5,049,746 | 5,049,747 | jQuery UI drag and drop input field contents | <p>I working on an application where aircraft loadmasters enter weights into a number of individual pallet positions. It's often necessary to change where a given pallet has been put, so I'm trying to fix it so that they can drag and drop a pallet from one position to another.</p>
<p>Rather than deal with the input fields directly, I've chosen for the moment (perhaps wrongly) to have alongside each input field open and close brackets "[ ]" to use as a handle. Each handle element has class='drag1'. Given the code below:</p>
<pre><code>alert($('.drag1').length);
$('.drag1').draggable({helper:'clone'});
$('.drag1').droppable({
drop: alert('here')
});
</code></pre>
<p>When the page loads, the first alert properly reports the correct number of pallet positions (74) and then I immediately get the second alert 'here' once and only once.</p>
<p>What I was hoping for was that I would get the second alert only when I dropped rather than before I did anything.</p>
<p>The dragging is working in that a clone of the "[ ]" moves around, but nothing happens when I drop it on another "[ ]".</p>
<p>The question is: Why does the drop fire when the page is loaded rather when when the drag is dropped?</p>
<p>Perhaps I can't have an element be both draggable and droppable?</p>
<p>The page is at <a href="http://terryliittschwager.com/WB/load.html?N100YY" rel="nofollow">http://terryliittschwager.com/WB/load.html?N100YY</a></p>

1,206,765 | 1,206,766 | Check if checkbox is NOT checked on click - jQuery | <p>I want to check if a checkbox just got unchecked, when a user clicks on it. The reason for this is because i want to do a validation when a user unchecks a checkbox. Because atleast one checkbox needs to be checked. So if he unchecks the last one, then it automatically checks itself again.</p>
<p>With jQuery i can easily find out wether it's checked or not:</p>
<pre><code>$('#check1').click(function() {
if($(this).is(':checked'))
alert('checked');
else
alert('unchecked');
});
</code></pre>
<p>But i actually only want to have an if statement that checks if a checkbox just got unchecked.</p>
<p>So i thought i could do that with the following code:</p>
<pre><code>$('#check2').click(function() {
if($(this).not(':checked'))
alert('unchecked');
else
alert('checked');
});
</code></pre>
<p>But this will always show the 'unchecked' message. Not really what i was expecting...</p>
<p><strong>demo:</strong> <a href="http://jsfiddle.net/tVM5H/" rel="nofollow">http://jsfiddle.net/tVM5H/</a></p>
<p>So eventually i need something like:</p>
<pre><code>$('#check2').click(function() {
if($(this).not(':checked')) {
// Got unchecked, so something!!!
}
});
</code></pre>
<p>But obviously this doesn't work. I rather don't want to use the first example, because then i'd have an unnecessary 'else' statement when i only need one 'if' statement.</p>
<p>So first thing, is this a jQuery bug? Cause to me it's unexpected behaviour. And second, anyone any ides for a good alternative?</p>

5,073,255 | 5,073,256 | Why is assigning a PHP variable printing a value out on the screen? | <p>This has me completely baffled, I'm doing the following:</p>
<pre><code>if($tasks = someFunction(1))
{
}
</code></pre>
<p>someFunction() returns an array of records from a database. For some reason, assigning this array to $tasks causes a number to be printed out to the screen. The number it prints is the number of records that it has returned, but at no point do I ever echo this variable.</p>
<p>To confirm, I added the following code:</p>
<pre><code>$tasks = someFunction(1);
$tasks = someFunction(1);
$tasks = someFunction(1);
</code></pre>
<p>Above the if statement, and sure enough I was greeted by "4444" on my screen (It was returning 4 records). I've implemented code that's basically identical elsewhere in my code and have never run into this, I'm confused as to how a variable assignment can cause a value to display on the screen.</p>

3,196,113 | 3,196,114 | Android: MediaStore.Images.Media.EXTERNAL_CONTENT_URI ... show pictures in full size? | <p>I guess this question has been asked before, but I can't seem to find a proper answer/solution.</p>
<p>Have a note-taking app, which allows to take pictures. For that I start an intent, that starts up the built-in camera-app. So far so good.</p>
<p>But when I show that image in my app, it's in a much smaller format :(</p>
<p>The funny/weird thing is, that the camera-app did take a full-resolution picture! But for some reason I can't get the full version to show in my app???</p>
<p>So, when I use the standard Android Gallery app, and go to that picture, it is very obvious that it's full size (I can zoom in and see details I really can't see when I zoom in, in my own app). Also, the dimensions are really those of the original picture, taken with the 5MP camera.</p>
<p>In my app, they are very small. My phone has Android 2.2, but the same happens on my emulator (Android 2.1).</p>
<p>How should I retrieve the pictures in my app??? Tried a couple of ways, but none works :( Don't need a complete example (allthough that's very welcome), just a few clues are enough to search for myself.</p>
<p>Tx in advance!!</p>

