JQuery Easyui Implement right-click menu dimmed not available effect _jquery

First, it is not available to implement the "All except all off" dimmed.

When you open only one tab tab, the "All except all" on the right menu should be dimmed and unavailable, which prompts the user not to have another tab in addition to this tab. The program implementation is very simple, as long as you get the number of open tab tab, if the number is 1, then the "all except all" turn gray is not available on the line.

var Tabcount = $ (' #tabs '). Tabs (' tabs '). length; Number of tab Tabs 
  if (tabcount <= 1) { 
    $ (' #mm-tabcloseother '). attr ("Disabled", "disabled"). CSS ({"Cursor": " Default "," Opacity ":" 0.4 "}); 
  else { 
    $ (' #mm-tabcloseother '). Removeattr ("Disabled"). CSS ({"cursor": "Pointer", "opacity": "1"}); 
   

Description: In the Firfox,google,opera browser, the "disabled" properties do not work, so I added a CSS style, set its transparency to make it dimmed.

Second, to implement "All off the right side of the current page" dimmed is not available.

When there is no tab on the right side of a tab tab, the Tab tab should be dimmed and unavailable. Program implementation is not difficult, as long as the title of the Last tab tab is compared with the title of the Tab tab of the current right-click menu, and if it is consistent, turn off all the "right side of the current page" to be dimmed.

var tabs = $ (' #tabs '). Tabs (' tabs ');   Get all tab tabs 
var tabcount = tabs.length The number of//tab tabs 
var lasttab = tabs[tabcount-1];//Get the last tab tab 
var LA Sttitle = Lasttab.panel (' Options '). Tab.text (); Title 
var currtab_title = $ (' #mm ') of the Last tab tab. Data ("Currtab");//title 
 
   if (Lasttitle = = Currtab_ of the current tab tab Title) { 
     $ (' #mm-tabcloseright '). attr ("Disabled", "disabled"). CSS ({"cursor": "Default", "Opacity": "0.4"}); 
   else { 
     $ (' #mm-tabcloseright '). Removeattr ("Disabled"). CSS ({"cursor": "Pointer", "opacity": "1"});

Third, the implementation of the "all off the left of the current page" dimmed is not available.

This is the opposite of the second one, get the title of the First tab tab and the title of the current tab tab to compare.

var onetab = tabs[0]; First Tab tab 
var onetitle = onetab.panel (' Options '). Tab.text ();//The title 
   if (Onetitle = = Currtab_ of the first tab tab Title) { 
     $ (' #mm-tabcloseleft '). attr ("Disabled", "disabled"). CSS ({"cursor": "Default", "Opacity": "0.4"}); 
   else { 
     $ (' #mm-tabcloseleft '). Removeattr ("Disabled"). CSS ({"cursor": "Pointer", "opacity": "1"});
