jQuery contextmenu显示/隐藏问题

问题描述

我正在管理面板上的邮件系统"部分，并且从Outlook.com中寻找灵感.我添加了三个类似Outlook的自定义右键单击劫持菜单；

I'm working on my admin panel, the mail system section and I am finding inspiration from Outlook.com. I have added three custom right-click hijack menus alike Outlook;

  1. 右键单击邮件导航第一层
  2. 右键单击邮件导航第二层
  3. 右键单击邮件列表

对于邮件列表的右键单击，我尝试使它成为最后一个可见选项，以便在单击("DropMenu")时显示四个附加选项("ForThisSenderMore")，以使其保持不变，以便在其他位置单击菜单，除非您单击标题"或"DropMenu".

For the right-clicking of the message list, the last visible option I am trying to make it so that upon clicking ("DropMenu") the four additional options show ("ForThisSenderMore") keeping it so that click elsewhere will remove the menu unless you click on "Title" or "DropMenu".

// Trigger action when the contexmenu is about to be shown
$('ul.inbox-nav > li > a').bind("contextmenu", function(event) {

  event.preventDefault();
  $("#MailMenuFirstTier").finish().toggle(100).

  css({
    top: event.pageY + "px",
    left: event.pageX + "px"
  });
});
$('ul.inbox-nav > li > ul > li a').bind("contextmenu", function(event) {

  event.preventDefault();
  $("#MailMenuSecondTier").finish().toggle(100).

  css({
    top: event.pageY + "px",
    left: event.pageX + "px"
  });
});
$('.table>tbody>tr>td').bind("contextmenu", function(event) {

  event.preventDefault();
  $("#MailBodyList").finish().toggle(100).

  css({
    top: event.pageY + "px",
    left: event.pageX + "px"
  });
});


// If the Element is clicked somewhere
$('ul.inbox-nav > li > a').bind("mousedown", function(e) {
  if (!$(e.target).parents(".custom-menu").length > 0) {
    $("#MailMenuFirstTier").hide(100);
  }

推荐答案

这只是一个超快速的答案，我将为您进行重构/清理，但是您 几乎 .在您的$("#MailBodyList .DropMenu").click...中，您所要做的就是调用e.stopPropagation();，这可以防止click事件链接到下拉列表中(告诉用户单击某些内容时将其隐藏).

This is just a super quick answer, I'll go through and refactor / clean it up for you in a bit, but the you almost had it. In your $("#MailBodyList .DropMenu").click... all you had to do was call e.stopPropagation(); This prevents the click event from chaining up into the dropdown (which is told to hide when something is clicked). 

// Trigger action when the contexmenu is about to be shown
$('ul.inbox-nav > li > a').bind("contextmenu", function(event) {

  event.preventDefault();
  $("#MailMenuFirstTier").finish().toggle(100).

  css({
    top: event.pageY + "px",
    left: event.pageX + "px"
  });
});
$('ul.inbox-nav > li > ul > li a').bind("contextmenu", function(event) {

  event.preventDefault();
  $("#MailMenuSecondTier").finish().toggle(100).

  css({
    top: event.pageY + "px",
    left: event.pageX + "px"
  });
});
$('.table>tbody>tr>td').bind("contextmenu", function(event) {

  event.preventDefault();
  $("#MailBodyList").finish().toggle(100).

  css({
    top: event.pageY + "px",
    left: event.pageX + "px"
  });
});


// If the Element is clicked somewhere
$('ul.inbox-nav > li > a').bind("mousedown", function(e) {
  if (!$(e.target).parents(".custom-menu").length > 0) {
    $("#MailMenuFirstTier").hide(100);
  }
});
$('ul.inbox-nav > li > ul > li').bind("mousedown", function(e) {
  if (!$(e.target).parents(".custom-menu").length > 0) {
    $("#MailMenuSecondTier").hide(100);

});
$('.table>tbody>tr>td').bind("mousedown", function(e) {
  if (!$(e.target).parents(".custom-menu").length > 0) {
    $("#MailBodyList").hide(100);
  }
});

jQuery(document).click(function(event) {
