var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $("body").on("contextmenu", "table tbody button", function(e) {
    $(".contextMenu").hide();
    $(this).parent().find('.contextMenu').css({
      display: "block",
      left: e.pageX,
      top: e.pageY
    });
    return false;
  });
  $(".contextMenu").on("click", "a", function() {
    $(this).hide();
  });

  $("html").click(function() {
    $(".contextMenu").hide();
  });
  $scope.nodes = [{
      "id": 228,
      "name": "Folder 1",
      "descr": "",
      "path": "227/",
      "mm": true
    },
    {
      "id": 229,
      "name": "Folder 2",
      "descr": "",
      "path": "227/",
      "mm": true

  $scope.deleteFolder = function(detailid) {
    console.log(detailid);
    alert(detailid)

.contextmenustyle {

有人可以建议我在上下文菜单的CSS中应该更改什么，这样即使列表更大，我也能看到菜单。 当列表较小时，它对我来说很好。附上图片。 红线显示我点击的位置以及实际弹出菜单的位置。

.contextMenu {
  position: fixed;
  display:none;
}
.contextmenustyle
{
    display:block;position:static;margin-bottom:0px;
}

Answer 1

如果你是分享完整代码，我可以帮助你

试试这个。

.contextMenu {
  position: relative;
  display:none;
}
.contextmenustyle
{
    display:block;position:absolute;margin-bottom:0px;
}
