From the source code:

    if ( status &gt;= 200 &amp;&amp; status &lt; 300 || status === 304 ) {

So any 2xx and under special circumstances 304 as well. 304 has some extra handling though, check the source for more info.

You&#39;ll find this in the done callback.  A success is any status greater than or equal to 200 and less than 300.    A notmodified (304) is also viewed as a success.

I want to update a table in a statement that has several joins.  While I know the order of joins doesn&#39;t really matter (unless you you are using optimizer hints) I ordered them a certain way to be most intuitive to read.  However, this results in the table I want to update not being the one I start with, and I am having trouble updating it.  

A dummy example of what I&#39;d like to do is something like:

    UPDATE b
    FROM tableA a
    JOIN tableB b
       ON a.a_id = b.a_id
    JOIN tableC c
       ON b.b_id = c.b_id
    SET b.val = a.val+c.val
    WHERE a.val &gt; 10
        AND c.val &gt; 10;

There are many posts about updating with joins here however they always have table being updated first.  I know this is possible in SQL Server and hopefully its possible in MySQL Too!

My Git repository got corrupted after a couple of hard reboots due to power supply issues and now I&#39;m unable to fix it (I was in the middle of staging some files at the last power failure):

    $ git status
    fatal: failed to read object 3d18855708b0f127d40c13c679559d7679228b69: Invalid argument
    $ git fsck
    fatal: failed to read object 24377c609184c192f3f3c1733bac7115c1080758: Invalid argument
    $ git branch -a
    (...works, lists branches...)
    $ git checkout someotherbranch
    fatal: failed to read object 3d18855708b0f127d40c13c679559d7679228b69: Invalid argument
    $ git log

    $ git log someotherbranch
    (...works, shows commits...)

So, as you can see, my current branch is pretty screwed up, and I don&#39;t seem to be able to fix it. What can I try to repair this?

The [documentation][1] doesn&#39;t seem to specify exactly what is meant by &#39;success&#39; in jQuery.ajax.  Is it any 2xx code?  Only 200?

All,
I&#39;m using the jQuery UI for the date picker. I&#39;m trying to check with javascript though that the date the user has entered is in the past. Here is my form code:

    &lt;input type=&quot;text&quot; id=&quot;datepicker&quot; name=&quot;event_date&quot; class=&quot;datepicker&quot;&gt;

Then how would I check this with Javascript to make sure it isn&#39;t a date in the past? Thanks

Check if date is in the past Javascript

I had thought these two were the same, but they appear to not be. I&#39;ve generally been using `$obj.attr(&quot;value&quot;)` to work with form fields, but on the page I&#39;m currently building, `$obj.attr(&quot;value&quot;)` does not return the text I enter in my field. However, `$obj.val()` does. 

On a different page I&#39;ve built, both `$obj.attr(&quot;value&quot;)` and `$obj.val()` return the text entered in the form field. 

What could account for `$obj.attr(&quot;value&quot;)` working as expected in one case but not in another?

What is the proper way to set and retrieve a form field&#39;s value using jQuery?

jQuery .val() vs .attr(&quot;value&quot;)

RequireJS seems to do something internally that caches required javascript files. If I make a change to one of the required files, I have to rename the file in order for the changes to be applied.  

The common trick of appending a version number as a querystring param to the end of the filename does not work with requirejs `&lt;script src=&quot;jsfile.js?v2&quot;&gt;&lt;/script&gt;` 

What I am looking for is a way to prevent this internal cacheing of RequireJS required scripts without having to rename my script files every time they are updated.

**Cross-Platform Solution:**

I am now using `urlArgs: &quot;bust=&quot; + (new Date()).getTime()` for automatic cache-busting during development and `urlArgs: &quot;bust=v2&quot;` for production where I increment the hard-coded version num after rolling out an updated required script.

