• send javaScript variable to php variable

  - by mrbunyrabit

  First i thought that i had to convert javascript to php, but then i found out that cant because of server and client side executions. So now I simply want to send ONE variable <script type="text/javascript"> function scriptvariable() { var theContents = "the variable"; } </script> to a php variable <?php $phpvariable ?> That function in the javascript executes when lets say i click on a button. Now i have Nooo idea how to get that phpvariable Equal to the javascript one so i can use that phpvariable to look up stuff in my Database. I know i can add it to my url or some thing, and just refresh the page.. But id like to do it with AJAX as further in my webpage i might have to use this Ajax method.. So is there an easy way to do this without having to dump pages of code on my page to do one simple thing?

• UIImageWriteToSavedPhotosAlbum working... sometimes.

  - by MegaEduX

  Hello, UIImageWriteToSavedPhotosAlbum is only working sometimes. Sometimes it works, sometimes it doesn't, exact same function. - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { NSLog(@"Saving image to camera roll..."); UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil); NSLog(@"Done!"); } I am using a UIImagePicker controller to get the image that then calls that function. Sometimes it saves it to the camera roll, other times it simply doesn't. Anyone has any idea? Thanks in advance.

• How to stop and remove anythingSlider

  - by d_rail

  I have several sliders on the same page and but don't show all at once. I would like to be able to stop a slider and remove the animation by an event function. As it works right now, if I hide a slider, it still runs in the background, the dom shows the images rotating and the url parameters change. I've seen this question, but it did not work for me: How to stop AnythingSlider when Flowplayer clicked This is also somewhat similar, but I want to remove the slider instead of restarting: AnythingSlider: how to restart slideshow function stopAnythingSlider() { // I receive `TypeError: $(".anythingSlider").data("AnythingSlider") is undefined` // $('.anythingSlider').data('AnythingSlider').startStop(false); }

• In Python, is there a way to call a method on every item of an iterable? [closed]

  - by Thane Brimhall

  Possible Duplicate: Is there a map without result in python? I often come to a situation in my programs when I want to quickly/efficiently call an in-place method on each of the items contained by an iterable. (Quickly meaning the overhead of a for loop is unacceptable). A good example would be a list of sprites when I want to call draw() on each of the Sprite objects. I know I can do something like this: [sprite.draw() for sprite in sprite_list] But I feel like the list comprehension is misused since I'm not using the returned list. The same goes for the map function. Stone me for premature optimization, but I also don't want the overhead of the return value. What I want to know is if there's a method in Python that lets me do what I just explained, perhaps like the hypothetical function I suggest below: do_all(sprite_list, draw)

• What is the role of `while`-loops in computation expressions in F#?

  - by MizardX

  If you define a While method of the builder-object, you can use while-loops in your computation expressions. The signature of the While method is: member b.While (predicate:unit->bool, body:M<'a>) : M<'a> For comparison, the signature of the For method is: member b.For (items:seq<'a>, body:unit->M<'a>) : M<'a> You should notice that, in the While-method, the body is a simple type, and not a function as in the For method. You can embed some other statements, like let and function-calls inside your computation-expressions, but those can impossibly execute in a while-loop more than once. builder { while foo() do printfn "step" yield bar() } Why is the while-loop not executed more than once, but merely repeated? Why the significant difference from for-loops? Better yet, is there some intended strategy for using while-loops in computation-expressions?

• Drawing Image onto Canvas Stretches Image?

  - by Fred Finkle

  I have this code (stolen from the web): function readIt() { var reader = new FileReader(); reader.onload = (function(e) { var img = new Image(); img.src = e.target.result; var c = document.getElementById("canvas"); var ctx = c.getContext("2d"); ctx.drawImage(img, 0, 0); } ); reader.readAsDataURL(document.getElementById('userImage').files[0]); } Which works up to a point. The canvas's width and height are set to the size of the image, but only the top left of the image appears - It appears to be stretched so it fits all the space allocated to the canvas (enough to display the whole image - 615px x 615px). If I add an <img> element sized the same size as the canvas and point the src to the image in the file system it appears perfect. I'm using Chrome, but it appears the same in Firefox. Thanks in advance.

• jquery show hide div's with a href tag

  - by user1736794

  I have some jquery which reveals and hides new div's based on which button is pressed. Rather than buttons i would like to insert my own text/image and have them work in the same way, revealing and hiding the new windows. Here is the jquery: <script> $(document).ready(function(){ $(".buttons").click(function () { var divname= this.value; $("#"+divname).show("slow").siblings().hide("slow"); }); }); </script> Here is the code for one of the buttons which i would like changed to a a href tag. <input type="button" id="button1" class="buttons" value="div1"></input> Any help will be greatly appreciated. Thanks. Pia

• Why aren't my JQuery .ajax requests being made in parallel?

  - by Ryan Olson

  I am trying to make two ajax requests in parallel using jQuery like this: var sources = ["source1", "source2"]; $(sources).each(function() { var source = this; $.ajax({ async: true, type: "POST", data: {post: "data", in: "here"}, url: "/my/url/" + source, success: function(data) { process_result(data); } }); }); I got the basic structure from this question, but my requests still aren't being made in parallel. "source1" takes a while to complete, and I can see on the server that the second request isn't made until the first is completed. As far as I can tell, I don't have any other active requests, so I don't think it's a problem with the maximum number of parallel requests for the browser. Am I missing something else here?

