How to create fadein effect in JavaScript using for-loop and anonymous function call -


I am making a simple feedin effect using pure javascript. For this, I have tried three methods. M1 is using recursive functionality and is based on the M2 loop and anonymous function and is based on the M3 loop and string based function call . <

Under the code <1> M1 , the code is giving the right output as FEDIN effect.

But the Fidin effect does not work under M2 and

Now the Fidin effect is generated under M3 .

Can someone guide me how to produce Fadin using M2 effect for loop and anonymous function calls < / p>

M1 ------ works perfectly ------ 

  function starter () {var i = 0; Var el = document.getElementById ("div1"); Fadein (l, i); } Function feedin (L, I) {i = i + 0.01; Seto (L, I); If (i & lt; 1) {setTimeout (function () {fadeIn (L, I);}, 10);}} function set (L, I) {el.style.opacity = i; } Starter ();   
  M2  ------ does not work ------  
  function starter () { var i = 0; Var el = document.getElementById ("div1"); Fadein (l, i); } Function fadeIn (l, i) {for (i = 0; i & lt; = i; i = i + 0.01) {setTimeout (function () {seto (el, i);}, i * 1000);} } Function Set (L, I) {el.style.opacity = i; Starter ();   
 Using JSHint in JSFiddle on  M2 , it says - "Do not work within a loop"  
  M3  ------ Works appropriate ------ jsfiddle.net/TH2dn/9/  
  var i = 0; Var el = document.getElementById ("div1"); Function Feeds (for (i = 0; i & lt; = 1; i = i + 0.01) {setTimeout ("set (" + i + ")", i * 1000);}} function set (i ) {el.style.opacity = i;}   
 
 is based on the question abopve   
 
 
 
 It says - "Do not work inside the loop"   
 This is good advice, but this is not your main problem.  
 Your problem is that you are currently using every function 1 second. They will execute in a random order, starting from 1 second  Fadein (L) {var go = function (j) {setTimeout (function ()).  
 (I);}   {set (L, j);}, j * 1000);}}; (var i = 0; i & lt; i = i; Pre>

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