**Note:**

@Dustin Getz mentioned in a recent answer that Chrome Developer Tools will drop breakpoints during debugging when Javascript files are continuously refreshed like this. One workaround  is to write `debugger;` in code to trigger a breakpoint in most Javascript debuggers.

**Server-Specific Solutions:**

For specific solutions that may work better for your server environment such as Node or Apache, see some of the answers below.

Prevent RequireJS from Caching Required Scripts

What is meant by easing function in the context of animation. It seems that dojo, jquery, silverlight, flex and other UI systems have the notion of easing function. I could not locate a good explanation of easing functions? Can anyone explain the concept of easing functions, or point a good explanation of them, I am interested in the concept not in the specific details of a framework? 

Is easing strictly used for location or is it general and can be applied to any property of an object?

Take a look at this simple HTML:

```html
&lt;div id=&quot;wrap1&quot;&gt;
  &lt;iframe id=&quot;iframe1&quot;&gt;&lt;/iframe&gt;
&lt;/div&gt;
&lt;div id=&quot;warp2&quot;&gt;
  &lt;iframe id=&quot;iframe2&quot;&gt;&lt;/iframe&gt;
&lt;/div&gt;
```

Let&#39;s say I wanted to move the wraps so that the `#wrap2` would be before the `#wrap1`. The iframes are polluted by JavaScript. I am aware of jQuery&#39;s `.insertAfter()` and `.insertBefore()`. However, when I use those, the iFrame loses all of its HTML, and JavaScript variables and events.

Lets say the following was the iFrame&#39;s HTML:

```html
&lt;html&gt;
  &lt;head&gt;
    &lt;script type=&quot;text/javascript&quot; src=&quot;jquery.js&quot;&gt;&lt;/script&gt;
    &lt;script type=&quot;text/javascript&quot;&gt;
      // The variable below would change on click
      // This represents changes on variables after the code is loaded
      // These changes should remain after the iFrame is moved
      variableThatChanges = false;
      $(function(){
        $(&quot;body&quot;).click(function(){ 
          variableThatChanges = true; 
        });
      });
    &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;div id=&#39;anything&#39;&gt;Illustrative Example&lt;/div&gt;
  &lt;/body&gt;
&lt;/html&gt;
```

In the above code, the variable `variableThatChanges` would...change if the user clicked on the body. This variable, and the click event, should remain after the iFrame is moved (along with any other variables/events that have been started)

My question is the following: **with JavaScript (with or without jQuery), how can I move the wrap nodes in the DOM (and their iframe childs) so that the iFrame&#39;s window stays the same, and the iFrame&#39;s events/variables/etc stay the same?**

I&#39;m just getting started with Node, APIs, and web applications.

I understand the basic workings of Node.js and Express, but now I want to start making calls to other service&#39;s APIs and to do stuff with their data.

Can you outline basic HTTP requests and how to grab/parse the responses in Node? I&#39;m also interested in adding specific headers to my request (initially I&#39;m using the http://www.getharvest.com API to crunch my time sheet data).

P.S. This seems simple, but a lot of searching didn&#39;t turn up anything that answered my question. If this is dupe, let me know and I&#39;ll delete.

Thanks!

Simple API Calls with Node.js and Express

I created a function in javascript like that:
```JavaScript
function addNewManufacturer() {
    var name = $(&quot;#id-manuf-name&quot;).val();
    var address = $(&quot;#id-manuf-address&quot;).val();
    var phone = $(&quot;#id-manuf-phone&quot;).val();
    
    var sendInfo = {
        Name: name,
        Address: address,
        Phone: phone
    };
    
    $.ajax({
        type: &quot;POST&quot;,
        url: &quot;/Home/Add&quot;,
        dataType: &quot;json&quot;,
        success: function (msg) {
            if (msg) {
                alert(&quot;Somebody&quot; + name + &quot; was added in list !&quot;);
                location.reload(true);
            } else {
                alert(&quot;Cannot add to list !&quot;);
            }
        },
        data: sendInfo
    });
}
```
I called `jquery.json-2.3.min.js` script file and I used it for `toJSON(array)` method.

