单击并滑动时如何为 td 着色？

Question

我有一个测试 div，当 div 被放入选项卡时，我可以将其拖入 table，我将目标 <td> 着色为蓝色。现在我想让所有其他的 td beeing 在我点击、按住并向右或向左滑动蓝色的 <td> 时像调整大小一样变色。

所以我的问题是：如何"resize"我的蓝<td>？ "Resize" 不是一个好词，因为我想模拟它为其他 <td> 着色，方法是单击并向右或向左滑动，就像调整大小一样，如果你有一个 clue/way 跟随我会很感激的。

我尝试使用 jquery ui resizable 将 div 直接放在 td 中，但我不能用它做我想要的（我想?)

请看一下代码片段，很难解释我想从 jQuery 得到什么。

Answer 1

这是我建议的一个例子。由于您无法调整单元格的大小，因此您需要放置一些东西来充当代表。考虑以下代码。

$(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;*/

tr {

.basr {

.masterContent {
  padding: 0;

.marked {

.ghost {

我们使用 Class 来简单地标记单元格或突出显示它们。我们还添加了不属于 Table 的伪句柄。当我们调整大小时，我们可以保留大小，但只需查看定位以确定当我们朝一个方向移动时要标记哪些单元格。
