jQuery UI Sortable表和单元格在拖动tr时正在缩小 [英] jQuery UI Sortable table and cell is shrinking while dragging tr

问题描述

在拖动时面临两个问题.

While dragging am facing two issues.

1. 表当我有一个隐藏的td时，它会自我缩小.
2. 被拖曳的tr单元格(td)正在缩小

1. table it self is shrinking when i have a hidden td.
2. dragged tr cell(td)s are shrinking

这是可排序的代码:

$('tbody').sortable({
    items: ">tr",
    appendTo: "parent",
    opacity: 1,
    containment: "document",
    placeholder: "placeholder-style",
    cursor: "move",
    delay: 150,
});

推荐答案

缩小表的问题是因为您有一个隐藏的单元格(在sortable为您创建的占位符中有5个单元格，没有一个是隐藏的. 您可以通过在拖动开始后将placeholder内的第二个td设置为隐藏来解决此问题:

The problem with the shrinking of the table is because you have a hidden cell (and in the placeholder that the sortable creates for you there are 5 cells and non of them are hidden. You can fix this by setting the 2nd td inside the placeholder as hidden once you start the drag:

$(this).find('.placeholder-style td:nth-child(2)').addClass('hidden-td')

第二个问题是由于您拖动的tr已更改为position: absolute而不再具有表的属性所致.您可以通过在该行上设置display: table来解决此问题:

The second problem is caused by the fact that the tr that you drag was changed to position: absolute and it is no longer have the properties of the table. You can fix this by setting display: table to that row:

ui.helper.css('display', 'table')

排序完成后，必须撤消此更改.

This change must be un-done when the the sorting is done.

这是完整的更改:

start: function(event, ui) {
    $(this).find('.placeholder-style td:nth-child(2)').addClass('hidden-td')
    ui.helper.css('display', 'table')
},
stop: function(event, ui) {
    ui.item.css('display', '')
}

这是一个可行的例子

$('tbody').sortable({
  items: ">tr",
  appendTo: "parent",
  opacity: 1,
  containment: "document",
  placeholder: "placeholder-style",
  cursor: "move",
  delay: 150,
  start: function(event, ui) {
  	$(this).find('.placeholder-style td:nth-child(2)').addClass('hidden-td')
    ui.helper.css('display', 'table')
  },
  stop: function(event, ui) {
  	ui.item.css('display', '')
  }
});
