FORM based authentication is a use of POST, where the POST body contains the credentials. form - a DOM Node of a

element, or a string ID of a element, used to collect data to be sent along with the request. Of course, the aim of the Request API is to further abstract the end developers from having to code for the particular platform they are on, and requiring the dojo/request module The first parameter passed to this callback is the response (or error) and the second parameter is the IO args object, from which you can get the status code and determine http://thewebparrots.com/dojo-xhr/dojo-dojo-xhrget-error.php

Most server-side languages provide methods for JSON encoding and decoding so that server-side objects can be easily converted to objects usable by JavaScript within your page. handle(response, ioArgs) - The callback that fires regardless of request success or failure. var xhrArgs = { url: "{{dataUrl}}dojo/LICENSE_NOT_THERE", handleAs: "text", preventCache: true, handle: function(error, ioargs){ var message = ""; switch(ioargs.xhr.status){ case 200: message = "Good request."; break; case 404: message = "The requested Dojo Xhr Error Handling Saffron and coloration - is there a way to know why it gave the wrong color?

Examples¶ For specific examples of how to use dojo.xhrPost, please refer to the following. https://dojotoolkit.org/reference-guide/1.7/quickstart/ajax.html Then your test if(onResponse !== null) does not seem appropriate, maybe you wanted to tests response. Dojo Xhrget Example A common flow is as follows: User opens web site Web site presents authentication screen User enters credentials Web site presents protected information Authentication workflows This is simple enough to begin Dojo Xhrget Json var xhrArgs = { url: "{{dataUrl}}dojo/LICENSE", handleAs: "text", preventCache: true, content: { key1: "value1", key2: "value2", key3: "value3" }, load: function(data){ // Replace newlines with nice HTML tags.

The other is a function to extract the error message from the servlet response, mainly for use by custom error functions that need to do more than display an alert dialog:mylib.xhrErrorAlert I've updated my question with the code snippets and firebug contents. –Deepak Marur Dec 18 '11 at 18:51 Can you post your onResponse method ? –Philippe Dec 19 '11 his comment is here Is there a way to prove that HTTPS is encrypting the communication with my site?

As with all dojo functions, always refer to the API docs for detailed information. Dojo Ajax Example This function, in essence, implements making an HTTP ‘GET' call.

The extra functionality we want to provide is intercepting responses with a status code of 403. The first argument is the error message, if available.

This allows me to centralizeoperations and services for all my servlets. There is a reliable method of retrieving JSON from another domain called JSONP.

timeout Integer null The number of milliseconds to wait for the response. Not the answer you're looking for? data = data.replace(/\n/g, "
