jQuery UI 可调整大小也可反向调整大小

Question

如何使 jQuery UI 可调整大小也可反向调整大小。

假设在html中有两个div标签，如果我向上调整大小意味着其他东西必须向下调整大小

<script>
        $(function() {
        $("#resizable").resizable({alsoResize: ".myiframe"});

    });
</script>
<div id = "resizable">
        This is the resizable content...
</div>

<div class="myframe">
   This must resize in reverse direction...
</div>

我尝试过但没有用请指导解决这个问题

Answer 1

通过修改 jQuery 用于实现 alsoResize 选项的代码，我们可以制作自己的 alsoResizeReverse 选项。然后我们可以简单地使用它，如下所示：

$("#resizable").resizable({
    alsoResizeReverse: ".myframe"
});

原始 alsoResize 选项的结构已在 jQuery UI 的各个版本中发生变化，我的原始代码在较新的版本中不起作用。我将给出在版本 1.8.1 和 1.11.4 中添加此功能的代码。

只需要更改一些内容，例如将 alsoResize 明显重命名为 alsoResizeReverse 并减去 delta 而不是添加它（是什么使调整大小反转）。原始的 alsoResize 代码从 jQuery UI 版本 1.8.1 和 版本 1.11.4。您可以在此处查看所需的一些更改。

要添加 alsoResizeReverse 功能，请将其添加到您的 javascript 中（这应该放在 document.ready() 之外）：

对于较新版本的 jQuery UI（示例基于 v1.11.4）：

$.ui.plugin.add("resizable", "alsoResizeReverse", {

    start: function() {
        var that = $(this).resizable( "instance" ),
            o = that.options;

        $(o.alsoResizeReverse).each(function() {
            var el = $(this);
            el.data("ui-resizable-alsoresizeReverse", {
                width: parseInt(el.width(), 10), height: parseInt(el.height(), 10),
                left: parseInt(el.css("left"), 10), top: parseInt(el.css("top"), 10)
            });
        });
    },

    resize: function(event, ui) {
        var that = $(this).resizable( "instance" ),
            o = that.options,
            os = that.originalSize,
            op = that.originalPosition,
            delta = {
                height: (that.size.height - os.height) || 0,
                width: (that.size.width - os.width) || 0,
                top: (that.position.top - op.top) || 0,
                left: (that.position.left - op.left) || 0
            };

        $(o.alsoResizeReverse).each(function() {
            var el = $(this), start = $(this).data("ui-resizable-alsoresize-reverse"), style = {},
                css = el.parents(ui.originalElement[0]).length ?
                    [ "width", "height" ] :
                    [ "width", "height", "top", "left" ];

            $.each(css, function(i, prop) {
                var sum = (start[prop] || 0) - (delta[prop] || 0);
                if (sum && sum >= 0) {
                    style[prop] = sum || null;
                }
            });

            el.css(style);
        });
    },

    stop: function() {
        $(this).removeData("resizable-alsoresize-reverse");
    }
});

对于旧 版本版本（基于 v1.8.1——我原来的答案）：

$.ui.plugin.add("resizable", "alsoResizeReverse", {

    start: function(event, ui) {

        var self = $(this).data("resizable"), o = self.options;

        var _store = function(exp) {
            $(exp).each(function() {
                $(this).data("resizable-alsoresize-reverse", {
                    width: parseInt($(this).width(), 10), height: parseInt($(this).height(), 10),
                    left: parseInt($(this).css('left'), 10), top: parseInt($(this).css('top'), 10)
                });
            });
        };

        if (typeof(o.alsoResizeReverse) == 'object' && !o.alsoResizeReverse.parentNode) {
            if (o.alsoResizeReverse.length) { o.alsoResize = o.alsoResizeReverse[0];    _store(o.alsoResizeReverse); }
            else { $.each(o.alsoResizeReverse, function(exp, c) { _store(exp); }); }
        }else{
            _store(o.alsoResizeReverse);
        }
    },

    resize: function(event, ui){
        var self = $(this).data("resizable"), o = self.options, os = self.originalSize, op = self.originalPosition;

        var delta = {
            height: (self.size.height - os.height) || 0, width: (self.size.width - os.width) || 0,
            top: (self.position.top - op.top) || 0, left: (self.position.left - op.left) || 0
        },

        _alsoResizeReverse = function(exp, c) {
            $(exp).each(function() {
                var el = $(this), start = $(this).data("resizable-alsoresize-reverse"), style = {}, css = c && c.length ? c : ['width', 'height', 'top', 'left'];

                $.each(css || ['width', 'height', 'top', 'left'], function(i, prop) {
                    var sum = (start[prop]||0) - (delta[prop]||0); // subtracting instead of adding
                    if (sum && sum >= 0)
                        style[prop] = sum || null;
                });