3,763,677 | 3,763,678 | Custom Content Provider - openInputStream(), openOutputStream() | <p>The content provider / resolver APIs provide a complicated, but robust way of transferring data between processes using an URI and the openInputStream() and openOutputStream() methods. Custom content providers have the ability to override the openFile() method with custom code to effectively resolve an URI into a Stream; however, the method signature of openFile() has an ParcelFileDescriptor return type and it is not clear how one might generate a proper representation for dynamically generated content to return from this method.</p>

When i change the member from 'array' to something else it works, so it seems that the compiler thinks that the member name 'array' is actually the constructor of the struct array. It's obviously not a good practice to name the member like the struct but it's already written that way. Can i tell the MSVS compiler to ignore this problem or i should rename all members that are the same as the struct name.</p>

<blockquote>
<p>Name: %name%<br>
Status: %status%<br>
Address: %address%<br>
Telephone: %telephone%</p>

<p>What's the best way of working?</p>
<p>Why is lint not working?</p>
<p>Thanks!</p>

3,638,589 | 3,638,590 | Jquery Hover image and Alt text - execution order? | <p>I've a very simple jQuery script to change an image and display the alt text when a thumbnail is hovered over.</p>
<p>Both image and Alt text display in the same div. The code works but the text displays before the image changes and so briefly resizes the div for long alt text:</p>
<pre><code>$("#thumbwrapper li img").hover(function(){
$('#main_img').attr('src',$(this).attr('src').replace('thumb/', ''));
$("#desc").html( $(this).attr("alt") );
});
</code></pre>
<p>I need to order these two so the IMAGE changes 1st and then the alt text. I'm guessing I need to nest a second function but don't know how.
This is my guess of nesting function() but it just breaks the alt text changing:</p>
<pre><code>$("#thumbwrapper li img").hover(function(){
$('#main_img').attr('src',$(this).attr('src').replace('thumb/', ''),function(){
$("#desc").html( $(this).attr("alt") );
});
});

While they contain dynamic content, I still would like some of the interactivity of javascript. All of my attempts have been futile, however, as nothing works.

<p>The following code is some basic things I've written based on some HTML DOM tutorials I've read. The problem is it doesn't work at all. So can anyone tell me what is going on here, about why it doesn't work at all. And yes, I do have javascript turned on in my browser.</p>

In this callback, I need to take a special action if it's the n'th & final callback. I can't work out how to determine if a callback is the final one, I thought about setting a counter and decrementing it each time, but due to the nested loop I don't know in advance how many async calls will be made (without working it out in advance which would be inefficient). Any ideas on an elegant approach to this?</p>

3,351,393 | 3,351,394 | ListView -Dynamic Controls and DataPager events | <p>I have a listView control which is bound to an object datasource. In the ListView1_ItemDataBound event, I am generating some dynamic controls. I do this because depending on a particular column value, i might need to generate textbox, radio button, check box etc. </p>
<p>Some code here:</p>
<pre><code> ListViewDataItem item = (ListViewDataItem)e.Item;
typez = Convert.ToInt32(DataBinder.Eval(item.DataItem,"Type").ToString());
if (typez == 1) //1 means generate radibutton
{
string[] options = DataBinder.Eval(item.DataItem, "QuestionDetail").ToString().Split(new string[] { delimiter }, StringSplitOptions.None);
questionID = Convert.ToInt32(DataBinder.Eval(item.DataItem, "Question_ID").ToString());
int optionCount = 1;
RadioButtonList rbl = new RadioButtonList();
//set ID for the radiobtnList to the questionid no.
rbl.ID = "mcq_" + questionID;
foreach (string s in options)
{
//adds the MCQ options to list item
ListItem li = new ListItem(Util.GetAlphabet(optionCount).ToUpper() + ". " + s, Util.GetAlphabet(optionCount).ToUpper(), true);
rbl.Items.Add(li);
optionCount++;
}
//PlaceHolder PlaceHolder1 = (PlaceHolder)e.Item.FindControl("PlaceHolder1");
PlaceHolder1.Controls.Add(rbl);

<p>I need to get the radio button selected value so that I can save it or put in some session variable so that when user comes back to this page he can see his previuos values.</p>
<p>Could someone please suggest some insight on what I am doing wrong.</p>
