  • function_exists php

    - by user527800
    Hi all I'm trying to write a function that could receive it's second arg a name of a function. In order to validate function's name (that will be used in an eval statement) I use function_exists such as: if(function_exists($type)){ $toEval= $type.'(\''.$file.'\');'; }else{ But if the arg sent is include or require (with 'once' variations) this code fails (function_exists returns false). How could this be fixed? Thanks, Alex

  • Getting an Ajax response from Zend Framework Controller

    - by JavaLava
    I'm doing an Ajax request on one of my views to a Controller but I am unable to send back a response to the Ajax method. In the snippet below, I am trying to send the word 'hellopanda' back but in the alert message, I'll get data as an object. View : $.ajax({ type: "POST", url: "localhost/some-activity", data: dataString, success: function(data) { alert( "Data is: " + data); //do something with data }, error: function(data){ alert( "Data is: " + data); //do something with data }, onComplete: function(){ } }); Controller: public function someActivityAction(){ //do stuff echo "hellopanda"; } I'm pretty sure the echo is the problem. Any insights on to how to do a proper response to the view would be greatly appreciated.

    var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.

  • How to find where error is.

    - by gurugio
    How can I find where the error occurs? In C language, the return value means what error occurs, such as failure to open file or memory allocation. There is no information where the error occurs. For example, function 'foo' calls A,B,C,D. If foo returns an error value, it might be return value of A or B or C or D. I cannot find what function returns error. I have to run debugger or add some codes to find what function returns error.

  • If item not in the lst in scheme

    - by ms. sakura
    I'm working on context-free grammars, and I have a function that returns the (terminal values of grammar) for example: i have non-terminal function that results in (A B) , from calling say ((A cat) (B happy np) (A B sad)) so technically A and B are non terminals of the grammar. Now I want to be able to get the terminals (cat happy np sad) (define terminals (lambda (lsts) (cond ((null? lsts) lsts) ((not(member? (car(car lsts)) (n-terminals lsts))) (cons (car(car lsts)) (terminals (car (cdr lsts))))) (else (terminals (cdr lsts)))))) PS: functionality of n-terminals is described above. member? is a boolean function that returns true if an item is a member of the list, false otherwise. My function returns an empty lst. What am I missing here?

  • Is this a safe way to reference objects in JavaScript?

    - by John
    If I were to define two objects myDataStore and myDrawer something like this: var myDataStore = function(myObjectRef) { this.myInternalObject = myObjectRef; }; var myDrawer = function(myObjRef) { this.myInternalObject = myObjectRef; }; And if I were to create an object like so: (function(){ var myObject = window.myObject = function(){ this.dataStore = new myDataStore(this); this.drawer = new myDrawer(this); } })(); Then myObject.dataStore.myInternalObject, and myObject.drawer.myInternalObject, would simply be pointers back to the original 'myObject' - not taking up any additional memory in the browser. Yes? I am interested in implementing techniques like this - as it makes it easy for objects to communicate with each other.

  • Return from jQuery Ajax Method

    - by Lijo
    I have a button named searchReportButton. On this button click, I need to check session value from server using a ajax web method "Error.aspx/CheckSessionExpiry".This is done in checkSession javascript function. The checkSession is not returning anything now - instead it is handling the required operation based on the result (redirecting to error page). I need to return the result of ajax web method to the Main Caller. How can we do this return? Main Caller searchReportButton.click(function () { checkSession(); //Remainging Code }); Helper function checkSession() { var win = 101; $.ajax( { type: "POST", url: "Error.aspx/CheckSessionExpiry", data: '{"winNumber": "' + win + '"}', contentType: "application/json; charset=utf-8", dataType: "json", success: handleSessionResult } ); } Result Helper function handleSessionResult(result) { if (result.hasOwnProperty("d")) { result = result.d } if (result == "ACTIVE") { window.location.href("Error.aspx"); return false; } //alert(result); }

  • Check for changes with jquery and a database

    - by Steve
    I am doing a notification system. When a new post is published, users will be notified immediately by an small notification on the screen. I am currently using this: setInterval(function(){ checkForChanges(); }, 2*1000); function checkForChanges(){ $.post("http://"+ document.domain + "/posts/checkForChanges/", function(dat){ if(dat>0){ .... /*create notification*/ } }); } And i was wondering if this is the correct way to do it or not. Because, this is calling a PHP function every 2 seconds and making a query to the database. In case there are no new changes, it won't do anything... Thanks.

  • Getting Results from a Web SQL database

    - by andrew8088
    I'm playing around with the new Web SQL databases. Is there a way to return results from a SELECT statement? Here's my example: function getTasks (list) { db.transaction(function (tx) { list = list || 'inbox'; tx.executeSql("SELECT * FROM tasklist WHERE list = ?", [list], function (tx, results) { var retObj = [], i, len = results.rows.length; for ( i = 0; i < len; i++ ) { retObj[i] = results.rows.item(i); } return retObj; }); }); } The getTasks function is returning before the success callback does; is there a way to get the results out of the executeSql method, or do I have to do all the processing within the callback?

  • Fade out menu doesn't work in IE8

    - by user1787488
    I used this script in my website. But it doesn't work in IE8 or lower versions. Is it possible to work perfectly in all browsers? <script type="text/javascript" src="/web/upload/js/jquery-1.3.2.js"></script> <script type="text/javascript"> $(function() { $(window).scroll(function(){ var scrollTop = $(window).scrollTop(); if(scrollTop != 0) $('#header').stop().animate({'opacity':'0'},400); else $('#header').stop().animate({'opacity':'1'},400); }); $('#header').hover( function (e) { var scrollTop = $(window).scrollTop(); if(scrollTop != 0){ $('#header').stop().animate({'opacity':'1'},400); } }, function (e) { var scrollTop = $(window).scrollTop(); if(scrollTop != 0){ $('#header').stop().animate({'opacity':'0'},400); } } ); }); </script>

  • Prototype with a callback problem

    function Foo() { this.bar = false; } Foo.prototype={ onLoad: function() { this.bar=true; }, create: function(id) { SomeClass.someMethod({ id: id, onWorkIsDone: this.onLoad }); } }; var temp=new Foo(); temp.create(); This sample has a logic error in string 'onWorkIsDone: this.onLoad'. What I have to place instead of 'this.onLoad' to make SomeClass call exactly the temp.onLoad method when it finishes it's work?