• What's the recommended way to create an HTML elemnt and bind a listener to it using jQuery?

  - by Bytecode Ninja

  At the moment I achieve this using something like this: var myElem = "<tr id='tr-1'><td>content</td></tr>"; $("#myTable").append(myElem); $("#tr-1").click(function() { // blah blah }); Traditionally, when I wasn't using jQuery, I used to do something like this: var myElem = document.createElement(...); var myTable = document.getElementById("myTable"); myTable.appendChild(myElem); myElem.onclick = function() { // blah blah } The thing is, in the second approach I already have a reference to myElem and I don't have to scan the DOM ($("#tr-1")) to find it, like the jQuery approach, and hence it should be much faster especially in big pages. Isn't there a better jQuery-ish way to accomplish this task?

• Passing NULL values into mysql Stored procedure

  - by McNabbToSkins

  I am trying to pass a few NULL values to a stroed procedure but PHP always retains the varaibles to be empty strings '' and not NULL. My DB insert function looks like this. (I am using a Framework and ADODB so if it looks weird thats why). function insert_emp($f_name, $last_name, $dob) { if(!isset($dob)){ $dob = NULL; } $this->DB->setConnection("CALL insert_emp('$f_name', '$l_name', '$dob')"); } I have ensured that $dob is being passed an empty string ''. But for some reason when it calls the stored proc it is not changed to NULL. dob is a datetime field and mysql complains that you can not enter an empty string as a DATETIME. If I hard code the insert such as this $this->DB->setConnection("CALL insert_emp('Test1', 'Test2', 'NULL')"); it will work. Thanks for the help.

• Using a large list of terms, search through page text and replace words with links

  - by dunc

  A while ago I posted this question asking if it's possible to convert text to HTML links if they match a list of terms from my database. I have a fairly huge list of terms - around 6000. The accepted answer on that question was superb, but having never used XPath, I was at a loss when problems started occurring. At one point, after fiddling with code, I somehow managed to add over 40,000 random characters to our database - the majority of which required manual removal. Since then I've lost faith in that idea and the more simple PHP solutions simply weren't efficient enough to deal with the amount of data and the quantity of terms. My next attempt at a solution is to write a JS script which, once the page has loaded, retrieves the terms and matches them against the text on a page. This answer has an idea which I'd like to attempt. I would use AJAX to retrieve the terms from the database, to build an object such as this: var words = [ { word: 'Something', link: 'http://www.something.com' }, { word: 'Something Else', link: 'http://www.something.com/else' } ]; When the object has been built, I'd use this kind of code: //for each array element $.each(words, function() { //store it ("this" is gonna become the dom element in the next function) var search = this; $('.message').each( function() { //if it's exactly the same if ($(this).text() === search.word) { //do your magic tricks $(this).html('<a href="' + search.link + '">' + search.link + '</a>'); } } ); } ); Now, at first sight, there is a major issue here: with 6,000 terms, will this code be in any way efficient enough to do what I'm trying to do?. One option would possibly be to perform some of the overhead within the PHP script that the AJAX communicates with. For instance, I could send the ID of the post and then the PHP script could use SQL statements to retrieve all of the information from the post and match it against all 6,000 terms.. then the return call to the JavaScript could simply be the matching terms, which would significantly reduce the number of matches the above jQuery would make (around 50 at most). I have no problem with the script taking a few seconds to "load" on the user's browser, as long as it isn't impacting their CPU usage or anything like that. So, two questions in one: Can I make this work? What steps can I take to make it as efficient as possible? Thanks in advance,

• PHP multiple __autoload functions *without* the use of spl_register_autoload?

  - by Keith Palmer

  I'm an author of a growing library of PHP + QuickBooks related code. I'd like to utilize PHPs __autoload() function, however my code is a library that other people can include() into their own applications, so I can't rely on __autoload() being not already defined. Is there a way to have multiple __autoload() functions? I saw spl_autoload_register() in the PHP manual, but not all of my users have the SPL extension installed, so I can't rely on that. If there was a way to fall-back to using this and use normal require/include statements by default, I might consider that. Does anyone else have any other clever solutions to this issue? It seems like a glaring oversight to only be able to have a single __autoload() function...

• [jquery] editableText plugin enabling problem

  - by noName

  Hi, I've been experimenting with this plugin http://valums.com/edit-in-place/, so far so good... But i ran into this problem. I want to update my page when update or new request to save data is sent but if i update this function(edit-in-place) it will add second set of buttons, third, fourth and so on. How could i tell it that it would update just on that returned data, but not all elements? I have an idea it has to do something with each function of jquerys, but I'm not sure as I'm quite new to jquery. Thanks for any help!

• refactor this javascript code

  - by nathanvda

  I have two click-events, that are nearly similar, but not quite. I am wondering how to refactor them best: $('.remove_fields.dynamic').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.closest(".nested-fields").remove(); trigger_after_removal_callback(after_removal_trigger_node); }); $('.remove_fields.existing').live('click', function(e) { var $this = $(this); var after_removal_trigger_node = $this.closest(".nested-fields").parent(); trigger_removal_callback($this); e.preventDefault(); $this.prev("input[type=hidden]").val("1"); $this.closest(".nested-fields").hide(); trigger_after_removal_callback(after_removal_trigger_node); }); As you can tell there is a fair bit of overlap. I am wondering what the best/nicest way would be to refactor this code.
