  • set the focus on the scroller when button is clicked

    - by liz
    hi i have a script <script type="text/javascript"> window.addEvent('domready', function(){ var totIncrement = 0; var increment = 560; var maxRightIncrement = increment*(-6); var fx = new Fx.Style('slider-list', 'margin-left', { duration: 1000, transition: Fx.Transitions.Back.easeInOut, wait: true }); //------------------------------------- // EVENTS for the button "previous" $('previous').addEvents({ 'click' : function(event){ if(totIncrement<0){ totIncrement = totIncrement+increment; fx.stop() fx.start(totIncrement); } } }); //------------------------------------- // EVENTS for the button "next" $('next').addEvents({ 'click' : function(event){ if(totIncrement>maxRightIncrement){ totIncrement = totIncrement-increment; fx.stop() fx.start(totIncrement); } } }) }); </script> in mootools v1.1 it makes a scroller function at the bottom of my html page. but when i click the next button the page's focus moves to the top of the page. how do i keep it on the scroller? this is the html fragment: <h3>Our Pastas</h3> <div id="slider-buttons"> <a href="#" id="previous">Previous</a> | <a href="#" id="next">Next</a&gt; </div> <div id="slider-stage"> <ul id="slider-list"> <li class="list_item"> <div id="thumbnail"><a href="xxx/product-catalog/pasta/long-pasta-in-brown-bags/bucatini"><img src="xxx/images/stories/products/_thumb1/bucatini.gif"></a></div><h4><a href="xxx/product-catalog/pasta/long-pasta-in-brown-bags/bucatini">Rustichella d'Abruzzo Bucatini</a></h4> </li> <li class="list_item"> <div id="thumbnail"><a href="xxx/product-catalog/pasta/pasta-in-trays/calamarata"><img src="xxx/images/stories/products/_thumb1/calamarata.jpg"></a></div><h4><a href="xxx/product-catalog/pasta/pasta-in-trays/calamarata">Rustichella d'Abruzzo Calamarata</a></h4> </li> <li class="list_item"> <div id="thumbnail"><a href="xxx/product-catalog/pasta/pasta-in-trays/cannolicchi"><img src="xxx/images/stories/products/_thumb1/cannolicchi.jpg"></a></div><h4><a href="xxx/product-catalog/pasta/pasta-in-trays/cannolicchi">Rustichella d'Abruzzo Cannolicchi</a></h4> </li> </ul></div>

  • jqtransform and collapsed DIV

    - by Marco
    Hello, I am using a jQuery plugin called: jqtransform This plugin uses JavaScript to apply CSS styles to form elements. The problem that I have consists in the following scenario: I’m building a search page, with a advanced search option. When the page loads, the div called “advancedSearch” is hidden, and it will only show if the user clicks a element. Inside the div#advancedSearch I have several form elements. However, if I hide the div#advancedSearch with the CSS style: “diplay:none;”, the jqtransform plugin doesn’t work correctly with the elements that are hidden. So my solution was to hide the div#advancedsearch with JavaScript. This actually works, and it does not matter if it’s done after the document is ready or not. But… with the JavaScript solution, the div#advancedSearch stays visible for a couple of milliseconds… which is visually annoying. So I was wondering if the solution to this problem would be in the CSS, or in correcting the jqtransform plugin, or even in finding a way to immediately hide the div#advancedSearch with JS making it immediately hidden. UPDATE 1 After jeerose comment I decided to place here my function (please note that the <%= % are ASP.Net tags, that I use to get the images path) $('.toggleAdvancedSearch').click(function() { $('#advancedSearchWrap').slideToggle(250); $('form.jqtransform').jqTransform({ imgPath: '<%= ResolveClientUrl("~/masterpages/img/jqtransform/") %>' }); return false; }); UPDATE 2 To test the problem, I did the following: Added another element to the page, with the ID “applyStyle”, and onClick I call the $('form').jqTransform(); Disabled the the $('form').jqTransform(); from the load of the page. If I press the a#applyStyle, before expanding the div#advancedSearch I get the same problem that I had. But if I expand the the div#advancedSearch and press the the a#applyStyle after, the problem is solved. However, if I run the page with the $('form').jqTransform(); function on the load, I cannot reapply it after with the pressing of the a#applyStyle. I think that the solution could be: disabling the all the elements that are inside the div#advancedSearch, and on the same function that expands the div, make It also apply the styles to the elements that are inside the div#advancedSearch. However, I don’t know how to do this (nether if this will work). PS: This seems to be a known issue with the plugin, but I cannot wait indefinitely for a solution.

