jQuery-UI可调整大小的错误与幻灯片动画

Question

我似乎无法弄清楚jQueryUI resizable函数正在做什么来导致我创建的“聊天框”div元素的锚点。问题是，当您通过拖动右上角调整此元素的大小时，它会正确调整大小，但是当您按下关闭按钮播放jQuery动画以折叠它时，它将以错误的方向折叠。如果您根本没有调整框的大小，则此折叠动画可以正常工作。

似乎还有另一个问题，即调整大小会导致框在页面上跳得更高，但这似乎只发生在Google Chrome上，Firefox工作正常，并且不确定原因！

尝试调整框大小，然后关闭它以查看问题：

$(document).ready(function() {
  // controls resizing of the chat box
  $('.chat_box').resizable({
    handles: 'n, e, ne',
    minWidth: 300,
    minHeight: 100,
    maxWidth: 700,
    maxHeight: 500,
  });
});

function minimize(chatId) {
  var bottom_bar = document.getElementById("bottom_bar");
  var box = bottom_bar.getElementsByClassName("chat_box")[chatId];
  var bar = bottom_bar.getElementsByClassName("chat_bar")[chatId];
  bar.className = "chat_bar chat_box_minimized";

  $(box).stop().animate({
      height: "0px",
      width: bar.offsetWidth,

Answer 1

从顶部手柄调整大小时，它会更改顶部坐标和高度。由于您使用底部设置位置，因此通常在动画处理时，高度将更改，但不会更改底部坐标。但只要可调整大小设置顶部坐标，就会生成动画但仍保留顶部坐标。

您可以执行的操作是使用调整大小回调来阻止在调整大小时设置顶部坐标。然后它会在动画上保持正确的方向，调整大小也会起作用。
