javascript - 拖动后元素变得随机不可调整大小

转载 作者：行者123 更新时间：2023-11-29 21:36:37 24 4
gpt4 key购买 nike

选中并拖动多个元素后，其中一些不再可调整大小:调整大小图标从右上角消失。

可调整大小的图标保留在旧位置并且不会移动移动的元素。

要重现，请运行下面的代码，使用套索选择所有元素并拖动所选元素。之后，调整大小图标从随机元素中消失，这些元素不再可拖动。

如何解决这个问题？

我试图通过添加来解决这个问题

$(".designer-verticalline, .designer-rectangle, .designer-field, .designer-image").resizable();

drag() 方法结束，但问题仍然存在

最佳答案

问题是可调整大小的图标也是可选择的，所以当您将它们包含在套索中时，它们会被选中，并且它们的 top 和 left 会在您更改时更改拖动。

Selectable 有一个 filter option 允许指定哪些元素应该是可选的。通过将其设置为 '.designer-field' 它应该可以解决问题。

$(".designer-panel-body").selectable({
    filter: '.designer-field'
});