    I am making my first Facebook App and nothing is working as stated in the documentation. As an example, I have facebook.php on my server and am calling this line: $friends = $facebook->api_client->friends_get(); but I get a "call to undefined function friends_get()" I see that there is no "friends_get()" function in the facebook.php. I do see there is a friends.get in that long array... but I'm not sure how to access it?

  • How to test if a gawk string contain a number?

    - by Tim Menzies
    In gawk I know two ways to test if a string contains a number. Which is best? Method one: using regular expressions: function method1(x) { return x ~ /^[+-]?([0-9]+[.]?[0-9]*|[.][0-9]+)([eE][+-]?[0-9]+)?$/ } Method two: the coercion trick (simpler): function method2(x) { return (x != "") && (x+0 == x) } Is there any reason to favor the more complex method1 over the simpler method2?

  • Using Visual Studio Intellisense for building jQuery selector strings

    - by jslatts
    This is a minor issue, but one I find myself running into: When I am using jQuery in Visual Studio 2010, I find myself frequently typing: $(#S using Intellisense to find the SomeID object ID: $(#SomeID).click( function() { etc.. }) then going back and adding quotes: $('#SomeID').click( function() { etc.. }) I find it annoying that if I add the quote first, Visual Studio goes into string mode and I lose Intellisense for finding the object's ID or class. Am I doing it wrong?

  • Finding the closest object in proxmity to the mouse Coordinates

    - by Cam
    Hey there, i've been working on a problem for a while now, which involves targeting the closest movieClip in relation to the x y coords of the mouse, I've attached a nice little acompanying graphic. Each mc added to the stage has it's own sub-class (HotSpots) which uses Pythag to measure distance from mouse. At this stage i can determine the closest value from my Main class but can't figure out how to reference it back to the movieclip... hope this makes sense. Below are the two Classes. My Main Class which attachs the mcs, and monitors mouse movement and traces closest value package { import flash.display.*; import flash.text.*; import flash.events.*; public class Main extends MovieClip { var pos:Number = 50; var nodeArray:Array; public function Main(){ nodeArray = []; for(var i:int = 0; i < 4; i++) { var hotSpot_mc:HotSpots = new HotSpots; hotSpot_mc.x += pos; hotSpot_mc.y += pos; addChild(hotSpot_mc); nodeArray.push(hotSpot_mc); // set some pos pos += 70; } stage.addEventListener(MouseEvent.MOUSE_MOVE,updateProxmity) } public function updateProxmity(e:MouseEvent):void { var tempArray:Array = new Array(); for(var i:int = 0; i < 4; i++) { this['tf'+[i]].text = String(nodeArray[i].dist); tempArray.push(nodeArray[i].dist); } tempArray.sort(Array.NUMERIC); var minValue:int = tempArray[0]; trace(minValue) } } } My HotSpots Class package { import flash.display.MovieClip; import flash.events.Event; import flash.text.TextField; public class HotSpots extends MovieClip { public var XSide:Number; public var YSide:Number; public var dist:Number = 0; public function HotSpots() { addEventListener(Event.ENTER_FRAME, textUp); } public function textUp(event:Event):void { XSide = this.x - MovieClip(root).mouseX; YSide = this.y - MovieClip(root).mouseY; dist = Math.round((Math.sqrt(XSide*XSide + YSide*YSide))); } } } thanks in advance

