Another way to do it is to start a local HTTP server on your directory. On Ubuntu and MacOs with Python installed, it’s a one-liner. Go to the directory containing your web files, and : python -m SimpleHTTPServer Then connect to http://localhost:8000/index.html with any web browser to test your page.
What happens if the browser receives a redirect response to an ajax request? If the server sends a redirect (aka a 302 response plus a Location: header) the redirect is automatically followed by the browser. The response to the second request (assuming it also isn’t another redirect) is what is exposed to your program. In … Read more
I found a complete solution for this question. (I’ve tested this in Chrome 27 and Firefox 21). There are two things to know: Trigger ‘Save password’, and Restore the saved username/password 1. Trigger ‘Save password’: For Firefox 21, ‘Save password’ is triggered when it detects that there is a form containing input text field and … Read more
The reason for the error is the same origin policy. It only allows you to do XMLHTTPRequests to your own domain. See if you can use a JSONP callback instead: $.getJSON( ‘http://<url>/api.php?callback=?’, function ( data ) { alert ( data ); } );
$.post() is an abbreviated form of the $.ajax() structure. I usually prefer to use the $.ajax() structure because: It’s easier to see if I’ve missed anything I can more easily add additional params, such as asynch: false, When new to ajax I found it considerably easier to troubleshoot this structure In your case, you might … Read more
The onsuccess runs if ajax request itself was successful (i.e. there’s no network error, uncaught exception, etc), not if action method was successfully invoked. Given a <p:dialog widgetVar=”yourWidgetVarName”>, you could remove the onsuccess and replace it by PrimeFaces RequestContext#execute() inside saveMethod(): if (success) { RequestContext.getCurrentInstance().execute(“PF(‘yourWidgetVarName’).hide()”); } Note: PF() was introduced in PrimeFaces 4.0. In older … Read more
In your action method, return Json(object) to return JSON to your page. public ActionResult SomeActionMethod() { return Json(new {foo=”bar”, baz=”Blech”}); } Then just call the action method using Ajax. You could use one of the helper methods from the ViewPage such as <%= Ajax.ActionLink(“SomeActionMethod”, new AjaxOptions {OnSuccess=”somemethod”}) %> SomeMethod would be a javascript method that … Read more
The jquery ajax method returns a XMLHttpRequest object. You can use this object to cancel the request. The XMLHttpRequest has a abort method, which cancels the request, but if the request has already been sent to the server then the server will process the request even if we abort the request but the client will … Read more
I spent some time being confused as to the purpose of the preflight request but I think I’ve got it now. The key insight is that preflight requests are not a security thing. Rather, they’re a not-changing-the-rules thing. Preflight requests have nothing to do with security, and they have no bearing on applications that are … Read more
The cause of the problem can be understood by considering the following facts: When JSF validation succeeds for a particular input component during the validations phase, then the submitted value is set to null and the validated value is set as local value of the input component. When JSF validation fails for a particular input … Read more
