AUI(); A.io("

问题 I know that there's a bunch of questions about the "not allowed by Access-Control-Allow-Origin." error. But I've tried some of them without success. :( Some appointments: I'm trying to build a dev-tools-tab extension I can touch flickr API like the example shows I can't reach localhost Already tried several permission wildcards http://localhost/ http://*/ *://*/ Already tried pack'd and unpack'd extensions currently, manifest.json has "version": "0.0.1", "manifest_version": 2, "devtools_page"

问题 I have a problem with my chat script in Google Chrome. Sometimes the responsetext is empty until you reload the page, but sometimes it's working well. It opens a xmlhttp connection every second and if the first good the ones after that also good. In Firefox it's always good. var url = "text.php"; xmlHttp.open("GET", url, true); xmlHttp.onreadystatechange = myfunc; xmlHttp.send(null); function myfunc() { if (xmlHttp.readyState == 4 || xmlHttp.readyState == "complete") { var msg = xmlHttp

问题 In the following SSCCE, I have a string which contains the HTML for three div s. I add a style="display:none;" attribute to all the div s except the first one. I add a button to all the div s except the last one, and add a JS onclick event listener, which should change the current div 's style property to style="display:none;" (current div 's id attribute passed to the JS function.) and the next div 's (it's id is also passed to the JS function) style property to style="display:block;" I add