  • jquery get last ID of dynamic div

    - by Pjack
    Couldn't find an answer, but Im trying to get the last ID of the last div that was created on the page. The code I'm using doesn't seem to work using .last(). My syntax is probably wrong but I can't get it to show the ID. jQuery(document).ready(function() {jQuery("a.more_posts").live('click', function(event){ jQuery("div[id^='statuscontainer_']").last(); var id = parseInt(this.id.replace("statuscontainer_", "")); alert(id); }); });

  • Call a constructor from variable arguments with PHP

    - by zneak
    Hello guys, I have a function that takes variadic arguments, that I obtain from func_get_args(). This function needs to call a constructor with those arguments. However, I don't know how to do it. With call_user_func, you can call functions with an array of arguments, but how would you call a constructor from it? I can't just pass the array of arguments to it; it must believe I've called it "normally". Thank you!

  • Modifying multiplying calculation to use delta time

    - by Bart van Heukelom
    function(deltaTime) { x = x * 0.9; } This function is called in a game loop. First assume that it's running at a constant 30 FPS, so deltaTime is always 1/30. Now the game is changed so deltaTime isn't always 1/30 but becomes variable. How can I incorporate deltaTime in the calculation of x to keep the "effect per second" the same?

  • Save object states in .data or attr - Performance vs CSS?

    - by Neysor
    In response to my answer yesterday about rotating an Image, Jamund told me to use .data() instead of .attr() First I thought that he is right, but then I thought about a bigger context... Is it always better to use .data() instead of .attr()? I looked in some other posts like what-is-better-data-or-attr or jquery-data-vs-attrdata The answers were not satisfactory for me... So I moved on and edited the example by adding CSS. I thought it might be useful to make a different Style on each image if it rotates. My style was the following: .rp[data-rotate="0"] { border:10px solid #FF0000; } .rp[data-rotate="90"] { border:10px solid #00FF00; } .rp[data-rotate="180"] { border:10px solid #0000FF; } .rp[data-rotate="270"] { border:10px solid #00FF00; } Because design and coding are often separated, it could be a nice feature to handle this in CSS instead of adding this functionality into JavaScript. Also in my case the data-rotate is like a special state which the image currently has. So in my opinion it make sense to represent it within the DOM. I also thought this could be a case where it is much better to save with .attr() then with .data(). Never mentioned before in one of the posts I read. But then i thought about performance. Which function is faster? I built my own test following: <!DOCTYPE HTML> <html> <head> <title>test</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script type="text/javascript"> function runfirst(dobj,dname){ console.log("runfirst "+dname); console.time(dname+"-attr"); for(i=0;i<10000;i++){ dobj.attr("data-test","a"+i); } console.timeEnd(dname+"-attr"); console.time(dname+"-data"); for(i=0;i<10000;i++){ dobj.data("data-test","a"+i); } console.timeEnd(dname+"-data"); } function runlast(dobj,dname){ console.log("runlast "+dname); console.time(dname+"-data"); for(i=0;i<10000;i++){ dobj.data("data-test","a"+i); } console.timeEnd(dname+"-data"); console.time(dname+"-attr"); for(i=0;i<10000;i++){ dobj.attr("data-test","a"+i); } console.timeEnd(dname+"-attr"); } $().ready(function() { runfirst($("#rp4"),"#rp4"); runfirst($("#rp3"),"#rp3"); runlast($("#rp2"),"#rp2"); runlast($("#rp1"),"#rp1"); }); </script> </head> <body> <div id="rp1">Testdiv 1</div> <div id="rp2" data-test="1">Testdiv 2</div> <div id="rp3">Testdiv 3</div> <div id="rp4" data-test="1">Testdiv 4</div> </body> </html> It should also show if there is a difference with a predefined data-test or not. One result was this: runfirst #rp4 #rp4-attr: 515ms #rp4-data: 268ms runfirst #rp3 #rp3-attr: 505ms #rp3-data: 264ms runlast #rp2 #rp2-data: 260ms #rp2-attr: 521ms runlast #rp1 #rp1-data: 284ms #rp1-attr: 525ms So the .attr() function did always need more time than the .data() function. This is an argument for .data() I thought. Because performance is always an argument! Then I wanted to post my results here with some questions, and in the act of writing I compared with the questions Stack Overflow showed me (similar titles) And true enough, there was one interesting post about performance I read it and run their example. And now I am confused! This test showed that .data() is slower then .attr() !?!! Why is that so? First I thought it is because of a different jQuery library so I edited it and saved the new one. But the result wasn't changing... So now my questions to you: Why are there some differences in the performance in these two examples? Would you prefer to use data- HTML5 attributes instead of data, if it represents a state? Although it wouldn't be needed at the time of coding? Why - Why not? Now depending on the performance: Would performance be an argument for you using .attr() instead of data, if it shows that .attr() is better? Although data is meant to be used for .data()? UPDATE 1: I did see that without overhead .data() is much faster. Misinterpreted the data :) But I'm more interested in my second question. :) Would you prefer to use data- HTML5 attributes instead of data, if it represents a state? Although it wouldn't be needed at the time of coding? Why - Why not? Are there some other reasons you can think of, to use .attr() and not .data()? e.g. interoperability? because .data() is jquery style and HTML Attributes can be read by all... UPDATE 2: As we see from T.J Crowder's speed test in his answer attr is much faster then data! which is again confusing me :) But please! Performance is an argument, but not the highest! So give answers to my other questions please too!

