In your config, DI `$httpProvider` and then set withCredentials to true:

	.config(function ($httpProvider) {
		$httpProvider.defaults.withCredentials = true;
		//rest of route code
    })

Info on angularjs withCredentials: [http://docs.angularjs.org/api/ng.$http][1]

    $http.get(&quot;URL&quot;, { withCredentials: true })
      .success(function(data, status, headers, config) {})
      .error(function(data, status, headers, config) {});

Another thing to keep in mind: You need to **have 3rd party cookies enabled**. If you have it globally disabled in Chrome, click on the &quot;i&quot;-Symbol to the left of the domain name, then cookies, then &quot;blocked&quot; and unblock the target domain.

how is possible to make a box around text in matplotlib? 
I have text on three different lines and in three different colors:

     ax.text(2,1, &#39;alpha&#39;, color=&#39;red&#39;)
     ax.text(2,2, &#39;beta&#39;, color=&#39;cyan&#39;)
     ax.text(2,3, &#39;epsilon&#39;, color=&#39;black&#39;)

I saw the tutorial http://matplotlib.org/users/recipes.html (last example) but I can&#39;t solve the problem. 
Thanks in advance.

Box around text in matplotlib

I&#39;ve often wanted to sort strings with numbers in them so that, when sorting e.g.  `abc_2, abc_1, abc_10` the result is `abc_1, abc_2, abc_10`. Every sort mechanism I&#39;ve seen sorts as `abc_1, abc_10, abc_2`, that is character by character from the left. 

Is there any efficient way to sort to get the result I want? The idea of looking at every character, determining if it&#39;s a numeral, building a substring out of subsequent numerals and sorting on that as a number is too appalling to contemplate in `bash`.

Has no bearded *nix guru implemented an alternative version of `sort` with a `--sensible_numerical` option?

We are working on a RESTful Webservice with AngularJS and Java Servlets.
When the user logs in, our backend sends a &quot;Set-Cookie&quot; header to the frontend. In Angular we access the header via `$cookies` (ngCookie - module) and set it.
![enter image description here][1]


Now that the user is logged in he can for example delete some stuff. Therefore the frontend sends a GET request to the backend. Because we work on different domains we need to set some CORS Headers and Angular does an OPTIONS request before the actual GET request:

**OPTIONS request:**
![OPTIONS request][2]

**GET request**
![GET request][3]

We do this in Angular via $http module, but it just won&#39;t send the cookie, containing `JSESSIONID`.

$http doesn&#39;t send cookie in Requests

We are working on a RESTful Webservice with AngularJS and Java Servlets.
When the user logs in, our backend sends a "Set-Cookie" header to the frontend. In Angular we access the header via <code>$cookies</code> (ngCookie - module) and set it.

I would like to read a file and convert it into a base64 encoded string using the FileReader object. Here&#39;s the code I use :
&lt;pre&gt;

    var reader = new FileReader();
    reader.onloadend = function(evt) {  
        // file is loaded
        result_base64 = evt.target.result; 
    };
    reader.readAsDataURL(file); 

  
&lt;/pre&gt;

But in this case, I get the result of the conversion in the event handler (onLoadEnd event). I would like a synchronous method. Is there a way the &quot;readAsDataURL&quot; method can return directly the value of the &#39;result_base64&#39; variable ?

I have a div that will have this CSS:

&lt;!-- language: lang-css --&gt;

    #some_kind_of_popup
    {
        position: fixed;
        top: 100px;
        min-height: 300px;
        width: 90%;
        max-width: 900px;
    }

Now, how can i make this div centered? I can use `margin-left: -450px; left: 50%;` but this will only work when the screen is &gt; 900 pixels. After that (when the window is &lt; 900 pixels), it will no longer be centered. 

I can of course do this with some kind of js, but is there a &quot;more correct&quot; of doing this with CSS?

I have this simple scenario:  

Input element which value is changed by jQuery&#39;s val() method.

I am trying to update the angular model with the value that jQuery set. I tried to write a simple directive, but it&#39;s not doing what I want. 

