如何在我点击和滑动时给td着色？

Question

我有一个测试 div 的时候，我可以把它拖到一个表格里。div 掉入标签中，我将目标颜色 <td> 蓝色的。现在，我想让所有其他的TD在我点击、按住和滑动到蓝色的右边或左边时都变成彩色的。<td> 比如调整大小。

所以我的问题是:如何 "调整 "我的蓝色的 "尺寸"。<td>"调整大小 "不是一个好词，因为我想模拟它做着色的其他人。<td> 通过点击和滑动到右边或左边，就像调整大小一样，如果你有一个线索可以遵循，我会很感激。

我试着用jquery ui resizable来放好 div 直接在 td 但我不能用它做我想要的东西（我想？

请看一下代码片段，很难解释我想从jQuery中得到什么。

预先感谢

Answer 1

这里是我建议的一个例子。由于你不能调整Cells的大小，你需要在上面铺设一些东西作为代表。请看下面的代码。

$(function() {
  // There's the gallery and the trash
  var $job = $("#testblocks"),
    $ressource = $(".ressource");

  $("div", $job).draggable({
    cancel: "a.ui-icon",
    revert: "invalid",
    containment: ".containment-wrapper",
    helper: "clone",
    cursor: "move",
    snap: "td",
    scroll: false,
    refreshPositions: true,
    drag: function() {
      var offset = $(this).offset();
      var xPos = offset.left;
      var yPos = offset.top;
      /*$('#posX').text('x: ' + xPos);
      $('#posY').text('y: ' + yPos);*/
    }
  });

  $ressource.droppable({
    hoverClass: 'hovering',
    tolerance: 'pointer',
    accept: "#testblocks > div, .ressource div",
    classes: {
      "ui-droppable-active": "ui-state-highlight"
    },
    drop: function(event, ui) {
      //$(ui.draggable).appendTo($(this));
      var i = $(this).index();
      var p = i - 1;
      var n = i + 1;
      var t = $(this);
      var r = t.parent();
      t
        .add($("td", r).eq(n))
        .add($("td", r).eq(++n))
        .add($("td", r).eq(++n))
        .addClass("marked");
      n++;

      $("<div>", {
        class: "ghost for"
      }).css({
        width: t.width(),
        height: t.height()
      }).appendTo("body").position({
        my: "left top",
        at: "left top",
        of: $(".marked:first", r)
      }).resizable({
        handles: "w",
        resize: function(e, ui) {
          if (ui.position.left < $("td", r).eq(p).position().left) {
            $("td", r).eq(p--).addClass("marked");
          }
          ui.size.width = t.width();
        }
      });

      $("<div>", {
        class: "ghost aft"
      }).css({
        width: t.width(),
        height: t.height()
      }).appendTo("body").position({
        my: "left top",
        at: "left top",
        of: $(".marked:last", r)
      }).resizable({
        handles: "e",
        resize: function(e, ui) {
          var f = ui.position.left;
          if (ui.position.left < $("td", r).eq(n).position().left) {
            $("td", r).eq(n++).addClass("marked");
          }
          ui.size.width = t.width();
        }
      });
    }
  });

  $job.droppable({
    accept: ".ressource div",
    classes: {
      "ui-droppable-active": "custom-state-active"
    },
    drop: function(event, ui) {
      $(ui.draggable).appendTo($job);
    }
  });
});

.drag {
  height: 49px;
  width: 60px;
  text-align: center;
}

td {
  border: 1px solid black;
  /*height:50px;*/
  width: 160px;
}

th {
  border: 1px solid black;
  /*height:50px;*/
  width: 180px;
}

tr {
  border: 1px solid black;
  height: 150px;
}

.basr {
  height: 150px;
}

.masterContent {
  padding: 0;
  margin: 0;
}

.marked {
  background-color: blue;
}

.ghost {
  border: 0;
  background: transparent;
}

我们使用一个类来简单地标记Cells或高亮它们。我们还添加了不属于Table的psudeo句柄。当我们调整大小时，我们可以保留大小，但只需看一下定位，以确定我们在一个方向上移动时要标记哪些单元格。
