html - Required Attribute Not work in Safari Browser -


I tried the following code to create the required field to notify the required field but it does not work in the Safari browser Has been doing. Code: 

  & lt; Form action = "" method = "post" & gt; & Lt; Input required / & gt; Your name: & lt; Br / & gt; & Lt; Input type = "submit" / & gt; & Lt; / Form & gt;   
 Code in Firefox  
  Can you tell me the javascript code or any workspace? New in javascript   
 thanks   
 
 
 Safari does not support it Attribute, you have to use javascript. This page contains a hacked solution that should add the desired functionality:  
  
 
  & lt; form action = "" method = "post" id = "form id" & gt; Your name: & lt; Input required = "true" /> & Lt; Br / & gt; & Lt; Input type = "submit" / & gt; & Lt; / Form & gt;   
 Javascript:  
  var form = document.getElementById ('formID'); // ID has the form: & lt; Form id = "formID" & gt; Form.noValidate = true; Form.addEventListener ('submit', function (event) {// Submit form for note if !! Event.target.checkValidity ()) {event.preventDefault (); // Dismiss default functionality warning (please, form '); // error message}}, wrong);   
 You can change the warning with a less ugly warning, such as a DIV with an error message:  
  document.getElementById ('errorMessageDiv' ) .style.display = 'block';   
 and in HTML:  
  & lt; div id = "errorMessageDiv" style = "display: block;" & Gt; Please, fill out the form. & Lt; / Div & gt;   
  (style attribute content should be in CSS file)   
 The only drawback of this approach is that this is the exact input that can be filled It is necessary that it will require a loop in all the inputs in the form and check the value (and check for better, "required" attribute presence).

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...
