a `&lt;div&gt;` can be focused if it has a `tabindex` attribute. *(the value can be set to -1)*

For example:

    $(&quot;#focus_point&quot;).attr(&quot;tabindex&quot;,-1).focus();
    
-------

**In addition**, consider setting `outline: none !important;` so it displayed without a focus rectangle.

    var element = $(&quot;#focus_point&quot;);
    element.css(&#39;outline&#39;, &#39;none !important&#39;)
           .attr(&quot;tabindex&quot;, -1)
           .focus();

you can use the below code to bring focus to a div, in this example the page scrolls to the `&lt;div id=&quot;navigation&quot;&gt;`

    $(&#39;html, body&#39;).animate({ scrollTop: $(&#39;#navigation&#39;).offset().top }, &#39;slow&#39;);

Focus doesn&#39;t work on divs by default.  But, according to this, you can make it work:

&gt; The focus event is sent to an element
&gt; when it gains focus. This event is
&gt; implicitly applicable to a limited set
&gt; of elements, such as form elements
&gt; (`&lt;input&gt;`, `&lt;select&gt;`, etc.) and links
&gt; (`&lt;a href&gt;`). In recent browser
&gt; versions, the event can be extended to
&gt; include all element types by
&gt; explicitly setting the element&#39;s
&gt; tabindex property. An element can gain
&gt; focus via keyboard commands, such as
&gt; the Tab key, or by mouse clicks on the
&gt; element.

I am using the `query` functions in order to build the SQL queries for my tables. Is there a way to see the actual query that is run? For instance log it somewhere?

So far the best I could do was to have a look at the cursor&#39;s member mQuery using a breakpoint. I&#39;d love to output the queries automatically though. This member is of course not public and does not have a getter.

Just for the record, here is an implementation of the accepted answer.

    	}
    
    	public SQLiteCursorFactory(boolean debugQueries) {

    		if (debugQueries) {
    			Log.d(&quot;SQL&quot;, query.toString());
    		}
    		return new SQLiteCursor(db, masterQuery, editTable, query);
    	}
    }

The answer will be very obvious I think, but I don&#39;t see it at the moment. 

**How can I convert a record array back to a regular ndarray?**

Suppose I have following simple structured array:

    x = np.array([(1.0, 4.0,), (2.0, -1.0)], dtype=[(&#39;f0&#39;, &#39;&lt;f8&#39;), (&#39;f1&#39;, &#39;&lt;f8&#39;)])

then I want to convert it to:

    array([[ 1.,  4.],
           [ 2., -1.]])

I tried ``asarray`` and ``astype``, but that didn&#39;t work.

**UPDATE (solved: float32 (f4) instead of float64 (f8))**

OK, I tried the solution of Robert (``x.view(np.float64).reshape(x.shape + (-1,))
``), and with a simple array it works perfectly. But with the array I wanted to convert it gives a strange outcome:

    data = np.array([ (0.014793682843446732, 0.006681123282760382, 0.0, 0.0, 0.0, 0.0008984912419691682, 0.0, 0.013475529849529266, 0.0, 0.0),

and then:

    data_array = data.view(np.float).reshape(data.shape + (-1,))

gives:

    In [8]: data_array
    Out[8]: 
    array([[  2.28080997e-20,   0.00000000e+00,   2.78023241e-27,

which is an array with other numbers and another shape. What did I do wrong?

How to use setInterval and clearInterval?

I&#39;ve started to write few jQuery plugins and figured it&#39;d be nice to setup my IDE with a jQuery plugin template. 

I have been reading some articles and posts on this site related to plugin convention, design, etc.. and thought I&#39;d try and consolidate all of that.

Below is my template, I am looking to use it frequently so was keen to ensure it generally conforms to jQuery plugin design convention and whether the idea of having multiple internal methods (or even its general design) would impact performance and be prone to memory issues.


