why can't i change this div's innetHTML with ajax? -


Just started learning AJAX today and fell on the first stage, the worst part is, what I really can not find With the code, can you see it?

The internal HTML of the device should be converted into a response. Text within the data.txt. The text inside of this file is "Hey man" (cuz no hello world does not like) 

   & Lt; / Head & gt; & Lt; Body & gt; & Lt; div id = "hehe" & gt; Ha ... We are here, this will be an Ajax performance! & Lt; / Div & gt; & Lt; / Body & gt; & Lt; script src = "script.js" & gt; & Lt; / Script & gt; & Lt; / Html & gt;   
 javascript  
  var request = new XMLHttpRequest (); Request.open ('receive', 'data.txt'); Document.onreadystatechange = function () {if ((this.readyState === 4) & amp; (this.status === 200)) {document.getElementById ('hehe'). InnerHTML = request.responseText; }}; Sent request ();   
 Thanks in advance!  
 
 
  use the request Onreadystatechange  not  document.onreadystatechange .

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...
