javascript - Jquery UI 可拖动不会调整其他 DIV 的大小

Question

In this plunk我有三个 DIV 除以另外两个可拖动(灰色)的 DIV。当可拖动的 DIV 被向上/向下或向左/向右拖动时，其他 DIV 应该调整大小。

第一个可拖动的 DIV 工作正常(左侧的那个可以垂直调整其他 DIV 的大小)。但是第二个可拖动的 DIV 不起作用，即使方法与第一个可拖动的 DIV 相同。有什么解决办法吗？

Javascript

    var top1H, bottom1H;
      $( "#div1" ).draggable({
          axis: "y",
          start: function(event, ui) {
            shiftInitial = ui.position.top;
              top1H = $("#top1").height();
              bottom1H = $("#bottom1").height();
            },
          drag: function(event,ui) {
              var shift = ui.position.top;
              $("#top1").height(top1H + shift - shiftInitial);
              $("#bottom1").height(bottom1H - shift + shiftInitial);
            }
        });

    var right1W, left1W;
  $( "#div2" ).draggable({
          axis: "y",
          start: function(event, ui) {
            shiftInitial = ui.position.left;
              right1W = $("#right1").height();
              left1W = $("#left1").height();
            },
          drag: function(event,ui) {
              var shift = ui.position.left;
              $("#right1").height(right1W + shift - shiftInitial);
              $("#left1").height(left1W - shift + shiftInitial);
            }
        });

    <div id="div1"></div>
    <div id="bottom1"></div>
  </div>
   <div id="div2"></div>
   <div id="right1"></div>

既然你提到你第一个可拖动的 DIV 工作正常，我只修复了第二个。

您的代码有两个问题:

1. 您为两个可拖动元素赋予了 axis: "y" 属性(而第二个元素应该在 X 轴上渐变。
2. 第二次拖动的变化应该是宽度(而不是高度)。

$(function() {
        var top1H, bottom1H;
        var right1W, left1W;
        
        $( "#div1" ).draggable({
            axis: "y",
            start: function(event, ui) {
                shiftInitial = ui.position.top;
                top1H = $("#top1").height();
                bottom1H = $("#bottom1").height();
            },
            drag: function(event,ui) {
                var shift = ui.position.top;
                $("#top1").height(top1H + shift - shiftInitial);
                $("#bottom1").height(bottom1H - shift + shiftInitial);
            }
        });
        $( "#div2" ).draggable({
            axis: "x",
            start: function(event, ui) {
                shiftInitial = ui.position.left;
                right1W = $("#right1").width();
                left1W = $("#left1").width();
            },
            drag: function(event,ui) {
                var shift = ui.position.left;
                $("#left1 div").width(left1W + shift);
            }
        });
    });

#div1 { 
  width:180px;
  height:6px;
  background-color:#e0e0e0;
  cursor:ns-resize;
  position: absolute;
}
#div2{
  width:6px;
  height:200px;
  background-color:#e0e0e0;
  float:left;
  cursor:ew-resize;
  left: 180px;
}
#top1{
  width:180px;
  height:100px;
  background-color:orange;
}
#bottom1 {
  width:180px;
  height:100px;
  background-color:blue;
}
#left1{
  width:0;
  height:200px;
  float:left;
  background-color:orange;
}
#right1{
  height:200px;
  background-color:red;
  width:100%;
}

Note that the code will NOT work if you drag the borders "outside" of the current block. To do so you will also need to check if the new width/height is bigger than the original and change all the elements accordingly.

更新 - 允许更改“红色”框的高度

(最好以“全页”模式查看)

$(function() {
  var minHeight = $('#right1').height();
  var top1H, bottom1H;
  var right1W, left1W;

  $( "#div1" ).draggable({
    axis: "y",
    start: function(event, ui) {
      shiftInitial = ui.position.top;
      top1H = $("#top1").height();
      bottom1H = $("#bottom1").height();
    },
    drag: function(event,ui) {
      var shift = ui.position.top;
      $("#top1").height(top1H + shift - shiftInitial);
      $("#bottom1").height(bottom1H - shift + shiftInitial);
      $('#right1,#div2').height(Math.max(
        minHeight,
        Math.max(
          $('#top1').height()+$('#div1').height(),
          $('#top1').height()+$('#bottom1').height()
        )));
    }
  });
  $( "#div2" ).draggable({
    axis: "x",
    start: function(event, ui) {
      shiftInitial = ui.position.left;
      right1W = $("#right1").width();
      left1W = $("#left1").width();
    },
    drag: function(event,ui) {
      var shift = ui.position.left;
      //$("#right1").width(right1W - shift + shiftInitial);
      $("#left1 div").width(left1W + shift);
    }
  });
});

#div1 {

This version will not give you the option to "lower" the height of your blocks once the height changed.
