  • anonymous function variable scope [js, ajax]

    - by arthurprs
    $(".delete").click( function() { var thesender = this; $(thesender).text("Del..."); $.getJSON("ajax.php", {}, function(data) { if (data["result"]) $(thesender).remove(); // variable defined outside else alert('Error!'); } ); return false; } ); This can cause problems if user clicks on another ".delete" before the ajax callback is called?

  • Changing a Variable Out of Scope?

    - by Matrym
    Is there any way to change a variable while out of scope? I know in general, you cannot, but I'm wondering if there are any tricks or overrides. For example, is there any way to make the following work: function blah(){ var a = 1 } a = 2; alert(blah());

  • Giving my function access to outside variable

    - by brett
    I have an array outside: $myArr = array(); I would like to give my function access to the array outside it so it can add values to it function someFuntion(){ $myVal = //some processing here to determine value of $myVal $myArr[] = $myVal; } How do I give the function the right scoping to the variable?

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • Sending / Forwarding variable arguments in ObjectiveC

    - by Authman Apatira
    I know this is possible in other programming languages. Suppose we have the following arrangement: - (void) myMethod:(NSString*)variables, ... { // Handle business here. } - (void) anotherMethod:(NSString*)variables, ... { // We want to pass these variable arguments for handling [self myMethod:variables, ...]; // Do not pass GO } // Start the party: [self anotherMethod:@"arg1", @"arg2", @"arg3", @"arg4", nil]; What's the trick to get this working in ObjC?

  • JavaScript variable to ColdFusion variable

    - by Alexander
    I have a tricky one. By means of a <cfoutput query="…"> I list some records in the page from a SQL Server database. By the end of each line viewing I try to add this in to a record in a MySQL database. As you see is simple, because I can use the exact variables from the output query in to my new INSERT INTO statement. BUT: the rsPick.name comes from a database with a different character set and the only way to get it right into my new database is to read it from the web page and not from the value came in the output query. So I read this value with that little JavaScript I made and put it in the myValue variable and then I want ColdFusion to read that variable in order to place it in my SQL statement. <cfoutput query="rsPick"> <tr> <td>#rsPick.ABBREVIATION#</td> <td id="square"> #rsPick.name# </td> <td>#rsPick.Composition#</td> <td> Transaction done... <script type="text/javascript"> var myvalue = document.getElementById("square").innerHTML </script> </td> <cfquery datasource="#Request.Order#"> INSERT INTO products (iniid, abbreviation, clsid, cllid, dfsid, dflid, szsid, szlid, gross, retail, netvaluebc, composition, name) VALUES ( #rsPick.ID#, '#rsPick.ABBREVIATION#', #rsPick.CLSID#, #rsPick.CLLID#, #rsPick.DFSID#, #rsPick.DFLID#, #rsPick.SZSID#, #rsPick.SZLID#, #rsPick.GROSSPRICE#, #rsPick.RETAILPRICE#, #rsPick.NETVALUEBC#, '#rsPick.COMPOSITION#','#MYVALUE#' ) </cfquery> </tr> </cfoutput>

  • What is meant by Scope of a variable?

    - by Appy
    I think of the scope of a variable as - "The scope of a particular variable is the range within a program's source code in which that variable is recognized by the compiler". That statement is from "Scope and Lifetime of Variables in C++", which I read many months ago. Recently I came across this in LeMoyne-Owen College courses: What exactly is the difference between the scope of variables in C# and (C99, C++, Java) when However a variable still must be declared before it can be used

  • non-static variable cannot be referenced from a static context (java)

    - by Greg
    I ask that you ignore all logic.. i was taught poorly at first and so i still dont understand everything about static crap and its killing me. My error is with every single variable that i declare then try to use later inside my methods... i get the non-static variable cannot~~ error I can simply put all the rough coding of my methods inside my cases, and it works but then i cannot use recursion... What i really need is someone to help on the syntax and point me on the right direction of how to have my methods recognize my variables at the top... like compareCount etc thanks public class MyProgram7 { public static void main (String[]args) throws IOException{ Scanner scan = new Scanner(System.in); int compareCount = 0; int low = 0; int high = 0; int mid = 0; int key = 0; Scanner temp; int[]list; String menu, outputString; int option = 1; boolean found = false; // Prompt the user to select an option menu = "\n\t1 Reads file" + "\n\t2 Finds a specific number in the list" + "\n\t3 Prints how many comparisons were needed" + "\n\t0 Quit\n\n\n"; System.out.println(menu); System.out.print("\tEnter your selection: "); option = scan.nextInt(); // Keep reading data until the user enters 0 while (option != 0) { switch (option) { case 1: readFile(); break; case 2: findKey(list,low,high,key); break; case 3: printCount(); break; default: outputString = "\nInvalid Selection\n"; System.out.println(outputString); break; }//end of switch System.out.println(menu); System.out.print("\tEnter your selection: "); option = scan.nextInt(); }//end of while }//end of main public static void readFile() { int i = 0; temp = new Scanner(new File("CS1302_Data7_2010.txt")); while(temp.hasNext()) { list[i]= temp.nextInt(); i++; }//end of while temp.close(); System.out.println("File Found..."); }//end of readFile() public static void findKey() { while(found!=true) { while(key < 100 || key > 999) { System.out.println("Please enter the number you would like to search for? ie 350: "); key = scan.nextInt(); }//end of inside while //base if (low <= high) { mid = ((low+high)/2); if (key == list[mid]) { found = true; compareCount++; }//end of inside if }//end of outside if else if (key < list[mid]) { compareCount++; high = mid-1; findKey(list,low,high,key); }//end of else if else { compareCount++; low = mid+1; findKey(list,low,high,key); }//end of else }//end of outside while }//end of findKey() public static void printCount() { System.out.println("Total number of comparisons is: " + compareCount); }//end of printCount }//end of class
