Gridstack:将小部件从一个网格拖到另一个嵌套的网格中

Gridstack: Dragging widget from one grid into another, nested one

我正在尝试创建此行为,但不确定 Gridstack 是否支持它。我有 3 个 Gridstack 网格:Grid1Grid2Grid3Grid1 是一个独立的网格,Grid3 嵌套在 Grid2 中。我需要能够将小部件从 Grid1 拖到 Grid2(外部网格)和 Grid3(嵌套网格)中。按照示例,我能够在 2 个顶级网格之间拖动小部件并创建嵌套网格,但不能将这 2 个组合在一起。如果支持 - 任何指针都将不胜感激。

注意:将代码段展开到全屏

$(document).ready(function() {
  $('.grid-stack').gridstack();
});
.grid-stack {
  background: lightgoldenrodyellow;
}

.grid-stack-item-content {
  color: #2c3e50;
  text-align: center;
  background-color: #18bc9c;
}

.grid-stack .grid-stack {
  /*margin: 0 -10px;*/
  background: rgba(255, 255, 255, 0.3);
}

.grid-stack .grid-stack .grid-stack-item-content {

Following samples I was able to drag widgets between 2 top level grids and create a nested grid, but not combining these 2 together. If this is supported

悲伤但真实,那是不可能的。至少,不是 gridstack.

此拖动机制背后的关键是由 acceptWidgets 选项完成的。但这无法处理多级 .grid-stack 元素。因此,出现错误。

您可以尝试将代码段中添加的脚本修改为如下内容:

$("#container-stack").gridstack({
   acceptWidgets: '.grid-stack-item'
})

但遗憾的是,一旦您开始拖动任何小部件,这将导致 错误。但它适用于单级嵌套,这绝对不是您要找的。

文档也没有说明任何关于嵌套级别拖动的内容。

但我认为这是不可能的原因是 issue, also this one

我想这(几乎)正是您想要的。但没有得到任何官员的回应。而且,它已经三岁了。另一个表明该项目即将结束的缺陷是,当您尝试访问他们的某些文件(例如 script)时,您会收到安全警告,这让我暂时无法添加此代码段。


因此,如果我是你,我会选择 jqueryUI 并自定义代码。


更新

这是我猜的与您预期的类似的片段,请告诉我这是否正确,然后我会再次改进它,例如添加调整大小、对齐同级小部件以及其他一些东西:

再一次, 在全屏模式下检查代码段。

$("#gridThree").draggable({
  snap: '#gridTwo',
  snapMode: 'inner',
  zIndex: 5,
  containment: 'parent'
});

$(".widgetInOne, .widgetInTwo, .widgetInThree").draggable({
  snap: '#gridOne, #gridTwo, #gridThree',
  snapMode: 'inner',
  zIndex: false,
  stack: 'div',
  cursor: 'grab',
  // grid: [ 100, 100 ]
});

$("#gridOne, #gridTwo, #gridThree").droppable({
  accept: '.widgetInOne, .widgetInTwo, .widgetInThree',
  drop: function(event, ui) {
    if ($(event.target).find($(event.toElement)).length == 0) {
      $(event.toElement).css({
        'left': '',
        top: ''
      });
      $(event.target).append($(event.toElement));
    }
  }
});

这里有一些值得注意的事情:

  • 当您将小部件拖动到网格中时,小部件元素实际上会在该网格中移动(在 DOM 结构中),因此任何依赖于父项的 css 选择器在这里可能不起作用。仅将 css 应用于小部件 class.
  • 现在小部件只捕捉到网格内边缘(而不是其他小部件的外侧),要找到更多检查:here我找不到任何其他选项但是要使用 // grid: [ 100, 100 ] 这个。

  • 此处未添加可调整大小选项,希望您可以根据需要进行调整

这是我编写的旧 drag/drop fiddle 代码(很久以前!),其中包含可拖放的区域。可以拉到任一可放置区域的项目可以再次从一个区域拖动到另一个区域并上下拖动。虽然项目的大小与您的示例中的大小不同,但它表明只需使用 jquery/jquery-ui 即可实现相同的用户体验,而无需坚持使用 gridstack。通过在电网之外工作,您可以节省一些辛苦的时间! ;)

希望对您有所帮助
