如何通过jQuery禁用文本选择？

$("body").css("-webkit-user-select", "none");
$("body").css("-moz-user-select", "none");
$("body").css("-ms-user-select", "none");
$("body").css("user-select", "none");

function disableTextSelection() {
  document.body.addEventListener("mousedown", function(event) {
    if (event.ctrlKey) {
      event.preventDefault();
    }
  });
}

disableTextSelection();

$(document).on("mousedown", function(event) {
  if (event.ctrlKey) {
    event.preventDefault();
  }
});