  • Obtaining frame pointer in C

    - by assketchum
    I'm trying to get the FP in my C program, I tried two different ways, but they both differ from what I get when I run GDB. The first way I tried, I made a protocol function in C for the Assembly function: int* getEbp(); and my code looks like this: int* ebp = getEbp(); printf("ebp: %08x\n", ebp); // value i get here is 0xbfe2db58 while( esp <= ebp ) esp -= 4; printf( "ebp: %08x, esp" ); //value i get here is 0xbfe2daec My assembly code getEbp: movl %ebp, %eax ret I tried making the prototype function to just return an int, but that also doesn't match up with my GDB output. We are using x86 assembly. EDIT: typos, and my getEsp function looks exactly like the other one: getEsp: movl %esp, %eax ret

  • Why are interfaces unusable in PHP?

    - by streetparade
    I mean an interface definition without defining the return type makes it unusable? This makes more Clear Interface run { public function getInteger(); } class MyString implements run { public function myNumber() { } public function getInteger() { return "Not a number"; } } In Java every Interface has a return type like Integer,String,Void I know that PHP is unfortunately a loosly typed Language but isnt there a Solution for that Problem? Is it Possible to defining a Interface with a Return type like Integer?

  • how to generate uncorrelated random numbers in repeated calls in parallel?

    - by user1446948
    I want to write a function which will be repeatedly called by other functions many times. Inside this function it is supposed to generate a lot of random numbers and this part will be treated in parallel. If only for one run, the seed can be chosen differently for each thread, so that the random numbers will be uncorrelated. However, if this function will be called the 2nd time, it seems that the random numbers will repeat unless the seed will be again changed during the later calls. So my question is, is there a good way to generate the random numbers or reset the seed so that the random numbers generated by repeated calls to this function and also by different threads are really random? Thank you.

  • Javascript Image object without instantiating

    - by user276027
    This question is about javascript performance. Consider 3 examples for illustration: function loadImgA() { new Image().src="http://example.com/image.gif" } function loadImgA1() { Image().src="http://example.com/image.gif" } function loadImgB() { var testImg = new Image(); testImg.src="http://example.com/image.gif" } Now the point is I don't really need to manipulate the the image object after it was created, hence loadImgA(). The question is, what happens if nothing is assigned to the return value of the new Image() constructor - in that case I can actually skip the 'new' keyword as in loadImgA1()? Does the object then live outside the function or somehow affects memory usage? Other implications, differences? I reckon not, as no real instance was actually created? To put this into perspective, I only need to get the http request for image through. No preloading or other advanced image manipulation. What would be the preferred method from the above?

  • $.each - wait for jSON request before proceeding

    - by GaaayLooord
    I have an issue with the below code: the jQuery.each is speeding on without waiting for the JSON request to finish. As a result, the 'thisVariationID' and 'thisOrderID' variables are being reset by the latest iteration of a loop before they can be used in the slower getJSON function. Is there a way to make each iteration of the the .each wait until completion of the getJSON request and callback function before moving on to the next iteration? $.each($('.checkStatus'), function(){ thisVariationID = $(this).attr('data-id'); thisOrderID = $(this).attr('id'); $.getJSON(jsonURL+'?orderID='+thisOrderID+'&variationID='+thisVariationID+'&callback=?', function(data){ if (data.response = 'success'){ //show the tick. allow the booking to go through $('#loadingSML'+thisVariationID).hide(); $('#tick'+thisVariationID).show(); }else{ //show the cross. Do not allow the booking to be made $('#loadingSML'+thisVariationID).hide(); $('#cross'+thisVariationID).hide(); $('#unableToReserveError').slideDown(); //disable the form $('#OrderForm_OrderForm input').attr('disabled','disabled'); } }) })

  • Jquery load() loading more than I want...

    - by Probocop
    Hi, I am trying to load just the contents of a <div> into another <div> on the same page using a jquery function. But when the function triggers, it loads the entire <HTML> document into the specified <div>. Any idea why it would be doing this? My code is as follows: Jquery: function button1() { $('#sidebar-content').fadeOut(function() { $(this).load('#button1').fadeIn(); }); } function button2() { $('#sidebar-content').fadeOut(function() { $(this).load('#button2').fadeIn(); }); } HTML: <div id="content-holder"> <div id="main-content" class="float-holder"> <div id="inner"> <h1>BRAND TRUTH</h1> <div id="flashcontent"> <div id="button1"> <div id="content"> <h1>Brand Truth</h1> <p>What this basically means is our way of working, the process involved by both ourselves and our client.</p> <p>When the truth wheel process is followed, the end result is so much stronger.</p> </div> </div> <div id="button2"> <div id="content"> <h1>Button 2 Content</h1> <p>Some other content</p> <p>Some other content x2</p> </div> </div> </div> <script type="text/javascript"> // <![CDATA[ var so = new SWFObject("working.swf", "working", "400", "400", "9", "#FFFFFF"); so.write("flashcontent"); // ]]> </script> </div> <div id="sidebar"> <div id="sidebar-content"> Replace Content Here! </div> </div> </div><!-- end #main-content --> </div><!-- end #content-holder -->