Here&#39;s the directive:

    var myApp = angular.module(&#39;myApp&#39;, []);
    myApp.directive(&#39;testChange&#39;, function() {
        return function(scope, element, attrs) {        
            element.bind(&#39;change&#39;, function() {
                console.log(&#39;value changed&#39;);
            })
        }
    })

this is the jQuery part:  

    $(function(){
        $(&#39;button&#39;).click(function(){
            $(&#39;input&#39;).val(&#39;xxx&#39;);
        })
    })

and html:

    &lt;div ng-app=&quot;myApp&quot;&gt;
        &lt;div ng-controller=&quot;MyCtrl&quot;&gt;
            &lt;input test-change ng-model=&quot;foo&quot; /&gt;
            &lt;span&gt;{{foo}}&lt;/span&gt;
        &lt;/div&gt;
    &lt;/div&gt;

    &lt;button&gt;clickme&lt;/button&gt;

Here is the fiddle with my try:

&gt; 10 $digest() iterations reached. Aborting!

There is a lot of supporting text in the sense of &quot;Watchers fired in the last 5 iterations: &quot;, etc., but a lot of this text is Javascript code from various functions.  Are there rules of thumb for diagnosing this problem?  Is it a problem that can ALWAYS be mitigated, or are there applications complex enough that this issue should be treated as just a warning?

I&#39;m trying to create an iOS 7 style frosted look with HTML5, CSS3 and JavaScript which can work on webkit browsers.

Technically, given the following HTML:

    &lt;style&gt;
      #partial-overlay {
        width: 100%;
        height: 20px;
        background: rgba(255, 255, 255, .2); /* TODO frost */
        position: fixed;
        top: 0;
        left: 0;
      }
    &lt;/style&gt;
    &lt;div id=&quot;main-view&quot;&gt;
      &lt;div style=&quot;width: 50px; height: 50px; background: #f00&quot;&gt;&lt;/div&gt;
      To my left is a red box&lt;br&gt;
      Now there is just text&lt;br&gt;
      Text that goes on for a few pixels &lt;br&gt;
      or even more
    &lt;/div&gt;
    &lt;div id=&quot;partial-overlay&quot;&gt;
      Here is some content
    &lt;/div&gt;

I&#39;d like to apply something like a `-webkit-filter: blur(5px)` to the first 20px horizontally of `#main-view`.

If the CSS was modified to be `#partial-overlay { width: 20px; height: 100%; ...}` then I&#39;d need to apply the `-webkit-filter: blur(5px)` to the first 20px vertically.

The obvious solution is to use javascript to make a clone of the `#main-view`, set `overflow: hidden` and then change the width/height as appropriate but that seems to me hard to generalize to more complex pages/CSS structures.

Is there a better way to achieve this with minimal performance hit and maximal generalizability?

    &lt;/video&gt;

starts playing automatically once the page is loaded in FireFox but cannot do autoplay in Webkit based browsers. This only happened on some random pages. So far I was unable to find the cause. I suspect some unclosed tags or extensive JS created by CMS editors.

I would like to check server-side if a request to my php page is an ajax request or not.

I saw two ways to do this:

First way: sending a `GET` parameter in the request which tells the page that this is an AJAX request (=`mypage.php?ajax`)

mypage.php:

    if(isset($_GET[&#39;ajax&#39;])) {
        //this is an ajax request, process data here.
    }

Second way: set a header to the `xmlHttpRequest`:

client-side js:

    
    xmlHttpRequestObject.open(“GET”,url,true);
    xmlHttpRequestObject.setRequestHeader(&#39;X-Requested-With&#39;, &#39;XMLHttpRequest&#39;);

mypage.php:

    if (!empty($_SERVER[&#39;HTTP_X_REQUESTED_WITH&#39;]) &amp;&amp; strtolower($_SERVER[&#39;HTTP_X_REQUESTED_WITH&#39;]) == &#39;xmlhttprequest&#39; ) {
        //request is ajax
    }

&lt;hr&gt;

The fact is, those two ways of doing it can easily be hacked, so it&#39;s not secure to check if i get an AJAX request like this.

How can i check if i&#39;m receiving an AJAX request?

