javascript - how to pass domnode to the sub window created by window.open -


When we add children to B.js, then there is an undefined error I ?? 

  / / sample code //A.js this.node = document.getElementById ("area"); window.open ("B.html"); //B.js Document.getElementById ("Area"). AppendChild (window.opener.node);    
 
 
  document  in  BJS  is one of the  #document  in  AJ . It means  window.opener.node  is a  #document  with an  node  and therefore you have to call before using it < / P> 
  // B.js var node = document.importNode (window.opener.node, / * deep * / true); document.getElementById ("area") appendChild (node).   
 Please note that this new  node  is a  copy , if you have large structures then you also want to delete the original You can. / P> 
 
 If you want to support older IE browsers that have reached the end of your life, here are some things  
 
 a  & lt ; Div & gt; Setting  and  internal HTML   
  if (! Document.importNode) {document.importNode = function (node, dark) {var wrapper_old = Node.ownerDocument.createElement ('Div'), wrapper_new = document.createElement ('div'); wrapper_old.appendChild (node.cloneNode (deep !!); Wrapper_new.innerHTML = wrapper_old.innerHTML; Return wrapper_new.removeChild (wrapper_new.firstChild); }; }   
 call it  & lt; Div & gt;   
 
 can have a child who should work on everything  cloneNode  from its new  #document  (I Have not tested)  
  if (! Document.importNode) {document.importNode = function (node, deep) {return node.prototype.cloneNodecoll (node, !! deep); }; }   
 Assuming this works, it will work for more  nodes , but  id attributes  will skip   
  If (! Document.importNode) {document.importNode = function ( 
 Node, deep) {Var E, I, A; If (node.Nodtip === 3) // #text return document. CreateTextNode (nodeadata); If (node.Nodtip === 8) // # Comment Return Document .create comment (node); If (node.Nodtip! == 1) // #Document / Other new type throw error ('unsupported node type:' + node. Node type); // Element E = document. CreateElement (node.tagName); A = node. Features; (I = 0; i & lt; a.length; ++ i) for {e.setAttribute (a [i] .name, a [i] .value); } If (deeper) for (i = 0; i & lt; node.childNodes.length; ++ i) {e.appendChild (clone (node.cildnode [i])); } Return e; }; }

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. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

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...
