把某個彈出DIV放置在滑鼠旁邊

place_a_popup_div_next_to_mouse_cursor.js

//You can try:

$( "td").click( function(event) {
  $("#divId").css( {position:"absolute", top:event.pageY, left: event.pageX});
});

//After additional question was asked in the comment:

$( "td").click( function(event) {
  var div = $("#divId");
  div.css( {
      position:"absolute", 
      top:event.pageY, 
      left: event.pageX});

  var delayTimer = setTimeout( function( ) {
        $that.fadeIn( "slow");
     }, 100);

  div.mouseover( function( event) {
     if (delayTimer)
         clearTimeout( delayTimer);
  }).mouseout( function(){
     if (delayTimer)
         clearTimeout( delayTimer);
     var $that = $(this);
     delayTimer = setTimeout( function( ) {
        $that.fadeOut( "slow");
     }, 500)         
  });
});
