javascript - Jquerymobile select menu disable options -


Hi, I'm getting a hard time doing this job, in my jquery mobile app, I have 3 option menus There are general options in the menu, the code is below 

  & lt; Select class = "mySelect4" data-corner = "wrong" id = "objective1" & gt; & Lt; Option value = 1> Select & lt; / Options & gt; & Lt; Option value = 2> Generated & lt; / Options & gt; & Lt; Option value = 3> Increase & lt; / Options & gt; & Lt; Option value = 4> Increasing customer engagement & lt; / Options & gt; & Lt; / Select & gt; & Lt; Select class = "mySelect5" data-corners = "wrong" id = "objective2" & gt; & Lt; Option value = 1> Select & lt; / Options & gt; & Lt; Option value = 2> Generated & lt; / Options & gt; & Lt; Option value = 3> Increase & lt; / Options & gt; & Lt; Option value = 4> Increasing & lt; / Options & gt; & Lt; / Select & gt; & Lt; Select class = "mySelect6" data-corners = "wrong" id = "objective3" & gt; & Lt; Option value = 1> Select objective 3 & lt; / Options & gt; & Lt; Option value = 2> Generated & lt; / Options & gt; & Lt; Option value = 3> Increase & lt; / Options & gt; & Lt; Option value = 4> Increasing & lt; / Options & gt; & Lt; / Select & gt;   
 If the user chooses an option in the Fist selection menu, then the option should be disabled in two other menus. Any idea or solution is appreciated   
 
 
  $ ('# purpose1'). Change (function () {var value1 = $ (this) .val (); $ ('each (function () (if ($ (this) .val () == value 1) {$ (this) .attr ( "Disabled", "disabled");}});});   
 and select the objective 2 and objective 3 box  
 I hope it

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...