How to check if the request is an AJAX request with PHP

In plain javascript is very simple: need just to attach the callback to `{XMLHTTPRequest}.onprogress`

    var xhr = new XMLHttpRequest();
    
    xhr.onprogress = function(e){
        if (e.lengthComputable)
            var percent = (e.loaded / e.total) * 100;
    };
 
    xhr.open(&#39;GET&#39;, &#39;http://www...&#39;, true);
    xhr.onreadystatechange = function() {
        ...
    };
    xhr.send(null);

but I&#39;m doing an ajax site that download html data with JQuery (`$.get()` or `$.ajax()`) and I was wondering which is the best way to get the progress of a request in order to display it with a little progress bar but curiously, I&#39;m not finding anything usefull in JQuery documentation...



What is the cleanest way to get the progress of JQuery ajax request?

I&#39;m trying to detect when an XMLHttpRequest() fails due to a Cross Origin Error as opposed to a bad request.  For example:

		ajaxObj=new XMLHttpRequest()
		ajaxObj.open(&quot;GET&quot;, url, true); 
		ajaxObj.send(null);

Consider 4 cases for url:

&lt;b&gt;Case 1:&lt;/b&gt; url is a valid address where access-control-allow-origin is properly set

 - Example: `http://192.168.8.35` where I have a server with `Access-Control-Allow-Origin: *` set in the header
 - This is easy to detect as ajaxObj.readyState==4 and ajaxObj.status==200

&lt;b&gt;Case 2:&lt;/b&gt; url is an invalid address at an existing server

 - Example: `http://xyz.google.com` where the server responds but it is not a valid request
 - This results in ajaxObj.readyState==4 and ajaxObj.status==0

&lt;b&gt;Case 3:&lt;/b&gt; url is to a non-existing server ip address

 - Example: `http://192.168.8.6` on my local network where there is nothing to respond
 - This results in ajaxObj.readyState==4 and ajaxObj.status==0

&lt;b&gt;Case 4:&lt;/b&gt; url is a valid address where access-control-allow-origin is &lt;b&gt;NOT&lt;/b&gt; set

 - Example: `http://192.168.8.247` where I have a server &lt;b&gt;without&lt;/b&gt; `Access-Control-Allow-Origin: *` set in the header
 - This results in ajaxObj.readyState==4 and ajaxObj.status==0

The problem is: &lt;b&gt;How do I differentiate Case 4 (access-control-allow-origin error) and Cases 2&amp;3?&lt;/b&gt;

In Case 4, the Chrome debug console shows the error:

`XMLHttpRequest cannot load http://192.168.8.247/. Origin http://localhost is not allowed by Access-Control-Allow-Origin.`

&lt;b&gt;How do I make that error known in Javascript?&lt;/b&gt;

I tried to find some indication in `ajaxObj` but nothing there seems to be different compared to Case 2&amp;3.

Here is a simple test I used:

	&lt;!DOCTYPE html PUBLIC &quot;-//W3C//DTD XHTML 1.0 Transitional//EN&quot; &quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&quot;&gt;

	//	doCORS(&quot;http://192.168.8.247&quot;);  // Case 4
	}

	function doCORS(url)
	{
		document.getElementById(&quot;statusDiv&quot;).innerHTML+=&quot;Processing url=&quot;+url+&quot;&lt;br&gt;&quot;;
		var ajaxObj=new XMLHttpRequest();
		ajaxObj.overrideMimeType(&#39;text/xml&#39;);
		ajaxObj.onreadystatechange = function()
		{
			var stat=document.getElementById(&quot;statusDiv&quot;);
			stat.innerHTML+=&quot;readyState=&quot;+ajaxObj.readyState;
			if(ajaxObj.readyState==4)
				stat.innerHTML+=&quot;, status=&quot;+ajaxObj.status;
			stat.innerHTML+=&quot;&lt;br&gt;&quot;;
		}
		ajaxObj.open(&quot;GET&quot;, url, true); 
		ajaxObj.send(null);
	}
	&lt;/script&gt;
	&lt;/head&gt;
	&lt;body onload=&quot;PgBoot()&quot;&gt;
	&lt;div id=&quot;statusDiv&quot;&gt;&lt;/div&gt;
	&lt;/body&gt;
	&lt;/html&gt;

Results using Chrome:

	Processing url=http://192.168.8.35
	readyState=1
	readyState=2
	readyState=3
	readyState=4, status=200
