拖动后元素变得随机不可调整大小 [英] Elements became randomly non-resizable after dragging
本文介绍了拖动后元素变得随机不可调整大小的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
选择并拖动多个元素后，其中一些不再可调整大小:调整大小图标从右上角消失.
After multiple elemens are selected and dragged, some of them are no more resizable: resize icon disappear from right corner.
可调整大小的图标保留在旧位置，并且不会移动已移动的元素.
Resizable icon remains in old place and does not move which moved elements.
要重现，请在下面运行代码，使用套索选择所有元素，然后拖动选定的元素.之后，调整大小的图标会从随机元素中消失，而这些元素将不再是可拖动的.
To reproduce, run code below, select all elements using lasso and drag selected elements. After that resize icon disappers from random elements and those elements are no more draggable.
如何解决此问题?
我试图通过添加来解决此问题
i tried to fix this by adding
$(".designer-verticalline, .designer-rectangle, .designer-field, .designer-image").resizable();
到drag()方法的结尾，但问题仍然存在
to end of drag() methos but problem persists

推荐答案
问题在于可调整大小的图标也可以选择，因此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拖动时更改.
The problem is that the resizable icons are selectable as well, so when you include them in the lasso, they are selected and their top and left are changed when you drag.
Selectable有一个filter option，它允许指定哪些元素应该是可选的.将其设置为'.designer-field'即可解决问题.
Selectable has a filter option that allows to specify which elements should be selectable. By setting it to '.designer-field' it should solve the problem.
$(".designer-panel-body").selectable({
filter: '.designer-field'
});
