javascript - Making element referencing less clunky -


I'm new to JavaScript so please forgive me if this is a simple answer. I can not know that I have a small section of the script that changes the text based on the content of the paragraph. Very easy. My question is, why do I have to complete the entire context twice? Does the variable not point to the same thing? Is there an easier way?

This works: 

  & lt; P id = "name" & gt; Electric City & lt; / P & gt; & Lt; Script type = "text / javascript" & gt; Var name = document.getElementById ("name"). InnerHTML; If (name == "electric city") {document.getElementById ("name"). InnerHTML = "Welcome!"; } & Lt; / Script & gt;   
 It is not:  
  & lt; P id = "name" & gt; Electric City & lt; / P & gt; & Lt; Script type = "text / javascript" & gt; Var name = document.getElementById ("name"). InnerHTML; If (name == "Electric City") {name = "Welcome!"; } & Lt; / Script & gt;   
 Thanks!   
 
 
  var name = document .getElementById ("name") innerHTML.   
 That line of code gets  value  from your "name" element (using its  innerHTML  property) and its variable Copies in  names . The  name  variable does not reference the "name" element.  
 If you want to simplify your code, then you can do something like this:  
  & lt; script type = "text / javascript" & gt; Var name element = document.getElementById ("name"); If (nameElement.innerHTML == "Electric City") {nameElement.innerHTML = "Welcome!" ;; } & Lt; / Script & gt;

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...
