jQuery旋轉元素可調整大小的問題

Question

我正在修整做一個jQuery UI調整大小在一個div旋轉77deg。結果是完全無法控制的。

複製此請：

• 轉到http://jqueryui.com/demos/resizable/
• 單擊帶有鍍鉻/ Mozila檢查安慰灰色可調整大小的元素應該是ID =「調整大小」。
• 應用-webkit-變換：旋轉（77deg）或-moz-變換：旋轉（77deg）
• 現在嘗試調整該元素

是有辦法解決這一問題？ 謝謝

Answer 1

手柄的鼠標移動尚未與元素一起旋轉。

如果您選擇合適的手柄（這將是接近底部，如果您使用rotate(77deg)，移動它離開將縮小元素的寬度，（這會出現類似的高度，由於旋轉。）

爲了相對於它的中心處的元件尺寸調整，則很有可能要更新由矢量鼠標移動調整大小的元件來調整寬度/高度的代碼。