  • C Programming: malloc() for a 2D array (using pointer-to-pointer)

    - by vikramtheone
    Hi Guys, yesterday I had posted a question: How should I pass a pointer to a function and allocate memory for the passed pointer from inside the called function? From the answers I got, I was able to understand what mistake I was doing. I'm facing a new problem now, can anyone help out with this? I want to dynamically allocate a 2D array, so I'm passing a Pointer-to-Pointer from my main() to another function called alloc_2D_pixels(...), where I use malloc(...) and for(...) loop to allocate memory for the 2D array. Well, after returning from the alloc_2D_pixels(...) function, the pointer-to-pointer still remains NULL, so naturally, when I try accessing or try to free(...) the Pointer-to-Pointer, the program hangs. Can anyone suggest me what mistakes I'm doing here? Help!!! Vikram SOURCE: main() { unsigned char **ptr; unsigned int rows, cols; if(alloc_2D_pixels(&ptr, rows, cols)==ERROR) // Satisfies this condition printf("Memory for the 2D array not allocated"); // NO ERROR is returned if(ptr == NULL) // ptr is NULL so no memory was allocated printf("Yes its NULL!"); // Because ptr is NULL, with any of these 3 statements below the program HANGS ptr[0][0] = 10; printf("Element: %d",ptr[0][0]); free_2D_alloc(&ptr); } signed char alloc_2D_pixels(unsigned char ***memory, unsigned int rows, unsigned int cols) { signed char status = NO_ERROR; memory = malloc(rows * sizeof(unsigned char** )); if(memory == NULL) { status = ERROR; printf("ERROR: Memory allocation failed!"); } else { int i; for(i = 0; i< cols; i++) { memory[i] = malloc(cols * sizeof(unsigned char)); if(memory[i]==NULL) { status = ERROR; printf("ERROR: Memory allocation failed!"); } } } // Inserted the statements below for debug purpose only memory[0][0] = (unsigned char)10; // I'm able to access the array from printf("\nElement %d",memory[0][0]); // here with no problems return status; } void free_2D_pixels(unsigned char ***ptr, unsigned int rows) { int i; for(i = 0; i < rows; i++) { free(ptr[i]); } free(ptr); }
