The default is `0` ([technically it&#39;s undefined][1], but behaves as 0).  This means no timeout in jQuery itself...if the browser has some timeout it&#39;s entirely possible you&#39;ll hit that.

Only when a `timeout` option is specified [does jQuery even call `setTimeout()`][2].

In git, I&#39;ve been making commits onto the master branch, when really I should have been working on a feature branch. I want to change this so that master is back to where it started, and what was on master is now on a new branch. Basically, my commit history looks like this:

    A -- B -- C -- D -- E
              |         |
              |       master
         origin/master

And I want it to look like this:

            master
              |
    A -- B -- C -- D -- E
              |         |
              |       new_branch
         origin/master

How can I change where master points?

A few users have been asking me Android lock screen widgets for my app - I believe they want a widget that stays on their lock screens and allows them to interact with the app.

I haven&#39;t been able to find any official documentation for this - the only thing I found was apps that will take home screen widgets and put them on the lock screen for you.

Any clues on where I learn more about building true lock-screen widgets?

Does anyone know what the default jQuery ajax timeout value is?

Let&#39;s assume I have a jQuery object of a DIV element in body. I&#39;d like to obtain document object by traversing. Can it be possible ?

Note: window.document is not a option in my case.

Thank you.

Get document object from a child element

So according to the [jQuery Ajax docs][1], it serializes data in the form of a query string when sending requests, but setting `processData:false` should allow me to send actual JSON in the body.  Unfortunately I&#39;m having a hard time determining first, if this is happening and 2nd what the object looks like that is being sent to the server.  All I know is that the server is not parsing what I&#39;m sending.

When using [http client][2] to post an object literal `{someKey:&#39;someData&#39;}`, it works. But when using jQuery with `data: {someKey:&#39;someData&#39;}`, it fails.  Unfortunately when I analyze the request in Safari, it says the message payload is `[object Object]` ... great...  and in Firefox the post is blank...

When logging the body content on the Java side it literally gets `[object Object]` so how does one send REAL JSON data??

Has anyone had experience with a Java service serializing JSON data in the request body, with the request sent from jQuery?  

BTW here is the full $.ajax request:

    $.ajax({
    	contentType: &#39;application/json&#39;,
    	data: {
    		&quot;command&quot;: &quot;on&quot;
    	},
    	dataType: &#39;json&#39;,
    	success: function(data){
    		app.log(&quot;device control succeeded&quot;);
    	},
    	error: function(){
    		app.log(&quot;Device control failed&quot;);
    	},
    	processData: false,
    	type: &#39;POST&#39;,
    	url: &#39;/devices/{device_id}/control&#39;
    });

jQuery posting valid json in request body

Im trying to get a list of line items to a webpage using JSON, which will then be manipulated and sent back to the server by ajax request using the same JSON structure that arrived (except having had a field values changed). 

Receiving data from the server is easy, manipulation even easier! but sending that JSON data back to the server for saving... suicide time! PLEASE can someone help!

**Javascript**

    var lineitems;

    // get data from server
    $.ajax({
        url: &#39;/Controller/GetData/&#39;,
        success: function(data){
            lineitems = data;
        }
    });
    
    // post data to server
    $.ajax({
        url: &#39;/Controller/SaveData/&#39;,
        data: { incoming: lineitems }
    });

**C# - Objects**

    public class LineItem{
        public string reference;
        public int quantity;
        public decimal amount;
    }

**C# - Controller**

    public JsonResult GetData()
    {
        IEnumerable&lt;LineItem&gt; lineItems = ... ; // a whole bunch of line items
        return Json(lineItems);
    }
    
    public JsonResult SaveData(IEnumerable&lt;LineItem&gt; incoming){
        foreach(LineItem item in incoming){
            // save some stuff
        }
        return Json(new { success = true, message = &quot;Some message&quot; });
    }

The data arrives at the server as serialized post data. The automated model binder tries to bind `IEnumerable&lt;LineItem&gt; incoming` and surprisingly gets the resulting `IEnumerable` has the correct number of `LineItems` - it just doesnt populate them with data.