                //Opera fixing relative position
                if (/relative/.test(el.css('position')) && $.browser.opera) {
                    self._revertToRelativePosition = true;
                    el.css({ position: 'absolute', top: 'auto', left: 'auto' });
                }

                el.css(style);
            });
        };

        if (typeof(o.alsoResizeReverse) == 'object' && !o.alsoResizeReverse.nodeType) {
            $.each(o.alsoResizeReverse, function(exp, c) { _alsoResizeReverse(exp, c); });
        }else{
            _alsoResizeReverse(o.alsoResizeReverse);
        }
    },

    stop: function(event, ui){
        var self = $(this).data("resizable");

        //Opera fixing relative position
        if (self._revertToRelativePosition && $.browser.opera) {
            self._revertToRelativePosition = false;
            el.css({ position: 'relative' });
        }

        $(this).removeData("resizable-alsoresize-reverse");
    }
});

我在获取“Simen Echholt”代码与 jQuery 1.9.1/jquery-ui (1.10.2) 一起使用时遇到问题，但当我交换“$(this).data("可调整大小")" 与 "$(this).data("ui-ressized")"。

Answer 3

更新到 jQuery 2.1.1 和 jQuery UI 1.11.2。

$.ui.plugin.add("resizable", "alsoResizeReverse", {

  start: function() {
    var that = $(this).resizable("instance"),
      o = that.options,
      _store = function(exp) {
        $(exp).each(function() {
          var el = $(this);
          el.data("ui-resizable-alsoResizeReverse", {
            width: parseInt(el.width(), 10),
            height: parseInt(el.height(), 10),
            left: parseInt(el.css("left"), 10),
            top: parseInt(el.css("top"), 10)
          });
        });
      };

    if (typeof(o.alsoResizeReverse) === "object" && !o.alsoResizeReverse.parentNode) {
      if (o.alsoResizeReverse.length) {
        o.alsoResizeReverse = o.alsoResizeReverse[0];
        _store(o.alsoResizeReverse);
      } else {
        $.each(o.alsoResizeReverse, function(exp) {
          _store(exp);
        });
      }
    } else {
      _store(o.alsoResizeReverse);
    }
  },

  resize: function(event, ui) {
    var that = $(this).resizable("instance"),
      o = that.options,
      os = that.originalSize,
      op = that.originalPosition,
      delta = {
        height: (that.size.height - os.height) || 0,
        width: (that.size.width - os.width) || 0,
        top: (that.position.top - op.top) || 0,
        left: (that.position.left - op.left) || 0
      },

      _alsoResizeReverse = function(exp, c) {
        $(exp).each(function() {
          var el = $(this),
            start = $(this).data("ui-resizable-alsoResizeReverse"),
            style = {},
            css = c && c.length ?
            c :
            el.parents(ui.originalElement[0]).length ? ["width", "height"] : ["width", "height", "top", "left"];

          $.each(css, function(i, prop) {
            var sum = (start[prop] || 0) - (delta[prop] || 0);
            if (sum && sum >= 0) {
              style[prop] = sum || null;
            }
          });

          el.css(style);
        });
      };

    if (typeof(o.alsoResizeReverse) === "object" && !o.alsoResizeReverse.nodeType) {
      $.each(o.alsoResizeReverse, function(exp, c) {
        _alsoResizeReverse(exp, c);
      });
    } else {
      _alsoResizeReverse(o.alsoResizeReverse);
    }
  },

  stop: function() {
    $(this).removeData("resizable-alsoResizeReverse");
  }
});
$(function() {

  $("#resizable").resizable({
    alsoResizeReverse: ".myframe"

});

#resizable,
.myframe {

Answer 4

$('#div1').resizable({
        handles: 'n',
        resize: function(){
            $('#div2').css("height","-"+ui.size.height+"px");
        }
    }).bind("resize", function () {
        $(this).css("top", "auto"); //To handle the issue with top
    });

这也应该可以在相反的方向上调整另一个 div 的大小。

Answer 5

即使Simen发布的代码运行得很好，
这是我的代码，用于垂直调整两个 div 的大小（并且效果很好）

<script>
    var myheight  = ($(window).height()-50);
    var mywidth  = $(window).width();
    $(window).load(function () {
        $("#resizable").height(100); 
        $("#content").height(myheight-$("#resizable").height()); 
    });
</script>

<div id="resizable" style="border:1px solid #333; overflow:auto">resizable</div> 
<div id="content" style="border:1px solid red; overflow:auto">content</div> 

<script>
    $("#resizable").resizable({ 
        handles: 's', 
        maxHeight: myheight,
        resize: function() {
        $("#content").height(myheight-$("#resizable").height());
        }
    });
</script>

Answer 6

改编自玛格特和约瑟夫·贝克的想法——我认为这是一个更好的方法。此方法不需要任何 Jquery 库 hack 或插件即可将 div 分成两个窗格。只需在可调整大小的“resize”事件中添加一个函数来偏移宽度：

$("#left_pane").resizable({
  handles: 'e', //'East' draggable edge
  resize: function() {
    $("#right_pane").outerWidth($("#container").innerWidth() - $("#left_pane").outerWidth());
  }
});

这是完整的 JS fiddle。