    (function($)
    {
    	var PLUGIN_NAME = &quot;myPlugin&quot;; // TODO: Plugin name goes here.
    	var DEFAULT_OPTIONS =
    	{
    		// TODO: Default options for plugin.
    	};
    	var pluginInstanceIdCount = 0;
    
    	var I = function(/*HTMLElement*/ element)
    	{
    		return new Internal(element);
    	};
    
    	var Internal = function(/*HTMLElement*/ element)
    	{
    		this.$elem = $(element);
    		this.elem = element;
    		this.data = this.getData();
    		
    		// Shorthand accessors to data entries:
    		this.id = this.data.id;
    		this.options = this.data.options;
    	};
    
    	/**
    	 * Initialises the plugin.
    	 */
    	Internal.prototype.init = function(/*Object*/ customOptions)
    	{
    		var data = this.getData();
    
    		if (!data.initialised)
    		{
    			data.initialised = true;
    			data.options = $.extend(DEFAULT_OPTIONS, customOptions);
    
    			// TODO: Set default data plugin variables.
    			// TODO: Call custom internal methods to intialise your plugin.
    		}
    	};
    
    	/**
    	 * Returns the data for relevant for this plugin
    	 * while also setting the ID for this plugin instance
    	 * if this is a new instance.
    	 */
    	Internal.prototype.getData = function()
    	{
    		if (!this.$elem.data(PLUGIN_NAME))
    		{
    			this.$elem.data(PLUGIN_NAME, {
    				id : pluginInstanceIdCount++,
    				initialised : false
    			});
    		}
    
    		return this.$elem.data(PLUGIN_NAME);
    	};
    
    	// TODO: Add additional internal methods here, e.g. Internal.prototype.&lt;myPrivMethod&gt; = function(){...}
    
    	/**
    	 * Returns the event namespace for this widget.
    	 * The returned namespace is unique for this widget
    	 * since it could bind listeners to other elements
    	 * on the page or the window.
    	 */
    	Internal.prototype.getEventNs = function(/*boolean*/ includeDot)
    	{
    	 	return (includeDot !== false ? &quot;.&quot; : &quot;&quot;) + PLUGIN_NAME + &quot;_&quot; + this.id;
    	};
    
    	/**
    	 * Removes all event listeners, data and
    	 * HTML elements automatically created.
    	 */
    	Internal.prototype.destroy = function()
    	{
    		this.$elem.unbind(this.getEventNs());
    		this.$elem.removeData(PLUGIN_NAME);
    
    		// TODO: Unbind listeners attached to other elements of the page and window.

jQuery plugin template - best practice, convention, performance and memory impact

I&#39;m a novice web programmer so please forgive me if some of my &quot;jargon&quot; is not correct.
I&#39;ve got a project using ASP.NET using the MVC3 framework.  

I am working on an admin view where the admin will modify a list of equipment.  One of the functions is an &quot;update&quot; button that I want to use jquery to dynamically edit the entry on the webpage after sending a post to the MVC controller.

I presume this approach is &quot;safe&quot; in a single admin setting where there is minimal concern of the webpage getting out of sync with the database.

I&#39;ve created a view that is strongly typed and was hoping to pass the model data to the MVC control using an AJAX post.

In the following post, I found something that is similar to what I am looking at doing:
https://stackoverflow.com/questions/5698888/jquery-ajax-and-asp-net-mvc3-causing-null-parameters

I will use the code sample from the above post.

Model:

    public class AddressInfo 
    {
        public string Address1 { get; set; }
        public string Address2 { get; set; }
        public string City { get; set; }
        public string State { get; set; }
        public string ZipCode { get; set; }
        public string Country { get; set; }
    }

Controller:

    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Check(AddressInfo addressInfo)
        {
            return Json(new { success = true });
        }
    }

script in View:

    &lt;script type=&quot;text/javascript&quot;&gt;
    var ai = {
        Address1: &quot;423 Judy Road&quot;,
        Address2: &quot;1001&quot;,
        City: &quot;New York&quot;,
        State: &quot;NY&quot;,
        ZipCode: &quot;10301&quot;,
        Country: &quot;USA&quot;
    };

    $.ajax({
        url: &#39;/home/check&#39;,
        type: &#39;POST&#39;,
        data: JSON.stringify(ai),
        contentType: &#39;application/json; charset=utf-8&#39;,
        success: function (data.success) {
            alert(data);
        },
        error: function () {
            alert(&quot;error&quot;);
        }
    });
    &lt;/script&gt;

I have not had a chance to use the above yet.  But I was wondering if this was the &quot;best&quot; method to pass the model data back to the MVC control using AJAX?

Should I be concerned about exposing the model information?
