javascript/jquery: focus() not working -


I want to focus on a special ID (in roundcube) by a keyboard shortcut. Html is 

  ... div 
  
 I tried the following:  
  // strag + tab, nachchenbereich zoo commen ... and if (event.keyCode = = 9 & amp; amp; amp; and event.ctrlKey) {Warning ("Taste Errant"); //document.getElementById("messagetoolbar ") focus () .; . // $ ("# messagetoolbar") focus (); Settimesout (function ($ ('#MessageSutBarBar'). Focus (); Alert ("Zeit");}, 3000);} ...   
 First Alert and Second Alert  
  Edit:  I think I should describe it better: I want to mark the first row / roundcube Email in Email-Inbox Inbox has a table with a T-tag ... when I have your solution Try, the first line is dotted, but with the entry I can not open the mail and with the other keys I can not mark the first row / mail ... I think that to mark the first line, "one left-horizontal simulation must "...? 
 now I've tried to use jquery. Trigger inbox table html  
  & lt; table id =" messagelist " Class = "record-table messaging sort-job fix header "& Gt; & LT; thead & gt; & LT; tbody & gt; & Lt; tr id =" rcmrow27428 "class =" message "& gt; & Lt; td class =" Thread "& gt; & Lt; / Td> & Lt; td class = "date" & gt; 16.04.2014 13:41 & lt; / Td> & Lt; td class = "toto" & gt; ...   
 I tried to use ...  
  $ ('# messagelist tr'). eq (1) .addClass ('Message selected focus') removeClass ('decentralized') trigger ("click").   
 ... but it does not work: it adds a square, but does not really focus on the line :-( It works with "button"  
  Edit:  I think roundcube's file list.js is important for that question. I found the following:  
  / ** * list * / focus: function (e) {var n, id; this.focused = true; for (in this selection.) {Id = this.selection [n]; if (this.rows [id] & amp; Amp; this.rows [id] .obj) {$ (this.rows [id] .obj) .addClass ('selected'). Remov eClass ( 'unfocused');}} // already focused focusing elements (# 1,487,123, # 1,487,316, # 1,488,600, # 1,488,620) / It seems that Windowkfocus () works for all browsers but Firefox (# 1489058) $ ( 'iframe ,: focus: not (body)'). Blur (); window.focus (); if (e || (e = window.event)) rcube_event.cancel (e );},   
 Does anyone know how to modify or mention my question? Thanks!   
 
 
 Add  tabindex = 0  div to which you want to focus and you div Security will be able to set the focus using. Focus ()

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...
