html - Is there a way to ONLY allow input using the spinner controls on an input type="number"? -


I want the user to be able to change the contents of the box with only in HTML5 Spinner available with input type = "number" , and not able to type anything in the box 

     
 Can I do this?  
 (My intent viewers are using Chrome only, so spinners are not visible on IE (9) and Firefox (13))   
 < Div class = "post-text" itemprop = "text"> 
 You can use the javascript  onkeydown  event ... which will prevent the user from typing anything, and still He will be able to use the arrow controls to increase and decrease the numbers.  
  & lt; Input type = "number" min = "0" value = "0" phase = "5" onkeydown = "return false" /> Note: Just do not depend on Javascript and HTML, it is always to ensure that the server side does not authenticate that the user does. Posted to a malicious input Javascript can be disabled and user can abuse by adding any text in the text box, but there is no other way you can prevent it, so check the server side too.  
 
 As you commented, you would like to disable text selection, so that users are not confused, you can also use CSS positioning techniques here as you said that the desired user only Chrome does not have a lot of problems, so you can do something like this ...  
    
  Input  element  span  element, and just css positioning technique and  after:  pseudo With, we overlay a virtual element on  input .  
 Now I've put out the settings for demonstration purposes only, you can safely remove them.

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...
