Question

我有四种选择的环境菜单,我想在点击后隐藏或去掉一种选择。这些是我的文字碎片。在我点击“挽救方案”之后,每当我右边再次点击时,我只想在地表上提供“Move”方案。 drag是干类。是可能的?

var menu = [
            { Move :function(menuItem,menuObject){
                    $(this).css({ backgroundColor : red });
                    return true; 
                } 
            },
            { Save :function(menuItem,menuObject){
                    $(this).css({ backgroundColor : blue });
                    return true;
                }
            }
        ];

$(function() {
            $( .drag ).contextMenu(menu,{
                showSpeed:500,
                hideSpeed:500,
                showTransition: fadeIn ,
                hideTransition: fadeOut 
            });
        });

First of all the class drag is the class of the parent element. So you have to find the class of the "save" element. Lets suppose the class is .save, then on click remove it. This is done with this code:

$(".save").click(function{
 $(this).remove();
})

如果你再次点击,该要素将再次建立,上述职能将失去目的。正如我能看到的那样,这是你的问题。

但是,为什么在“挖掘”之后,你需要藏匿的纽子? 或许用户希望再次储蓄。

如果我们能看到一种mo,了解你试图执行的东西,那将是有益的。

If you try to apply a rule only on changed (dragged) element you have to flag the changed ones in the class or in your db which holds the positions of the elements. Then you can manipulate only the flagged (changed) through the jquery selector.

if ((.drag).hasClass( .changed )){
  $(".save").css({"visibility: visible"});
}

不要忘记不实地隐藏在 c中。

.save{visibility: none}
