javascript - JS autofill incremented score, edit previous fill in -


OK I wrote JS that input is filled automatically with digits incremented when adding score . Works fine how do I get this fact that if someone goes back to edit the previous input, it first decreases the value and then increases the correct number and adds it to the score.

How do I check ... Is it any editing on the input or just an input?

is below: 

  var score = 0; Function Checkfield (Val, ECSR) {Score = + + + + + VAL; Document.getElementById ('incr' + inscr) .value = score; } You can add scores of each field to each change with JQuery (

Not tested)): 

  & lt; Input name = "ex1" class = "inputline1" /> & Lt; Input name = "ex2" class = "inputline1" /> & Lt; Input name = "ex3" class = "inputline1" /> & Lt; Input name = "result-1" id = "result-1" />

and in your JS: 

  $ (document) .ready (function () {$ (".inputline 1"). Changes (function ( Val ($ ("# result-1"). Val (0); $ ("inputline1") each (function () {$ ("# result-1"). Val ($ ("# result-1" ) .val () + $ (this) .val ());}}})

In this code: We will reset the result values ​​for all fields of line 1 and the class Add value of each input with inputline1.

Have fun!

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
