php - JavaScript error in function which calcs sum of two values -


This is my JS code to match two digits 

   script type = "text / javascript" & gt; Function match () {var a = parseInt (document.getElementById ("a")); Var b = parseInt (document.getElementById ("two")); Var c = parseInt (document.getElementById ("sum")); var d; D = a + b; If (D! = C) {Warning ("something is wrong !!"); } And {warnings ("success"); }} & lt; / Script & gt;   
 To generate the HTML code two digits and check this process.  
  & lt; form action = "#" method = "post" onsubmit = "return match ();" & gt; & Lt; input type = "text" name = "one" id = "one" value = "& lt ;? php echo rand (1,9);?> & gt; Read-only = "Read-only" /> + & lt; Input type = "text" name = "two" id = "two" value = "& lt ;? php echo rand (1,9);?> & Gt;" Read-only = "Read-only" /> = & Lt; Input type = "text" name = "yoga" id = "sum" /> & Lt; Input type = "submit" value = "submit" /> & Lt; / Form & gt;    
 
 
 Maybe you want them to be assessed and not just elements.  
  var a = parseInt (document.getElementById ("a"). Value, 10); var b = parseInt (document.getElementById ("two"). value, 10); var c = parseInt (document.getElementById ("sum") value, 10);   
 Additionally, when you are using  parseInt ()  then provide  radix  otherwise it may sometimes be crazy is.

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.

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...
