【中文标题】如何在使用 Resizable Jquery 增加 div 的大小时滚动？【英文标题】：How can I scroll while I increase the size of a div with Resizable Jquery? 【发布时间】：2019-05-31 21:23:24 【问题描述】：

我正在使用 AdminLTE 3 的模板，我有一个 div，由于 Jquery-UI 可调整大小，我可以增加它的高度，问题是当我尝试增加 div 的大小时，页面不会下降，而我展开 div。

我不想在div上放滚动条，我只是想让当我增加div的高度时，页面也会自动下降，用jquery或css

这是我的代码：

$(document).ready(function()


$("#main_row_About_results").resizable(
									handles: "s"
								);
                
                
);

正如您在尝试使用 jquery resizable ui 将 id = main_row_About_results 更高的 div 时看到的那样，主体不会自动下载。我只是希望只要我将 div 设置得更高，身体也会随着 div 自动下降（滚动）。现在这不会发生。我该怎么做？

【问题讨论】：

【参考方案1】：

您需要在调整大小时调整 scrollTop。有很多方法可以做到这一点。这是一个例子：

resize: function(event, ui)
  var rh = Math.round(ui.element.offset().top + ui.size.height);;
  var wh = $(window).height();
  var sp = $(document).scrollTop();
  var buff = wh + sp - 50;
  if (rh > buff) 
    $(document).scrollTop(rh - wh + 50);

计算可调整大小的偏移位置和当前高度为我们提供了文档中鼠标位置的适当数量。滚动顶部和窗口高度为我们提供了一个很好的比较数据。我们添加了一点缓冲区，50 像素，可以根据需要进行调整。

一旦满足条件，我们使用.scrollTop()移动滚动顶部。

工作示例

$(function() 
  $("#main_row_About_results").resizable(
    handles: "s",
    resize: function(e, ui) 
      var rh = Math.round(ui.element.offset().top + ui.size.height);;
      var wh = $(window).height();
      var sp = $(document).scrollTop();
      var buff = wh + sp - 50;
      if (rh > buff) 
        $(document).scrollTop(rh - wh + 50);
      
    
  );
);