In controller, I have this `Add` action

    [HttpPost]
    public ActionResult Add(PersonSheets sendInfo) {
        bool success = _addSomethingInList.AddNewSomething( sendInfo );

        return this.Json( new {
             msg = success
        });
          
    }

**But `sendInfo` as method parameter becomes null.**

The model:

    public struct PersonSheets
    {
        public int Id;
        public string Name;
        public string Address;
        public string Phone;
    }
    
    public class PersonModel
    {
        private List&lt;PersonSheets&gt; _list;
        public PersonModel() {
             _list= GetFakeData();
        }
    
        public bool AddNewSomething(PersonSheets info) {
             if ( (info as object) == null ) {
                throw new ArgumentException( &quot;Person list cannot be empty&quot;, &quot;info&quot; );
             }
    
             PersonSheets item= new PersonSheets();
             item.Id = GetMaximumIdValueFromList( _list) + 1;
             item.Name = info.Name;
             item.Address = info.Address;
             item.Phone = info.Phone;
                 
             _list.Add(item);
    
             return true;
        }
    }

How could I do in action method when the data was sent with POST ?

I don&#39;t know how to use. 
Also, it is possible to send back the response (to ajax) via JSON ?

I have recently been learning Python and am dipping my hand into building a web-scraper.  It&#39;s nothing fancy at all; its only purpose is to get the data off of a betting website and have this data put into Excel.

Most of the issues are solvable and I&#39;m having a good little mess around. However I&#39;m hitting a massive hurdle over one issue. If a site loads a table of horses and lists current betting prices this information is not in any source file. The clue is that this data is live sometimes, with the numbers being updated obviously from some remote server. The HTML on my PC simply has a hole where their servers are pushing through all the interesting data that I need.

Now my experience with dynamic web content is low, so this thing is something I&#39;m having trouble getting my head around. 

I think Java or Javascript is a key, this pops up often. 

The scraper is simply a odds comparison engine.  Some sites have APIs but I need this for those that don&#39;t. I&#39;m using the scrapy library with Python 2.7

I do apologize if this question is too open-ended. In short, my question is: how can scrapy be used to scrape this dynamic data so that I can use it?  So that I can scrape this betting odds data in real-time?

Can scrapy be used to scrape dynamic content from websites that are using AJAX?

What is difference between HTTP and HTTPS header? 

 1. What are benefits of using HTTPS over HTTP? 
 2. What settings  needs to be done for making website HTTPS?
 3. Can we use HTTPS for only login purpose and then onwords HTTP?

I need to authenticate a client when he sends a request to an API. The client has an API-token and I was thinking about using the standard `Authorization` header for sending the token to the server.

Normally this header is used for `Basic` and `Digest` authentication. But I don&#39;t know if I&#39;m allowed to customize the value of this header and use a custom authentication scheme, e.g:

    Authorization: Token 1af538baa9045a84c0e889f672baf83ff24

Would you recommend this or not? Or is there a better approach for sending the token?

Customize the Authorization HTTP header

I have an application that sends messages to users. In a post request a XML string is transferred that consists of all the users that should receive that particular message. If any of the users in the list do not exist I give the list of missing users back to the client for further evaluation. 

Now I&#39;m asking myself what would be the proper status code for the application saying that the request was accepted but there were things that couldn&#39;t be done. 

The problem would be avoided if it weren&#39;t allowed to include missing users in the list. Then the sending attempt would just get an 4xx error. But there is no point in forming the API this way.
On the other hand I could consider the error condition to be purely application specific. But sending a 200 just does not feel right. And it would be nice to give the client a hint when to look deeply in the error response. e.g. to avoid sending messages to that users over and over

HTTP status code for a partial successful request

    Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
    Accept-Language: en-us,en;q=0.5
    Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7

What do these &#39;q=%f&#39; mean?

What is q=0.5 in Accept* HTTP headers?
