如何使用可选择的 Jquery UI 查找选定的元素

2022-01-11 00:00:00 jquery jquery-plugins javascript jquery-ui

我正在寻找有关 jQuery 可选事件的事件和 ui 对象的信息:选择"和开始"作为参数.我在文档中找不到这个，循环遍历属性也无济于事.

I am looking for info on the event and ui objects the jQuery selectable events: "selecting", and "start" take as parameters. I cannot find this in the documentation and looping through the properties is no help.

$('#content_td_account').selectable({
    filter: 'li:not(".non_draggable")',
    selecting: function(event, ui) { 
    }
});

具体来说，我想找出正在选择的元素并检查它们以查看它们的父元素是否相同.我认为这将在 ui 对象中的某个位置.

Specifically I want to find what elements are being selected and check them to see if their parent elements are the same or not. I assumed this would be in the ui object some where.

推荐答案

当一个元素被选中时，它会添加 ui-selected 类.

When an element is selected it gets the ui-selected class added.

所以你可以使用 $(".ui-selected")

这可能不完全有效，但我认为这个想法是这样的:

This might not work exactly but I think the idea would be something like this:

$('#content_td_account').selectable({
  filter: 'li:not(".non_draggable")',
  selecting: function(event, ui) { 
    var p = $(this).parent();
    $(".ui-selected").each(obj, function() {
      if(obj.parent() == p) {
        // get rad
      }
    });
  }
});