**SOLUTION**

Using answers from a number of sources, primarily `djch` on another stackoverflow post and `BeRecursive` below, I solved my problem using two main methods.

*Server Side* 

The deserialiser below requires reference to `System.Runtime.Serialization` and `using System.Runtime.Serialization.Json`

	private T Deserialise&lt;T&gt;(string json)
	{
	    using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
	    {
	        var serialiser = new DataContractJsonSerializer(typeof(T));
	        return (T)serialiser.ReadObject(ms);
	    }
	}
	
	public void Action(int id, string items){
	    IEnumerable&lt;LineItem&gt; lineitems = Deserialise&lt;IEnumerable&lt;LineItem&gt;&gt;(items);
	    // do whatever needs to be done - create, update, delete etc.
	}

*Client Side*

It uses json.org&#39;s stringify method, available in this dependecy https://github.com/douglascrockford/JSON-js/blob/master/json2.js (which is 2.5kb when minified)

    $.ajax({
        type: &#39;POST&#39;,
        url: &#39;/Controller/Action&#39;,
        data: { &#39;items&#39;: JSON.stringify(lineItems), &#39;id&#39;: documentId }
    });

I have the following:

	$(document).ready(function()
	{
		$(&quot;#select-all-teammembers&quot;).click(function() {
			$(&quot;input[name=recipients\\[\\]]&quot;).attr(&#39;checked&#39;, true);
		});					
	});

I&#39;d like the `id=&quot;select-all-teammembers&quot;` when clicked to toggle between checked and unchecked. Ideas? that aren&#39;t dozens of lines of code?

I&#39;m getting this error from time to time and don&#39;t know what causing this:  
When trying to run/debug an Android app on a real device (Galaxy Samsung S in my case) I&#39;m getting the following error in the Console:  

&gt; Failed to install *.apk on device *: 

&gt; timeout   Launch canceled!

This is all the Console is telling me. LogCat doesn&#39;t provide any information. Eclipse Problems view is not showing any issues. 


I tried the following steps with no success:  
1. Cleaning the project (Project-&gt;Clean)  
2. Restarting device, Eclipse, laptop, all of the above...  
3. Moving the project to a location without spaces, according to &lt;https://stackoverflow.com/questions/4552435/failed-to-install-apk-on-device-emulator-5554-timeout&gt;   


The app has been debugged in the past on that device many times (app is live on Market), but this problem happens every so often, and is VERY FRUSTRATING...

Any help would be greatly appreciated! Thanks.

Android error: Failed to install *.apk on device *: timeout

I&#39;m new to .Net 4.0&#39;s Tasks and I wasn&#39;t able to find what I thought would be a Task based replacement or implementation of a Timer, e.g. a periodic Task. Is there such a thing?

***Update***
I came up with what I think is a solution to my needs which is to wrap the &quot;Timer&quot; functionality inside a Task with child Tasks all taking advantage of the CancellationToken and returns the Task to be able to participate in further Task steps.  

    public static Task StartPeriodicTask(Action action, int intervalInMilliseconds, int delayInMilliseconds, CancellationToken cancelToken)
    { 
        Action wrapperAction = () =&gt;
        {
            if (cancelToken.IsCancellationRequested) { return; }
    
            action();
        };
    
        Action mainAction = () =&gt;
        {
            TaskCreationOptions attachedToParent = TaskCreationOptions.AttachedToParent;
    
            if (cancelToken.IsCancellationRequested) { return; }
    
            if (delayInMilliseconds &gt; 0)
                Thread.Sleep(delayInMilliseconds);
    
            while (true)
            {
                if (cancelToken.IsCancellationRequested) { break; }
    
                Task.Factory.StartNew(wrapperAction, cancelToken, attachedToParent, TaskScheduler.Current);
    
                if (cancelToken.IsCancellationRequested || intervalInMilliseconds == Timeout.Infinite) { break; }
    
                Thread.Sleep(intervalInMilliseconds);
            }
        };
    
        return Task.Factory.StartNew(mainAction, cancelToken);
    }
