    $contextMenu.css({
      display: "block",
      left: e.pageX,
      top: e.pageY
    });
    console.log($(this));
    return false;
  });

Answer 1

Use $(e.target) for jquery object representing clicked element. Otherwise just use e.target for plain old javascript dom element.

In your case, to alert the column text, try this code:

$(function() {

  var $contextMenu = $("#contextMenu");

  $("body").on("contextmenu", "table tr", function(e) {
    $contextMenu.css({
      display: "block",
      left: e.pageX,
      top: e.pageY
    });
    alert($(e.target).text());
    return false;
  });

  $contextMenu.on("click", "a", function() {
     $contextMenu.hide();
  });

});

首先使用TR> TD选择器

$("table tr >td").on("contextmenu", function(e) { alert($(this).text()); //rest of the statements goes here });

Answer 3

Internet Explorer introduced element.innerText , other browsers use element.textContent .

$(function() {
    $("body").on("contextmenu", "table tr", function(e) {
        var target = e.target.parentElement;
        var text = target.innerText || target.textContent;
        alert(text);
        return false;
    });
});
