In IE, use the [`setActive()`][1] method of the element that you want to be the active element. In other browsers that support `activeElement`, you can use the `focus()` method of the element, so long as the element is capable of receiving the focus (form elements, editable elements, elements with `tabindex` set).

If you want to set the activeElement back to the default (the `&lt;body&gt;` element in most browsers), just call the active element&#39;s `blur()` method:

    document.activeElement.blur();

You can just [`.focus()`][1] the element you want and it&#39;ll be the new `document.activeElement`.

Is it possible to disable future date from today?

Let say today is 23/10/2010, so 24/10/2010 onwards are disabled.

Sorry I am very new in jQuery and JavaScript.

I have some questions about the usage of the close() method when using Java InputStreams.  From what I see and read from most developers, you should always explicitly call close() on an InputStream when it is no longer needed.  But, today I was looking into using a Java properties file, and every example I have found has something like this:

    Properties props = new Properties();
    try {
        props.load(new FileInputStream(&quot;message.properties&quot;));
        //omitted.
    } catch (Exception ex) {}

With the above example, there is no way to explicitly call close() because the InputStream is unreachable after it is used.  I have seen many similar uses of InputStreams even though it seems to contradict what most people say about explicitly closing.  I read through Oracle&#39;s JavaDocs and it does not mention if the Properties.load() method closes the InputStream.  I am wondering if this is generally acceptable or if it is preferred to do something more like the following:

    Properties props = new Properties();
    InputStream fis = new FileInputStream(&quot;message.properties&quot;);
    try {
        props.load(fis);
        //omitted.
    } catch (Exception ex) {
        //omitted.
    } finally {
        try {
            fis.close();
        } catch (IOException ioex) {
            //omitted.
        }
    }

Which way is better and/or more efficient?  Or does it really matter?

Is there a cross-browser solution to replace selected text in *contenteditable* div? &lt;br&gt;
I simply want users to highlight some text and replace the highlighted text with `xxxxx`.


replace selected text in contenteditable div

I have this HTML code:

    &lt;html&gt;
      &lt;head&gt;
        &lt;script type=&quot;text/javascript&quot;&gt;
          function GetDoc(x)
          {
            return x.document ||
              x.contentDocument ||
              x.contentWindow.document;
          }
    
          function DoStuff()
          {
            var fr = document.all[&quot;myframe&quot;];
            while(fr.ariaBusy) { }
            var doc = GetDoc(fr);
            if (doc == document)
              alert(&quot;Bad&quot;);
            else 
              alert(&quot;Good&quot;);
          }
        &lt;/script&gt;
      &lt;/head&gt;
      &lt;body&gt;
        &lt;iframe id=&quot;myframe&quot; src=&quot;http://example.com&quot; width=&quot;100%&quot; height=&quot;100%&quot; onload=&quot;DoStuff()&quot;&gt;&lt;/iframe&gt;
      &lt;/body&gt;
    &lt;/html&gt;

The problem is that I get message &quot;Bad&quot;. That mean that the document of iframe is not got correctly, and what is actualy returned by GetDoc function is the parent document.

I would be thankful, if you told where I do my mistake. (I want to get document hosted in IFrame.)

Thank you.



Get IFrame&#39;s document, from JavaScript in main document

I missed semicolons in some of the places in my JavaScript, but its not throwing error in any of the browsers. Is the `;` at the end needed?

Do we need semicolon at the end?

How can I achieve an elseif in a JavaScript condition?



&quot;elseif&quot; syntax in JavaScript

Admittedly, there are similar questions lying around on Stack Overflow, but it seems none quite meet my requirements.

Here is what I&#39;m looking to do:

* Upload an entire form of data, one piece of which is a **single** file
* Work with Codeigniter&#39;s file upload library

Up until here, all is well. The data gets in my database as I need it. But I&#39;d also like to submit my form via an AJAX post:

* Using the native HTML5 File API, not flash or an iframe solution
* Preferably interfacing with the low-level `.ajax()` jQuery method

I think I could imagine how to do this by auto-uploading the file when the field&#39;s value changes using pure javascript, but I&#39;d rather do it all in one fell swoop on for submit in jQuery. I&#39;m thinking it&#39;s not possible to do via query strings as I need to pass the entire file object, but I&#39;m a little lost on what to do at this point. 

Can this be achieved?

Using HTML5 file uploads with AJAX and jQuery

I have 3 text boxes for a phone number.  As the user types, it automatically moves from one textbox to the next.  When the user presses backspace, I can move focus to the previous text box.  The problem is that in IE, focus is set to the beginning of the text box.  Here&#39;s my code, which works fine in chrome.

    $(&#39;#AreaCode&#39;).live(&#39;keyup&#39;, function (event) {
        if ($(this).val().length == $(this).attr(&quot;maxlength&quot;))
            $(&#39;#Prefix&#39;).focus();
    });

    $(&#39;#Prefix&#39;).live(&#39;keyup&#39;, function (event) {
        if (event.keyCode == 8 &amp;&amp; $(this).val().length == 0)
            $(&#39;#AreaCode&#39;).focus();

        if ($(this).val().length == $(this).attr(&quot;maxlength&quot;))
            $(&#39;#Number&#39;).focus();
    });

    $(&#39;#Number&#39;).live(&#39;keyup&#39;, function (event) {
        if (event.keyCode == 8 &amp;&amp; $(this).val().length == 0)
            $(&#39;#Prefix&#39;).focus();
    });

How do I make the focus set at the end of the contents when going backwards?

Set Focus After Last Character in Text Box

I got a relative simple question. I have an activity with a lot of EditText&#39;s in them. When I open the activity it automatically focusses to the first EditText and displays the virtual keyboard.

How can I prevent this?

Automatic popping up keyboard on start Activity

My layout contains `ListView`, `SurfaceView` and `EditText`. When I click on the `EditText`, it receives focus and the on-screen keyboard pops up. When I click somewhere outside of the `EditText`, it still has the focus (it shouldn&#39;t).
I guess I could set up `OnTouchListener`&#39;s on the other views in layout and manually clear the `EditText`&#39;s focus. But seems too hackish...

I also have the same situation in the other layout - list view with different types of items, some of which have `EditText`&#39;s inside. They act just like I wrote above.

The task is to make `EditText` lose focus when user touches something outside of it.

I&#39;ve seen similar questions here, but haven&#39;t found any solution...

EditText, clear focus on touch outside

I would like to be able to remove the focus from the EditText. For example if the Keyboard appears, and the user hides it with the back button, I would like the focus and the cursor to disappear. How can it be done?



Android: Force EditText to remove focus?

I want to automatically show the soft-keyboard when an `EditText` is focused (if the device does not have a physical keyboard) and I have two problems:

 1. When my `Activity` is displayed, my `EditText` is focused but the keyboard is not displayed, I need to click again on it to show the keyboard (it should be displayed when my `Activity` is displayed).

 2. And when I click done on the keyboard, the keyboard is dissmissed but the `EditText` stays focused and y don&#39;t want (because my edit is done).

To resume, my problem is to have something more like on the iPhone: which keep the keyboard sync with my `EditText` state (focused / not focused) and of course does not present a soft-keyboard if there is a physical one.
